Instructions for using L-carnitine for weight loss

L-carnitine is an amino acid that is popular both in dietetics and sports nutrition, and in medicine. It allows you to solve many problems, including getting rid of excess weight and improving muscle tone. Another name is vitamin B11 or VT. This substance has excellent anabolic properties, improves cell nutrition, affects the accumulation of iodine in the thyroid gland, and accelerates tissue recovery processes. To achieve excellent results, you need to know how to take carnitine. This is exactly what we will try to figure out.

The role of carnitine in the body

L-carnitine is an amino acid, that is, a protein component. Like any other protein, it is part of almost all human cells.

Carnitine moves fatty acids into mitochondria, the body's “energy factory.” Thanks to this, excess fat is converted into energy. The transport function of carnitine is not limited to this. Another beneficial property is that L-carnitine binds toxins and removes them from the body.

It is assumed that L-carnitine has anabolic properties. But this mechanism has not yet been fully studied.

Another useful property is a decrease in the level of low-density lipoproteins in the blood. These substances are also called atherogenic, or harmful, cholesterol. An increase in their concentration in the body contributes to the deposition of fatty plaques on the vessel wall, which subsequently impede the movement of blood.

Additive properties

Speaking about the properties of the famous fat-burning amino acid, the following should be noted:

• ensures weight loss;
• improves protein absorption by muscles;
• oxidizes fats and converts them into energy, thereby increasing a person’s energy potential;
• lowers the concentration of bad cholesterol and triglycerides in the blood;
• improves the detoxification capabilities of the liver;
• strengthens the immune system;
• improves intellectual abilities.

In general, wherever you look, it’s a complete benefit.

What are the benefits of L-carnitine?

Considering the many functions that L-carnitine performs in the body, its beneficial properties are difficult to overestimate. Due to its ability to reduce cholesterol levels in the blood, this substance has anti-atherogenic properties. That is, carnitine reduces the risk of developing atherosclerosis. And this, in turn, reduces the likelihood of developing a heart attack or stroke.

They also do not deny the positive effect of L-carnitine on blood pressure and hormonal balance. There are studies claiming that regular intake of this amino acid increases intellectual abilities.

All of the beneficial effects of carnitine listed above apply to both women and men. But some of its properties are valid only for representatives of one gender or another. More about them below.

For women

The benefit of L-carnitine for women lies, first of all, in its fat-burning and anti-cellulite properties. It is recommended for use by all girls who want to lose weight. When combining the drug and aerobic physical activity, the effect will not be long in coming.

Regular intake of carnitine before training improves a girl’s immunity and helps maintain good health.

For men

The benefits and harms of L-carnitine for men are incommensurable. The positive properties significantly exceed possible adverse reactions. The main benefit for the stronger half is the rapid burning of excess fat in the body and the rapid increase in muscle mass.

A common problem that men face during prolonged intense exercise is interruptions in the functioning of the heart. After all, this muscular organ is subjected to heavy loads and must pump even more blood. This is where L-carnitine comes to the rescue again. Another beneficial property for the body is increasing the endurance of the myocardium (heart muscle).

Types of carnitine

Carnitine is a broad term that describes several different compounds. L-carnitine is the more common form of carnitine, found in the body and many supplements. Here are other forms of carnitine:

• Acetyl L-carnitine . This form, also known as ALCAR, plays a role in metabolism. It has neuroprotective properties that may help protect the nervous system ().
• D-carnitine . This type is an optical isomer (mirror image) of L-carnitine. It is toxic to the body as it can interfere with the absorption of other forms of carnitine ().
• L-carnitine L-tartrate . Athletes can use this species in the form of sports supplements. Research shows that it may be useful in reducing muscle pain and promoting recovery ().
• Propionyl-L-carnitine . This form exhibits analgesic and antirheumatic properties, and it may be beneficial for heart health ().

Is it possible to give L-carnitine to children?

Separately, it is worth noting the benefits and harms of L-carnitine for the child’s body. During intrauterine development of the fetus, its blood contains a large amount of this amino acid. It is transported from the mother's body through the placenta. But after birth, the concentration of carnitine rapidly decreases.

A healthy, full-term baby needs enough L-carnitine, which he receives through breast milk. But children with low body weight and congenital diseases need more energy. In such cases, additional administration of L-carnitine is indicated. It promotes weight gain and accelerated growth. Thus, the benefits of carnitine for premature babies are very great.

There is a disease in which the body's production of carnitine is impaired due to a congenital genetic defect. This is a direct indication for the administration of L-carnitine.

Attention! Carnitine can be given to children only after the recommendation of the attending physician. Self-medication is unacceptable!

Popular questions about carnitine

People who have taken carnitine for a variety of purposes note that they have improved overall health, increased performance and brain activity. There are many positive reviews from athletes who emphasize increased endurance during training and assistance in drawing relief during the drying period.

There are no less positive reviews from girls trying to lose excess weight. As an analysis of publicly available information shows, the only negative reviews about carnitine come from people who did not engage in training while taking the supplement, hoping only for its miraculous power. Their expectations were not met, which is quite natural.

We have selected the most frequently asked questions and prepared short answers to them so that you can form the most complete opinion about this drug and its action.

Questions	Answers
Is carnitine an amino acid?	No, but it arises by synthesis from two amino acids: methionine and lysine.
Does it affect the intrauterine development of the child?	Yes, since the embryo will receive the energy necessary for development exclusively from fatty acids. And their breakdown is impossible without the participation of l-carnitine.
Is it possible to get the required amount of l carnitine from prepared foods?	No, because it dies during heat treatment and is found in small quantities in products.
Why is L carnitine called a fake vitamin?	Because the body can synthesize it in small quantities on its own.
Is it possible to overdose when using carnitine?	This is only possible with regular and significant excesses of the daily dose, since unused residues are simply excreted from the body in the urine.
Is it possible to significantly lose weight with levocarnitine without training?	No, because its maximum concentration is in the muscles, and double fat burning occurs directly during physical activity.
Does it really increase the body's resistance to stress?	Yes, since carnitine is involved in the processes of protecting nerve tissue from harmful substances.
Is it possible to increase endurance during training if you take carnitine before it?	Yes, because due to its properties it increases the overall tone of the body.
How long can you take the drug without harming your health?	It is advisable to alternate courses every 2 months so that the body does not stop producing carnitine itself.
Is L-carnitine considered a medical drug?	It is included in many medications of various types, ranging from those that improve digestion to drugs for the treatment of male infertility. This is due to the critical need for this substance for the healthy functioning of the body.
Is it really prescribed for anorexics?	Yes, because it normalizes metabolic processes, stimulates appetite and promotes the growth of lean muscle mass.
Does levocarnitine cause side effects when used?	No, it is harmless to the body. Side effects can be caused by additional substances that the manufacturer includes in the drug. Read the ingredients carefully before use.

L-carnitine for pregnant and nursing mothers

The official instructions for the drug say that L-carnitine can be used by pregnant and nursing mothers. But this question still remains open. During pregnancy, nature has created optimal conditions for the development of the baby. And an additional load in the form of vitamin supplements or amino acids can disrupt the smooth process.

Despite all the beneficial properties of L-carnitine, here it can only cause harm. Not only a deficiency, but also an excess of protein in the body has a detrimental effect. You should be especially careful in the first trimester of pregnancy, when the formation of the internal organs of the fetus occurs.

Who is recommended to take L-Carnitine?

Indications for the use of l-carnitine include active sports. The substance helps athletes improve the body's performance, speed up the process of losing weight and improve muscle tone, and achieve better professional results. Also, the doctor may prescribe this substance to people with a lack of amino acids in the body. It is indicated older people to slow down the aging of the brain, improve concentration and memory, and people with heart disease. Also, amino acids are sometimes needed by pregnant and nursing mothers, small and premature babies, and newborns. The drug is prescribed for the treatment of obesity or anorexia. It is usually prescribed as part of complex therapy.

Symptoms of L-carnitine deficiency in the body

There are 2 types of L-carnitine deficiency in the body:

1. Systemic - develops due to dysfunction of proteins that move amino acids across cell membranes.
2. Myopathic - amino acid metabolism is disrupted only in muscle tissue; in other cells its level remains within normal limits.

Systemic L-carnitine deficiency is characterized by the following symptoms:

• deterioration in the contractility of the heart muscle, as a result of which the chambers of the organ expand (cardiomegaly);
• decreased intelligence, memory impairment;
• constant fatigue;
• anxiety;
• muscle weakness;
• decreased blood glucose levels (hypoglycemia).

The myopathic variant of carnitine deficiency is manifested by a decrease in the contractility of skeletal muscles and a deterioration in the conduction of nerve impulses in them. Clinically, this is manifested by severe weakness of the arms and legs and painful sensations. This condition is based on increased accumulation of lipids in striated muscles.

Dosage Recommendations

People who want to take L-carnitine should first consult a doctor. A doctor can make additional recommendations to support any treatment a person needs and can help them avoid possible reactions and interactions.

Most people tolerate L-carnitine well. The recommended dosage is approximately 1–3 grams per day. However, people with genetic disorders or other conditions that cause L-carnitine deficiency should talk to their doctor to determine individual dosage ().

Dosage forms of L-carnitine

There are several dosage forms of carnitine:

• ampoules;
• pills;
• capsules;
• syrup;
• powder.

1 ampoule contains 5 ml of the product with the active ingredient in an amount of 200 mg/ml or 400 mg/ml. 1 package contains 5 ampoules.

Carnitine capsules can be purchased in bottles of 60 or 150 pieces. Tablets are sold 10 pieces per plate.

L-carnitine is also available in the form of special drinks for sports nutrition.

Features of taking L-carnitine and dosage

The benefits and harms of L-carnitine for women and men depend on the dose. An amino acid overdose can lead to serious adverse reactions.

For carnitine deficiency, the drug is prescribed in the form of capsules or tablets that are taken orally. The dosage is calculated individually based on age and body weight.

If a person has impaired kidney function and is on hemodialysis, L-carnitine is prescribed in the amount of 2-4 g per day in the form of capsules or tablets. Possible intravenous administration with a dosage of 2 g per day after hemodialysis.

Parenteral (into a vein) L-carnitine is recommended for use in acute conditions. For acute myocardial infarction, the drug is administered in an amount of 200 mg per 1 kg of body weight. This dose is divided into 4 injections. Carnitine is administered slowly. Drip administration is also allowed for 48 hours without interruption. Then the dose of carnitine is reduced by 2 times. After the patient is discharged from the hospital, he is prescribed L-carnitine in tablets or capsules.

Consumption standards

Recommended daily doses of the vitamin may vary greatly in different countries because the biological role of the active substance has not yet been sufficiently studied. The following carnitine standards are accepted in Russia (table):

Age group	Amount of BT, mg
Infants	12-15
Children 1-3 years old	35-50
Children from 4 to 6 years old	60-85
Children 7-18 years old	100-300
Adults	250-300

The need for a vitamin-like substance increases significantly with constant overload of the body, pregnancy, and exposure to adverse factors. Expectant mothers and nursing women need to get up to 700-800 mg of carnitine from natural sources. Professional athletes and people who engage in heavy physical labor need 1000 to 2500 mg of B11 per day. Patients with chronic liver and kidney diseases, which are accompanied by an increased need for L-carnitine, are recommended to take up to 1000 mg per day.

To determine the level of L-carnitine, a urine test for the content of free active substance is most useful. To get an accurate result, it is forbidden to drink alcohol the day before taking the sample, and all diuretics are discontinued 48 hours before the test. Normal values ​​of free B11 for children over 2 years of age and adults are from 1 to 46 mmol. The total amount of vitamin normally ranges from 8.2 to 82.5 mmol.

How to take L-carnitine for weight loss

In order to lose weight, it is more advisable to take the drug by mouth: in the form of tablets, capsules, syrup or powder. Syrup is drunk in an amount of 5 ml 3 times a day. For people actively involved in sports, the dose can be increased to 15 ml. Drink carnitine in syrup half an hour before the start of training.

Capsules and tablets take 250-500 mg 3 times a day. Athletes can increase the amount to 500-1500 mg.

Attention! When increasing the dose of L-carnitine, the drug should be taken once a day!

The powder is drunk in the amount of 1 g per day. People who engage in professional sports are allowed a single dose of 9-15 g per day. But you shouldn’t abuse it! After all, then the harm can significantly exceed the benefit.

The course of taking liquid forms of L-carnitine is 1-2 months. You can repeat the course after a break of 2-3 weeks. The tablet form is taken for six months. It is not recommended to drink L-carnitine for longer than 6 months. A maximum of 6 courses are allowed per year.

How to take l carnitine for effective training: additional recommendations

It is worth understanding that even if you take l-carnitine as correctly as possible, but do nothing else, it will not only not help you lose weight, but can also lead to the opposite effect. This amino acid works only when you yourself work, so sports and proper nutrition are the main components of success.

Initially, activity is important. L-carnitine works to burn fat while you exercise. Moreover, it is cardio exercise that is important: running, brisk walking, cycling and exercise bike, aerobics, yoga, and so on.

Another important point is the duration of the workout. To get positive results, you need to practice for at least 25 minutes. First you need to activate the natural process of burning fat, and then the drug will kick in and enhance this process. You can take it both before and during your workout.

Much depends on nutrition. The body needs to be configured so that it itself activates the process of burning fat. This requires a clear nutrition plan. You need to eat often and in small portions, be sure to eat enough protein foods. After finishing your workout, try not to eat anything for an hour. Then you need to eat protein foods or drink a protein shake. Also remember to drink plenty of water. L-carnitine cannot be combined with strict and low-calorie diets.

What to eat while taking L-carnitine

The main benefit of L-carnitine is its fat-burning effect and the ability to build muscle mass. But no means will help in the absence of physical activity and proper nutrition. Therefore, when taking L-carnitine for the purpose of losing weight, a diet is required. It is necessary to exclude the following foods from the diet as much as possible:

• easily digestible carbohydrates (sweets, flour);
• fatty foods;
• fried foods;
• smoked meats and spices.

Preference should be given to vegetable fats, vegetables and fruits, lean meats (rabbit, chicken fillet).

How to protect yourself from side effects

One obvious side effect is increased hunger. This is due to the acceleration of metabolic processes in the body even at complete rest.

As a result, energy reserves are consumed, but appetite increases. But with proper nutrition and regular physical exercise, you can significantly reduce your hunger.

Nutritionists advise choosing not a low-calorie diet, but a protein-carbohydrate diet. With this diet, you need to eat at least 5 times a day, and you need to remove alcoholic beverages, tobacco, sweets and fatty foods from your diet. In addition to all this, you need to do strength training three times a week, and do cardio training up to 3-4 times.

Harm of L-carnitine and side effects

Much has been said about the beneficial properties of carnitine. But its incorrect use, and, in particular, overdose, can cause a lot of harm. Actually, L-carnitine does not harm the body. But there is also its isomer - D-carnitine, which has a toxic effect. With prolonged use of the L form, the body independently converts it into D. This is why it is not recommended to take carnitine for longer than 6 months.

Individual intolerance to L-carnitine is possible. Then, even with a single dose, nausea and vomiting occur. But this side effect occurs extremely rarely.

Some people experience insomnia because carnitine increases energy synthesis in the body.

The benefits and harms of L-carnitine for girls should also be considered from the point of view of the pros and cons of losing weight itself. After all, rapid loss of body weight can cause a lot of unpleasant effects:

• hormonal imbalance;
• infertility;
• accumulation of ketone bodies toxic to the body;
• deterioration in the functioning of the nervous system;
• disruption of the heart muscle;
• constant fatigue and weakness.

Indications for use

There are a lot of reasons for taking L-carnitine, starting with medical indications and ending with the all-familiar desire to improve your figure. Let's talk in more detail about the most common indications for using a vitamin-like component.

When there is a deficiency of a substance in the body

Many people think that since carnitine can be obtained from food, a deficiency is unlikely. Oh, how they are mistaken! It is useful to know that the body is capable of producing no more than 25% of the required daily dose of carnitine. If we consider that we most often eat food that has undergone heat treatment, then there is no need to even dream of preserving the substance in it - most of it is destroyed.

Therefore, almost all of us need an additional connection. To understand how much you have tortured your body, check out the signs of L-carnitine deficiency:

• fatigue even with minor physical activity;
• the appearance of cramps after or during sports;
• severe muscle tension after training, which does not go away for a long time;
• dizziness;
• feeling of lack of oxygen;
• the heart “jumping out” of the chest during sports training.

Found something of your own? L-carnitine can help you!

To replenish energy reserves

This point is especially relevant for people who play sports all day long or professionally. Their need for all useful components is always higher than that of lazy people lying on the couch.

Training takes a lot of energy - much more than we would like. Of course, you can make up for it by drinking a cool energy drink or stimulant. But this is fraught with problems with the nervous system.

If you don't want your eyes to twitch nervously when you see the gym door, it's better to use L-carnitine. You go longer with him, but further.

Taking the product before and during a workout significantly reduces fatigue, and the decrease in lactic acid levels allows you to perform complex exercises with heavy weights exactly as many times as originally intended (and without the puffing groans that make you think you've been crushed by a barbell).

When drying

Drying is the prerogative of purposeful and knowledgeable jocks. Thanks to it, the muscle relief becomes better drawn, which is always very beautiful. You can dry yourself with diet alone, but it’s difficult. If you add L-carnitine to the regimen, it’s much easier to get steel cubes that even a T-shirt can’t hide.

Prevention of fat deposits

There are people who are as thin as gophers all their lives, and there are those who only need to eat one pie and they immediately turn into cute, plump hamsters. So, the latter always need to be on guard of their figure. They even have to sleep hugging the scales.

To reduce the risk of gaining excess weight, you need to take L-carnitine in courses. Then the evolution from gopher to Khoma will not be so rapid.

For weight loss

L-carnitine is indicated for obesity not only because it delivers fatty amino acids to the mitochondria, where it goes wrong. Scientists have found that with a deficiency of this amino acid in the body, obesity develops. Therefore, there are no options! Are you prone to gaining weight or have you already eaten enough to survive on a desert island for a year? Use carnitine!

With high mental activity

People get tired not only from walking, running, jumping and carrying weights. Their brain also needs rest. Mental fatigue manifests itself:

• headaches;
• decreased concentration;
• memory impairment;
• lethargy;
• pressing sensations in the temple area.

The brain is just beating like a sledgehammer from the inside: “Vasily! Have a rest!" Hear the poor guy! Don't let it bend. L-carnitine releases energy. Part of it can go to the needs of the brain.

It also increases the overall tone of the body and enhances the production of endorphins. So even after a hard day at work, you will leave the office with a great mood and cleared brain hoses.

To speed up regeneration in old age

Old people, if they get sick, recover more slowly. Their fractures and paresis heal poorly. This is partly due to L-carnitine deficiency. The amino acid accelerates the course of regenerative processes, due to which all abrasions and cracks heal faster.

Reviews from doctors

Mironov Oleg Anatolyevich, 40 years old, Omsk

I am a nutritionist. A lot of girls come to me wanting to lose weight. In addition to a healthy diet, I prescribe L-carnitine for weight loss. It has a lot of useful properties. But we must remember that this is not a panacea. Efficiency is achieved only in combination with diet and physical activity.

Boyko Angelina Petrovna, 35 years old, Moscow

My specialty is cardiology. While everyone uses L-carnitine for weight loss, I prescribe it in the complex treatment of acute heart attack. Together with other drugs, it has a beneficial effect on the contraction of the heart muscle and normalizes the functioning of this organ.

Forms of release of dietary supplements

You probably already realized that the supplement is very cool. It is not surprising that sports nutrition manufacturers are experimenting with it and releasing it in various forms. They are trying to increase its digestibility, although the latter does not particularly need this (it already has all the indicators at its best!).

Pure 100% L-Carnitine

Classic option. It is most often used by athletes. A proven and reliable composition that does not let you down. It penetrates perfectly through mitochondrial membranes and forcefully drags behind it entire stacks of fatty acid molecules, consisting of long chains. Mitochondria perform the functions of a punisher - they break down those stinking fats to hell.

L-carnitine tartrate

It is a carnitine salt. When it enters the stomach, it is quickly metabolized into carnitine and tartaric acid (don’t be afraid - you won’t get drunk!). This combination accelerates the absorption of the compound.

Acetyl L-carnitine

This is carnitine that has been forced to bind to an acetyl group. Due to this, its bioavailability has increased, and with it its effectiveness.

According to some reports, acetyl L-carnitine has the ability to penetrate the brain and have a neurostimulating effect on it. Here's a robber!

You can easily recognize this form of carnitine. If this is what it contains, then Acetyl or Alcar will be indicated on the jar.

Propionyl L-carnitine

Propionylcarnitine is an ethereal form of a vitamin-like substance. A propionyl group is attached to it. Due to this, the component became not only fat-breaking, but also learned to improve myocardial function.

L-carnitine fumarate

Supplement formed by 100% pure carnitine and fumaric acid. Has a good effect on the cardiovascular system. But it also does not lose its abilities related to weight loss.

Frequently asked questions and their answers

I take L-carnitine before every sports workout. Should I take it on days when there are no workouts?

This remedy should be taken 2-3 times every day, on an empty stomach, in order to feel consistently good. It probably does not improve athletic performance in either athletics or bodybuilding. It only makes sense to take it before training to feel more energy and feel less lazy. Acetyl-L-carnitine is well suited for this purpose.

Is it possible to take L-carnitine along with fat burners?

The above describes the role L-carnitine plays for weight loss. Products that are marketed as fat burners are harmful to health. The administration of the site Centr-Zdorovja.Com does not recommend using them.

I am involved in bodybuilding. Will L-carnitine help build muscle?

Research shows no. People who report that L-carnitine has improved their performance in athletics or bodybuilding may be advised to simply eat more protein.

I'm a vegetarian. Is it worth taking L-carnitine to increase vigor and mental performance?

If you are overweight, at least a few kilograms, then you need to stop vegetarianism and switch to a low-carbohydrate diet. Otherwise, no supplements will help. If you are not overweight, but are worried about chronic fatigue and foggy thinking, then you can take L-carnitine for the heart or acetyl-L-carnitine to improve brain function. You can combine both of these additives.

Can minors take L-carnitine?

It is possible, but, as a rule, this is not necessary. L-carnitine is prescribed to minors to treat rare genetic diseases that cause a deficiency of this substance in the body. You can also take it if you are overweight to overcome your laziness to exercise. However, L-carnitine does not directly help you lose weight or improve athletic performance.

Can I take L-carnitine after gallbladder removal?

I guess, yes. Consult your doctor. Stop taking the supplement if you feel your condition worsens.

L-carnitine Optimum Nutrition L-carnitine 500

In what forms does this remedy exist?

L-carnitine comes in three popular forms:

• Regular L-carnitine (fumarate or tartrate);
• Acetyl-L-carnitine;
• Propionyl-L-carnitine, usually bound to the amino acid glycine, is called GPLC.

These supplements work in different ways. You can take them together to support your heart and brain function. But you should not take one instead of the other.

Regular L-carnitine and propionyl-L-carnitine act primarily on the cardiovascular system, while acetyl-L-carnitine acts primarily on the brain. The blood-brain barrier is a physiological barrier between the circulatory system and the central nervous system. It developed so that beneficial substances penetrate into the brain with the blood, but harmful substances cannot penetrate. Acetyl-L-carnitine overcomes this, but other types of carnitine do not.

• Jarrow-Formulas Acetyl-L-Carnitine - with Alpha Lipoic Acid
• Acetyl-L-carnitine + extended formula - for depression
• Acetyl-L-carnitine from Doctor's Best - increased dosage in each capsule

Acetyl-L-carnitine improves the energy supply to the brain and thus alleviates the symptoms of age-related problems with memory and concentration. This drug may slow the progression of Alzheimer's disease and help recover from a stroke. It, along with other supplements, helps against depression instead of “chemical” antidepressants. Try acetyl-L-carnitine if you want to reduce your addiction to coffee. This is a wonderful supplement that quickly gives a person vigor and clarity of thinking. The main thing is not to take it at night, otherwise you will not be able to sleep.

To treat cardiovascular diseases, you need to take not acetyl-L-carnitine, but regular L-carnitine or propionyl-L-carnitine. L-carnitine in the form of fumarate or tartrate is most often used. Why it is useful - you learned in detail above. Propionyl-L-carnitine is recommended for people who suffer from intermittent claudication. These are leg problems caused by atherosclerosis.

Diseases that may benefit from propionyl-L-carnitine

Intermittent claudication	Treatment with propionyl-L-carnitine capsules or intravenous injections increases pain-free walking distance in patients with established intermittent claudication.
Congestive heart failure	Patients with mild to moderate heart failure experience improved heart function and exercise tolerance
Low testosterone in older men	One study found that taking propionyl-L-carnitine along with acetyl-L-carnitine for 6 months worked well in older men. Their potency improved, they became more cheerful, and symptoms of depression disappeared.

Things to remember:

1. Take L-carnitine fumarate or tartrate to improve heart function, acetyl-L-carnitine for the brain, and propionyl-L-carnitine for intermittent claudication.
2. Different forms of L-carnitine can be taken simultaneously if there are indications for this.
3. Do not take acetyl-L-carnitine at night, otherwise you will not be able to sleep. Other forms of carnitine are also not advisable.

How and for how long to take it

The dosage of L-carnitine is 500-2500 mg per day. It is advisable to divide the daily dose into 2-3 doses of 500-800 mg. You need to take capsules on an empty stomach - 30-60 minutes before meals or 2-3 hours after meals.

L-carnitine dosages

Patient category	Dosage, mg per day
For prevention - elderly people, vegetarians	250-750
Angina pectoris, heart failure	2000-4000
After a heart attack, the first hours and days	2000-6000
Male infertility, weakened potency	2000 mg L-carnitine + 1000 mg acetyl-L-carnitine

This remedy must be taken continuously to feel consistently good. If you are worried about chronic fatigue or muscle weakness, and L-carnitine has made you more alert, continue taking it to maintain the achieved effect. This substance does not accumulate in the body, but is consumed every day. If you stop taking supplements, your health may return to its previous level within a few days.

If you are overweight, switch to a low-carbohydrate diet to reduce the concentration of insulin in the blood. This will eliminate chronic fatigue and daytime sleepiness. You will feel better within a few days. Perhaps changes in diet will be enough to stop L-carnitine and continue to feel normal. But if finances allow, then supplements for the heart and vigor - L-carnitine and coenzyme Q10 - are best taken continuously. At the same time, follow a diet and exercise.
