Do we benefit from taking L-Carnitine supplement?

Incredible Side Effects from Talking L-Carnitine!

There are a lot of buzz we hear around Carnitine and  how  we don’t need it because our liver and kidneys  make the substance in plentiful quantities and it is  stored in skeletal muscles, the heart, brain, and even sperm.   

In short - Carnitine is a substance that helps the body turn fat into energy. however if you are interested in the  3W’s (What, When, Where) please continue reading…..

Let’s start with how it’s being produced.

Carnitine, derived from an amino acid, is found in nearly all cells of the body. Its name is derived from the Latin carnus or flesh, as the compound was isolated from meat. Carnitine is the generic term for a number of compounds that include L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine.

Carnitine plays a critical role in energy production. It transports long-chain fatty acids into the mitochondria so they can be oxidized ("burned") to produce energy. It also transports the toxic compounds generated out of this cellular organelle to prevent their accumulation. Given these key functions, carnitine is concentrated in tissues like skeletal and cardiac muscle that utilize fatty acids as a dietary fuel.

What foods provide carnitine?

Animal products like meat, fish, poultry, and milk are the best sources. In general, the redder the meat, the higher its carnitine content. Dairy products contain carnitine primarily in the whey fraction. The carnitine content of several foods is listed below

Selected food sources of carnitine


Milligrams (mg)

Beef steak, cooked, 4 ounces


Ground beef, cooked, 4 ounces


Milk, whole, 1 cup


Codfish, cooked, 4 ounces


Chicken breast, cooked, 4 ounces


Ice cream, ½ cup


Cheese, cheddar, 2 ounces


Whole–wheat bread, 2 slices


Asparagus, cooked, ½ cup


Carnitine occurs in two forms, known as D and L, that are mirror images (isomers) of each other. Only L-carnitine is active in the body and is the type  found in food.

According to multiple sources, adults eating mixed diets that include red meat and other animal products obtain about 60–180 milligrams of carnitine per day. Vegans get considerably less (about 10–12 milligrams) since they avoid animal-derived foods. Most dietary carnitine(54–86%)  is absorbed in the small intestine and enters the bloodstream.

Based on multiple inputs from doctors, professional coaches and athletes say  the safe range for L-Carnitine intake should be from 500 – 2000 mg per day.

I leave you to do the math of how much meat or fish you have to consume to have enough of L-Carnitine.

While you are doing calculation I will just list the facts:


Fat Loss

If you are looking to get lean, then this is the amino acid you need. L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria, where they may be oxidized to produce energy. Carnitine has also been shown to reduce fatigue and serve as an appetite suppressant as well. Therefore, l-carnitine would be a major asset to have in your arsenal when you are dieting. It not only will help keep your body from storing fat, but it will increase your aerobic capacity to help you burn more calories.

Muscle Mass

L-Carnitine is also a great weapon for hardgainers looking to pack on muscle. Supplementing with l-carnitine can help you increase your strength and heavier weights mean bigger muscles in the long run.

Bone Mass

Aging bone loss is a major concern of many senior citizens and post-menopausal women. Of course this can lead to increased chances of fractures, osteoporosis, and arthritis among other bone diseases. Fortunately, by taking l-carnitine, you can slow down the bone loss process and improve bone micro structural properties by decreasing bone turnover.

Heart Conditions

Carnitine is primarily used for heart-related conditions. Several clinical trials show that L-carnitine can be used along with conventional treatment for angina to reduce the needs for medicine and improve the ability of those with angina to exercise without chest pain or discomfort. Some studies have determined that taking l-carnitine after a heart attack decreases the chances of suffering another one later. Carnitine has actually been given to help treat people with heart disease.


Kidney Treatment

Your kidneys produce carnitine so naturally when people have been diagnosed or may have kidney disease, carnitine is recommended to help make up for the deficiency of carnitine that your kidneys aren't producing.

Male Infertility

For those men that have been trying to have children and have low sperm counts, carnitine has been suggested and shown to help improve both sperm count and quality sperm.

Women Who Breast Feed

New mothers who choose to breast feed normally do so in part because of the number of calories it burns, but one side effect is it lowers your body's amount of carnitine. Even though you are sufficient in it while you are pregnant, taking extra carnitine can help prevent your body from being deficient. Combining both the breast feeding and the carnitine means that new moms will lose that baby weight faster.

Type II Diabetes

People that have Type II diabetes can also benefit from carnitine supplementation. Taking L-carnitine helps diabetics by increasing glucose oxidation, glucose storage, as well as glucose uptake.

Immune System

L-carnitine serves as an antioxidant that can help prevent damage done to your healthy cells by free radicals. This can help you out when you have a cold or are dealing with various seasonal allergies and training.

Brain Function

Seniors that can use something to help improve brain function has more than just gingko biloba to take. L-carnitine helps protect the brain from both age related and stress related damage to the brain which helps it function longer and better.

Antidote To Valproic Acid Poisoning

Although it may not be a bodybuilding issue, there are thousands of documented cases of valproic acid ingested every year. Despite not being able to serve as a total antidote on its own, taking l-carnitine is considered to help you if for some reason you do suffer from this dangerous poisoning.

We did a bit of digging to see what is available on the market today. Our criteria was to have L-Carnitine as pure as possible.and here what we found:

Now Foods  L-Carnitine best seller has other ingredients such as (Stearic Acid, Magnesium Stearate, Silica).

EverPure L-Carnitine has no other ingredients based on the Supplement Facts label.

BRI Nutrition L-Carnitine also best seller has Magnesium Stearate listed as other Ingredients.


Checking further revealed that 99% of the products that we compared have other ingredients such as (Stearic Acid, Magnesium Stearate, Silica, dibasic calcium phospate, rice flour etc.)

We also looked at liquid form of L-Carnitine, however based on the ingredient list we can't really compare it to the capsule or tablet based supplements.


We hope you find our blog helpful.
