L Carnitine Dosage

l carnitine dosageAs with any dietary supplement, please consult your doctor before taking L carnitine. Here are some typical L carnitine dosages you can discuss with them:

Regular L Carnitine Dosage: A typical recommended daily dosage is often L carnitine 500 mg to 1,000 mg. However it’s important to realize that L carnitine is reportedly known for boosting energy levels, similar to caffeine. Therefore it’s best to take before 3pm. Also, some nutritionists recommend co-supplementing acetyl L carnitine and alpha lipoic acid, because they are said to work best together.


 

There have been dozens of clinical trials which suggest L carnitine supplements may be very beneficial for a number of diseases and conditions, however the FDA has not evaluated any of these claims. It’s important to understand that L carnitine is only a dietary supplement (not medicine) and cannot be used for the diagnosis, prevention, cure, or treatment of a disease.

L Carnitine Dosage Weight Loss & Endurance
L carnitine reportedly supports weight loss in two different ways:

Fat Burning: Carnitine assists in the burning of fat. In fact, long chain fatty acids reportedly cannot be metabolized by your mitochondria without the aid of carnitine. While it’s true our bodies make carnitine naturally, there’s less produced as we get older. Furthermore, studies have suggested that L carnitine deficiencies appear more prevalent in obese individuals.

Energy Support: When taking a supplemental L carnitine dosage, one benefit is energy support. This makes sense, since carnitine supports cell mitochondria in burning long chain fatty acids, turning them into energy. Common sense also tells you that when a person has a healthy amount of energy, they’re more likely to be physically active, exercise, etc.

According to numerous online publications, the typical L carnitine dosage for weight loss seems to be between 1 to 3 grams (1,000 to 3,000 mg) daily. That being said, it seems to be more common to stick to the low end of that range.

L Carnitine Dosage For Heart
Perhaps some of the most promising benefits of L carnitine are those which are heart related. There have been quite a few clinical studies which have shown very exciting results, especially for angina.  Logically speaking, it makes sense since the heart is a muscle. It has been said that muscles get up to seventy percent of their energy through burning fatty acids.

According to the University of Maryland Medical Center website, here are the adult recommended supplemental L carnitine dosages for heart conditions:

Heart failure & Angina: 1.5 to 2 grams daily
Peripheral vascular: 2 to 4 grams per day
Heart disease: 600 to 1,200 mg taken 3 times per day, or 750 mg taken 2 times per day

Of course as a reminder, L carnitine is not medicine and should NOT be used to treat, cure, or prevent any of the above!

L Carnitine Dosage For Brain
What’s unique about acetyl L carnitine is that is has the ability to pass through the blood-brain barrier. Proper energy metabolism for the brain is vital since it makes up 20% of your body’s energy consumption. This is why research suggests L carnitine supplements are beneficial for degenerative brain conditions. The studies have had mixed results so far, so further research is needed. However this isn’t stopping many doctors and nutritionists from recommending acetyl L carnitine supplements for this purpose.

L carnitine dosage for this use varies greatly. There are some sources which recommend 250 mg to 300 mg to avoid possible side effects – such as nausea – which may occur in people who are sensitive to supplements. However there have been other sources which recommend the typical dosage of L carnitine 500 mg to 1,000 mg for supporting brain health. Others have recommended even higher. Consult your doctor to find out what would be best for you.

L Carnitine Dosage For Other Conditions
According to the University of Maryland Medical Center resource (discussed above) here are some other L carnitine dosages which were mentioned for specific conditions, but of course this should only be done under the direction of a physician:

Overactive thyroid: 2 to 4 grams daily, divided in 2 to 4 doses
Diabetic neuropathy: 3 grams daily
Male infertility: 300 mg 1,000 mg, three times per day
Chronic fatigue syndrome: 500 to 1,000 mg, 3 to 4 times per day

Important L Carnitine Dosage Warning
With the fatty acids being metabolized by the cells more efficiently, there is naturally an increase in electron flow that goes along with it. Inevitably, that may mean an increase in oxidative stress. In order to help balance these things out, some say it’s best to combine acetyl L carnitine & alpha lipoic acid (a powerful antioxidant and natural cofactor in mitochondrial enzymes). So ideally a two-in-one alpha lipoic acid acetyl L carnitine supplement.
