Koala sleeping

Are you struggling to make it through the day? Do you often feel bogged down by exhaustion and like you are running on empty? If so its sounds like you may benefit from L-Carnitine supplementation.

When you hear the word L-Carnitine, thoughts of an exotic health conditions or complex bodily processes may come to mind. However, L-Carnitine is a substance made in the body consisting of two amino acids and its purpose is to transport fatty acids into our mitochondria so that they can produce energy.  Having thriving mitochondria full of fatty acids helps protect us from oxidative damage. L Carnitine is often found in its acetylated form (Acetyl L Carnitine), which can cross the blood brain barrier more readily than the non-acetylated L-Carnitine. This does not dampen the improved energy people feel from taking L-Carnitine since close to 98% of it is stored in your muscles (1).

In one study, 66 elderly subjects who were 100 years or older ingested two grams of L Carnitine for one month (2). The subjects at the end of the study reported having an increase in muscle mass and energy level.

For the younger more active population L-Carnitine may improve muscle recovery, stamina and reduce muscle soreness (3)(4)(5).

Dosages ranging from 1-3 grams appear to hold the most benefits for an individual. But be careful if you have a thyroid disorder. L-Carnitine can lower thyroid hormones.
