Ask The Trainer #79 - Carnitine for Testosterone

QUESTION:

Hi. I recently read an article that said supplementing l-carnitine worked well for raising natural testosterone levels. Do you know if there’s any legit evidence to back this up? Thanks in advance.

ANSWER:

Hi, Gary. L-carnitine is an amino acid commonly found in meats and fish. It’s a compound that’s essential to our survival. L-carnitine deficiencies can lead to some serious health like muscle weakness, cognitive diseases, hepatic (liver) dysfunction, and cardiomyopathy (heart disease). Since meats and fish are the best sources of carnitine, vegans are more susceptible to l-carnitine deficiencies and should seriously consider supplementing with this amino acid.

The human body does have the ability to synthesize l-carnitine from the amino acids methionine and lysine. This process is initiated by vitamin C dependent enzymes. Therefore vitamin C deficiencies can inhibit l-carnitine biosynthesis within the body.

L-carnitine is commonly added to a variety of diet and sports nutrition products because of its notoriety as a potential fat burner and testosterone booster. Research has shown that l-carnitine plays a significant role in transporting fatty acids into the mitochondria of cells to be used as energy. Moreover, studies have also shown that androgen receptor (AR) activity within these same cells is also increased.

This is significant to testosterone levels because androgen receptor AR is a nuclear receptor that is activated by binding androgenic hormones, such as testosterone or dihydrotestosterone, into the cytoplasm and then transporting them into the nucleus of the cells.

That being said, l-carnitine doesn’t actually make your body produce more testosterone. However, your brain and body become more sensitive to your existing testosterone because of that increase in receptors. In turn, this increase may potentate the desired superpowers of testosterone, such as increased energy, increased libido, increased strength, increased motivation, and increased confidence.

One study I read demonstrated that subjects who supplemented 2 grams of l-carnitine tartrate per day significantly increased androgen receptor (AR) within 3 weeks:  http://www.ncbi.nlm.nih.gov/pubmed/16826026

Although supplementing l-carnitine alone won’t actually increase the synthesis of testosterone, it may actually help your body make better use of the testosterone it already produces. I think it would make a great companion to a trustworthy natural testosterone boosting supplement like Test Charge, which actually can increase testosterone synthesis.

I hope this answers your question. I wish you all the best of success in achieving your goals!
