L-Carnitine is an amino acid which plays an important role in energy metabolism in three different ways: the metabolism of glucose, the production of energy from stored fats and as an antioxidant, protecting cells from oxidative damage as a result of metabolism.
A study by researchers from Pamukkale University, School of Medicine in Turkey, published in the journal Human Reproduction in July 2008 have discovered that women of normal weight who have PCOS have 50% less of the amino acid l-carnitine in their blood serum when compared to healthy women not diagnosed with PCOS.
They also found that here was a correlation between low serum l-carnitine levels and a high free androgen index (FAI) which strongly contributes to the growth of excess facial and body hair, and the loss of head hair in women with PCOS.
Another interesting correlation the researchers found was that higher l-carnitine levels were associated with higher sex-hormone binding globulin (SHBG), which is frequently low in women with PCOS.
