Shilajit boosts concentration of testosterone, free testosterone and DHEA
Men synthesise more testosterone if they take 500 mg shilajit daily. Researchers at J.B. Roy State Ayurvedic Medical College and Hospital in India discovered this after doing experiments on men aged 45-55. Their study has been published in Andrologia.
Shilajit
These supplements are effective, Indian researchers concluded in 2012 in a sponsored study. In patents the active substances in shilajit are listed as dibenzo-alphapryones [structural formula shown below]. [US patent 20050245434]
Study
The researchers gave half of the men 2 capsules a day, each containing 250 mg shilajit extract. The other half got a placebo.
Results
However, the increased synthesis of DHEA and testosterone had no effect on the production of the messenger hormones LH and FSH, as these did not decrease. How this was possible, the researchers don't know.
