7-Keto is a naturally occurring substance found in small amounts in human blood and tissues, including the brain. Supplementing with 7-Keto may increase the production of T3, a thyroid hormone. The thyroid hormones play a role in determining the body’s basal metabolic rate which in turn may boost the body's metabolism.

It is important to note that, unlike other metabolites of DHEA, 7-Keto is not converted to sex hormones (either androgens or estrogens).

7-Keto also supports the immune system by helping the healthy function of white blood cells and antibody production.
