Supplement
7-Keto DHEA is a compound the body makes as a byproduct of the hormone DHEA, though unlike DHEA it does not convert into sex hormones. People mostly look at it for weight management in obesity, and the evidence is very limited: small studies hinted at a slight rise in resting metabolic rate and some fat loss. Both findings came from manufacturer-funded or conflict-of-interest research in a few dozen people, and blood sugar and blood pressure showed no clear difference.
