Awarded 5 US Patents** 7-KETO® is a substance found naturally in the body and is primarily produced by the adrenal glands. 7-KETO® is metabolozed from DHEA, and similar to DHEA, 7-KETO® levels have been known to decline with advanced age. However, unlike DHEA, 7-KETO® does not convert to estrogen or testosterone. This lack of conversion with 7-KETO® may be beneficial since over production of these two hormones can lead to unwanted side effects.* No sugar, salt, starch, yeast, wheat, gluten, corn, fish.
