Overview

Overview Information

7-keto-DHEA is a by-product of dehydroepiandrosterone (DHEA), a chemical that is formed in the body. DHEA is a "parent hormone" produced by glands near the kidneys. But unlike DHEA, 7-keto-DHEA is not converted to steroid hormones such as androgen and estrogen. Taking 7-keto-DHEA by mouth or applying it to the skin does not increase the level of steroid hormones in the blood.

People take 7-keto-DHEA to speed up the metabolism and heat production to promote weight loss. 7-keto-DHEA is also used to improve lean body mass and build muscle, increase the activity of the thyroid gland, boost the immune system, enhance memory, and slow aging.

How does it work?

7-keto-DHEA might promote weight loss by speeding up the body's metabolism.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Promoting weight loss. Developing research suggests that 7-keto-DHEA might significantly help obese women lose weight and fat.
  • Improving lean body mass.
  • Building muscle.
  • Increasing activity of the thyroid gland.
  • Boosting the immune system.
  • Enhancing memory.
  • Reducing signs of aging.
  • Other conditions.
More evidence is needed to rate the effectiveness of 7-keto-DHEA for these uses.
