Overview

Overview Information

7-keto-DHEA is formed from dehydroepiandrosterone (DHEA) 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 metabolism and heat production, which can 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. It is also used to treat depression, anxiety, and post-traumatic stress disorder (PTSD).

How does it work?

7-keto-DHEA might promote weight loss by speeding up the body’s metabolism and converting more energy to heat instead of storing it as fat.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Promoting weight loss. Early research shows that taking 7-keto-DHEA along with exercise might help obese adults 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.
  • Depression.
  • Anxiety.
  • Post-traumatic stress disorder (PTSD).
  • Other conditions.
More evidence is needed to rate the effectiveness of 7-keto-DHEA for these uses.

Side Effects

Side Effects & Safety

7-keto-DHEA is POSSIBLY SAFE when taken by mouth for up to 8 weeks. It might cause mild side effects such as nausea, dizziness, or low blood pressure in some people.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of 7-keto-DHEA during pregnancy and breast-feeding. Stay on the safe side and avoid use.
