7-KETO-DHEA: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

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 for obesity, muscle strength, anxiety, depression, and other conditions. But there is no good scientific evidence to support these uses.

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 & Effectiveness ?

Insufficient Evidence for

Obesity. Early research shows that taking 7-keto-DHEA along with exercise might help obese adults lose weight.
A type of anxiety that often develops after a terrifying event (post-traumatic stress disorder or PTSD).
Aging.
Aging skin.
Anxiety.
Athletic performance.
Depression.
Memory.
Muscle strength.
Painful response to cold especially in the fingers and toes (Raynaud syndrome).
Other conditions.

More evidence is needed to rate the effectiveness of 7-keto-DHEA for these uses.

Side Effects

When taken by mouth: 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 and Warnings

When taken by mouth: 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. Pregnancy and breast-feeding: There isn't enough reliable information to know if 7-keto-DHEA is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Interactions ?

We currently have no information for 7-KETO-DHEA overview.

Dosing

The appropriate dose of 7-keto-DHEA depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for 7-keto-DHEA. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
