DHEA, short for dehydroepiandrosterone, is a steroid which is found in abundance in humans. DHEA seems to be involved in a variety of biological effects in mammals, produced by the adrenal glands, but also being synthesized in the brain, it manipulates the androgen receptor indirectly and directly, if indirectly then through metabolites. Considered a neurosteroid, it can be also viewed as a prohormone for the gonadal steroids. DHEA is produced by means of two cytochrome P450 enzymes from cholesterol. As a supplement it continues to be of widespread importance and popularity, particularly within the body building communities.

Vitamin E is commonly found in food sources like eggs, milk, nuts, seeds, vegetable oil like olive oil, wholegrain foods, wheat germ, red palm oil, but also in asparagus and avocado fruits.
