Gamma Enterprises is a well-known player in the dietary supplement circuit. In 2004, they founded a subsidiary, Gamma Labs, to handle their dietary-supplement products. Gamma Labs manufactures supplemental products that they say naturally boost testosterone and estrogen levels.

Gamma-O is Gamma Labs signature line of dietary supplements. This line includes a supplement for male athletes, a mind and body enhancer with pomegranate, a testosterone booster for “every man,” a supplement for female athletes, a supplement for menopause, and a multi-vitamin for women.

Product Features

Gamma Enterprises’ best-known products contain “Gamma Oryzanol,” a rice bran oil. Rice bran oil is taken from the rice germ and inner husk. This essence is thought to include health-benefiting compounds (i.e. vitamin E, oryzanol [an antioxidant], and phytosterols). The health benefits of rice bran oil are well-known. These benefits may or may not be present in dietary supplements that use the extract. Rice bran oil will primarily benefit those who already engage in a healthy lifestyle (i.e. healthy diet and regular exercise).

Gammo-O with Pomegranate contains several fillers: gelatin, FD&C Blue 1, FD&C Blue 2, FD&C Red 40, FD&C Yellow 6. Positively Pink also contains several fillers which are listed under “other ingredients above.” These ingredients have no known health benefit. One ingredient, magnesium stearate, may in fact be counter-productive. It may coat the inner-lining of the stomach preventing the body from properly absorbing the ingredients in this supplement.
