Gamma Oryzanol Supplement Guide: May Help Boost Testosterone Levels!
What is it and where does it come from?
Gamma Oryzanol is a mixture of plant sterols and ferulic acid esters that are derived from barley, corn and rice.
The majority of gamma oryzanol used in nutritional supplements is harvested in Japan. It is also known as calclate, gamma-oz, gammariza, oryzanol, oz, and thiaminogen.
What does it do and what scientific studies give evidence to support this?
Gamma oryzanol has been used to treat medical conditions, including heart burn, nausea, vomiting, under active thyroid, physical injuries, and muscular aches and pains.
Gamma Oryzanol stimulates the release of endorphins - the body's so-called "feel good" hormones. These hormones stimulate the pleasure centers of the brain, and this stimulation results in an elevation of mood.
Gamma Oryzanol has been proven to have very strong antioxidant activity. In fact, one study showed that it was up to ten times stronger than vitamin E for scavenging free radicals from the body and preventing tissue damage that results from free radical action.1
As a nutritional supplement, gamma oryzanol has become popular among athletes and bodybuilders because it may boost strength, increase muscle gain4, reduce body fat, speed recovery and reduce post-exercise soreness. Elevated testosterone levels are thought to be responsible for these effects.5

Healthy adults can benefit from supplementing with gamma oryzanol.
How much should be taken? Are there any side effects?
