The study found that gamma oryzanol exhibited significant antioxidant activity in the inhibition of cholesterol oxidation.


Gamma Oryzanol:
What it is, what it does & how it works...

Gamma oryzanol is a mixture of antioxidant compounds that occurs naturally in rice bran oil. Gamma oryzanol is believed to improve muscle tone and performance, which has made rice bran oil a popular supplement among athletes and animal breeders. Gamma oryzanol is one of nature’s most powerful antioxidants, which are known to protect against heart disease, cancer, and other illnesses. Gamma oryzanol was first extracted from rice bran oil in Japan in 1953, and rice bran oil has since gained a reputation as the world’s healthiest seed oil.*


The science behind the supplement


Gamma oryzanol is a collection of ferulated sterols, which the body can metabolize to provide circulating ferulic acid. These ferulic acid esters are thought to have a positive impact on hormone function, resulting in anabolic effects on muscle growth and the reduction of fatigue. Studies have indicated that gamma oryzanol also activates the higher center of the endocrine system and the automic nervous system, helping to promote balance in both systems.


Gamma oryzanol shown to be effective in scientific study


The antioxidant activities of gamma-oryzanol from rice bran were investigated in a study1 published in the Journal of Agricultural Food Chemistry. The study found that gamma oryzanol “exhibited significant antioxidant activity in the inhibition of cholesterol oxidation.” Gamma oryzanol components of rice bran oil were also shown to have greater antioxidant properties than vitamin E.

Magic after taking Gamma

Dear Springtime:


I've enclosed photos of SC Splash's Valley Girl, alias Magic. She has been on Springtime Gamma. The difference in her haircoat and muscling is amazing. I've used Gamma before on a mare I showed in halter with the same great results. Thanks for a great product!
