A Wonder Neutraceutical
Gamma-Oryzanol is a naturally occurring component in rice bran and rice germ which consists of a mixture of ferulic acid esters of sterols and triterpene alcohols.
In 1954, Kaneko and Tsuchiya et al. reported that isolated oryzanol demonstrated nutritional effects on animals. Afterwards, it was widely accepted round the world as a natural dietary supplement, health supplement, muscle builder, sports supplement, medicine to treat various diseases etc. There are increasing number of reports indicating the benefits, efficacy and safety of gamma-oryzanol. Gamma-oryzanol has been used as a medicine in Japan since the year 1962.
