About Rice Bran
The bran layer of rice, a source of fiber, gamma-oryzanol, tocotrienols and phytosterols. Whole rice bran has limited direct clinical evidence; specific fractions (gamma-oryzanol, tocotrienols) have their own, better-studied profiles.
What Rice Bran supports
- Source of fiber and phytonutrients; limited evidence for the whole bran itself
