Origin & History
Black Rice Bran Fiber is sourced from the outer bran layer of black rice (Oryza sativa L.), a grain historically cultivated across Asia. This fiber-rich ingredient retains the grain’s deep pigmentation and exceptional nutritional complexity. It is celebrated for its high antioxidant content, particularly anthocyanins, offering significant benefits for digestive, cardiovascular, and metabolic health.
“Black rice, historically known as "forbidden rice," was highly prized in imperial China for its rarity and medicinal properties, traditionally reserved for royalty. While the whole grain has long been revered, its bran, once a byproduct, is now recognized for its concentrated fiber and antioxidant power. This ingredient bridges ancient reverence for black rice with modern scientific appreciation for its functional components.”Traditional Medicine
Scientific Research
Scientific research validates the significant health benefits of black rice bran fiber, particularly its rich anthocyanin content, which is linked to oxidative stress reduction and improved vascular health. Numerous studies confirm that the fiber components of rice bran contribute to cholesterol-lowering effects, enhanced glycemic control, and overall gut health. These findings are supported by a combination of in vitro, animal, and human dietary intervention studies.
