Black Rice Anthocyanins: The Potent Natural Antioxidant for Vision Support, Cardiovascular Health, and Skin Protection
description1
Product Description
Our Black Rice Anthocyanins are a high-purity, standardized botanical extract derived from the black rice bran of non-GMO black rice varieties (Oryza sativa L.) through advanced acid-alcohol extraction, resin purification, and concentration technologies. The product appears as a fine, free-flowing powder with a deep purple to dark red-purple color and a characteristic mild odor. It is standardized to contain a minimum of 25% anthocyanins (by UV-vis spectrophotometry, expressed as cyanidin-3-glucoside equivalents) and typically yields a total polyphenol content of ≥70%. With a CAS number 70892-78-1 and compliance with international food supplement and cosmetic standards, it is ideal for formulating capsules, tablets, powders, functional beverages, and skincare products targeting vision support, cardiovascular health, antioxidant protection, and skin vitality. The product is available in both spray-dried powder and microencapsulated forms to ensure stability and bioavailability.

Nutritional Composition
Black Rice Anthocyanins extract is a concentrated source of bioactive polyphenols. Its typical composition includes:
Total anthocyanins: ≥25% (cyanidin-3-glucoside, peonidin-3-glucoside, and others)
Cyanidin-3-glucoside (C3G): 15-20% (primary active component)
Total polyphenols: ≥70%
Moisture: ≤5%
Ash: ≤5%
It contains no significant fats, proteins, or carbohydrates beyond the polyphenol content. Free from preservatives, artificial colors, and GMOs (when sourced from non-GMO rice varieties).
Provides Potent Antioxidant & Free Radical Protection
Black rice anthocyanins exhibit exceptional oxygen radical absorbance capacity (ORAC), significantly higher than many other anthocyanin sources. Their ability to scavenge free radicals helps reduce oxidative stress markers and protect cells from environmental damage.
Supports Vision & Eye Health
Anthocyanins, particularly cyanidin-3-glucoside, have been shown to improve retinal blood circulation, accelerate rhodopsin regeneration, and protect against blue light-induced retinal damage. They help maintain visual acuity, reduce eye fatigue, and may slow the progression of age-related macular degeneration.
Promotes Cardiovascular Health & Blood Lipid Balance
Clinical studies indicate that black rice anthocyanins can reduce LDL oxidation, inhibit platelet aggregation, improve endothelial function, and lower serum lipid levels, contributing to the maintenance of healthy cholesterol profiles and overall cardiovascular wellness.
Exerts Anti-inflammatory & Metabolic Support
These bioactive compounds modulate inflammatory pathways by downregulating pro-inflammatory mediators (TNF-α, IL-6). Research has demonstrated their potential in supporting healthy glucose metabolism and improving insulin sensitivity in preclinical models.
