Wholesale Black Rice Extract 100% Natural High Quality Black Rice Extract Anthocyanin 25% With Free Sample

Anthocyanins belong to bioflavonoids, and the most important physiological active functions of flavonoids are free radical scavenging and antioxidant capacity. Studies have proved that anthocyanins are the most effective antioxidants and the most potent free radical scavengers discovered by mankind today, and the antioxidant performance of anthocyanins is 50 times higher than that of VE and 20 times higher than that of VC [13]. Purple sweet potato anthocyanin products have scavenging and inhibiting effects on -OH, H2O2, and other reactive oxygen species, especially on -OH scavenging ability is stronger than ascorbic acid, and scavenging effect is dose-dependent with concentration.
