Anthocyanins (Bilberry Extract) + Vitamin C

Q: Can I take Anthocyanins (Bilberry Extract) and Vitamin C together?

Yes. The combination of Anthocyanins (Bilberry Extract) and Vitamin C produces a measurable benefit. Vitamin C and bilberry anthocyanins are complementary antioxidants. Ascorbate can help regenerate and stabilize flavonoid antioxidants, and the combination is commonly used to support capillary integrity and general antioxidant defense.

Q: How does this affect a NutriStack Stack Score?

+2 to your Stack Score per scored synergy row.

SynergyEmerging evidence

What is happening. Vitamin C and bilberry anthocyanins are complementary antioxidants. Ascorbate can help regenerate and stabilize flavonoid antioxidants, and the combination is commonly used to support capillary integrity and general antioxidant defense.

Mechanism. Ascorbate participates in redox cycling that can spare and regenerate oxidized flavonoid radicals, and both nutrients independently support collagen and vascular endothelial function.

Recommendation. These can be taken together safely with food. No special separation is needed; combine within normal dietary or supplemental ranges.
