What kind of interaction is it?

Synergy: a documented combination effect that is stronger or more useful than either substance taken alone.

Is this interaction backed by published research?

Yes. NutriStack lists 1 citation row for the Oligonol (Lychee Polyphenol) + Vitamin C pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Oligonol (Lychee Polyphenol) + Vitamin C

Q: Can I take Oligonol (Lychee Polyphenol) and Vitamin C together?

Yes. The combination of Oligonol (Lychee Polyphenol) and Vitamin C produces a measurable benefit. Oligonol is a polyphenol antioxidant and vitamin C is a water-soluble antioxidant; together they contribute complementary free-radical scavenging, and vitamin C can help recycle oxidized polyphenols, supporting overall antioxidant capacity.

Q: How does this affect a NutriStack Stack Score?

+2 to your Stack Score per scored synergy row.

SynergyEmerging evidence

What is happening. Oligonol is a polyphenol antioxidant and vitamin C is a water-soluble antioxidant; together they contribute complementary free-radical scavenging, and vitamin C can help recycle oxidized polyphenols, supporting overall antioxidant capacity.

Mechanism. Complementary antioxidant networks: vitamin C regenerates oxidized phenolic radicals and adds aqueous-phase radical scavenging alongside the polyphenol activity of Oligonol.

Recommendation. These can be taken together. No special separation is needed; combine at normal supplemental doses if antioxidant support is the goal.
