Curcumin

MODERATE EVIDENCEBotanicalLast updated

AVELOR SUMMARY

The bioavailability problem: native curcumin has <1% oral absorption. Solutions: BioPerine® (+2,000%), Meriva® (phospholipid), Longvida® (lipid particle), CurcuWIN® (hydrophilic carrier), Theracurmin® (nanoparticle). Each has different pharmacokinetics. 5 CYP pathways = most drug interaction-prone supplement. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*

Form comparison:

Form: Bioavailability: Notes

Curcumin + BioPerine/Piperine: 2,000% increase: Gold standard. Black pepper extract required for absorption.

Phytosome (Meriva): HIGH: Lipid-based delivery. Good clinical data.

Nano/liposomal: CLAIMS high: Limited comparative data. Marketing-driven.
