Dose distribution
Deciles of declared dose per serving (mg), among 1,409 products with a disclosed amount.
- 41.1% of products fall below the fairy-dust threshold (100 mg, 20% of the studied low dose).
- 28.2% of products don't disclose an amount because Curcumin (Curcuminoids) is declared inside a proprietary blend.

Forms explained
Typical standardization: >=95% total curcuminoids by HPLC (industry QC convention, also the reference material used in bioavailability trials)
Reference/baseline form in bioavailability studies; poor oral bioavailability from rapid intestinal/hepatic glucuronidation and sulfation, and low aqueous solubility.

Total curcuminoid plasma absorption ~29-fold higher than the unformulated standardized curcuminoid mixture in a randomized double-blind crossover human trial.

Reference values
- RDA (adult): not established — Not an essential nutrient; no RDA/AI exists.
- Tolerable Upper Intake Level (adult): not established — Not established as a supplement-safety UL by IOM/NIH ODS. EFSA/JECFA have an Acceptable Daily Intake for curcumin used as a food color additive (E100), a food-safety regulatory context distinct from a dietary-supplement UL -- exact current mg/kg-bw/day figure was not independently re-confirmed (source blocked automated fetch) and should not be conflated with a supplement UL.
- Studied clinical dose range: 500–2000 mg
- Zeng L et al. 2021, Biosci Rep 41(6):BSR20210817, PMID 34017975 -- meta-analysis, 15 RCTs/1,621 participants for osteoarthritis; doses across trials ranged ~40mg (nanocurcumin) to 2000mg/day; significantly lower WOMAC pain scores vs placebo (SMD -0.66), efficacy comparable to NSAIDs with better tolerability.
- Note: Standardization: labels commonly declare >=95% total curcuminoids (curcumin + demethoxycurcumin + bisdemethoxycurcumin, by HPLC) -- an industry/manufacturing QC convention (matching the reference material used in bioavailability trials), not itself a proven potency threshold distinct from e.g. 80-90%.
