- 39.4% of products fall below the fairy-dust threshold (100 mg, 20% of the studied low dose).
- 28.0% of products don't disclose an amount because Curcumin (Curcuminoids) is declared inside a proprietary blend.

Search interest over time
How often people search for curcumin (curcuminoids) on Google, US only, the last 5 years. This is public interest, not DSLD label data — a spike here doesn't necessarily line up with anything on this page, and Google's own index (100 = that term's peak popularity in the chosen window) is relative, not an absolute search-volume count.

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.
Source: Cuomo J et al. 2011, J Nat Prod 74(4):664-669, PMID 21413691
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. Secondary reporting gives EFSA (2010, EFSA Journal 8(9):1679) and JECFA (2004) an ADI of 3 mg/kg bw/day for curcumin as a food colour; this was not confirmed from the primary EFSA/JECFA documents (access blocked) 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. The 500mg low end is a curated choice (the lowest commonly used standardized-extract dose), not a floor stated in the meta-analysis; the fairy-dust threshold follows from it.
- 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%.
