Bevisning gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Säkerhet caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Säkerhet signals
Exceeds upper intake limit — curcumin
1000.0 mg per portion exceeds the tolerable upper intake level of 210.0 mg/day. EFSA Acceptable Daily Intake (ADI) is 3 mg/kg bw/day (≈210 mg/day for a 70 kg adult); FDA GRAS notifications support up to 1,000 mg/day, and short-term trials have used 8-12 g/day safely for up to 3 months.

Liver safety signal — curcumin
Cases of drug-induced liver injury associated with curcumin/turmeric supplements have been reported. Most involved formulations with enhanced bioavailability (phytosome, nanoparticles) or doses above 1,000 mg/day. EFSA set an ADI of 3 mg/kg bw/day (≈210 mg/day for 70 kg). Doses up to 1,000 mg/day of standard extracts have been generally tolerated in trials.

Drug interaction risk — curcumin
Inhibits CYP2C9 and CYP3A4 (moderate effects on CYP2B6, CYP1A2, CYP2D6). Interacts with warfarin and other vitamin K antagonists (elevated INR reported), NSAIDs, antiplatelet agents, antihyperlipidemics, and reduces iron absorption via chelation.

Redaktionellt notes

This is a generic 95%-curcuminoid turmeric extract, not the patented, bioavailability-enhanced Curcumin C3 Complex (Sabinsa) the brief asked about, BulkSupplements does not appear to sell C3 Complex specifically; no piperine/BioPerine or lipid delivery system is included to boost the notoriously poor absorption of curcumin.
