Curcumin
In plain words
The short version
The yellow-orange pigment of turmeric — a widely loved clean-label natural colorant.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
ADI of 0–3 mg/kg body weight (EFSA 2010). Very low toxicity — turmeric has been consumed at dietary doses for millennia. Curcumin has poor bioavailability orally and is rapidly metabolized. Investigated as a nutraceutical for its anti-inflammatory and antioxidant properties, but the colorant-level intake is well below any pharmacological dose.
