Curcumin: Safe, Regulated Health Applications and Culinary Use

Curcumin, the bright yellow polyphenol from Curcuma longa (turmeric), is well-known as a spice, food color (E 100), and as a dietary supplement. This article outlines its EFSA‑approved uses, health claims, and safety profile—based solely on scientifically substantiated and regulated information.

1. EFSA‑Approved Roles

1.1 Food Additive and Colorant

  • Curcumin is authorized in the European Union as a food color (E 100).

  • EFSA confirmed it is not carcinogenic, based on extensive evaluations.

  • An Acceptable Daily Intake (ADI) was set at 3 mg/kg body weight/day, equivalent to approx. 210 mg/day for a 70‑kg adult.

1.2 Novel Food Safety Assessment

  • A specific derivative, tetrahydrocurcuminoids, received EFSA approval as a novel food for use in supplements at doses up to 140 mg/day.

2. Safety Profile

ADI and Exposure

  • EFSA’s ADI of 3 mg/kg bw/day stems from reproductive toxicity data; typical food intake only amounts to ~7% of this threshold, well below risk levels.

Toxicity & Risk

  • Generally non‑genotoxic and non‑carcinogenic.

  • Skin, eye, respiratory tract irritant in high‑purity extracts .

  • Rare liver toxicity cases reported—from high-dose supplementation.

Quality and Adulteration

  • Some turmeric powders have been found adulterated with lead chromate or illegal dyes; poor-quality batches pose health hazards.

3. Practical Guidance

3.1 As a Spice or Colorant

  • Using turmeric in cooking carries no known risk under EFSA guidelines.

  • Typical culinary intake remains far below the ADI.

3.2 As a Supplement

  • Stick to ≤ 3 mg/kg bw/day of curcumin or turmeric extract, which includes colorant use.

  • For tetrahydrocurcuminoid supplements, limit to 140 mg/day, per EFSA’s safe novel food conclusion.

  • Always choose reputable brands that test for purity and absence of contaminants.

3.3 Safety Tips

  • Slight risk of allergic skin contact—perform a patch test if you're sensitive.

  • Monitor for unexplained liver symptoms (e.g., fatigue, jaundice)—discontinue use if they arise.

  • Avoid high-dose supplements during pregnancy or if on medications without consulting a doctor.

4. Summary Table

Use Case EFSA Status Safety & Guidelines
Food colorant (E 100) Approved; ADI 3 mg/kg bw/day  Use in cooking is safe
Tetrahydrocurcuminoid supplement (140 mg/day) Novel food approved Safe up to 140 mg/day
High-dose curcumin supplements Overdose risk; liver injury reported Avoid above ADI without monitoring
Adulteration risk Documented Buy certified, tested products

5. Conclusion

Curcumin and its derivatives are safely used in food and certain supplement formats under EFSA guidance.

  • No proven clinical health claims (e.g., joint support) are currently EFSA‑authorized.

  • Stay within recommended intake limits and opt for high‑quality, tested supplements to minimize risk.

Glossary

  • ADI: Acceptable Daily Intake

  • bw: Body weight

  • Novel food: Substance requiring safety review before EU market approval

Curcumin remains a vibrant spice and food additive with a strong safety record—when consumed responsibly. However, shoppers should be cautious of unverified health claims and choose supplements carefully.
