Curcumin (Turmeric)

herbs

Curcumin is the active polyphenol compound found in turmeric (Curcuma longa), a spice used for centuries in traditional medicine. It is recognised for its potent anti-inflammatory and antioxidant properties, though absorption is naturally poor without enhancement. Modern supplementation typically uses bioavailability-enhanced formulations to maximise therapeutic effects.

8000 mg daily (long-term safety data limited above 2000 mg)

Timing

With meals containing fat to enhance absorption; split into 2-3 doses

Forms & Bioavailability

Standard curcumin extract

Poor absorption (5-10%); significantly enhanced when combined with piperine

Curcumin with piperine (black pepper extract)

20-fold increased absorption; most common and effective form

Phospholipid-bound curcumin (phytosome)

Superior absorption; enhances cellular uptake and distribution

Liposomal curcumin

Excellent bioavailability; protects compound and enhances delivery

Side Effects

Gastrointestinal upset, nausea, or diarrhoea at higher doses
Headaches in some individuals
Mild skin reactions or allergic responses (rare)
Yellow discolouration of skin or sclera at very high doses

Interactions

May potentiate anticoagulants and antiplatelet drugs (warfarin, aspirin)
Can inhibit CYP3A4 and CYP2C9 enzymes, affecting drug metabolism
May reduce absorption of iron and other minerals if taken simultaneously
Potential interaction with diabetes medications affecting blood glucose
May increase effects of NSAIDs and other anti-inflammatory agents

Research Summary

Extensive clinical research supports curcumin's anti-inflammatory and antioxidant effects, with promising evidence for joint health, cognitive support, and gastrointestinal function. However, poor bioavailability of standard curcumin has historically limited clinical efficacy; enhanced formulations with piperine or phospholipid delivery show significantly improved outcomes in human trials. Further long-term safety data is needed for doses exceeding 2000 mg daily.
