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.

Benefits

✓Reduces inflammation and inflammatory markers

✓Antioxidant protection against oxidative stress

✓Supports joint health and mobility

✓May enhance cognitive function and neuroprotection

✓Supports digestive and gastrointestinal health

Dosage

Typical Dose

500-2000 mg daily (with black pepper/piperine for absorption)

Upper Limit

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.
