Curcumin
Also known as Turmeric extract
Curcumin is the main active polyphenol in turmeric, studied for anti-inflammatory and antioxidant effects, especially in joint comfort. Its biggest limitation is poor absorption, which is why it is almost always paired with piperine or formulated for bioavailability.
Benefits
Eases joint discomfort
ModerateMay reduce symptoms of osteoarthritis comparably to some over-the-counter options.
Anti-inflammatory and antioxidant
ModerateModulates inflammatory signaling pathways.
Pros & cons
Pros
- Good evidence for joint comfort
- Strong safety record
Cons
- Very poorly absorbed on its own
- Can interact with blood thinners
Side effects
Mild digestive upset
Generally well tolerated; occasional GI discomfort.
How to take it
Typical dose
500–1,000 mg of curcumin per day (with absorption enhancer)
Timing
With food and a source of fat or piperine
Common forms
Tip: Plain turmeric powder contains only ~3% curcumin and absorbs poorly.
What the research says
Curcumin and osteoarthritis
ModerateTrials suggest reduced joint pain and improved function, often comparable to NSAIDs with fewer GI effects.
Curcumin bioavailability with piperine
StrongPiperine substantially increases curcumin absorption in pharmacokinetic studies.
How it connects
Relationships between Curcumin and other supplements in the matrix.
Piperine from black pepper can increase curcumin bioavailability dramatically (studies report up to ~20x).
