Curcumin

Evidence ratingModerate

The yellow polyphenol pigment of turmeric. Meta-analyses of RCTs report reduced post-exercise inflammatory markers (CRP, IL-6, TNF-α) and less delayed-onset muscle soreness (DOMS), via suppression of the NF-κB pathway. Plain curcumin has very low bioavailability (~1%), which piperine (black pepper) is reported to raise about 20-fold.

Effects reported in research

Reported reductions in post-exercise inflammatory markers (CRP, IL-6, TNF-α)

Reduced DOMS at 24–48 hours post-exercise shown in meta-analyses (moderate effect size)

Dosage & timing

Studies use standardized extracts (~95% curcumin).
Because absorption is poor, formulations with piperine or liposomal delivery are preferable.
Turmeric powder is only 3–5% curcumin, so it rarely reaches the doses used in studies.

Cautions

•High doses can cause digestive upset (stomach discomfort, diarrhea).
•People with gallstones/bile-duct obstruction or on anticoagulants should consult a doctor, as it may affect bleeding tendency.
•It is not a substitute for adequate recovery, nutrition, and sleep.

Meta-analysis

Meta-analysis of curcumin supplementation on exercise-induced inflammation and delayed onset muscle soreness (DOMS)

Asian Journal of Sports Medicine, 2015

A meta-analysis of RCTs examining the effects of curcumin supplementation on post-exercise inflammatory markers (CRP, IL-6, TNF-α) and muscle soreness (DOMS). Curcumin significantly reduced inflammatory cytokines by inhibiting the NF-κB pathway and significantly reduced muscle soreness scores at 24–48 hours post-exercise. However, the bioavailability of curcumin alone is very low (~1%), and co-administration with piperine (black pepper component) is known to increase absorption approximately 20-fold.
