The yellow pigment that gives turmeric its color, curcumin has been shown by numerous previous studies to exert antioxidant and anti-inflammation effects. David S. Rowlands, from Massey University (New Zealand), and colleagues enrolled 17 men in a study in which each subject received either 5 grams curcumin daily, or placebo, for 2 days before and 3 days after performance tests. This was followed by a 2-week ‘washout’ period, after which the subjects crossed over to the other intervention. Moderate-large reductions in pain during exercises, as well as small increases in performance, were achieved in 1-2 days among the curcumin group. The study authors report that:  “Oral curcumin likely reduces pain associated with [delayed onset muscle soreness] with some evidence for enhanced recovery of muscle performance.”
