abstract
Curcuminoids have potentially important functional qualities including anti-inflammatory and antioxidant properties. In this randomized double-blind placebo-controlled cross-over trial, the effects of a curcuminoid supplement on serum pro-oxidant-antioxidant balance (PAB) and antibody titres to Hsp27 (anti-Hsp27) and oxLDL (anti-oxLDL) were investigated. Thirty obese individuals were randomized to receive either curcuminoids (1 g/day) or placebo for a period of 30 days. After a wash-out period of 2 weeks, subjects were crossed over to the alternate regimen for another 30 days. Serum PAB along with anti-Hsp27 and anti-oxLDL titres was measured at the beginning and at the end of each study period. There was no significant carry-over effect for any of the assessed parameters. Curcuminoid supplementation was associated with a significant decrease in PAB (p = 0.044). However, no significant change was observed in serum concentrations of anti-Hsp27 or anti-oxLDL (p > 0.05). These findings suggest that oral curcuminoids supplementation (1g/day) is effective in reducing oxidative stress burden, though this needs to be validated in larger study populations.
