The effects of curcuminoids on lipids were not found to be dependent on the duration of supplementation .
Conclusion : This meta- analysis has shown that curcuminoid therapy significantly reduces plasma triglycerides and increases HDL-C levels
ABSTRACT Objective : The aim of this systematic review and meta- analysis was to determine and clarify the impact of curcuminoids on  serum lipid levels .
Curcumin effects on blood lipid profile in a 6-month human study.
Studies in animals and a short-term human study have suggested that curcumin , a polyphenolic compound concentrated in the curry spice turmeric , decreases serum cholesterol concentration . However , no controlled human trials have examined the effect of curcumin on cholesterol . This study investigated the effects of consuming curcumin on the  serum lipid profile in men and women . Elderly subjects ( n=36 ) consumed 4 g/d curcumin , 1g/d curcumin , or placebo in a 6-month , r and omized , double-blind trial . Plasma curcumin and its metabolites were measured at 1 month , and the serum lipid profile was measured at baseline , 1 month , and 6 months . The plasma curcumin concentration reached a mean of 490 nmol/L. The  curcumin concentration was greater after capsule than powder administration . Consumption of either dose of curcumin did not significantly affect triacylglycerols , or total , LDL , and HDL cholesterol over 1 month or 6 months . However , the concentrations of plasma curcumin and serum cholesterol were positively and significantly correlated . Curcumin consumption does not appear to have a significant effect on the serum lipid profile , unless the absorbed concentration of curcumin is considered , in which case curcumin may modestly increase cholesterol
