Studies
These studies provide scientific insights into DHA benefits:
A 2013 randomized trial in 50 overweight women with metabolic syndrome showed 2 g/day DHA for 12 weeks improved insulin sensitivity by 15% versus 3% with placebo (P = 0.02) and reduced hepatic fat content.
A 2012 double-blind RCT in 40 type 2 diabetics found 1 g/day EPA+DHA for 6 weeks lowered CRP by 18% versus 4% with placebo (P < 0.01) without affecting glycemic control.
