Studies
These studies provide scientific insights into Flax Seed benefits:
A 2005 randomized, controlled trial in 35 hypercholesterolemic adults found 30 g/day milled flaxseed for 4 weeks reduced LDL-C by 10 % versus 0 % with control and lowered systolic blood pressure by 5 mmHg.
A 2013 crossover RCT in 40 type 2 diabetics showed 13 g/day flaxseed for 12 weeks decreased HbA1c by 0.3 % versus 0.0 % with placebo .
Despite alpha-linolenic acid content, no RCTs have assessed flaxseed oil capsules for inflammatory biomarkers in humans.
