2.4. Randomization
Sixty selected subjects were randomly divided into two groups and supplemented with 3.7 g/day of flaxseed oil containing 2.2 g ALA (ALA group), or iso-calorie placebo (corn oil) (CONT group) containing 0.04g ALA for 12 weeks. The test sample allocation table was generated randomly, and study subjects were assigned. The study was blinded to both participants and researchers.
