Young Group 4 Week ALA Treatment
Participants will receive the alpha-linolenic acid-rich supplement (ALA) (1000mg 4 times par day) for 4 weeks alpha-linolenic acid-rich supplement: each participant consumed one 1000 mg capsule of flaxseed oil four times per day for 4 weeks, providing a total of 2 g/d of ALA. The capsules used were a commercially available flaxseed oil supplement containing ALA at 56% of total fatty acids (Jamieson, Toronto, ON, Canada). The other main fatty acids present in flaxseed oil include linoleic acid (18%), oleic acid (16%), palmitic and stearic acid (10% combined).
