^#Samples 1–10 are collected from healthy Finnish women (W) and men (M) having their habitual diet and samples, 11–20 are from the same individuals after 8 days of flaxseed supplementation (25 grams per day). Samples with ED levels below the limit of quantification are marked nq (non quantifiable).
