In the treatment arm, subjects consumed 4.0 g/day borage seed oil and 7.0 g/day echium seed oil (containing totals of ~1.6 g/day of GLA and ~0.9 g/day of SDA). The oils were packaged in capsules each of which contained 1 gram of oil. Therefore subjects will ingest 10 capsules a day (3 in the morning, 3 in the afternoon, and 4 in the evening) with meals. In the placebo arm, subjects took matching capsules containing corn oil; three 1 gram capsules in the morning and afternoon, and four in the evening, with meals.
