For skin health, hormonal balance, and inflammation support, the key nutrient you're getting from **Evening Primrose Oil** is GLA (gamma-linolenic acid). Each softgel delivers 117mg of GLA from 1,300mg of evening primrose oil. Clinical studies typically used 240–320mg of GLA daily, so you'd need 2–3 softgels per day to reach that range — which aligns with the label's suggestion of up to three daily.
At the full three-softgel dose, you're getting about 351mg of GLA, putting you right at the upper end of what research has studied. That's the dose where you're most likely to see results for your skin or hormonal goals.
One thing to keep in mind: the directions say "up to three times daily," but a single softgel only delivers about half the minimum clinical GLA dose. If you take just one, you're getting less than what studies showed was effective.
