MASON NATURAL Evening Primrose Oil 1000 mg

Our verdict

MASON NATURAL Evening Primrose Oil 1000 mg works out to $0.11 per serving of evening primrose oil, at 1000mg per serving in softgel form. That puts it the cheapest quarter of the 20 evening primrose oil products we can price per dose, where the typical serving costs $0.18, a Value Index of 1.6 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $3.40 a month. We could not verify a third-party certification for MASON NATURAL in a public registry.
