Super Primrose from NOW Foods:

A Vegetarian Fatty Acid That Imparts Important Health Benefits!

As one of the safest and most concentrated forms of GLA (gamma linoleic acid), evening primrose oil remains one of the most admired sources of essential fatty acids in today's market. Taken for centuries to promote natural health and healing, we now know that GLA encourages healthy cellular activity. Once ingested, GLA is converted into prostaglandins - natural metabolites with a strong influence on the normalization of our immune system inflammation response. Our super-high potency formula contains 1300mg of solvent-free primrose oil, delivering over three times the GLA content of regular primrose oil.
