The Evening Primrose Oil in this product is extracted without Hexane or other chemical solvents. It uses only the cold process, "expeller-press" method of extraction, which is simply squeezing the oil out of the seed without heat.

Twinlab Mega Primrose Oil 1300 is the highest quality Evening Primrose Oil softgel available. It is more than twice the potency of many other brands which contain only 500 mg. Because it is more potent, one or two softgels a day are all you need.
