What Alyson mentioned were indeed true. That also shows she a smart consumer. Often we see alot of ppl buying or consuming supplement without really knowing the actual benefits. Mostly get to know through friends, families or the media.

Normal % of GLA in EPO is 9 to 10 % for every 500mg / 1000mg. For Seven Seas they claimed to have additonal 50% GLA extra which means 13.5% . As for Efamol they claimed to have 33% which is the highest.

for more benefits and studies on supplementation you can always check the net but mayoclinic.com is my prefered choice.
