I'd like to buy some lecithin (those without mixed with animal-derived ingredients). Which nutrition manufacturers are famous or reasonably good ?I am ignorant on US' nutrition manufacturers. I just know GNC is good but too expensive. How about NOWFoods ? Their prices are good. AS I may buy quite a lot but I also want the quality to be reasonably good (though not need to be exteremly good) with affordable prices. Any previous experiences maybe helpful. Thanks!
