Fish oil contains omega-3's, it's very good for your heart! If any of you take fish oil and you end up burping it up and tasting it (so sick), then it's synthetic and your body does not recognize it because ANYTHING synthetic the body recognizes as a "poison", period. ALL vitamins you buy at GNC or ANY other vitamin store, they are ALL synthetic that's why if you are take them on an empty stomach and they give you a sick uneasy feeling in your stomach, they are NOT natural. That's crazy, huh? BELIEVE IT or NOT.
Yes, very true, if the company finds it cheaper to produce synthetic look alikes, they will! They don't seem to think of us. Another thing to watch out for is that because they are supplements, they do not follow similar guidelines as with food. By that I mean that what's in the pot doesn't have to be put on the label and what's on the label doesn't have to be put on the pot. If they are made to pharmeceutical grade, (which is very costly and why some supplements are pricier than others) then you can trust the label. HTH
