You "feel" fish oil? Man you're lucky. I have a real good sense of how my body is doing (usually anyway) and I never feel supplements like this. I take them because they're good for you, but I always associated it with a long term thing, more along the lines of noticing if you stopped taking them. I've been using CLOmega for a few weeks, and like it. I like that I don't burp it up, so it's clearly easier on my stomach than whatever else I used to take (NOW fish oil, among others... had decent luck w/Carlsons, but burped lemon/orange flavor, lol). Right now I'm on 6 caps/day. Fish oil, green tea, vitamin C, garlic, these are all what I call my "longevity" supplements. I don't expect to feel or notice anything performance related from them, but I believe in the science behind taking them and that they can only help me reach my goals. MST is one of the only companies that has actually earned my trust (they better have, since they sponsor me, lol).
