Barleans user, here. They're spoda be real clean about toxins. Hell, they've even submitted to testing by the International Fish Oil Standards Program.
Yeah, sounds like utter bullschidt, but
here it is. I've never had a fish oil burp with any product, ever, so I don't know about those.
I hate taking pills, in general, but these aint bad, I don't have to take too many, or too often, and they make both the wife & the Dr. happy. If the fish pills allow me to be around long enough to return aggravation to my children, I'm all for 'em!
As a teenager, I remember my dad chuckling at how many pills his FIL had to take each day. Now Dad takes as many, if not more, than his FIL ever did. As for me, I'm willing to take a few non-Rx pills, if they'll keep me from needing many fistfuls of the the Rx kind.
