I take a 22mg dose...plus what I eat. Just cover the bases..lolNice discussion going on in here. Late to this thread today, but would add that my own digging around about the bioavailability of zinc supplements brought me to a few published studies that showed the bioavailability is about 60%. That would make one reason that if you were taking in 50 mg, you are absorbing 30 mg (not counting dietary sources).
That is what I take. Too much? I don't know. But I do take 2 mg GHK-Cu daily.
