5 out of 5 stars
I'm 62 and for the last several years I've noticed that every time I got a cold it would hit me harder and last longer than it used to. My wife kept telling me I needed to do something about it. I looked into a bunch of different immune supplements and settled on Heptamune because of the NAC and the quercetin on top of the basics like vitamin C and zinc. I've been taking it daily and I honestly feel like my body is just better prepared now. I had one minor sniffle that lasted maybe a day and a half. That's it. Very pleased with this purchase.
