Now is my favorite brand!

I'm new to this product but I have heard great things about it. Especially in winter months, I try to help my respiratory system by giving it a boost. The capsules are large but I have no difficulties swallowing them myself ... others that have a hard time with large pills may have a harder time. I really like the fact this has zinc as another ingredient.

I love the NOW Brand Supplements and Vitamins. They are easily digestible and don't irritate my stomach. I've been taking them for several years. I like when they combine a couple of the vitamins and minerals together like with this NAC, Quercentin and Zinc.

All-in-1 Zinc, Quercetin, and NAC!

I was purchasing these three products separately until I found this one that has the same amounts all in 1 capsule. Much more efficient and a perfect anti-viral supplement that's easy to take.
