Great VitC

This is one of the best quality vitamin C products I just discovered in iHerb! What's best about it is it has already vits D3 & zinc combined to it. This is my 2nd purchase (bought the biggest bottle) as the 1st one was a trial purchase.😅 The size of the capsule is a bit big but easy to swallow and accordingly, rapid dissolving. I presume the ingredients are great as it gives me & my family protection from common flu.

Repeat Purchase!

It has great quality ingredients. It boosts & protects the immune system but the size of the capsule is a bit big. I had pics already in my previous review of this.
