vitamin C powder

It is easy to take the amount you want. It is easy to use. The taste is real sour, so you want to drink it fast and then drink something else after ;-)

Best vitamin C on the market. I have tried many brands and this is the one I tolerate best.

Excellent product

Posted by Reviewer1795820 on Jun 10, 2012

Since I started taking it, I got addicted to it. It is so tasty, I definitely feel less pain in my joints but I also take many other products and antioxidants together, so it might be a synergistic effect.

No Sodium added/ Not sodium ascorbate: Most Pure Vit c around.

Posted by Reviewer2025236 on Jan 06, 2012

This vitamin c is best for me because it is pure with no binders or fillers and as I have many allergies , I have reacted to other vitamins. Purity is important to me. Individually, I prefer it because it is Not the sodium ascorbate.
