Rated 4.8 out of 5 by 9 reviewers.
Rated 5 out of 5 by Good source of vitamin C I like this vitamin C powder. It mixes well in water. I mix it together with msm & magnesium in 2 qts. of water which I drink daily. Taste is not a problem. October 14, 2015
Rated 5 out of 5 by Best Vitamin C I've ussed I've used a number of different vitamin C products and this one is the best I've come across. It is cost-effective, easily dissolved, and does not cause acid-related difficulties. I use it every day and have for several years--would not be without it! May 26, 2013
Rated 5 out of 5 by 'Buffered vitamin C Vitamin C (ascorbic acid) has been proven to be of benefit in many areas of our health. This form of C is buffered so that it doesn't affect the pH of one's stomach. April 9, 2013
Rated 5 out of 5 by Many years ago my ND recommended vitamin C as calcium ascorbate in powdered form and I've been using it ever since. Now's product dissolves well in liquid with no bitter taste, as the calcium buffers the ascorbic acid. It's great added to flavored water. Now has a great product and Swanson's price can't be beat! March 30, 2013
Rated 5 out of 5 by Mixes well This dissolves better than most i have tried. September 19, 2012
Rated 5 out of 5 by Great Product I've got a sensitive stomach and GI tract, and this is a perfect way to get the extra vitamin C I need. I don't get any discomfort with this like I did other forms of vitamin C. July 28, 2012
Rated 3 out of 5 by It's Good enough Does the job More effective than Regular Vit C April 22, 2012
Rated 5 out of 5 by Calcium Ascorbate I can't take jus any type of Vitamin C. Calcium Ascorbate contains Vitamin C, but it doesn't have the negative effects of other Vitamin C brands. Excellent! July 1, 2011
