Rated 5 out of 5 by from Friendly C I ordered this C recently without realizing it came in the form of tablets. I had been ordering the capsules - which are easier to swallow. Still, the tablets are coated and go down easily. This buffered form is great as it doesn't cause me an upset stomach like other regular C's do. I take 1,000 mg. each after lunch and dinner. Highly recommend.

Rated 5 out of 5 by from Swanson Buffered C My husband and I both use this product. It's very well-tolerated by us, and we feel it lends a help to our immune system. There's no acidy feeling after taking it, which is a real plus.

Rated 5 out of 5 by from Best Vitamin C I have found so far I recently started using the buffered C. I did not know the difference before and my diet coach got me on the buffered. It did help as I was shedding my last 10 pounds. I take it prior to cardio workouts and on a non-workout day, morning and evening. I tried one of the other buffered Cs, but it upset my stomach, so I am sticking with this one, it is great and you can't beat the price!

Rated 1 out of 5 by from Not a good value This tablet passes whole into your stool. Even breaking them in half did no good. I have never had this happen before. I will not be buying this one again!
