Rated 5 out of 5 by from best deal you can find on a basic Vitamin only recommended form of Vit C, and this is the cheapest way to get it!

Rated 1 out of 5 by from Really hurt my digestive system I would recommend anyone with a sensitive digestive system stay away from these tablets. They were so much harder on me than the capsules. I tried many different things to improve it but there's no way around it. I'm returning the tablets for a refund and re-ordering the capsules.

Rated 5 out of 5 by from Exudes Confidence I feel confident in this supplement with so many germs everywhere today. Also, like the price and quality of Swanson products. Getting it online is a big plus since I am a senior citizen and am not fond of running around to stores.

Rated 4 out of 5 by from Great product I take vitamin C for a variety of reasons but this vitamin C is one of the easiest C's to take that I have found. I've had great success taking this vitamin C without the usual reactions to C that I get from other brands. Great product.

Rated 5 out of 5 by from must have I love this product. It smells great, easy to swallow, and it doesn't bother my sensitive stomach. It helps immunity a lot. Thanks.

Rated 5 out of 5 by from Buffered C gets an A+ I subscribe to three different medical newsletters all of which have recommended vitamin C. Some brands are not all that friendly to your stomach. This one is buffered so it can be taken on an empty stomach to be the most effective. It's the first thing that enters my mouth each morning! The bioflavonoids are a bonus!

Rated 5 out of 5 by from very good value We found buffered vitamin C at Swanson's about 3 years ago. We always had trouble finding it locally and never at a good price. This is the best quality and price anywhere. Will never have to worry about vitamin C quality and convenience again.

Rated 5 out of 5 by from Glad Glad I switched from what I was buying, I feel I am getting comparable effectiveness and a much better price! Thank you Swanson.

Rated 5 out of 5 by from I'm a fan I am a daily user of vitamin C for several reasons. The main one is for my immune system. I would say this is a quality product because my immune system is very strong, whereas before using Swanson Vitamin C, that statement was not true. I really like this particular variety because it contains bioflavonoids and some calcium as a buffer. This product does not upset my stomach--I take 4000 mg daily.

Rated 5 out of 5 by from Great Product I have been taking Vit C for quite a few years. This is the first time I've come across "buffered" Vit C. I like the fact that it has Bioflavonoids. There is no bitter taste as with regular Vit C. I would recommend this product to anyone who wants Vit C protection, plus extra protection from the bioflavonoids.

Rated 5 out of 5 by from best price per gram of buffered C my doctor had be switch to buffered C for ph balance. I searched high and low and Swanson came out way ahead in value.
Date published: 2012-03-26
Rated 5 out of 5 by from Best Vitamin C on the market. I like how it does not have soy or silica products in the ingredients. Boost your immune system. Doesn’t cause bloating or stomach discomfort. I only wish it was less expensive.

Rated 5 out of 5 by from Great deal I've paid double for half the amount with another product at a chain store. So glad I found Swansons.

Rated 5 out of 5 by from Just what my Stomach ask for! Everyone's aware of Vit C's usefulness but it can also be hard on the stomach thus I've avoided appropriate doses. However Swanson Buffered C hasn't let me down yet and I now benifit with C's protection.

Rated 5 out of 5 by from Works as it Should Provides advertised levels of buffered vitamin C at a very good price. The buffering is sufficient enough that I do not experience any upset stomach, even when taking several tablets at a time.
