Rated 5 out of 5 by from Easy to swallow capsules This is an easy to swallow capsule. The milligrams are not too great but have added bioflavonoids which makes it an even better value.

Rated 5 out of 5 by from Easy on tummy The acid in regular C bothers my stomach. This does not and at a great price compared to retailers and other online stores.

Rated 5 out of 5 by from Good value Good value. I once got some straight ascorbic acid, and quickly saw a deficiency - we need the buffered stuff.

Rated 4 out of 5 by from Ok product but... I found this buffered vitamin C to be very cost effective. The only issue (and it could just might be My problem) is it could use a little more buffer to it. I have a very slight burning sensation in my gut after taking one. A lot less mind you the regular C but still compared to other major brands I have bought at the health food store it still has more bite to it. Overall though a good product.

Rated 5 out of 5 by from Excellent! I love that this buffered C is in capsules. It is easy on digestion, and it is an added plus that it is fortified with bioflavonoids. It's my favorite way to take vitamin C.

Rated 5 out of 5 by from always good to take buffered C This is a very reasonable source. Ascorbic ACID by itself can cause stomach problems. My Dad had this and when i switched to this, the problems disappeared.

Rated 5 out of 5 by from Great for people who have issues This is a great product. The thing I most appreciate about it is that I can get my vitamin C with no stomach problems. I have a sensitive stomach system and these are great. No problems at all.

Rated 1 out of 5 by from Too much filler This product has a lot of fillers. I am not sure how much actual vitamin C it has.

Rated 5 out of 5 by from A Must Have My husband and I both take this Vitamin C and have great results from it. Years ago there was a more expensive, name-brand we would buy from Swanson. But it became unavailable so we switched to this and have been extremely satisfied. It is a "staple" in our home. Thank you Swanson for the affordable price.

Rated 5 out of 5 by from As good as Ester C As an older adult, some vitamins cause digestive upset. I like this product.

Rated 5 out of 5 by from Vitamin C buffered This is a staple in my daily vitamin's and as it is buffered which I need it is a huge plus.
Date published: 2013-04-29
Rated 5 out of 5 by from Excellent Product Excellent product. Will purchase again. Would like to see this product in a 1,000 mg. capsule. It currently is sold only in tablet form for the 1,000 mg. strength.
Date published: 2013-03-24
Rated 5 out of 5 by from Love this product I love this buffered C. It never causes stomach upset, like other brands that are not buffered. The capsule is a little too big for me, so I just open up 2 capsules, add to some applesauce. I won't take any other vit C. The price is great too. Thanks Swanson!

Rated 5 out of 5 by from a great vitamin C My Husband and I have been taking this buffered C with bioflavonoids for quite a few years and really like it - get your vitamin C and flavonoids together! Since we each take them twice daily, this bottle of 100 caps only lasts 25 days. I wish that Swanson would offer it in a larger size = perhaps 250 in a bottle.
Date published: 2013-01-26
Rated 5 out of 5 by from Highly Recommend! The first vitamin C supplement I've been able to take without suffering from severe acid reflux, heartburn and indigestion. Good stuff!
