"Have been using this vitamin C for years and couldn't be happier with the supplement. Easy on the stomach and very absorbable." ~product review by Neptune

  • Take higher doses of C without stomach irritation

  • Gently buffered to neutralize acidity

  • Bioflavonoids enhance antioxidant properties

For a powerful boost of antioxidant protection that won't upset your stomach, Swanson Buffered C with Bioflavonoids is an excellent choice. It features a unique form of vitamin C that's bonded to calcium through a special process that neutralizes the vitamin's acidity, making it gentler on the stomach--but that's not all. Each capsule also includes 200 mg of natural citrus bioflavonoids that promote efficient assimilation of vitamin C and enhance its antioxidant potency.

vitamin c Easy to swallow vitamin C are easier on my stomach than some other forms, and easier to swallow. March 3, 2014
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. January 15, 2014
Great value Vit C This buffered C is a great price, and is gentle on the stomach. December 18, 2013
Love it! I've been using this particular vitamin c for years now. We love it. November 22, 2013
best yet best value from a reputable company November 15, 2013
Perfect Have been using this vitamin C for years and couldn't be happier with the supplement. Easy on the stomach and very absorbable. September 16, 2013
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. August 12, 2013
Too much filler This product has a lot of fillers. I am not sure how much actual vitamin C it has. July 29, 2013
Perfect I would recommend this to anyone. It has always been the perfect supplement. July 15, 2013
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. June 12, 2013
As good as Ester C As an older adult, some vitamins cause digestive upset. I like this product. May 28, 2013
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. April 29, 2013
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. March 23, 2013
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! March 22, 2013
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. January 26, 2013
Highly Recommend! The first vitamin C supplement I've been able to take without suffering from severe acid reflux, heartburn and indigestion. Good stuff! January 15, 2013
I used this regularly in part because it had no magnesium stearate. But recently they put magnesium stearate in it, which causes me leg cramps at night. I did not know they had put magnesium stearate in it but I started having cramps and checked al my supplements and there it was. Quit this and my leg cramps quit. Found other sources of C with no stearates. Swanson had a study done that showed Magnesium sterates causes no harm. I see lots of such studies that later are not correct. I love Swanson except for the fact that they are putting stearates into many supplements that previously had none July 27, 2012
Excellent! I love the price of this great quality product. I've purchased this many times and am pleased to buy again and again. Does not upset my stomach. March 30, 2012
Swanson Premium Buffered C w/ Bioflavonoids Qualified product at competitive price. My biochemical metabolism tells me that this is qualified one. December 10, 2011
A better C This vitamin C does not hurt my stomach because it's buffered. I take 2,000 mg. per day. I like the fact it comes in capsules as opposed to tabs. Great product at a great price. November 14, 2011
Buffered C w/Bioflavonoids Great product for the price. Great for digestability and not hard to swallow for its large size. I have been using this for years and recommend it. September 28, 2011
Good Choice This product is a very good value. It does not leave you with the vitamin burps and can be taken without food but I always take with a full glass of water. It is part of the daily routine in our family and we are all very healthy. Would highly recommend it. June 5, 2011
Easy on the tummy! I love this product because I get my vitamin C without the acidic stomach! February 9, 2011
Great C This is a very nice combo of vitamin C and bioflavonoids at a price you can't beat. Great value!! November 25, 2010
great buffered product I can't take regular Vit. C so this is a good alternative. It doesn't bother my stomach or give my cankers like regular vitamin C-not even after my gastric bypass 3 months ago! September 16, 2010
