Antioxidant & Collagen Support Dietary Supplement Gluten Free Made With Non-GMO Ingredients Not Tested on Animals™ NitroPak® Naturally Fresh, Bacteria Free Environment pH 6.8‡ Rapid Dissolving NutriBiotic® Buffered Vitamin C capsules deliver 100% pharmaceutical grade vitamin C (L-ascorbic acid) in combination with an array of highly bioavailable minerals, including calcium, magnesium, potassium, and zinc (which are mined from the earth) to form mineral ascorbates. Ascorbates are buffered and, therefore, less acidic than pure vitamin C. Vitamin C, calcium, magnesium, potassium, and zinc are essential nutrients that help support the body. Vitamin C provides antioxidant protection to the immune system, as well as maintains the health of blood vessels, tissue, cartilage, bones, eyes, and other organ systems. Vitamin C is also required for the biosynthesis of collagen, L-carnitine, and neurotransmitters. The other nutrients in Buffered Vitamin C help maintain bone and immune health and regulate fluid balance, muscle contractions, and nerve signals. The positive effects of the combined nutrients make them vital to the body's overall health. These capsules provide vitamin C and minerals in a pure, pre-measured form. These potent, water-soluble nutrients are encapsulated to be convenient, easy-to-swallow, and rapidly dissolving. Our promise and guarantee: We use only 100% pure pharmaceutical grade L-ascorbic acid USP-FCC† (C 6 H 8 O 6 ), which contains no corn residue, plant antigens, or protein impurities. †United States Pharmacopoeia - Food Chemical Codex. ‡Measure of Acidity/Alkalinity (neutral pH is 7.0).

Buffered vitamin C

Buffered vitamin C is better for those with sensitive digestion or compromised gastrointestinal function. In buffered vitamin C supplements, the vitamin C is "buffered" with minerals, reducing the acidity and improving tolerance. Comes in capsules which is easy to swallow.

The Best

Bought this for our daughter who is a college athlete and was getting to that two week acclimation point of starting back to college where everyone is getting worn down and the sniffles and she said this really helped her get past the yucky and keep going. She feels great and has recommended to many of her friends.

Nice size

It is a fairly large container that is suited for having a stock at home to last you a longer period of time. Althought the pill is larger than usual, it is okay to swallow for me. Have not noticed any quality drops. Ingredients seem to be ok. Product does the job.

Gentle Vit C

This NutriBiotic Buffered Vitamin C is an excellent choice for anyone seeking immune and collagen support without the digestive issues tied to traditional ascorbic acid supplements. Because the formula is buffered with minerals like calcium and magnesium, it is incredibly gentle on sensitive stomachs and causes zero acid reflux, even when taken on an empty stomach. The standard-sized capsules are completely tasteless and easy to swallow, bypassing the sharp, sour tang of chewable alternatives. The product arrived fully sealed and intact, housed in a sturdy plastic bottle with a highly convenient flip-top lid that allows for easy, one-handed dispensing. Overall, it is a well-packaged, highly effective supplement that delivers all the antioxidant benefits of Vitamin C with absolutely none of the stomach irritation.

Vitamin C — simple but reliable support

Started using vitamin C consistently and it’s one of those supplements that quietly makes a difference. It’s not dramatic, but over time I noticed better overall resilience — especially with immunity and recovery. What I noticed: • slightly reduced allergy sensitivity • better recovery and less fatigue • skin looks a bit brighter over time It feels more like foundational support than something you “feel” strongly. Key takeaway: • supports immune function and antioxidant balance • mild but consistent benefits • easy to include daily Simple supplement, but very dependable as part of a routine.

Buffered Vitamin C

It’s a good product. The size of the capsule is fine. I appreciate that it doesn’t have gluten in it and because it’s buffered it doesn’t upset my stomach. The price was also appealing.
