If the acid from typical vitamin C supplements irritates your stomach, our Buffered Sodium Ascorbate Vitamin C Powder is a gentler way to get your daily allowance or more. Using only vitamin C from sodium ascorbate, our Buffered Sodium Ascorbate Vitamin C powder is highly soluble and gently buffered to neutralize acidity. Vitamin C is an essential nutrient that cannot be produced by the body and must be replenished daily. Vitamin C helps support the immune system by protecting the body from oxidative stress.* Supplement your need for C by mixing our easy-blending powder with your favorite beverage. Just one scoop daily is all you need.

Customer Ratings & Reviews

Buffered Sodium Ascorbate Vitamin C Powder is rated 4.4 out of 5 by 18.
Rated 5 out of 5 by from Great supplement! I love the purity, simplicity, and ease of this vitamin c powder. It allows me to get higher doses of vitamin c without any other additives or fillers.

Rated 4 out of 5 by from On the fence with this one. I purchased this based on some research online for an effective form of vitamin c that was easier for the body to absorb and was easy on the digestive tract as well. But wait, then I researched any potential side-effects. I cannot list them here, as that would be a medical/disease claim, which posting here is against governmental regulations. They were enough to make me thin twice about this one. I may stick to other forms. Aside from that, you get 60 doses for a fair price. If this product still interests you because of its ease on the digestive tract; I would strongly suggest researching this supplement; and if needed, also speak to a healthcare practitioner.

Rated 5 out of 5 by from Easy to Use I use the buffered vitamin C powder twice weekly to boost my intake of vitamin C. This product is easy to use and measure. It is buffered, so gentler to my system.

Rated 5 out of 5 by from Very Versatile! This is great stuff and I love being able to add it to puddings, smoothies, dips, or anything else I'm making when I need a little extra Vit. C in my diet.

Rated 1 out of 5 by from Awful Loaded with salt, and it tastes like it too. Don't waste your money on this turkey. Get the Carlson.

Rated 5 out of 5 by from Powdered Vit C I've been taking Vitamin C tablets/capsules for over 20 years. Then I discovered this product several years ago and began using it instead of the capsules. It is much cheaper and easier to use as I simply sprinkle it on my cereal in the morning and hardly taste it at all. When I do taste it, it tastes like a tart fruit. If you are a constant Vitamin C user like me, this is the only way to go.

Rated 5 out of 5 by from Awesome Product! This was exactly what I was looking for to help boost my immune system. It is easy on the stomach and can be mixed in smoothies to boost my vitamin C intake.

Rated 5 out of 5 by from Great product This is an amazing product, I can get Vitamin C into my system without having to deal with the heartburn that standard Vitamin C gives me.

Rated 5 out of 5 by from Best VitC option I can't take Vitamin C capsules due to the acidity, which is unsettling in my stomach. I began using this in my morning juicing as a way to get Vit C in my system and it is convenient and works well.

Rated 5 out of 5 by from Singing Canary I used this for the singing canary health drink from Trim Healthy Mama. I've only used it once, but so far so good.

Rated 5 out of 5 by from Happy With This Vitamin C I am happy with this Vitamin C product. It is one of several that I use. I use this when I need some higher doses; but I also try to stick with some more whole food Vitamin C products, such as rose hip powder. I believe using a mix of various Vitamin C products will give our bodies a broader range of Vitamin C support. Shalom.

Rated 5 out of 5 by from Added benefits So I've taken a lot of vitamin C in my time but this is now my preferred way of taking C. I can take as much C as I need without having to worry about the after effects!! I love the dosage, you get a lot for the money!!

Rated 5 out of 5 by from Exactly What I Was Looking For I purchased this item because I was making my own sodium ascorbate and it was inconvenient. (vitamin C powder + baking soda) This pre-mixed powder is much more convenient to use, mixes well in liquid, and I seem to be receiving the same benefits that I did with the home made. I will purchase this item again, and would recommend it for anyone who is using high dose vitamin C supplements.

Rated 4 out of 5 by from Recommended to me As the most "absorb-able" form of Vitamin C. I use this in homemade baby formula and it doesn't curdle the milk. I use just a small amount for the batch I make.
