My wife and I like it because she is diabetic and it does not spike her sugar count like the drink does.

More than just acid
I definitely recommend this product over ascorbic acid. Bioavailability and absorption matter when it comes to vitamin supplements. Raw fruits and vegetables are the best, but if you need a boost in vitamin C, go with this.

The metabolites you would need in order to get anything out of the ascorbic acid would be in the food that you would have been eating anyway if you didn't need the supplement. This product is a true supplement.

Does this C contain calcium?
A shopper on May 18, 2019
BEST ANSWER: Yes, it has a small amount. If I remember correctly, this helps with any nausea, which I have never had with this product. It has bioflavonoids which are very good for you. I have used this brand for years, and I have always been completely satisfied with it. I have recommended it many times, including to my grown children.
