I'm still not sure this acid free product is necessary. I bought it for my dog who has hip dysplasia. I think he likes the colorful packaging.

I prefer Vitamin C capsules to tablets, and this is a good and affordable version.

This works more efficiently than the regular absorbic acid. I take about 3 a day and rarely, if ever, get sick.
