I don’t really like to take Vitamin C because of the taste. These are not bad and easy to swallow. Going to put them on Autoship because I know I need to take them and like the price

These 500 mg vitamin C tablets were exactly what we were seeking. They were economical, and we feel as if they are of value in our vitamin regimen. The size is reasonable, and they are not difficult for us to swallow.
