Corn/gmo free Vit C, professional brand
Wonderful professional grade product. No fillers or questionable inactive ingredients, and, most importantly, it is a corn free vitamin C derived to avoid gmo corn. Excellent high quality brand.

Excellent item , great price
Vitamin C is so important more now than ever. People are eating more fast food and less nourishing food and their health is suffering for it. I like to make up for my lacking eating habits by supplementing with Vitamin C. This particular brand is is quite a value compared to others.
