Cheap but Quality Vitamins
This is my go-to vitamin C. Aside from it being super affordable, I can't say anything much about it. I can't tell if I'm being protected in some way but I also combine it with Zinc, Vitamin D and Biotin. This always comes in a bubble wrap which is a plus and so far no bad side-effects.

My favorite brand of Vitamin C now!
After trying a number of brands of Vitamin C, I’d say this is my most favorite. The prolonged release is perfect for people with hyperacidity like me. Overall I’m so happy with my purchase! And I got it on sale too, it’s really so worth it!
