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!

This vitamin C supplement was sent to me on time and in perfect condition, complete and sealed tablets. I like that they are 1000 MG per unit, so it is easier for me to have my daily supply complete and its antioxidant properties, it also prevents forgetting when taking it, the commitments are compact, easy to swallow, without notable odor or taste, the price is very affordable .
