Review: 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.
Review: Good product - Bought another bottle halfway through the first one because it is good and cheaper than other brands.
