Rated 5 out of 5 by from Twin Labs Vit C Its challenging to write about this product without drawing a connection to my health. Without question, Twin Labs Vitamin C has kept me on my toes for decades now. It allows me to sustain a level of happiness and strength I could not achieve were it absent from my life. It is a wonderful product that I would recommend to anyone.

Rated 5 out of 5 by from Pure Vitamin C Doesn't come any purer than this. I trust the TwinLab brand and Swanson prices are unbeatable. I like these capsules because they can be opened up and the contents sprinkled on food, and because they're more convenient than unencapsulated powder form.
