“I've given 4 stars, rather than 5 only because I always feel it's difficult to assess Vitamins. I can't really determine their efficacy without medical testing. However, I assume they're doing their job, but can't actually confirm I feel different. I was medically recommended to take a daily supplement of Vitamin D. The JustVitamins price for larger quantity is comparatively good, their product information and website is easy to use and their ordering and supply efficient and fast.”
