My wife takes this all the time for several years and she finds it good. Good price.
I found this to be excellent product worked really well but after reading the peel back label I realized that I shouldn't take if prone to kidney stones so I discontinued use.

Vitamin C though one of the more common vitamins can still be confusing to buy. To increase profits many companies prepackage and add sugar and dye to vitamin c crystals. We love Natural Factors Vitamin C Crystals because they only contain Vitamin C! And being able to buy in bulk gives us no excuse to not be a healthy family. For a cold, try having it with warm water and local honey to help you sleep and feel better in the morning. As far as Natural Factors, they are a great Canadian company with clean ingredients and very reasonable prices.
