Have not gotten a cold or anything else sense I have been taking this product. That is over four years!
Product was excellent. Deliver was very good.
I am a firm believer in the benefits of vitamin C. A nutritionist introduced me to Perque Potent C. It works very well for my overall health.
I have been using Perque Potent C Guard for years because of its buffering feature and complimenting minerals and Supliment First is a great source.
This is the best vitamin c on the market!! Easy to use and such a remarkable product. Package delivered promptly with all the other perque products. Love Perque Potent C Guard
