I READ THE RESEARCH, SO YOU DON'T HAVE TO ™

This is a good product for boosting immunity without upsetting the stomach. Use throughout the day to keep blood levels high. Also great for collagen production. Good stuff.

This vitamin c is easy to take with a glass of water, I take a double dose in the morning rather than 3x daily. It works great, the ingredients are good.

Good Vitamin C powder

Have been taking Kirkman Labs, Buffered Vitamin C Powder to boost my immunity due to antioxidant qualities of Vitamin C. Happy with the quality, it doesn't irritate my stomach or raise stomach acidity. The package is fine, need to use your own measuring spoon. Happy that it is unflavoured!

Great

My doctor prescribed it to me and I’m sure it’s of a high quality just mixing it with water and it yoy travel - then it becomes inconvenient to portion it. Other than that it’s great
