insightsAnalysis

This product offers 500mg of Vitamin C in the buffered form of Calcium Ascorbate, which is often preferred by individuals with sensitive stomachs as it's less acidic than standard Ascorbic Acid. It also includes a small amount of calcium and a Citrus Bioflavonoid Complex, which can enhance the overall benefits.

With a very attractive price per serving and an impressive number of positive reviews, this NOW product delivers excellent value and reliability. It's a fantastic option for daily Vitamin C intake that is gentle on the digestive system.
