This standout vitamin C powder is ideal for those who need high-dose vitamin C but have a sensitive stomach. While high amounts of vitamin C are essential for immune support and overall health, they can be tough on digestion. Thorne solves this by adding buffering minerals like calcium, magnesium, and potassium, which neutralise acidity and make it easy on the stomach. This means you can comfortably take higher doses and get the full benefits of vitamin C, boosting your immune system, protecting against oxidative stress, and supporting overall wellness, without any discomfort.
