What is Vitamin C?
Vitamin C is a water-soluble vitamin that the human body, unlike most mammals, cannot synthesize. It functions as a powerful antioxidant, a cofactor for collagen synthesis (essential for skin, blood vessels, and connective tissue), and a key player in immune defense. Buffered vitamin C is paired with minerals like calcium, magnesium, or potassium, raising the pH and making it gentler on the stomach than ascorbic acid alone, particularly important at higher doses. While the 90 mg daily reference intake prevents scurvy, optimal intake for general health is debated but often cited as 500-1,000 mg per day. Doses above 2 g can cause loose stools.
