Vitamin C is a water-soluble vitamin and powerful antioxidant essential for collagen synthesis, wound healing, iron absorption, and immune function. Severe deficiency causes scurvy, while mild deficiency can cause fatigue, poor wound healing, and weakened immunity. Smokers, those with limited fruit and vegetable intake, and people with certain GI conditions are at higher risk for deficiency.
