The human body cannot produce it itself and is entirely dependent on food. Vitamin C acts as an antioxidant and as a cofactor in collagen synthesis, iron absorption, and immune function.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eMost mammals produce their own vitamin C in their liver via the enzyme L-gulonolactone oxidase. Humans, primates, guinea pigs, and a few other exceptions lack this enzyme due to a mutation in evolutionary history. As a result, we are entirely dependent on external supply. A deficiency classically manifests as scurvy — a disease that historically afflicted sailors during long voyages without fresh fruit.\u003c\/p\u003e\n\n\u003cp\u003eIn common foods, bell peppers, broccoli, citrus fruits, kiwi, strawberries, and rose hips are good sources. Tropical sources stand out numerically: Camu Camu from the Amazon contains 30-60 times more vitamin C per gram than an orange, and acerola is similarly rich. Both are used as the basis for \"natural\" vitamin C supplements.\u003c\/p\u003e\n\n\u003cp\u003eVitamin C is sensitive to heat, light, and oxygen — a large part disappears during cooking, storage, or prolonged exposure to air.

The body cannot produce it itself. Vitamin C acts as an antioxidant and as a cofactor in collagen synthesis, iron absorption, and immune function.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much Vitamin C per day?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe European RI is 80 mg per day.
