Vitamin C

Vitamin C is a water-soluble antioxidant, essential for the formation of collagen (skin, blood vessels, gums), immunity and the absorption of iron from plants. The body does not store it, so it needs it regularly from food.

Why it matters

EFSA: deficiency with a poor diet.

If it’s low

Low vitamin C can cause fatigue, bleeding gums, poorer healing; extreme deficiency is scurvy.

If it’s high

High vitamin C from food is not harmful; the excess is excreted. Very high supplements can, in those predisposed, raise the risk of kidney stones.

What to do

For maintenance, regular fruit and vegetables are enough (citrus, peppers, berries). With low iron, eat it together with iron for better absorption.

When to see a doctor

Bleeding gums, poor healing (possible deficiency)
