Vitamin C: immunity and beyond
2026-06-27 · 4 min read
Vitamin C is a powerful antioxidant the body does not store, so you need it regularly. It is known for immune support, but its role is broader — from blood vessels to collagen synthesis.
Why you need it
Vitamin C supports immunity, protects cells from oxidative stress, is needed for collagen synthesis (skin, vessels, joints) and helps absorb iron from plant foods.
How much and which form
The baseline need is small, but under load and in cold season many take 500–1000 mg per day. Buffered forms are gentler on the stomach; large doses are better split through the day.
When to take it
Vitamin C is water-soluble, so it is convenient with food through the day. Very large single doses can upset the stomach — increase gradually.
FAQ
Does vitamin C prevent colds?
It does not fully prevent them, but regular intake may slightly ease and shorten a cold, especially under physical load.
Can I take vitamin C every day?
Yes, at a sensible dose it is safe. Excess is excreted in urine, but very large doses are best avoided without reason.
