Vitamin C

Vitamin C is the classic reach-for-it-when-you-feel-a-cold-coming supplement, though the evidence there is thinner than the marketing suggests. What it reliably does is cover a genuine nutrient need, and most people tolerate it well. High-strength and slow-release versions are popular; effervescent tablets are an easy way to take it if you dislike capsules.

Common questions

Does vitamin C stop colds?

Honestly, not really. The research suggests regular supplements might slightly shorten a cold but will not prevent one. Useful for covering a shortfall, not a magic shield.

Can I take too much?

Very high doses mainly give you an upset stomach, since the body flushes the excess. Sticking near the label dose is sensible; megadosing does not buy you more benefit.
