evidence for vitamin c

Our honest take

An effervescent tablet sold as 1,000 mg of vitamin C that you dissolve in water. It is cheap and some people find a drink easier than a tablet, but 1,000 mg is about 25 times what UK adults need and much of it is not absorbed. Effervescent tablets often contain sodium and sweeteners, so check the label if you watch your salt intake. Fine as an occasional top-up; not something most people need every day.

You prefer a fizzy drink to swallowing tablets
You want a cheap, short-term vitamin C top-up
You have been told to limit salt (sodium): effervescent tablets can be high in it
You have had kidney stones or have iron overload (haemochromatosis): ask your GP first
You already eat plenty of fruit and vegetables: you are unlikely to notice a difference

The science

Vitamin C· evidence: Moderate

Vitamin C (ascorbic acid, or mineral ascorbates such as sodium, calcium or magnesium ascorbate) is an essential vitamin found in fruit and vegetables. Adults need about 40 mg a day in the UK, and most people who eat fruit and vegetables get enough. The body cannot store much, and absorption falls off at higher doses, so the extra from a 1,000 mg tablet is largely passed in urine.

The best evidence on colds (a Cochrane review) found that taking vitamin C every day does not stop most people catching colds, but may shorten them slightly. People doing very heavy physical exercise are the exception, where regular vitamin C roughly halved the number of colds in trials.

A supplement makes sense if your diet is low in fruit and vegetables, if you smoke, or around periods of hard training. Most people do not need mega-doses, and fancy forms (liposomal, ester or buffered) have little evidence of meaningful benefit over plain ascorbic acid, though buffered forms can be gentler on the stomach.

Authorised health claim
Vitamin C contributes to the normal function of the immune system. Vitamin C contributes to normal collagen formation for the normal function of skin. Vitamin C contributes to normal collagen formation for the normal function of cartilage. Vitamin C contributes to normal collagen formation for the normal function of bones. Vitamin C contributes to the reduction of tiredness and fatigue. Vitamin C contributes to the protection of cells from oxidative stress. Vitamin C increases iron absorption. (Applies where a daily dose gives at least 15% of the NRV, i.e. 12 mg.) Vitamin C contributes to maintain the normal function of the immune system during and after intense physical exercise (applies where the daily intake is 200 mg in addition to the recommended daily intake).

Typical dose: The UK reference intake for adults is 40 mg a day (NRV on labels: 80 mg). Supplements commonly give 200 to 1,000 mg.

Safety: The FSA advises that 1,000 mg (1 g) a day or less from supplements is unlikely to cause harm. Higher doses can cause stomach pain, diarrhoea and wind. People with a history of kidney stones, haemochromatosis (iron overload) or kidney disease should speak to their GP before taking high doses. Chewable and powder forms are acidic and can affect tooth enamel.
