evidence for vitamin b12

Our honest take

Vegan chewable methylcobalamin tablets in four strengths: 500, 1,000, 2,500 or 5,000 µg per tablet, as named on each option. For vegans and older adults, the 500 or 1,000 µg tablets are plenty and the cheapest per tablet; the higher strengths cost more and are not needed unless a health professional suggests them. Methylcobalamin has not been shown to work better than standard cyanocobalamin for most people.

  • You are vegan and want a chewable B12 (the 500 or 1,000 µg option is enough for most)
  • You are older or take metformin or acid-reducing medicines and want to keep B12 topped up
  • You eat animal foods regularly and have no absorption problems
  • You are choosing the 5,000 µg option without advice: it costs more and is rarely needed
  • You have numbness, tingling or unexplained tiredness: see your GP for a blood test first
The science

Vitamin B12· evidence: Strong

Vitamin B12 is needed to make red blood cells and keep the nervous system working. It is found almost only in animal foods (meat, fish, eggs, dairy) and fortified foods, so vegans need a reliable source from fortified foods or a supplement. Older adults and people taking metformin or acid-reducing medicines absorb less B12 from food.

For these groups, B12 supplements are well proven to raise B12 levels and prevent deficiency. If you already eat animal foods and absorb B12 normally, extra B12 has not been shown to boost energy.

The body absorbs only a small share of a large oral dose, which is why many products use 500 to 1,000 µg. Methylcobalamin, cyanocobalamin and other forms all work; there is no good evidence that one form is better for most people. Pernicious anaemia and other absorption problems need a diagnosis and usually injections from your GP.

Authorised health claim
Vitamin B12 contributes to normal energy-yielding metabolism. Vitamin B12 contributes to normal functioning of the nervous system. Vitamin B12 contributes to normal homocysteine metabolism. Vitamin B12 contributes to normal psychological function. Vitamin B12 contributes to normal red blood cell formation. Vitamin B12 contributes to the normal function of the immune system. Vitamin B12 contributes to the reduction of tiredness and fatigue. Vitamin B12 has a role in the process of cell division. (Applies where a daily dose gives at least 15% of the NRV, i.e. 0.375 µg.)

Typical dose: Adults need about 1.5 µg a day (NRV on labels: 2.5 µg). Vegans: at least 10 µg a day or 2,000 µg a week (Vegan Society guidance). Supplements commonly give 10 to 1,000 µg.

Safety: No upper limit has been set because B12 has very low toxicity; the UK Expert Group on Vitamins and Minerals considered 2,000 µg a day from supplements unlikely to cause harm. Do not self-treat numbness, tingling, a sore tongue or unexplained tiredness: see your GP, as these can be signs of deficiency or pernicious anaemia that needs proper testing. Tell your doctor you take B12 before blood tests, as it raises your B12 result.
