B vitamins support energy metabolism and blood health. Most people get enough from food; vegans often need reliable B12 sources or supplements. This is general information — book GP Carely if you have fatigue, neurological symptoms or blood-test questions.
Everyday food sources
Wholegrains, eggs, dairy, meat, fish, legumes, leafy greens and fortified cereals cover many B vitamins. B12 is mainly in animal foods and fortified products. Folate is rich in greens and pulses — important before and during pregnancy under NHS guidance.
Supplements vs food
Food-first is preferred unless a clinician advises otherwise. High-dose supplements can interact with medicines. Do not self-treat serious fatigue without checking for other causes.
Frequently Asked Questions
Should I take a B-complex tablet?
