Your body runs on B vitamins. This family of eight essential nutrients helps convert the food you eat into energy, supports the normal function of the nervous system, and contributes to everything from normal psychological function to the maintenance of normal skin. Each one has its own distinct role, which is why they're so often taken together.
The eight B vitamins are water-soluble, so your body holds onto only small amounts at a time and relies on a regular daily intake. Most people get what they need from a varied diet – meat, fish, eggs, dairy, leafy greens and wholegrains are all good sources – but certain groups can find it harder to get enough: people following a plant-based diet, those over 65, and women who are pregnant or planning to be. A supplement can be a simple way to fill the gap.
