Vitamin B complex supplements bring together all eight essential B vitamins in one tablet, from thiamine (B1) through to vitamin B12. Each one has its own role to play, but together they help your body turn the food you eat into energy, as well as supporting normal immune system and psychological functions, while helping to reduce tiredness and fatigue.

B vitamins are water-soluble, which means your body only stores them in small amounts, so getting enough regularly is important. Most people can get the B vitamins they need through a balanced, varied diet, but a vitamin B complex supplement can be helpful if you follow a plant-based diet, are over 65, or are planning a pregnancy.
