Eight vitamins, one job description. Thiamine, riboflavin, niacin, B5, B6, biotin, folate, B12. They work as a set — each one a cofactor in the chain that turns what you eat into ATP, the molecule your cells actually spend. Take one in isolation and you're pulling a single thread out of a weave. Two of them are worth reading the label for. B12 and folate come in cheap forms — cyanocobalamin and folic acid — that the body has to convert before it can use them, a conversion some people manage poorly. Ours are the methylated forms, methylcobalamin and methylfolate, already in the state the body uses. Plus inositol, a B-adjacent compound the nervous system draws on. The B vitamins as a group contribute to normal energy-yielding metabolism, normal psychological function, normal function of the nervous system, and the reduction of tiredness and fatigue.* One tablet with breakfast. B vitamins are water-soluble and mildly energising, so mornings suit them better than evenings. If your urine turns bright yellow an hour later, that's riboflavin doing exactly what it should. Ninety tablets. Vegan, allergen-free. Bottle or refill pouch. *EFSA-authorised health claims for the B vitamins as a group.
