Vitamin B9, commonly known as folate (or folic acid in its supplement form), is especially well known for its importance before and during pregnancy – but it matters for everyone. It contributes to normal blood formation, normal amino acid synthesis, the reduction of tiredness and fatigue, and normal psychological function, and it plays a role in the process of cell division.
Folate is the natural form found in foods like dark leafy greens, beans and eggs; folic acid is the synthetic form used in supplements and fortified foods, and it's absorbed particularly efficiently. Because your body doesn't store folate long-term, a regular intake matters. Anyone who is pregnant or planning to be should follow NHS advice on folic acid specifically – you can read more in the full explainer.
