Can You Take Vitamin B1 and Vitamin B6 Together?

May affect absorption

The short answer

B vitamins may compete for absorption at very high supplemental doses, though at standard doses this is not clinically significant.

How to arrange timing

Standard doses are fine together. Only separate if taking mega-doses of individual B vitamins.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
