The same vitamin under two names, which catches people comparing products. Natures Aid label theirs vitamin B1; the older literature calls it thiamine.

It is water soluble and not stored to any real extent, so it needs to come from food or a supplement regularly rather than being built up.

Viridian's High One pairs B1 with the rest of the B group, which is the more sensible default – the B vitamins work together and taking one alone at high strength over a long period is generally not the approach.

Natures Aid's 100mg is the single-vitamin option for anyone who wants it. Both come in sensible counts, and the larger packs work out better per capsule.

With food, and in the morning if you find B vitamins at all stimulating. Check any multivitamin you already take for overlap before adding a single B vitamin.

If you are pregnant, breastfeeding or on prescribed medication, ask a pharmacist before starting a high-strength single vitamin.

FAQ

Is thiamine the same as vitamin B1?

Yes, two names for the same vitamin.

Should I take it alone or in a complex?

A complex suits most people, since the B vitamins work together.

Is B1 stored in the body?

Not to any real extent – it is water soluble, so it needs to come from food or a supplement regularly.

When should I take it?

With a meal. Earlier in the day suits people who find the B group a little stimulating.
