Vitamin B1

How much vitamin B1 do I need?

You need about 1.1 mg of vitamin B1 a day if you're a woman and 1.2 mg if you're a man. Choose plain B1 tablets, or get it as part of a B complex.

Is Vitamin B1 right for you?

Common questions

How much vitamin B1 do you need a day?

Australia's Nutrient Reference Values set 1.2 mg a day for adult men and 1.1 mg for adult women, and 1.4 mg in pregnancy and while breastfeeding. Children need 0.5 mg at ages 1 to 3, rising to 0.9 mg at 9 to 13. No upper limit has been set, because there isn't enough data to estimate one. Most B1 tablets use thiamine hydrochloride. What you need depends on your age, diet and health, so talk to one of our naturopaths.

Is benfotiamine the same as vitamin B1?

Not quite. Benfotiamine is a man-made, fat-soluble version of thiamine, while the vitamin B1 in most tablets is a water-soluble form such as thiamine hydrochloride. They're treated differently in Australia, too. The thiamine forms are permitted in listed medicines, but benfotiamine isn't on that list, so it can't be the active ingredient in a listed medicine here. If benfotiamine is what you're after, ask us.

The evidence, and its limits

The Australian rules

Five forms of thiamine are on Australia's permitted ingredients list (Schedule 1, Determination No. 2 of 2026), and each one is allowed in listed medicines. THIAMINE is item 4916, THIAMINE HYDROCHLORIDE is item 4917, THIAMINE NITRATE is item 4918, MONOPHOSPHOTHIAMINE is item 3404 and MONOPHOSPHOTHIAMINE DIHYDRATE is item 3405.

None of the five has any specific condition or warning statement, and there's no daily limit on any of them.

Benfotiamine isn't in Schedule 1 under that name or anything close. That means it can't be the active ingredient in an AUST L listed medicine the way the thiamine forms above can. It doesn't mean benfotiamine can't be sold in Australia at all; the way it's sold needs to be checked separately. Being allowed isn't the government endorsing any product or claim.

Read the instrument: Schedule 1, item 3404.

Not sure this is the right form for you? Ask one of our naturopaths. It is free and takes 10 minutes.

Always read the label and follow the directions for use. General information only, and not a substitute for advice from your doctor or one of our naturopaths.
