Vitamin B5

How much vitamin B5 do I need?

You need about 6 mg of B5 a day if you're a man and 4 mg if you're a woman. A B5 tablet, usually calcium pantothenate, is a simple top-up when your diet isn't covering it.

Is Vitamin B5 right for you?

B5 is one of the simplest vitamins to talk through, because almost no one runs short and no problems have been reported. These are the questions our naturopaths ask in store.

A good fit if

Your diet is patchy or limited, and you want to cover B5 on its own
You'd rather take one nutrient than a full B complex
You understand the label statement: a supplement only helps if your diet isn't meeting your needs

Check with us first if

You're pregnant or breastfeeding and it's a high-strength product. Your needs rise slightly, but we couldn't find safety data for supplements at these doses.
Acne or hair loss is the reason you're buying. We couldn't find a trial of B5 tablets alone for either, and a naturopath can look at the whole picture with you.
The product contains pantethine. That's a different compound from B5, and its Australian status needs checking.
You take prescription medicines. Check with your doctor, pharmacist or our naturopaths before you start.

How the forms compare

Calcium pantothenate. Best known for: The standard form to swallow, in single B5 tablets and most B complexes. Absorption: We have no head-to-head absorption comparison between the oral forms. Typical use: Tablets and capsules. Schedule 1 item 1101, allowed with no conditions and no dose cap.
Sodium pantothenate. Best known for: Another oral salt of the same vitamin. Absorption: We found no dedicated trial. Typical use: Oral supplements. Schedule 1 item 4624, allowed with no conditions.
Panthenol and dexpanthenol. Best known for: The skincare forms. Panthenol is converted to pantothenic acid in the body, and dexpanthenol is its biologically active D-form. Absorption: Used mainly on the skin. The only hair trial with dexpanthenol gave it by injection, combined with biotin, so it tells us nothing about a tablet. Typical use: Creams, hair and skin products. There's no concentration limit, whereas pantothenic acid itself is capped at 0.1% on the skin.
Pantethine. Best known for: A derivative, not vitamin B5 itself: two pantothenic acid molecules linked through cysteamine. Absorption: A different compound. Its trial used 600 to 900 mg a day, many times the daily intake figure. Typical use: Not a Schedule 1 ingredient name, so its Australian status needs checking. It was studied for cholesterol, which is something to discuss with your doctor.

Common questions

Does vitamin B5 help acne?

We can't tell you it does. Acne is one of the most common reasons people buy high-strength B5, so we looked for the evidence, and we couldn't find a single trial of pantothenic acid for acne. That doesn't prove it doesn't work. It means the claim hasn't been tested well enough for us to make it. If acne is why you're here, talk to one of our naturopaths about the whole picture.

Does vitamin B5 help with hair loss?

Not on the evidence we could find. One trial gave women calcium pantothenate as one of four active treatments, with no placebo group, and its summary doesn't report how the pantothenate-only group did. The other gave dexpanthenol by weekly injection, combined with biotin, and compared two brands rather than a placebo. Neither tells you what a B5 tablet would do. If you're losing hair, it's worth talking to your health professional about why.

Is pantethine the same as vitamin B5?

No. Pantethine is a related compound, made of two pantothenic acid molecules joined through cysteamine, and it's a separate substance. It's the form behind the one well-designed positive trial in this area, but that trial used 600 to 900 mg a day in 32 people, and it was about cholesterol, which is a question for your doctor. Pantethine also isn't an ingredient name on Australia's permitted ingredients list (Schedule 1), so its status in a listed medicine needs checking.

How much, and when

Reference values. Australia hasn't set an RDI for pantothenic acid, because "there are no data to set EARs". It uses an Adequate Intake instead: 6 mg a day for adult men and 4 mg for adult women. It's 5 mg in pregnancy and 6 mg while breastfeeding. Children need from 1.7 mg for young babies up to 5 or 6 mg in the teenage years.

Typical supplemental range. There's no established supplement dose. B5 products and B complexes usually contain far more than the 4 to 6 mg daily figure. That isn't known to be harmful, but it doesn't do anything a normal diet doesn't, unless your diet is falling short.

Upper level. None has been set. In the reference values' own words: "A UL cannot be determined at this stage. There are no reports of adverse effects of oral pantothenic acid in either humans or animals on which to base a quantitative estimate." That means there are no reports to base a limit on. It doesn't mean a high dose was tested and found safe.

Worth knowing. Australia's permitted ingredients list (Schedule 1) sets no dose limit for any B5 ingredient taken by mouth. What you need depends on your age, diet and health, so talk to one of our naturopaths.

Food sources

Food first, where the diet allows it.

Almost every food: our sources don't give per-serve figures yet, so we won't guess

Before you start

If any of these sound like you, talk to one of our naturopaths or your doctor before you start.

Pregnancy and breastfeeding. Intake figures are known, but the safety of high-dose supplements hasn't been studied.
Any prescription medicine. We found no interaction data for pantothenic acid.
Pantethine products. It's a different compound, and not a Schedule 1 ingredient name.
If you take prescription medicines, check with your doctor, pharmacist or our naturopaths before you start.

The evidence, and its limits

Adults need 6 mg of pantothenic acid a day for men and 4 mg for women (an Adequate Intake). (NHMRC nutrient reference values)
No upper limit is set, as there are "no reports of adverse effects of oral pantothenic acid" to base one on. (NHMRC nutrient reference values)
Calcium pantothenate, sodium pantothenate, panthenol and dexpanthenol are all allowed with no oral dose cap. (Schedule 1, items 1101, 1758, 3675, 3678, 3679, 4624)
The one oral hair trial using calcium pantothenate had four active groups and no placebo group. (DOI record)
Six trained cyclists on a pantethine and pantothenic acid mix showed no change in performance (P = 0.58). (DOI record)

How it works

B5's main job is building coenzyme A. Picture coenzyme A as a forklift inside your cells. It picks up pieces of fat, carbohydrate and protein and carries them through the reactions that break them down or build them into something new. Your body does this all day, every day, which is why it needs a steady supply. You rarely have to think about it, though, because B5 is in almost everything you eat, and most people get enough from food without trying. Australia's reference values don't even set a Recommended Dietary Intake for it. There wasn't enough data to work one out, so there's an Adequate Intake instead.

The Australian rules

Vitamin B5 is one of the least restricted vitamins on Australia's permitted ingredients list (Schedule 1, Determination No. 2 of 2026). Calcium pantothenate (item 1101), sodium pantothenate (item 4624), panthenol (item 3675) and dexpanthenol (item 1758) are allowed in listed medicines with no conditions, warnings or dose cap. Pantothenic acid (item 3678) has one condition: "When used topically, the concentration in the medicine must be no more than 0.1%." There's no condition on taking it by mouth. Pantothenic acid polypeptide (item 3679) is an excipient only, for use on the skin, at no more than 0.1%, and not for the eye. Pantethine isn't a Schedule 1 ingredient name. Being allowed isn't the government endorsing a product or any claim made for it.

Read the instrument: Schedule 1, items 1101, 1758, 3675, 3678, 3679, 4624.
