Vitamin B6

Also called B6, pyridoxine, pyridoxal-5-phosphate and 3 more

pyridoxal 5 phosphate, p5p, p-5-p.

The best price per 50 mg and per month, form by form, across 5 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing vitamin B6

We count the vitamin B6 a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Vitamin B6 comes as pyridoxine HCl and P-5-P (active form), and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine vitamin B6 with other ingredients are listed separately, because their price buys more than vitamin B6. 50 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Questions

Where can I buy vitamin B6 cheapest in the UK?

On 20 October 2026, the cheapest vitamin B6 per dose from a UK seller was Vitamin B6 50mg at ZipVit (3p per 50 mg, £1.00 a month). Then Vitamin B6 Tablets 50mg at Simply Supplements (4p per 50 mg, £1.11 a month) and Vitamin B6 100mg at Healf (5p per 50 mg, £1.39 a month). That is by price per 50 mg, across 5 UK retailers and 6 products, with every price checked daily; the table above shows the working for each.

What is the best price per 50 mg of vitamin B6 today?

3p per 50 mg, for Vitamin B6 50mg at ZipVit (3p per 50 mg, £1.00 a month), on 20 October 2026. The dearest of the 6 products we price is £3.61 per 50 mg, and the middle one is 5p.

How much does vitamin B6 cost per month?

At one 50 mg dose a day, the cheapest works out at £1.00 a month, for Vitamin B6 50mg at ZipVit, on 20 October 2026. Across the 6 products we price it runs from £1.00 to £108.25 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Which vitamin B6 form is cheapest per dose?

On 20 October 2026: pyridoxine HCl from 3p per 50 mg (ZipVit) and P-5-P (active form) from 28p per 50 mg (Healf). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.

Do bigger vitamin B6 packs cost less per dose?

Mostly, yes: on 20 October 2026, the 3 packs that last more than six months average 4p per 50 mg, against £1.55 for the 3 that last six months or less. The table marks the cheapest pack that lasts six months or less as the best value for anyone who would rather not buy a year at once.

How long does a pack of vitamin B6 last?

At one 50 mg dose a day, the packs we price last from 4 days to 12 months; the middle one lasts 5 months. Each row says how long its pack lasts at the dose you enter.

What does “per 50 mg” mean?

It is the unit we use to put every product on the same scale: the price of 50 mg of vitamin B6, whatever the pack size or serving size. It is a comparison unit, not a recommendation of how much to take. Use the “Your daily dose” box to see costs at the amount you actually take.

Why are the vitamin b6 forms in separate tables?

We only rank products against others of the same form, because someone buying one form would not usually see another as a like-for-like substitute on price. Forms we compare separately: Pyridoxine HCl; P-5-P (active form).

Why is a product I have seen in the shops missing?

If a retailer’s listing does not let us confirm the amount per serving, the pack size or the form, we do not guess and we do not show the product. It appears once its label has been read and confirmed.

How up to date are the prices?

Prices on this page were last checked on 20 October 2026. Every table shows the date its prices were checked. Always confirm the price on the retailer’s site before buying.

Do retailers pay to appear higher?

No. We earn a commission when you buy through our links, but the order is set only by price per dose. No retailer or brand can pay for position.
