Folate

Also called folic acid, vitamin B9, methylfolate and 4 more

5-mthf, L-methylfolate, quatrefolic, metafolin.

The best price per 400 µg and per month, form by form, across 12 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing folate

Labels give folate in micrograms, and some in milligrams: 400 µg is 400 mcg. We put every product in one unit before pricing it. Folate comes as folic acid and methylfolate (5-MTHF), 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 folate with other ingredients are listed separately, because their price buys more than folate. 400 µg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Methylfolate (5-MTHF)

By shop

Each shop's folate products, with where its cheapest sits in the market.

How we work out these prices

We count the amount of folate stated on the label, converting between units (for example micrograms and IU) so every product is on the same scale.

Questions

Where can I buy folate cheapest in the UK?

On 20 October 2026, the cheapest folate per dose from a UK seller was Methyl Folate 1,000 mcg at Healf (4p per 400 µg, £1.27 a month). Then 5-MTHF 5 mg at Healf (7p per 400 µg, £2.22 a month) and 5-MTHF at Healf (8p per 400 µg, £2.36 a month). That is by price per 400 µg, across 4 UK retailers and 22 products, with every price checked daily; the table above shows the working for each.

What is the best price per 400 µg of folate today?

4p per 400 µg, for Methyl Folate 1,000 mcg at Healf (4p per 400 µg, £1.27 a month), on 20 October 2026. The dearest of the 22 products we price is £1.63 per 400 µg, and the middle one is 14p.

How much does folate cost per month?

At one 400 µg dose a day, the cheapest works out at £1.27 a month, for Methyl Folate 1,000 mcg at Healf, on 20 October 2026. Across the 22 products we price it runs from £1.27 to £48.90 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Which folate form is cheapest per dose?

On 20 October 2026: folic acid from 1p per 400 µg (Healf) and methylfolate (5-MTHF) from 4p per 400 µg (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 folate packs cost less per dose?

Mostly, yes: on 20 October 2026, the 6 packs that last more than six months average 9p per 400 µg, against 27p for the 16 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 folate last?

At one 400 µg dose a day, the packs we price last from 15 days to 2.1 years; the middle one lasts 4 months. Each row says how long its pack lasts at the dose you enter.

What does “per 400 µg” mean?

It is the unit we use to put every product on the same scale: the price of 400 µg of folate, 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 folate 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: Folic acid; Methylfolate (5-MTHF).

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.
