Betaine (TMG)

Also called betaine anhydrous, tmg, trimethylglycine, betaine.

The best price per 2.5 g and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing betaine (TMG)

We count the betaine anhydrous a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine betaine (TMG) with other ingredients are listed separately, because their price buys more than betaine anhydrous. 2.5 g 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 betaine (TMG) cheapest in the UK?

On 20 October 2026, the cheapest betaine (TMG) per dose from a UK seller was TMG Pro Powder at Healf (29p per 2.5 g, £8.71 a month). Then TMG Betaine 1000mg Tabs at Healf (34p per 2.5 g, £10.29 a month) and TMG 1000mg at Healf (35p per 2.5 g, £10.62 a month). That is by price per 2.5 g, across 1 UK retailer and 7 products, with every price checked daily; the table above shows the working for each.

What is the best price per 2.5 g of betaine (TMG) today?

29p per 2.5 g, for TMG Pro Powder at Healf (29p per 2.5 g, £8.71 a month), on 20 October 2026. The dearest of the 7 products we price is £4.46 per 2.5 g, and the middle one is 55p.

How much does betaine (TMG) cost per month?

At one 2.5 g dose a day, the cheapest works out at £8.71 a month, for TMG Pro Powder at Healf, on 20 October 2026. Across the 7 products we price it runs from £8.71 to £133.88 a month. A month is 30 days, and the figure follows the dose you enter in the table.

How long does a pack of betaine (TMG) last?

At one 2.5 g dose a day, the packs we price last from 5 days to 48 days; the middle one lasts 36 days. Each row says how long its pack lasts at the dose you enter.

What does “per 2.5 g” mean?

It is the unit we use to put every product on the same scale: the price of 2.5 g of betaine anhydrous, 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 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.
