L-Glutamine

Also called glutamine.

The best price per 5 g and per month, form by form, across 9 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing L-Glutamine

We count the L-glutamine a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine L-Glutamine with other ingredients are listed separately, because their price buys more than L-glutamine. 5 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

L-glutamine

Prices last checked: . Ranked purely by price per 5 g — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

That is by price per 5 g, across 9 UK retailers and 29 products, with every price checked daily; the table above shows the working for each.

What is the best price per 5 g of L-Glutamine today?

6p per 5 g, for Glutamine Peptides Powder at Bulk (6p per 5 g, £1.80 a month), on 20 October 2026. The dearest of the 29 products we price is £2.67 per 5 g, and the middle one is 65p.

At one 5 g dose a day, the packs we price last from 9 days to 7 months; the middle one lasts 50 days. Each row says how long its pack lasts at the dose you enter.

What does “per 5 g” mean?

It is the unit we use to put every product on the same scale: the price of 5 g of L-glutamine, 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.
