L-Lysine
Also called lysine, lysine hcl, lysine hydrochloride.
The best price per 1 g and per month, form by form, across 8 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.
Comparing L-Lysine
We count the L-lysine a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine L-Lysine with other ingredients are listed separately, because their price buys more than L-lysine. 1 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

How much does L-Lysine cost per month?
At one 1 g dose a day, the cheapest works out at £2.52 a month, for L-Lysine 1,000 mg at Healf, on 20 October 2026. Across the 15 products we price it runs from £2.52 to £17.67 a month. A month is 30 days, and the figure follows the dose you enter in the table.
Do bigger L-Lysine packs cost less per dose?
Mostly, yes: on 20 October 2026, the 2 packs that last more than six months average 9p per 1 g, against 25p for the 13 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 L-Lysine last?
At one 1 g dose a day, the packs we price last from 30 days to 8 months; the middle one lasts 2 months. Each row says how long its pack lasts at the dose you enter.
What does “per 1 g” mean?
It is the unit we use to put every product on the same scale: the price of 1 g of L-lysine, 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.
