Alpha-lipoic acid

Also called alpha lipoic acid, ALA, lipoic acid and 3 more

r-ALA, r-lipoic acid, thioctic acid.

The best price per 300 mg and per month, form by form, across 6 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing alpha-lipoic acid

We count the alpha-lipoic acid a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Alpha-lipoic acid comes as alpha-lipoic acid and R-lipoic acid, 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 alpha-lipoic acid with other ingredients are listed separately, because their price buys more than alpha-lipoic acid. 300 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 alpha-lipoic acid cheapest in the UK?

On 20 October 2026, the cheapest alpha-lipoic acid per dose from a UK seller was Alpha Lipoic Acid Capsules at WeightWorld (5p per 300 mg, £1.54 a month). Then Alpha Lipoic Acid (ALA) Capsules 750mg at Simply Supplements (10p per 300 mg, £2.90 a month) and Alpha Lipoic Acid 300mg - Maximum Strength Ala, Antioxidant Supplement at Lamberts Healthcare (Nature's Best) (17p per 300 mg, £5.17 a month). That is by price per 300 mg, across 6 UK retailers and 10 products, with every price checked daily; the table above shows the working for each.

What is the best price per 300 mg of alpha-lipoic acid today?

5p per 300 mg, for Alpha Lipoic Acid Capsules at WeightWorld (5p per 300 mg, £1.54 a month), on 20 October 2026. The dearest of the 10 products we price is £1.67 per 300 mg, and the middle one is 53p.

How much does alpha-lipoic acid cost per month?

At one 300 mg dose a day, the cheapest works out at £1.54 a month, for Alpha Lipoic Acid Capsules at WeightWorld, on 20 October 2026. Across the 10 products we price it runs from £1.54 to £50.03 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Which alpha-lipoic acid form is cheapest per dose?

On 20 October 2026: alpha-lipoic acid from 5p per 300 mg (WeightWorld) and R-lipoic acid from £1.16 per 300 mg (Healf). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.

How long does a pack of alpha-lipoic acid last?

At one 300 mg dose a day, the packs we price last from 20 days to 1.1 years; the middle one lasts 2 months. Each row says how long its pack lasts at the dose you enter.

What does “per 300 mg” mean?

It is the unit we use to put every product on the same scale: the price of 300 mg of alpha-lipoic acid, 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 alpha-lipoic acid 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: Alpha-lipoic acid; R-lipoic acid.

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.
