Cheapest vitamin C today: 3p per 1 g at Healf, of 112 products at 21 shops. Checked 29 October 2026.
The best price per 1 g and per month, form by form, across 21 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.
Comparing vitamin C
We count the vitamin C (ascorbate equivalent) a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Vitamin C comes as standard (ascorbic acid and ascorbates) and liposomal, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. A product with one other ingredient is ranked here with an “also contains” note; products that combine vitamin C with several others are listed separately, because their price buys more than vitamin C (ascorbate equivalent). 1 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 vitamin C cheapest in the UK?
On 29 October 2026, the cheapest vitamin C per dose from a UK seller was Vitamin C Crystals Powder - 8 oz at Healf (3p per 1 g, £1.03 a month). Then Vitamin C Powder - 250 Powder by Nature's Best - Fast Dissolving Soluble Powder - Helps Support Immune System at Lamberts Healthcare (Nature's Best) (5p per 1 g, £1.50 a month) and Vitamin C With Rosehip and Bioflavonoids Tablets at WeightWorld (5p per 1 g, £1.65 a month). That is by price per 1 g, across 21 UK retailers and 113 products, with every price checked daily; the table above shows the working for each.
What is the best price per 1 g of vitamin C today?
3p per 1 g, for Vitamin C Crystals Powder - 8 oz at Healf (3p per 1 g, £1.03 a month), on 29 October 2026. The dearest of the 113 products we price is £35.82 per 1 g, and the middle one is 26p.
How much does vitamin C cost per month?
At one 1 g dose a day, the cheapest works out at £1.03 a month, for Vitamin C Crystals Powder - 8 oz at Healf, on 29 October 2026. Across the 113 products we price it runs from 80p to £1074.50 a month. A month is 30 days, and the figure follows the dose you enter in the table.
Which vitamin C form is cheapest per dose?
On 29 October 2026: standard (ascorbic acid and ascorbates) from 3p per 1 g (Healf) and liposomal from 28p per 1 g (WeightWorld). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.
Do bigger vitamin C packs cost less per dose?
Mostly, yes: on 29 October 2026, the 9 packs that last more than six months average 8p per 1 g, against £2.94 for the 104 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 vitamin C last?
At one 1 g dose a day, the packs we price last from under a day to 1.4 years; the middle one lasts 30 days. 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 vitamin C (ascorbate equivalent), 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 vitamin c 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: Standard (ascorbic acid and ascorbates); Liposomal.
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 29 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.
