The best price per 50 mg silica (as labelled) and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing silica

We count the silica (as labelled) a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Silica comes as bamboo extract, horsetail and orthosilicic 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 silica with other ingredients are listed separately, because their price buys more than silica (as labelled). 50 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

How we work out these prices

We count the silica (as labelled) a product provides, not the weight of the whole compound it comes in. If a label states the silica (as labelled) amount, we use it. If it only gives the compound's weight, we estimate using a published conversion factor and mark the figure “estimated”. If we cannot tell which the number means, the product is left out until it can be confirmed.

What does “per 50 mg silica (as labelled)” mean?

Why are the silica 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: Bamboo extract; Horsetail; Orthosilicic 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.
