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). 10 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Prices last checked: . Ranked purely by price per 10 mg silica (as labelled) — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

Only combination products for this form

The 6 products here contain silica alongside other ingredients, so they are not ranked against single-ingredient products. Their price per dose counts the silica only.

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.
