Other forms of selenium

Also called selenomethionine, sodium selenite.

The best price per 100 µg selenium and per month across 6 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

Comparing selenium

Labels give selenium in micrograms, and some in milligrams: 100 µg is 100 mcg. We put every product in one unit before pricing it. Selenium comes as selenomethionine and other forms, 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 selenium with other ingredients are listed separately, because their price buys more than selenium. 100 µg 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 100 µg selenium — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

By shop

Each shop's selenium products, with where its cheapest sits in the market.

How we work out these prices

We count the elemental selenium a product provides, not the weight of the whole compound it comes in. If a label states the selenium 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.
