Potassium iodide
Also called potassium iodide, kelp.
The best price per 150 µg iodine and per month across 3 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.
Comparing iodine
Labels give iodine in micrograms, and some in milligrams: 150 µg is 150 mcg. We put every product in one unit before pricing it. Iodine comes as potassium iodide and kelp, 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 iodine with other ingredients are listed separately, because their price buys more than iodine. 150 µg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Only combination products for this form
The 89 products here contain iodine alongside other ingredients, so they are not ranked against single-ingredient products. Their price per dose counts the iodine only.
By shop
Each shop's iodine products, with where its cheapest sits in the market.
How we work out these prices
We count the elemental iodine a product provides, not the weight of the whole compound it comes in. If a label states the iodine 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.
Conversion factor used when only the compound weight is given: potassium iodide 76.4%. How we chose these.
