Iodine 150µg, 180 tablets
£7.50 for 180 tablets at Lamberts Healthcare (Nature's Best). That works out at 4p per 150 µg iodine, which ranks it 6th of the 8 potassium iodide products we price across 3 UK retailers.
At one 150 µg dose a day, this pack lasts 6 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 180 ÷ 1 per serving = 180
- In the pack: 180 × 150 µg = 27 mg
- £7.50 ÷ 27 mg × 150 µg = 4.17p per 150 µg iodine
- A week 4.17p × 7 = 29p · a month × 30 = £1.25 · a year × 365 = £15.21
- Amount per serving: stated on the label.
