Iodine (potassium iodide), 60 capsules
£8.00 for 60 capsules at Healf. That works out at 9p per 150 µg iodine, which ranks it 7th of the 8 potassium iodide products we price across 3 UK retailers.
At one 150 µg dose a day, this pack lasts 3 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 60 ÷ 1 per serving = 60
- In the pack: 60 × 225 µg = 13.5 mg
- £8.00 ÷ 13.5 mg × 150 µg = 8.89p per 150 µg iodine
- A week 8.89p × 7 = 62p · a month × 30 = £2.67 · a year × 365 = £32.44
- Amount per serving: stated on the label.
