5 Seaweed Blend, 60 capsules
£23.49 for 60 capsules at Healf. That works out at 78p per 150 µg iodine, which ranks it 3rd of the 3 kelp products we price across 3 UK retailers.
At one 150 µg dose a day, this pack lasts 30 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 60 ÷ 2 per serving = 30
- In the pack: 30 × 150 µg = 4.5 mg
- £23.49 ÷ 4.5 mg × 150 µg = 78.3p per 150 µg iodine
- A week 78.3p × 7 = £5.48 · a month × 30 = £23.49 · a year × 365 = £285.79
- Amount per serving: stated on the label.
