Selenium, 90 capsules
£5.78 for 90 capsules at Healf. That works out at 3p per 100 µg selenium, which ranks it 2nd of the 10 selenium selenomethionine products we price across 2 UK retailers.
At one 100 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: 90 ÷ 1 per serving = 90
- In the pack: 90 × 200 µg = 18 mg
- £5.78 ÷ 18 mg × 100 µg = 3.21p per 100 µg selenium
- A week 3.21p × 7 = 22p · a month × 30 = 96p · a year × 365 = £11.72
- Amount per serving: stated on the label.
