Liquid Selenium
£15.99 for 30 servings at Healf. That works out at 21p per 100 µg selenium, which ranks it 9th of the 10 other forms of selenium products we price across 6 UK retailers.
At one 100 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
- In the pack: 30 × 260 µg = 7.8 mg
- £15.99 ÷ 7.8 mg × 100 µg = 20.5p per 100 µg selenium
- A week 20.5p × 7 = £1.44 · a month × 30 = £6.15 · a year × 365 = £74.83
