Selenium Tablets
£14.99 for 365 servings at WeightWorld. That works out at 2p per 100 µg selenium, which ranks it 1st of the 10 other forms of selenium products we price across 6 UK retailers.
At one 100 µg dose a day, this pack lasts 2 years. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- In the pack: 365 × 200 µg = 73 mg
- £14.99 ÷ 73 mg × 100 µg = 2.05p per 100 µg selenium
- A week 2.05p × 7 = 14p · a month × 30 = 62p · a year × 365 = £7.50
- Amount per serving: stated on the label.
