Magnesium Powder, 107 g
£27.42 for 107 g at Healf. That works out at 17p per 100 mg magnesium, which ranks it 16th of the 38 magnesium citrate products we price across 12 UK retailers.
At one 100 mg dose a day, this pack lasts 5 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 107 ÷ 1.7 per serving = 62.9
- In the pack: 62.9 × 250 mg = 15.7 g
- £27.42 ÷ 15.7 g × 100 mg = 17.4p per 100 mg magnesium
- A week 17.4p × 7 = £1.22 · a month × 30 = £5.23 · a year × 365 = £63.60
