Extend-Release Magnesium, 60 capsules
£7.35 for 60 capsules at Healf. That works out at 5p per 100 mg magnesium, which ranks it 23rd of the 79 magnesium blends and other forms we price across 15 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: 60 ÷ 1 per serving = 60
- In the pack: 60 × 250 mg = 15 g
- £7.35 ÷ 15 g × 100 mg = 4.9p per 100 mg magnesium
- A week 4.9p × 7 = 34p · a month × 30 = £1.47 · a year × 365 = £17.89
- Amount per serving: stated on the label.
