Ultra Magnesium, 90 capsules
£21.25 for 90 capsules at Healf. That works out at 31p per 100 mg magnesium, which ranks it 51st of the 79 magnesium blends and other forms we price across 15 UK retailers.
At one 100 mg dose a day, this pack lasts 2 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 90 ÷ 3 per serving = 30
- In the pack: 30 × 225 mg = 6.75 g
- £21.25 ÷ 6.75 g × 100 mg = 31.5p per 100 mg magnesium
- A week 31.5p × 7 = £2.20 · a month × 30 = £9.44 · a year × 365 = £114.91
- Amount per serving: stated on the label.
