Magnesium Citrate Capsules
£15.98 for 120 servings at WeightWorld. That works out at 3p per 100 mg magnesium, which ranks it 8th of the 79 magnesium blends and other forms we price across 15 UK retailers.
At one 100 mg dose a day, this pack lasts 1.5 years. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- In the pack: 120 × 444 mg = 53.3 g
- £15.98 ÷ 53.3 g × 100 mg = 3p per 100 mg magnesium
- A week 3p × 7 = 21p · a month × 30 = 90p · a year × 365 = £10.95
- Amount per serving: stated on the label.
