MegaMag® 10-in-1 Chews, 20 gummies
£12.79 for 20 gummies at Healf. That works out at 61p per 100 mg magnesium, which ranks it 61st of the 79 magnesium blends and other forms we price across 15 UK retailers.
At one 100 mg dose a day, this pack lasts 21 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 20 ÷ 1 per serving = 20
- In the pack: 20 × 105 mg = 2.1 g
- £12.79 ÷ 2.1 g × 100 mg = 60.9p per 100 mg magnesium
- A week 60.9p × 7 = £4.26 · a month × 30 = £18.27 · a year × 365 = £222.30
- Amount per serving: stated on the label.
