Magnesium Gummies for Kids
£16.99 for 90 servings at WeightWorld. That works out at 24p per 100 mg magnesium, which ranks it 27th of the 38 magnesium citrate products we price across 12 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
- In the pack: 90 × 80 mg = 7.2 g
- £16.99 ÷ 7.2 g × 100 mg = 23.6p per 100 mg magnesium
- A week 23.6p × 7 = £1.65 · a month × 30 = £7.08 · a year × 365 = £86.13
- Amount per serving: stated on the label.
