Magnesium Effervescent, 20 tablets
£6.45 for 20 tablets at Higher Nature. That works out at 16p per 100 mg magnesium, which ranks it 42nd of the 79 magnesium blends and other forms we price across 15 UK retailers.
At one 100 mg dose a day, this pack lasts 40 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 × 200 mg = 4 g
- £6.45 ÷ 4 g × 100 mg = 16.1p per 100 mg magnesium
- A week 16.1p × 7 = £1.13 · a month × 30 = £4.84 · a year × 365 = £58.86
- Amount per serving: stated on the label.
