At one 100 mg dose a day, this pack lasts 28 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Magnesium

  • Servings: 28 ÷ 1 per serving = 28
  • In the pack: 28 × 100 mg = 2.8 g
  • £54.99 ÷ 2.8 g × 100 mg = £1.96 per 100 mg magnesium
  • A week £1.96 × 7 = £13.75 · a month × 30 = £58.92 · a year × 365 = £716.83
  • Amount per serving: stated on the label.

Calcium

  • Servings: 28 ÷ 1 per serving = 28
  • In the pack: 28 × 30 mg = 840 mg
  • £54.99 ÷ 840 mg × 500 mg = £32.73 per 500 mg calcium
  • A week £32.73 × 7 = £229.12 · a month × 30 = £981.96 · a year × 365 = £11947.23
  • Amount per serving: stated on the label.

Electrolytes

  • Servings: 28 ÷ 1 per serving = 28
  • In the pack: 28 × 1 serving = 28 servings
  • £54.99 ÷ 28 servings × 1 serving = £1.96 per serving
  • A week £1.96 × 7 = £13.75 · a month × 30 = £58.92 · a year × 365 = £716.83
  • Amount per serving: priced per serving — compare what each serving contains before choosing.
