How we worked it out

Electrolytes

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 1 serving = 15 servings
  • £27.49 ÷ 15 servings × 1 serving = £1.83 per serving
  • A week £1.83 × 7 = £12.83 · a month × 30 = £54.98 · a year × 365 = £668.92
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 50 mg = 750 mg
  • £27.49 ÷ 750 mg × 500 mg = £18.33 per 500 mg calcium
  • A week £18.33 × 7 = £128.29 · a month × 30 = £549.80 · a year × 365 = £6689.23
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 75 mg = 1.13 g
  • £27.49 ÷ 1.13 g × 100 mg = £2.44 per 100 mg magnesium
  • A week £2.44 × 7 = £17.10 · a month × 30 = £73.31 · a year × 365 = £891.90
  • Amount per serving: stated on the label.

Potassium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 200 mg = 3 g
  • £27.49 ÷ 3 g × 200 mg = £1.83 per 200 mg potassium
  • A week £1.83 × 7 = £12.83 · a month × 30 = £54.98 · a year × 365 = £668.92
  • Amount per serving: stated on the label.

Tart cherry

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 480 mg = 7.2 g
  • £27.49 ÷ 7.2 g × 480 mg = £1.83 per 480 mg
  • A week £1.83 × 7 = £12.83 · a month × 30 = £54.98 · a year × 365 = £668.92
  • Amount per serving: extract weight stated on the label.
