How we worked it out

Electrolytes

  • Servings: 30 ÷ 1 per serving = 30

  • £31.95 ÷ 30 servings × 1 serving = £1.06 per serving
  • A week £1.06 × 7 = £7.46 · a month × 30 = £31.95 · a year × 365 = £388.73
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Caffeine

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 100 mg = 3 g
  • £31.95 ÷ 3 g × 200 mg = £2.13 per 200 mg
  • A week £2.13 × 7 = £14.91 · a month × 30 = £63.90 · a year × 365 = £777.45
  • Amount per serving: stated on the label.

Calcium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 20 mg = 600 mg

Potassium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 200 mg = 6 g
  • £31.95 ÷ 6 g × 200 mg = £1.06 per 200 mg potassium
  • A week £1.06 × 7 = £7.46 · a month × 30 = £31.95 · a year × 365 = £388.73
