How we worked it out

Creatine

  • Servings: 600 ÷ 5 per serving = 120
  • In the pack: 120 × 3 g = 360 g
  • £22.49 ÷ 360 g × 5 g = 31.2p per 5 g
  • A week 31.2p × 7 = £2.19 · a month × 30 = £9.37 · a year × 365 = £114.01
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 600 ÷ 5 per serving = 120
  • In the pack: 120 × 56 mg = 6.72 g
  • £22.49 ÷ 6.72 g × 100 mg = 33.5p per 100 mg magnesium
  • A week 33.5p × 7 = £2.34 · a month × 30 = £10.04 · a year × 365 = £122.16
  • Amount per serving: stated on the label.
