How we worked it out

Vitamin C

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 1 g = 20 g
  • £4.95 ÷ 20 g × 1 g = 24.8p per 1 g
  • A week 24.8p × 7 = £1.73 · a month × 30 = £7.43 · a year × 365 = £90.34
  • Amount per serving: stated on the label.

Zinc

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 5 mg = 100 mg
  • £4.95 ÷ 100 mg × 15 mg = 74.3p per 15 mg zinc
  • A week 74.3p × 7 = £5.20 · a month × 30 = £22.28 · a year × 365 = £271.01
  • Amount per serving: stated on the label.
