How we worked it out

Vitamin C

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 500 mg = 45 g
  • £5.00 ÷ 45 g × 1 g = 11.1p per 1 g
  • A week 11.1p × 7 = 78p · a month × 30 = £3.33 · a year × 365 = £40.56
  • Amount per serving: stated on the label.

Zinc

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 15 mg = 1.35 g
  • £5.00 ÷ 1.35 g × 15 mg = 5.56p per 15 mg zinc
  • A week 5.56p × 7 = 39p · a month × 30 = £1.67 · a year × 365 = £20.28
  • Amount per serving: stated on the label.
