How we worked it out

Zinc

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 10 mg = 900 mg
  • £14.99 ÷ 900 mg × 15 mg = 25p per 15 mg zinc
  • A week 25p × 7 = £1.75 · a month × 30 = £7.50 · a year × 365 = £91.19
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 150 mg = 13.5 g
  • £14.99 ÷ 13.5 g × 100 mg = 11.1p per 100 mg magnesium
  • A week 11.1p × 7 = 78p · a month × 30 = £3.33 · a year × 365 = £40.53
  • Amount per serving: stated on the label.

Vitamin B6

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 3.5 mg = 315 mg
  • £14.99 ÷ 315 mg × 50 mg = £2.38 per 50 mg
  • A week £2.38 × 7 = £16.66 · a month × 30 = £71.38 · a year × 365 = £868.47
  • Amount per serving: stated on the label.
