How we worked it out

Iron

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 20 mg = 1.2 g
  • £12.50 ÷ 1.2 g × 14 mg = 14.6p per 14 mg iron
  • A week 14.6p × 7 = £1.02 · a month × 30 = £4.37 · a year × 365 = £53.23
  • Amount per serving: stated on the label.

L-Lysine

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 1 g = 60 g
  • £12.50 ÷ 60 g × 1 g = 20.8p per 1 g
  • A week 20.8p × 7 = £1.46 · a month × 30 = £6.25 · a year × 365 = £76.04
  • Amount per serving: stated on the label.

Vitamin B12

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 250 µg = 15 mg
  • £12.50 ÷ 15 mg × 1 mg = 83.3p per 1 mg
  • A week 83.3p × 7 = £5.83 · a month × 30 = £25.00 · a year × 365 = £304.17
  • Amount per serving: stated on the label.
