How we worked it out

Vitamin D3

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 4,000 IU = 120,000 IU
  • £21.42 ÷ 120,000 IU × 1,000 IU = 17.8p per 1,000 IU
  • A week 17.8p × 7 = £1.25 · a month × 30 = £5.36 · a year × 365 = £65.15
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 90 µg = 2.7 mg
  • £21.42 ÷ 2.7 mg × 100 µg = 79.3p per 100 µg
  • A week 79.3p × 7 = £5.55 · a month × 30 = £23.80 · a year × 365 = £289.57
  • Amount per serving: stated on the label.
