How we worked it out

Vitamin D3

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 2,500 IU = 150,000 IU
  • £20.99 ÷ 150,000 IU × 1,000 IU = 14p per 1,000 IU
  • A week 14p × 7 = 98p · a month × 30 = £4.20 · a year × 365 = £51.08
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 200 µg = 12 mg
  • £20.99 ÷ 12 mg × 100 µg = 17.5p per 100 µg
  • A week 17.5p × 7 = £1.22 · a month × 30 = £5.25 · a year × 365 = £63.84
  • Amount per serving: stated on the label.
