How we worked it out

Vitamin D3

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 2,500 IU = 150,000 IU
  • £25.99 ÷ 150,000 IU × 1,000 IU = 17.3p per 1,000 IU
  • A week 17.3p × 7 = £1.21 · a month × 30 = £5.20 · a year × 365 = £63.24
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 55 µg = 3.3 mg
  • £25.99 ÷ 3.3 mg × 100 µg = 78.8p per 100 µg
  • A week 78.8p × 7 = £5.51 · a month × 30 = £23.63 · a year × 365 = £287.47
  • Amount per serving: stated on the label.
