How we worked it out

Vitamin D3

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 1,000 IU = 90,000 IU
  • £12.26 ÷ 90,000 IU × 1,000 IU = 13.6p per 1,000 IU
  • A week 13.6p × 7 = 95p · a month × 30 = £4.09 · a year × 365 = £49.72
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 100 µg = 9 mg
  • £12.26 ÷ 9 mg × 100 µg = 13.6p per 100 µg
  • A week 13.6p × 7 = 95p · a month × 30 = £4.09 · a year × 365 = £49.72
  • Amount per serving: stated on the label.
