How we worked it out

Vitamin D3

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 600 IU = 18,000 IU
  • £6.83 ÷ 18,000 IU × 1,000 IU = 37.9p per 1,000 IU
  • A week 37.9p × 7 = £2.66 · a month × 30 = £11.38 · a year × 365 = £138.50
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 30 µg = 900 µg
  • £6.83 ÷ 900 µg × 100 µg = 75.9p per 100 µg
  • A week 75.9p × 7 = £5.31 · a month × 30 = £22.77 · a year × 365 = £276.99
  • Amount per serving: stated on the label.
