How we worked it out

Vitamin D3

  • In the pack: 125 × 2,000 IU = 250,000 IU
  • £17.99 ÷ 250,000 IU × 1,000 IU = 7.2p per 1,000 IU
  • A week 7.2p × 7 = 50p · a month × 30 = £2.16 · a year × 365 = £26.27
  • Amount per serving: stated on the label.

Vitamin K2

  • In the pack: 125 × 50 µg = 6.25 mg
  • £17.99 ÷ 6.25 mg × 100 µg = 28.8p per 100 µg
  • A week 28.8p × 7 = £2.01 · a month × 30 = £8.64 · a year × 365 = £105.06
  • Amount per serving: stated on the label.
