How we worked it out

Vitamin D3

  • Servings: 59 ÷ 0.2 per serving = 295
  • In the pack: 295 × 5,000 IU = 1,475,000 IU
  • £27.49 ÷ 1,475,000 IU × 1,000 IU = 1.86p per 1,000 IU
  • A week 1.86p × 7 = 13p · a month × 30 = 56p · a year × 365 = £6.80
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 59 ÷ 0.2 per serving = 295
  • In the pack: 295 × 100 µg = 29.5 mg
  • £27.49 ÷ 29.5 mg × 100 µg = 9.32p per 100 µg
  • A week 9.32p × 7 = 65p · a month × 30 = £2.80 · a year × 365 = £34.01
  • Amount per serving: stated on the label.
