How we worked it out

Vitamin D3

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 5,000 IU = 900,000 IU
  • £38.06 ÷ 900,000 IU × 1,000 IU = 4.23p per 1,000 IU
  • A week 4.23p × 7 = 30p · a month × 30 = £1.27 · a year × 365 = £15.44
  • Amount per serving: stated on the label.

Vitamin A

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 900 µg = 162 mg
  • £38.06 ÷ 162 mg × 800 µg = 18.8p per 800 µg
  • A week 18.8p × 7 = £1.32 · a month × 30 = £5.64 · a year × 365 = £68.60
  • Amount per serving: stated on the label.

Vitamin K1

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 1 mg = 180 mg
  • £38.06 ÷ 180 mg × 100 µg = 2.11p per 100 µg
  • A week 2.11p × 7 = 15p · a month × 30 = 63p · a year × 365 = £7.72
  • Amount per serving: stated on the label.
