How we worked it out

Folate

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 400 µg = 72 mg
  • £8.00 ÷ 72 mg × 400 µg = 4.44p per 400 µg
  • A week 4.44p × 7 = 31p · a month × 30 = £1.33 · a year × 365 = £16.22
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 400 IU = 72,000 IU
  • £8.00 ÷ 72,000 IU × 1,000 IU = 11.1p per 1,000 IU
  • A week 11.1p × 7 = 78p · a month × 30 = £3.33 · a year × 365 = £40.56
  • Amount per serving: stated on the label.
