Biotin

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 80 µg = 4.8 mg
  • £20.94 ÷ 4.8 mg × 5 mg = £21.81 per 5 mg
  • A week £21.81 × 7 = £152.69 · a month × 30 = £654.38 · a year × 365 = £7961.56
  • Amount per serving: stated on the label.

Folate

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 400 µg = 24 mg
