  • Amount per serving: stated on the label.

CoQ10

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 20 mg = 600 mg
  • £29.99 ÷ 600 mg × 100 mg = £5.00 per 100 mg
  • A week £5.00 × 7 = £34.99 · a month × 30 = £149.95 · a year × 365 = £1824.39

  • Amount per serving: stated on the label.

Vitamin A

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 200 µg = 6 mg

Vitamin C

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 20 mg = 600 mg
