  • In the pack: 30 × 1,000 IU = 30,000 IU
  • £39.99 ÷ 30,000 IU × 1,000 IU = £1.33 per 1,000 IU
  • A week £1.33 × 7 = £9.33 · a month × 30 = £39.99 · a year × 365 = £486.54
  • Amount per serving: stated on the label.

Grape seed extract

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 20 mg = 600 mg
  • £39.99 ÷ 600 mg × 300 mg = £20.00 per 300 mg
  • A week £20.00 × 7 = £139.97 · a month × 30 = £599.85 · a year × 365 = £7298.18

Vitamin B12

  • Servings: 30 ÷ 1 per serving = 30
