How we worked it out

Calcium

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 40 mg = 1.2 g
  • £55.99 ÷ 1.2 g × 500 mg = £23.33 per 500 mg calcium
  • A week £23.33 × 7 = £163.30 · a month × 30 = £699.88 · a year × 365 = £8515.15
  • Amount per serving: stated on the label.

N-Acetyl Cysteine

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 300 mg = 9 g
  • £55.99 ÷ 9 g × 600 mg = £3.73 per 600 mg
  • A week £3.73 × 7 = £26.13 · a month × 30 = £111.98 · a year × 365 = £1362.42
  • Amount per serving: stated on the label.

Quercetin

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 400 mg = 12 g
  • £55.99 ÷ 12 g × 500 mg = £2.33 per 500 mg
  • A week £2.33 × 7 = £16.33 · a month × 30 = £69.99 · a year × 365 = £851.51
  • Amount per serving: stated on the label.
