  • £54.99 ÷ 59.8 servings × 1 serving = 91.9p per serving
  • A week 91.9p × 7 = £6.43 · a month × 30 = £27.57 · a year × 365 = £335.41
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 377 ÷ 6.3 per serving = 59.8
  • In the pack: 59.8 × 60 mg = 3.59 g
  • £54.99 ÷ 3.59 g × 500 mg = £7.66 per 500 mg calcium
  • A week £7.66 × 7 = £53.60 · a month × 30 = £229.73 · a year × 365 = £2795.08
