How we worked it out

Glucosamine

  • Servings: 320 ÷ 1 per serving = 320
  • In the pack: 320 × 1 g = 320 g
  • £17.99 ÷ 320 g × 1.5 g = 8.43p per 1.5 g
  • A week 8.43p × 7 = 59p · a month × 30 = £2.53 · a year × 365 = £30.78
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 320 ÷ 1 per serving = 320
  • In the pack: 320 × 20 mg = 6.4 g
  • £17.99 ÷ 6.4 g × 1 g = £2.81 per 1 g
  • A week £2.81 × 7 = £19.68 · a month × 30 = £84.33 · a year × 365 = £1025.99
