How we worked it out

  • Servings: 375 ÷ 25 per serving = 15
  • In the pack: 15 × 20 g = 300 g
  • £16.99 ÷ 300 g × 25 g = £1.42 per 25 g protein
  • A week £1.42 × 7 = £9.91 · a month × 30 = £42.48 · a year × 365 = £516.78
  • Amount per serving: stated on the label.

Collagen

  • Servings: 375 ÷ 25 per serving = 15
  • In the pack: 15 × 10 g = 150 g
  • £16.99 ÷ 150 g × 10 g = £1.13 per 10 g
  • A week £1.13 × 7 = £7.93 · a month × 30 = £33.98 · a year × 365 = £413.42
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 375 ÷ 25 per serving = 15
  • In the pack: 15 × 52 mg = 780 mg
  • £16.99 ÷ 780 mg × 1 g = £21.78 per 1 g
  • A week £21.78 × 7 = £152.47 · a month × 30 = £653.46 · a year × 365 = £7950.45
