How we worked it out

Glycine

  • Servings: 60 ÷ 2 per serving = 30
  • In the pack: 30 × 600 mg = 18 g
  • £38.99 ÷ 18 g × 3 g = £6.50 per 3 g
  • A week £6.50 × 7 = £45.49 · a month × 30 = £194.95 · a year × 365 = £2371.89
  • Amount per serving: stated on the label.

N-Acetyl Cysteine

  • Servings: 60 ÷ 2 per serving = 30
  • In the pack: 30 × 600 mg = 18 g
  • £38.99 ÷ 18 g × 600 mg = £1.30 per 600 mg
  • A week £1.30 × 7 = £9.10 · a month × 30 = £38.99 · a year × 365 = £474.38
  • Amount per serving: stated on the label.
