How we worked it out

5-HTP

  • In the pack: 30 × 100 mg = 3 g
  • £18.98 ÷ 3 g × 100 mg = 63.3p per 100 mg
  • A week 63.3p × 7 = £4.43 · a month × 30 = £18.98 · a year × 365 = £230.92
  • Amount per serving: stated on the label.

L-Tryptophan

  • In the pack: 30 × 110 mg = 3.3 g
  • £18.98 ÷ 3.3 g × 500 mg = £2.88 per 500 mg
  • A week £2.88 × 7 = £20.13 · a month × 30 = £86.27 · a year × 365 = £1049.65
  • Amount per serving: stated on the label.

Lemon balm

  • In the pack: 30 × 20 mg = 600 mg
  • £18.98 ÷ 600 mg × 500 mg = £15.82 per 500 mg
