How we worked it out

Magnesium

  • £45.57 ÷ 6 g × 100 mg = 76p per 100 mg magnesium
  • A week 76p × 7 = £5.32 · a month × 30 = £22.79 · a year × 365 = £277.22
  • Amount per serving: stated on the label.

L-Theanine

  • In the pack: 30 × 100 mg = 3 g
  • £45.57 ÷ 3 g × 200 mg = £3.04 per 200 mg
  • A week £3.04 × 7 = £21.27 · a month × 30 = £91.14 · a year × 365 = £1108.87
  • Amount per serving: stated on the label.
