How we worked it out

L-Theanine

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 100 mg = 9 g
  • £28.95 ÷ 9 g × 200 mg = 64.3p per 200 mg
  • A week 64.3p × 7 = £4.50 · a month × 30 = £19.30 · a year × 365 = £234.82
  • Amount per serving: stated on the label.

Pantothenic acid (B5)

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 6 mg = 540 mg
  • £28.95 ÷ 540 mg × 500 mg = £26.81 per 500 mg
  • A week £26.81 × 7 = £187.64 · a month × 30 = £804.17 · a year × 365 = £9784.03
  • Amount per serving: stated on the label.

Vitamin B6

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 1.4 mg = 126 mg
  • £28.95 ÷ 126 mg × 50 mg = £11.49 per 50 mg
  • A week £11.49 × 7 = £80.42 · a month × 30 = £344.64 · a year × 365 = £4193.15
