How we worked it out

5-HTP

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 50 mg = 4.5 g
  • £20.64 ÷ 4.5 g × 100 mg = 45.9p per 100 mg
  • A week 45.9p × 7 = £3.21 · a month × 30 = £13.76 · a year × 365 = £167.41
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 15 mg = 1.35 g
  • £20.64 ÷ 1.35 g × 500 mg = £7.64 per 500 mg
  • A week £7.64 × 7 = £53.51 · a month × 30 = £229.33 · a year × 365 = £2790.22
  • Amount per serving: stated on the label.

Vitamin B6

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 5 mg = 450 mg
  • £20.64 ÷ 450 mg × 50 mg = £2.29 per 50 mg
  • A week £2.29 × 7 = £16.05 · a month × 30 = £68.80 · a year × 365 = £837.07
  • Amount per serving: stated on the label.

Zinc

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 2.5 mg = 225 mg
  • £20.64 ÷ 225 mg × 15 mg = £1.38 per 15 mg zinc
  • A week £1.38 × 7 = £9.63 · a month × 30 = £41.28 · a year × 365 = £502.24
  • Amount per serving: stated on the label.
