How we worked it out

L-Tyrosine

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 400 mg = 24 g
  • £13.49 ÷ 24 g × 500 mg = 28.1p per 500 mg
  • A week 28.1p × 7 = £1.97 · a month × 30 = £8.43 · a year × 365 = £102.58
  • Amount per serving: stated on the label.

Iodine

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 150 µg = 9 mg
  • £13.49 ÷ 9 mg × 150 µg = 22.5p per 150 µg iodine
  • A week 22.5p × 7 = £1.57 · a month × 30 = £6.75 · a year × 365 = £82.06
  • Amount per serving: stated on the label.

Manganese

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 2.67 mg = 160.2 mg
  • £13.49 ÷ 160.2 mg × 2 mg = 16.8p per 2 mg manganese
  • A week 16.8p × 7 = £1.18 · a month × 30 = £5.05 · a year × 365 = £61.47
  • Amount per serving: stated on the label.

Selenium

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 56.8 µg = 3.41 mg
  • £13.49 ÷ 3.41 mg × 100 µg = 39.6p per 100 µg selenium
  • A week 39.6p × 7 = £2.77 · a month × 30 = £11.89 · a year × 365 = £144.61
