How we worked it out

Selenium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 165 µg = 4.95 mg
  • £7.95 ÷ 4.95 mg × 100 µg = 16.1p per 100 µg selenium
  • A week 16.1p × 7 = £1.12 · a month × 30 = £4.82 · a year × 365 = £58.62
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 120 mg = 3.6 g
  • £7.95 ÷ 3.6 g × 1 g = £2.21 per 1 g
  • A week £2.21 × 7 = £15.46 · a month × 30 = £66.25 · a year × 365 = £806.04
  • Amount per serving: stated on the label.

Vitamin E

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 40 mg = 1.2 g
  • £7.95 ÷ 1.2 g × 268 mg = £1.78 per 268 mg
  • A week £1.78 × 7 = £12.43 · a month × 30 = £53.26 · a year × 365 = £648.06
