How we worked it out

Multivitamin

  • In the pack: 400 × 1 serving = 400 servings
  • £18.99 ÷ 400 servings × 1 serving = 4.75p per serving
  • A week 4.75p × 7 = 33p · a month × 30 = £1.42 · a year × 365 = £17.33
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Iron

  • In the pack: 400 × 14 mg = 5.6 g
  • £18.99 ÷ 5.6 g × 14 mg = 4.75p per 14 mg iron
  • A week 4.75p × 7 = 33p · a month × 30 = £1.42 · a year × 365 = £17.33
  • Amount per serving: stated on the label.

Magnesium

  • In the pack: 400 × 56 mg = 22.4 g
  • £18.99 ÷ 22.4 g × 100 mg = 8.48p per 100 mg magnesium
  • A week 8.48p × 7 = 59p · a month × 30 = £2.54 · a year × 365 = £30.94
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • In the pack: 400 × 16 mg = 6.4 g
  • £18.99 ÷ 6.4 g × 500 mg = £1.48 per 500 mg
  • A week £1.48 × 7 = £10.39 · a month × 30 = £44.51 · a year × 365 = £541.51
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 400 × 40.2 mg = 16.1 g
  • £18.99 ÷ 16.1 g × 200 mg = 23.6p per 200 mg potassium
  • A week 23.6p × 7 = £1.66 · a month × 30 = £7.09 · a year × 365 = £86.32
  • Amount per serving: stated on the label.

Vitamin C

  • In the pack: 400 × 84 mg = 33.6 g
  • £18.99 ÷ 33.6 g × 1 g = 56.5p per 1 g
  • A week 56.5p × 7 = £3.96 · a month × 30 = £16.96 · a year × 365 = £206.29
  • Amount per serving: stated on the label.

Vitamin E

  • In the pack: 400 × 12 mg = 4.8 g
  • £18.99 ÷ 4.8 g × 268 mg = £1.06 per 268 mg
  • A week £1.06 × 7 = £7.42 · a month × 30 = £31.81 · a year × 365 = £387.00
  • Amount per serving: stated on the label.

Zinc

  • In the pack: 400 × 10 mg = 4 g
  • £18.99 ÷ 4 g × 15 mg = 7.12p per 15 mg zinc
  • A week 7.12p × 7 = 50p · a month × 30 = £2.14 · a year × 365 = £25.99
