How we worked it out

Vitamin D3

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 1,000 IU = 20,000 IU
  • £6.45 ÷ 20,000 IU × 1,000 IU = 32.3p per 1,000 IU
  • A week 32.3p × 7 = £2.26 · a month × 30 = £9.68 · a year × 365 = £117.71
  • Amount per serving: stated on the label.

Elderberry

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 40 mg = 800 mg
  • £6.45 ÷ 800 mg × 500 mg = £4.03 per 500 mg
  • A week £4.03 × 7 = £28.22 · a month × 30 = £120.94 · a year × 365 = £1471.41
  • Amount per serving: extract weight stated on the label.

Vitamin C

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 1 g = 20 g
  • £6.45 ÷ 20 g × 1 g = 32.3p per 1 g
  • A week 32.3p × 7 = £2.26 · a month × 30 = £9.68 · a year × 365 = £117.71
  • Amount per serving: stated on the label.

Zinc

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 2.5 mg = 50 mg
  • £6.45 ÷ 50 mg × 15 mg = £1.94 per 15 mg zinc
  • A week £1.94 × 7 = £13.55 · a month × 30 = £58.05 · a year × 365 = £706.28
  • Amount per serving: stated on the label.
