  • A week 60.6p × 7 = £4.24 · a month × 30 = £18.17 · a year × 365 = £221.03
  • Amount per serving: stated on the label.

Copper

  • Servings: 150 ÷ 10 per serving = 15
  • In the pack: 15 × 0.25 mg = 3.75 mg
  • £5.45 ÷ 3.75 mg × 1 mg = £1.45 per 1 mg copper
  • A week £1.45 × 7 = £10.17 · a month × 30 = £43.60 · a year × 365 = £530.47
  • Amount per serving: stated on the label.

  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 150 ÷ 10 per serving = 15
