How we worked it out

Calcium

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 400 mg = 8 g
  • £5.15 ÷ 8 g × 500 mg = 32.2p per 500 mg calcium
  • A week 32.2p × 7 = £2.25 · a month × 30 = £9.66 · a year × 365 = £117.48
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 60 mg = 1.2 g
  • £5.15 ÷ 1.2 g × 100 mg = 42.9p per 100 mg magnesium
  • A week 42.9p × 7 = £3.00 · a month × 30 = £12.88 · a year × 365 = £156.65
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 60 mg = 1.2 g
  • £5.15 ÷ 1.2 g × 1 g = £4.29 per 1 g
  • A week £4.29 × 7 = £30.04 · a month × 30 = £128.75 · a year × 365 = £1566.46
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 400 IU = 8,000 IU
  • £5.15 ÷ 8,000 IU × 1,000 IU = 64.4p per 1,000 IU
  • A week 64.4p × 7 = £4.51 · a month × 30 = £19.31 · a year × 365 = £234.97
  • Amount per serving: stated on the label.

Zinc

  • Servings: 20 ÷ 1 per serving = 20
  • In the pack: 20 × 5 mg = 100 mg
  • £5.15 ÷ 100 mg × 15 mg = 77.3p per 15 mg zinc
  • A week 77.3p × 7 = £5.41 · a month × 30 = £23.18 · a year × 365 = £281.96
