How we worked it out

Calcium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 180 mg = 5.4 g
  • £36.36 ÷ 5.4 g × 500 mg = £3.37 per 500 mg calcium
  • A week £3.37 × 7 = £23.57 · a month × 30 = £101.00 · a year × 365 = £1228.83
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 5,000 IU = 150,000 IU
  • £36.36 ÷ 150,000 IU × 1,000 IU = 24.2p per 1,000 IU
  • A week 24.2p × 7 = £1.70 · a month × 30 = £7.27 · a year × 365 = £88.48
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 180 µg = 5.4 mg
  • £36.36 ÷ 5.4 mg × 100 µg = 67.3p per 100 µg
  • A week 67.3p × 7 = £4.71 · a month × 30 = £20.20 · a year × 365 = £245.77
  • Amount per serving: stated on the label.
