How we worked it out

Calcium

Servings: 270 ÷ 3 per serving = 90
In the pack: 90 × 800 mg = 72 g
£10.99 ÷ 72 g × 500 mg = 7.63p per 500 mg calcium
A week 7.63p × 7 = 53p · a month × 30 = £2.29 · a year × 365 = £27.86
Amount per serving: stated on the label.

Magnesium

Servings: 270 ÷ 3 per serving = 90
In the pack: 90 × 375 mg = 33.8 g
£10.99 ÷ 33.8 g × 100 mg = 3.26p per 100 mg magnesium
A week 3.26p × 7 = 23p · a month × 30 = 98p · a year × 365 = £11.89
Amount per serving: stated on the label.
