How we worked it out
Zinc
- Servings: 180 ÷ 2 per serving = 90
- In the pack: 90 × 20 mg = 1.8 g
- £19.99 ÷ 1.8 g × 15 mg = 16.7p per 15 mg zinc
- A week 16.7p × 7 = £1.17 · a month × 30 = £5.00 · a year × 365 = £60.80
- Amount per serving: stated on the label.
Magnesium
- Servings: 180 ÷ 2 per serving = 90
- In the pack: 90 × 300 mg = 27 g
- £19.99 ÷ 27 g × 100 mg = 7.4p per 100 mg magnesium
- A week 7.4p × 7 = 52p · a month × 30 = £2.22 · a year × 365 = £27.02
- Amount per serving: stated on the label.
