How we worked it out
Zinc
- Servings: 60 ÷ 2 per serving = 30
- In the pack: 30 × 20 mg = 600 mg
- £7.99 ÷ 600 mg × 15 mg = 20p per 15 mg zinc
- A week 20p × 7 = £1.40 · a month × 30 = £5.99 · a year × 365 = £72.91
- Amount per serving: stated on the label.
Magnesium
- Servings: 60 ÷ 2 per serving = 30
- In the pack: 30 × 300 mg = 9 g
- £7.99 ÷ 9 g × 100 mg = 8.88p per 100 mg magnesium
- A week 8.88p × 7 = 62p · a month × 30 = £2.66 · a year × 365 = £32.40
- Amount per serving: stated on the label.
