How we worked it out
Electrolytes
- Servings: 30 ÷ 1 per serving = 30
- In the pack: 30 × 1 serving = 30 servings
- £34.99 ÷ 30 servings × 1 serving = £1.17 per serving
- A week £1.17 × 7 = £8.16 · a month × 30 = £34.99 · a year × 365 = £425.71
- Amount per serving: priced per serving — compare what each serving contains before choosing.
Magnesium
- Servings: 30 ÷ 1 per serving = 30
- In the pack: 30 × 20 mg = 600 mg
- £34.99 ÷ 600 mg × 100 mg = £5.83 per 100 mg magnesium
- A week £5.83 × 7 = £40.82 · a month × 30 = £174.95 · a year × 365 = £2128.56
- Amount per serving: stated on the label.
Potassium
- Servings: 30 ÷ 1 per serving = 30
- In the pack: 30 × 200 mg = 6 g
- £34.99 ÷ 6 g × 200 mg = £1.17 per 200 mg potassium
- A week £1.17 × 7 = £8.16 · a month × 30 = £34.99 · a year × 365 = £425.71
- Amount per serving: stated on the label.
