How we worked it out

Electrolytes

  • In the pack: 30 × 1 serving = 30 servings
  • £28.49 ÷ 30 servings × 1 serving = 95p per serving
  • A week 95p × 7 = £6.65 · a month × 30 = £28.49 · a year × 365 = £346.63
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • In the pack: 30 × 125 mg = 3.75 g
  • £28.49 ÷ 3.75 g × 100 mg = 76p per 100 mg magnesium
  • A week 76p × 7 = £5.32 · a month × 30 = £22.79 · a year × 365 = £277.30
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • In the pack: 30 × 25 mg = 750 mg
  • £28.49 ÷ 750 mg × 500 mg = £18.99 per 500 mg
  • A week £18.99 × 7 = £132.95 · a month × 30 = £569.80 · a year × 365 = £6932.57
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 30 × 500 mg = 15 g
  • £28.49 ÷ 15 g × 200 mg = 38p per 200 mg potassium
  • A week 38p × 7 = £2.66 · a month × 30 = £11.40 · a year × 365 = £138.65
  • Amount per serving: stated on the label.
