How we worked it out

Electrolytes

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 1 serving = 30 servings
  • £29.99 ÷ 30 servings × 1 serving = £1.00 per serving
  • A week £1.00 × 7 = £7.00 · a month × 30 = £29.99 · a year × 365 = £364.88
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 20 mg = 600 mg
  • £29.99 ÷ 600 mg × 500 mg = £24.99 per 500 mg calcium
  • A week £24.99 × 7 = £174.94 · a month × 30 = £749.75 · a year × 365 = £9121.96
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 100 mg = 3 g
  • £29.99 ÷ 3 g × 100 mg = £1.00 per 100 mg magnesium
  • A week £1.00 × 7 = £7.00 · a month × 30 = £29.99 · a year × 365 = £364.88
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 25 mg = 750 mg
  • £29.99 ÷ 750 mg × 500 mg = £19.99 per 500 mg
  • A week £19.99 × 7 = £139.95 · a month × 30 = £599.80 · a year × 365 = £7297.57
  • Amount per serving: stated on the label.

Potassium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 250 mg = 7.5 g
  • £29.99 ÷ 7.5 g × 200 mg = 80p per 200 mg potassium
  • A week 80p × 7 = £5.60 · a month × 30 = £23.99 · a year × 365 = £291.90
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 80 mg = 2.4 g
  • £29.99 ÷ 2.4 g × 1 g = £12.50 per 1 g
  • A week £12.50 × 7 = £87.47 · a month × 30 = £374.88 · a year × 365 = £4560.98
  • Amount per serving: stated on the label.
