£46.49 for 25 servings at Healf. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.

What it really costs, per 50 g£4.65One 50 g dose is our comparison unit for carbohydrate powders. It is not a recommendation.
A day£4.65
A week£32.54
A month£139.47
A year£1696.89

At one 50 g dose a day, this pack lasts 10 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Carbohydrate powders

  • In the pack: 25 × 20 g = 500 g
  • £46.49 ÷ 500 g × 50 g = £4.65 per 50 g
  • A week £4.65 × 7 = £32.54 · a month × 30 = £139.47 · a year × 365 = £1696.89
  • Amount per serving: stated on the label.

Calcium

  • In the pack: 25 × 50 mg = 1.25 g
  • £46.49 ÷ 1.25 g × 500 mg = £18.60 per 500 mg calcium
  • A week £18.60 × 7 = £130.17 · a month × 30 = £557.88 · a year × 365 = £6787.54
  • Amount per serving: stated on the label.

Electrolytes

  • In the pack: 25 × 1 serving = 25 servings
  • £46.49 ÷ 25 servings × 1 serving = £1.86 per serving
  • A week £1.86 × 7 = £13.02 · a month × 30 = £55.79 · a year × 365 = £678.75
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • In the pack: 25 × 10 mg = 250 mg
  • £46.49 ÷ 250 mg × 100 mg = £18.60 per 100 mg magnesium

  • Amount per serving: stated on the label.

Potassium

  • In the pack: 25 × 60 mg = 1.5 g
  • £46.49 ÷ 1.5 g × 200 mg = £6.20 per 200 mg potassium
  • A week £6.20 × 7 = £43.39 · a month × 30 = £185.96 · a year × 365 = £2262.51
