Hydrate - Lemon Lime - 40 serv

£30.99 for 40 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 100 mg magnesium£1.55One 100 mg dose is our comparison unit for magnesium. It is not a recommendation.
A day£1.55
A week£10.85
A month£46.49
A year£565.57

At one 100 mg dose a day, this pack lasts 20 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Magnesium

  • In the pack: 40 × 50 mg = 2 g
  • £30.99 ÷ 2 g × 100 mg = £1.55 per 100 mg magnesium
  • A week £1.55 × 7 = £10.85 · a month × 30 = £46.49 · a year × 365 = £565.57
  • Amount per serving: stated on the label.

Calcium

  • In the pack: 40 × 84 mg = 3.36 g
  • £30.99 ÷ 3.36 g × 500 mg = £4.61 per 500 mg calcium
  • A week £4.61 × 7 = £32.28 · a month × 30 = £138.35 · a year × 365 = £1683.24
  • Amount per serving: stated on the label.

Electrolytes

  • In the pack: 40 × 1 serving = 40 servings
  • £30.99 ÷ 40 servings × 1 serving = 77.5p per serving
  • A week 77.5p × 7 = £5.42 · a month × 30 = £23.24 · a year × 365 = £282.78
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Iron

  • In the pack: 40 × 1 mg = 40 mg
  • £30.99 ÷ 40 mg × 14 mg = £10.85 per 14 mg iron
  • A week £10.85 × 7 = £75.93 · a month × 30 = £325.40 · a year × 365 = £3958.97
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 40 × 250 mg = 10 g
  • £30.99 ÷ 10 g × 200 mg = 62p per 200 mg potassium
  • A week 62p × 7 = £4.34 · a month × 30 = £18.59 · a year × 365 = £226.23
  • Amount per serving: stated on the label.

Taurine

  • In the pack: 40 × 1 g = 40 g
  • £30.99 ÷ 40 g × 1 g = 77.5p per 1 g
