Kids Calm Mind, 30 tablets

£29.50 for 30 tablets 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£1.40One 100 mg dose is our comparison unit for magnesium. It is not a recommendation.
A day£1.40
A week£9.83
A month£42.14
A year£512.74

At one 100 mg dose a day, this pack lasts 21 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Magnesium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 70 mg = 2.1 g
  • £29.50 ÷ 2.1 g × 100 mg = £1.40 per 100 mg magnesium
  • A week £1.40 × 7 = £9.83 · a month × 30 = £42.14 · a year × 365 = £512.74
  • Amount per serving: stated on the label.

Saffron extract

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 15 mg = 450 mg
  • £29.50 ÷ 450 mg × 30 mg = £1.97 per 30 mg
  • A week £1.97 × 7 = £13.77 · a month × 30 = £59.00 · a year × 365 = £717.83
  • Amount per serving: extract weight stated on the label.

Vitamin B6

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 0.5 mg = 15 mg
  • £29.50 ÷ 15 mg × 50 mg = £98.33 per 50 mg
  • A week £98.33 × 7 = £688.33 · a month × 30 = £2950.00 · a year × 365 = £35891.67
  • Amount per serving: stated on the label.

Zinc

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 5 mg = 150 mg
  • £29.50 ÷ 150 mg × 15 mg = £2.95 per 15 mg zinc
  • A week £2.95 × 7 = £20.65 · a month × 30 = £88.50 · a year × 365 = £1076.75
  • Amount per serving: stated on the label.
