MegaMag® Muscle, Strawberry Lemonade, 150 g

£29.99 for 150 g 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.

A day£2.00
A week£14.00

How we worked it out

Taurine

  • Servings: 150 ÷ 5 per serving = 30
  • In the pack: 30 × 500 mg = 15 g
  • £29.99 ÷ 15 g × 1 g = £2.00 per 1 g
  • A week £2.00 × 7 = £14.00 · a month × 30 = £59.98 · a year × 365 = £729.76
  • Amount per serving: stated on the label.

Calcium

  • Servings: 150 ÷ 5 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £29.99 ÷ 1.5 g × 500 mg = £10.00 per 500 mg calcium
  • A week £10.00 × 7 = £69.98 · a month × 30 = £299.90 · a year × 365 = £3648.78
  • Amount per serving: stated on the label.

Electrolytes

  • Servings: 150 ÷ 5 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.

Niacin (vitamin B3)

  • Servings: 150 ÷ 5 per serving = 30
  • In the pack: 30 × 10 mg = 300 mg
  • £29.99 ÷ 300 mg × 500 mg = £49.98 per 500 mg
  • A week £49.98 × 7 = £349.88 · a month × 30 = £1499.50 · a year × 365 = £18243.92
  • Amount per serving: stated on the label.

Thiamine (vitamin B1)

  • Servings: 150 ÷ 5 per serving = 30
  • In the pack: 30 × 2 mg = 60 mg
  • £29.99 ÷ 60 mg × 100 mg = £49.98 per 100 mg
  • A week £49.98 × 7 = £349.88 · a month × 30 = £1499.50 · a year × 365 = £18243.92
