At one 1 g dose a day, this pack lasts 11 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

  • Servings: 320 ÷ 1 per serving = 320
  • In the pack: 320 × 1 g = 320 g
  • £20.99 ÷ 320 g × 1 g = 6.56p per 1 g
  • A week 6.56p × 7 = 46p · a month × 30 = £1.97 · a year × 365 = £23.94
  • Amount per serving: stated on the label.

The standard dose is a comparison unit, not a recommendation. Always confirm the price on the retailer's site. How we compare everything.
