How we worked it out

Ashwagandha

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 550 mg = 49.5 g
  • £19.99 ÷ 49.5 g × 600 mg = 24.2p per 600 mg
  • A week 24.2p × 7 = £1.70 · a month × 30 = £7.27 · a year × 365 = £88.44
  • Amount per serving: extract weight stated on the label.

Black pepper (piperine)

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 5 mg = 450 mg
  • £19.99 ÷ 450 mg × 5 mg = 22.2p per 5 mg
  • A week 22.2p × 7 = £1.55 · a month × 30 = £6.66 · a year × 365 = £81.07
  • Amount per serving: extract weight stated on the label.
