How we worked it out

Milk thistle

  • Servings: 200 ÷ 1 per serving = 200
  • In the pack: 200 × 240 mg = 48 g
  • £25.59 ÷ 48 g × 150 mg = 8p per 150 mg
  • A week 8p × 7 = 56p · a month × 30 = £2.40 · a year × 365 = £29.19
  • Amount per serving: active constituent content stated on the label (or its stated percentage of the extract).

Dandelion

  • Servings: 200 ÷ 1 per serving = 200
  • In the pack: 200 × 100 mg = 20 g
  • £25.59 ÷ 20 g × 500 mg = 64p per 500 mg
  • A week 64p × 7 = £4.48 · a month × 30 = £19.19 · a year × 365 = £233.51
  • Amount per serving: extract weight stated on the label.
