How we worked it out

Spermidine

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 5 mg = 300 mg
  • £40.80 ÷ 300 mg × 1 mg = 13.6p per 1 mg
  • A week 13.6p × 7 = 95p · a month × 30 = £4.08 · a year × 365 = £49.64
  • Amount per serving: active constituent content stated on the label (or its stated percentage of the extract).

Astaxanthin

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 4 mg = 240 mg
  • £40.80 ÷ 240 mg × 4 mg = 68p per 4 mg
  • A week 68p × 7 = £4.76 · a month × 30 = £20.40 · a year × 365 = £248.20
  • Amount per serving: stated on the label.
