How we worked it out

Spermidine

  • Servings: 60 ÷ 2 per serving = 30
  • In the pack: 30 × 6 mg = 180 mg
  • £24.99 ÷ 180 mg × 1 mg = 13.9p per 1 mg
  • A week 13.9p × 7 = 97p · a month × 30 = £4.17 · a year × 365 = £50.67
  • Amount per serving: active constituent content stated on the label (or its stated percentage of the extract).

Thiamine (vitamin B1)

  • Servings: 60 ÷ 2 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £24.99 ÷ 1.5 g × 100 mg = £1.67 per 100 mg
  • A week £1.67 × 7 = £11.66 · a month × 30 = £49.98 · a year × 365 = £608.09
  • Amount per serving: stated on the label.

Zinc

  • Servings: 60 ÷ 2 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £24.99 ÷ 1.5 g × 15 mg = 25p per 15 mg zinc
  • A week 25p × 7 = £1.75 · a month × 30 = £7.50 · a year × 365 = £91.21
  • Amount per serving: stated on the label.
