How we worked it out

Omega-3

  • In the pack: 90 × 209 mg = 18.8 g
  • £23.49 ÷ 18.8 g × 1 g = £1.25 per 1 g EPA + DHA
  • A week £1.25 × 7 = £8.74 · a month × 30 = £37.46 · a year × 365 = £455.81
  • Amount per serving: added up from the components stated on the label.

Astaxanthin

  • In the pack: 90 × 0.12 mg = 10.8 mg
  • £23.49 ÷ 10.8 mg × 4 mg = £8.70 per 4 mg
  • A week £8.70 × 7 = £60.90 · a month × 30 = £261.00 · a year × 365 = £3175.50
  • Amount per serving: stated on the label.

Choline

  • In the pack: 90 × 0.06 mg = 5.4 mg
  • £23.49 ÷ 5.4 mg × 250 mg = £1087.50 per 250 mg choline
  • A week £1087.50 × 7 = £7612.50 · a month × 30 = £32625.00 · a year × 365 = £396937.50
