What it really costs, per 100 mg36pOne 100 mg dose is our comparison unit for phosphatidylserine. It is not a recommendation.
A day36p
A week£2.50
A month£10.73
A year£130.49

At one 100 mg dose a day, this pack lasts 2 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Phosphatidylserine

  • In the pack: 60 × 100 mg = 6 g
  • £21.45 ÷ 6 g × 100 mg = 35.8p per 100 mg
  • A week 35.8p × 7 = £2.50 · a month × 30 = £10.73 · a year × 365 = £130.49
  • Amount per serving: stated on the label.

Choline

  • In the pack: 60 × 100 mg = 6 g
  • £21.45 ÷ 6 g × 250 mg = 89.4p per 250 mg choline
  • A week 89.4p × 7 = £6.26 · a month × 30 = £26.81 · a year × 365 = £326.22
  • Amount per serving: stated on the label.

Inositol

  • In the pack: 60 × 50 mg = 3 g
  • £21.45 ÷ 3 g × 2 g = £14.30 per 2 g
  • A week £14.30 × 7 = £100.10 · a month × 30 = £429.00 · a year × 365 = £5219.50
  • Amount per serving: stated on the label.
