GlyceroPhosphoCholine 300mg 60caps by Designs for Health.

To better reflect the dosages that were used in most clinical studies (600-1200 mg per day), GlyceroPhosphoCholine (GPC) has been reformulated to a 300 mg per capsule dosage, and is now available in a 60 count size (which yields 33% more GPC per bottle than the previous GPC product).

GPC (GlyceroPhosphoCholine) is a protective orthomolecular nutri­ent for the brain, kidneys, muscles, testes and other organs, and a water-phase building block for cell membrane phospholipids. GPC is proven through randomized controlled trials as highly effective for brain circulatory insufficiency and recovery from ischemic damage or other trauma.

When used at the higher therapeutic ranges of 600-1200 mg per day, this will be a 15-30 day supply. The maintenance dosage with GPC is 300-600 mg per day, which translates to a 30-60 day supply.
