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. Due to this, it is neuroprotective to further increase brain health.
GPC is proven through randomized controlled trials as highly effective for brain circulatory insufficiency and recovery from ischemic damage or other trauma. It is also shown to increase brain speed and memory in normal and mildly impaired subjects. And amazingly enough the doses for the brain are the same for muscle and fitness increases in human growth hormone!
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.
