Studies
These studies provide scientific insights into Alpha GPC benefits:
A 2013 randomized, double-blind crossover trial in 20 healthy adults found 600 mg/day alpha-GPC for 6 days increased growth hormone secretion by 44% versus placebo (P < 0.05) and improved reaction time in a memory task (P = 0.04).
No RCTs
have assessed alpha-GPC for long-term cognitive decline or athletic performance in humans.This article was originally published on Stackbb.com, your trusted source for science-based supplement guides.
