Q

What does the research say about the effectiveness of oral GABA supplementation?

A

Research, including a 2019 review in Frontiers in Neuroscience, indicates that while high doses of oral GABA can reduce alpha brain wave activity, the effects are inconsistent and substantially weaker than those achieved through endogenous GABA modulation. This suggests that oral GABA primarily acts on the peripheral nervous system rather than directly impacting the central nervous system.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
