How it works

Supports methylation and cellular hydration, indirectly influencing brain function and energy balance.

Overview

Betaine plays a key role in methylation, a process essential for DNA expression, neurotransmitter synthesis, and overall cellular health. While it is more commonly associated with physical performance and liver function, its indirect effects on brain health make it relevant in cognitive optimisation. It does not produce immediate nootropic effects but contributes to long-term neurological efficiency and resilience.
