Cognitive function [among other things] is influenced by the availability and metabolism of amino acids. This graphic is meant to highlight the multifaceted roles of specific amino acids in neural pathways. For instance, β-alanine stands as a neuromodulator with affinities for

@drwilliamwallac Eating more or less of any of these amino acids certainly influences plasma levels - but how about brain levels?

The brain requires a constant supply of vitamins and minerals for energy metabolism, antioxidant defense, neurotransmitter synthesis, ion homeostasis, metabolism, and to maintain basal cognitive function. Surprisingly, the science on the impact of nutrition and brain health is
