Amino Acids
Free-form amino acids and derivatives serve as neurotransmitter precursors, antioxidant builders, and signaling molecules. Timing — fasted, pre-workout, pre-sleep — often matters as much as dose.

Clinical lens
A clinical lens on amino acids supplements
Amino acids are the protein-layer levers — useful for athletes, recovery, and specific neurotransmitter targets.
Use this lane for muscle protein synthesis, sleep architecture, or precise neurotransmitter support.
Best used for
- →Recovery and muscle protein synthesis
- →Pre-bed glycine for sleep
- →Tyrosine for stress-context cognition
- →Taurine for cardiovascular and sleep support
Signal map
- Whole-protein still beats most isolated AAs
- Timing matters for some, not all
- Quality varies more than label suggests
- Single-AA megadose is rarely smart
Decision questions
- Am I covering protein basics first?
- Is the AA solving a measurable problem?
- Could I get this from food cheaper?
Key benefits
- •Neurotransmitter precursor support
- •Glutathione production and detox
- •Muscle protein synthesis and power output
- •Sleep depth and calm
Key considerations
- •Compete with each other for transport
- •Can interact with SSRIs and MAOIs
- •Timing relative to meals matters
Ideal for
Mood and anxiety support
Strength and power athletes
Sleep and stress recovery
