Amino Acid
L-Alanine
Also known as: alanine, beta-alanine precursor, L-α-alanine
L-alanine is a non-essential amino acid involved in protein synthesis and glucose metabolism via the alanine cycle. Evidence for performance or cognitive benefits is limited and primarily theoretical.
Primary uses
- Protein synthesis support
- Glucose metabolism
- Exercise recovery
How it works
- Serves as a building block for protein synthesis
- Participates in the alanine cycle for glucose production during exercise
- Supports cellular energy metabolism
Dosage
- Typical range
- 1-5 g daily
- Timing
- Can be taken any time; no critical timing window
- With food
- Can be taken with or without food
- Duration
- No established optimal duration; safe for long-term use as part of normal diet
- Special populations
- No specific contraindications in healthy adults
Forms
- powder· 70/100
- capsule· 70/100
Safety
Evidence notes
L-alanine is an endogenous amino acid with established biochemical roles, but direct supplementation lacks robust clinical evidence for performance or health benefits in healthy populations. Most studies focus on beta-alanine (a different compound) rather than L-alanine itself.
Grade D: Primarily pre-clinical or anecdotal; human efficacy not established.
