How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
A
Strong
Multiple RCTs, consistent direction, adequate effect size
B
Moderate
Some RCTs or consistent observational data in humans
C
Preliminary / Mixed
Animal or in-vitro only, or conflicting human data
D
Traditional / Theoretical
Traditional use only; no controlled human trials

Compound profile context
How to interpret Glutamine
Glutamine dosage by use case, onset and duration, safety limits, and interactions for gut epithelium, graded against research. Mechanistic Evidence research… Use this compound profile to understand mechanism, evidence quality, and practical safety context before comparing products or building a stack. A biochemical pathway connection can be useful for discovery, but it is not the same as proven benefit in humans.
When reviewing Glutamine, separate the active molecule from the product category around it. Dose form, absorption, extract standardization, medication interactions, and individual sensitivity can change the real-world risk-benefit picture.
For supplement planning, avoid combining multiple compounds with overlapping sedating, stimulating, serotonergic, blood-pressure, anticoagulant, or liver-metabolism effects unless a qualified clinician has reviewed the context.
