Identity and synonyms
Catalog label is recorded; analytical identity and equivalence are not established.
Nonpeptide agent · Amino acid or derivative
Detailed molecular class: Nonpeptide agent; see mechanism for subtype
Supplied sequence or chemical reference
PubChem CID: 6137
Molecular formula: C5H11NO2S
IUPAC: (2S)-2-amino-4-methylsulfanylbutanoic acid
Source: PC-METHIONINE
Database chemical reference; does not certify supplier vial, salt, isomer or formulation.
Mechanism
Essential amino acid, S-adenosylmethionine precursor and participant in one-carbon metabolism.
Evidence and critical reading
Reported scientific and empirical uses
Replacement and nutritional context
MIC/Lipo-C ingredient under a “lipotropic” narrative; methionine is neither SAMe nor a standardized MIC blend.
Human evidence
Nutritional function does not establish fat loss from parenteral methionine or blend synergy. No human regimen was assigned for that aim.
Preclinical evidence
Do not equate mechanism, cell culture or animal work with a clinical outcome. The specific level is detailed in the evidence assessment.
Critical reading and limitations
Nutritional function does not establish fat loss from parenteral methionine or blend synergy. No human regimen was assigned for that aim.
Nutritional function does not establish fat loss from parenteral methionine or blend synergy. No human regimen was assigned for that aim.
Source-specific regimens
Descriptive source observations, not individual recommendations.
Regulatory product labeling
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Human-study exposure
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Empirical handbook
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Regulation and safety
Jurisdiction-specific regulatory context
This record does not verify FDA/EMA authorization of the commercial identity. Where a specific medicine/product exists, jurisdiction/indication are detailed in cited sources; they do not transfer to supplier material.
Adverse effects and unknowns
Homocysteine metabolism and folate/B12 status matter. An essential nutrient is not harmless at every dose/route.
Contraindications
A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.
Interactions
Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.
Studies and trials
Selected studies
No selected studies are attributed in this record.
Trials attributed in the package
No trials are attributed in this record.
Trial registration does not establish efficacy or validate commercial material.
