Glutamate accumulation to micromolar levels [375] results in GluN2B-mediated NMDA receptor overactivation, Ca 2+ overload, and subsequent tau hyperphosphorylation and dendritic spine collapse [376], linking excitotoxicity to amyloidogenesis [28]
This is not completely clear so it cannot be concluded that higher levels of glycine induces a higher response
The Bigger Concern: Appetite Suppression During Lactation While medication transfer appears minimal, GLP-1 medications are designed to reduce appetite and slow digestion
That is why a targeted approach to protein, nutrient-dense foods, and the right supplements can make such a meaningful difference while on GLP-1
Oral bioavailability differs significantly from subcutaneous delivery, which means the degree of prior receptor adaptation is not directly comparable
