Glycine activates NMDA receptors in the suprachiasmatic nucleus (SCN), the brain region that serves as the master circadian clock
Importantly, the protein itself is only one component of a broader separation system
In this regard, it can be noted that transcription of the gdhA gene initiates from two promoters, one weak, constitutively expressed, called gdhA P1, and another, more potent, called gdhA P2, transactivated by GdhR, a transcriptional regulator whose DNA binding is inhibited by -ketoglutarate (Pagliarulo et al., 2004)
It helps identify the minimum effective dose and the point at which efficacy plateaus or side effects become intolerable
Why Patients Are Concerned These drugs are not optional supplements
