Allo-Inositol is a rare stereoisomer of inositol, primarily utilized in advanced scientific research for its unique biochemical properties. It is studied for its potential as a lithium mimetic in the treatment of bipolar disorder and other mood disorders, due to its ability to modulate inositol monophosphatase activity and influence phosphoinositide signaling pathways. Research also explores its roles in neuroprotection, cellular signaling, and metabolic regulation, including effects on insulin sensitivity and glucose metabolism. Unlike more common inositols like myo-inositol, allo-inositol's niche applications extend to specialized dietary supplements and pharmaceutical development targeting neurological and psychiatric conditions.
