Unlike sedative-hypnotics that suppress REM sleep and create dependency, DSIP appears to support natural sleep architecture allowing normal progression through all sleep stages while specifically enhancing the deepest, most restorative phases
In a double-blind, randomized, placebo-controlled study, Ahmad et al 305 showed significant improvement over time in postdialysis asthenia in both L-carnitine-and placebo-treated patients
