L-Glycine is a naturally sweet-tasting amino acid that may be the next great natural sleep aid nutrient.* L-Glycine is ubiquitous in the human body and serves a critical role in the central nervous system (where it acts as an inhibitory neurotransmitter… calming overactive brain neurons).* Studies show that a single nighttime dose of 3,000 mg (3 g) of L-Glycine can help ameliorate the “next day” symptoms of sleep deprivation – improving overall sleep satisfaction and decreasing daytime sleepiness and cognitive impairment.*

Rather than giving you an excessively large dose of melatonin (3 mg or higher), we opted for a micro-dose of melatonin (0.3 mg) instead. This super small quantity replicates the amount normally produced by the body each night: 0.075-0.3 mg. It’s notable that 3 mg of melatonin (which is considered the norm in retail stores) is somewhere between 10-40x higher than the normal physiological quantity. Therefore, 3 mg of melatonin may be considered a “pharmacological dose” due to its size and drug-like effect: heavy sedation. Here at Youtheory, we believe that individuals should refrain from using a “pharmacological dose” for more than three consecutive nights (as a rule of thumb) and instead opt for a more natural sleep aid
