GLYCINE | Sleep Amino Acid
The Sleep Amino Acid · Collagen Building Block · Glutathione Precursor
The simplest amino acid with the most powerful benefits — clinically proven to improve sleep quality, support collagen synthesis, and boost glutathione production.
What is Glycine?
The foundation of modern sleep and wellness formulations
The Simplest, Most Versatile Amino Acid
Glycine (C₂H₅NO₂) is the smallest and simplest amino acid in the human body. Despite its simplicity, it plays a critical role in over 100 metabolic reactions — from building collagen to producing glutathione, the body's master antioxidant.
Clinical research from Osaka University demonstrates that just 3g of glycine before bed significantly improves sleep quality by lowering core body temperature — a natural, non-habit-forming mechanism that signals the body to enter deep sleep.
As consumers shift away from melatonin toward amino acid-based sleep solutions, glycine is emerging as the preferred ingredient for clean-label sleep supplements.
Core Benefits
Science-backed benefits for modern health formulations
Sleep Enhancement
Lowers core body temperature to signal sleep onset. 3g before bed improves subjective sleep quality and next-day cognitive performance.
Glutathione Precursor
Directly contributes to glutathione synthesis — the body's master antioxidant. Supports detoxification and immune defense.
Collagen Building Block
Makes up ~33% of collagen structure. Essential for skin elasticity, joint health, and connective tissue repair.
Neurotransmitter Support
Inhibitory neurotransmitter that calms the central nervous system. Reduces anxiety and promotes mental clarity.
Metabolic Regulation
Supports glucose metabolism and insulin sensitivity. Research suggests benefits for metabolic syndrome management.
Muscle Recovery
Promotes creatine synthesis and supports muscle repair. Ideal for sports nutrition and post-workout formulations.
