Glycyl-L-tyrosine is a chemical compound with the molecular formula C₁₁H₁₄N₂O₄ and a molecular weight of 238.2399. Currently, there is no detailed research data on its acute toxicity, skin irritation or corrosion, eye irritation or corrosion, or respiratory or skin sensitization. However, based on its use as a nutritional supplement, glycyl-l-tyrosine appears to exhibit no significant toxic effects when used at appropriate doses.
Glycyl-L-tyrosine is a synthetically produced dipeptide that is rapidly metabolized into tyrosine in the human body. Tyrosine is a non-essential amino acid, but under certain conditions (e.g., in newborns or patients with liver failure), it becomes an essential amino acid.
Glycyl-L-tyrosine and its metabolite, tyrosine, are involved in various biochemical processes in the human body, such as the synthesis of neurotransmitters like melatonin, serotonin, and gamma-aminobutyric acid (GABA). These substances play essential roles in human physiological functions.
As a nutritional supplement, glycyl-L-tyrosine has been widely used to improve sleep quality. Its safety and tolerability have been confirmed in numerous studies. When used at appropriate doses, glycyl-L-tyrosine has minimal side effects and can help individuals achieve better sleep and enhance sleep quality.
Although glycyl-L-tyrosine is relatively safe when used within recommended doses, excessive intake may lead to discomfort or potential health risks. Therefore, it is important to adhere to the recommended dosage. For specific populations, such as pregnant or breastfeeding women and children, it is advisable to consult a doctor or healthcare professional before use.
For storage and transportation, glycyl-L-tyrosine should ideally be kept at -20°C to maintain its stability and safety. Exposure to high temperatures, humidity, and direct sunlight should be avoided to prevent degradation or loss of efficacy.
In conclusion, glycyl-L-tyrosine is relatively safe when used at appropriate doses and has been widely applied in improving sleep quality. However, to ensure its safety and effectiveness, it is important to follow the recommended dosage and proper storage and transportation conditions. For specific populations, consulting a healthcare professional before use is highly recommended.
