Recommended Usage & Formulation Guidance for Glycine
Proper incorporation of glycine ensures optimal functionality and stability in finished products. Below are detailed guidelines; specific formulations should be developed with technical support from our team.
In Food Industry Applications
For flavor enhancement in beverages: Dissolve glycine in water phase at 0.1%-0.2%. For meat preservation: Apply as part of marinade or coating at 0.2%-0.3%. Glycine is highly soluble in water (approximately 25g/100mL at 25°C) and stable under normal food processing conditions.
In Pharmaceutical Formulations
For injectable solutions: Use pharmaceutical-grade glycine with strict endotoxin controls. Typical concentrations in IV solutions: 1.5%-2.5% for irrigation solutions, higher for specialized formulations. Ensure compliance with regional pharmacopeial standards and sterilization requirements.
In Cosmetic Products
Incorporate into water phase of formulations at 0.5%-2.0%. For leave-on products, consider combination with other amino acids for synergistic effects. Glycine is compatible with most cosmetic ingredients and stable across typical pH ranges of cosmetic products (4.0-8.0).

As a leading l-glycine supplier, we offer bulk glycine powder for manufacturers worldwide. You can purchase directly from our company for quantities ranging from 25 kg bags to full container loads. We provide competitive pricing for volume orders and customized packaging options to meet your specific requirements.
Glycine is the simplest amino acid and does not have chiral centers, meaning it doesn’t have D- or L- isomers like other amino acids. Therefore, glycine and L-glycine refer to the same compound. Some suppliers use “L-glycine” to indicate the natural form, but chemically, there is no distinction as there is with other amino acids.
Glycine serves multiple functions in food applications: as a flavor enhancer (masking bitterness and enhancing sweetness), preservative (extending shelf life of meats and seafood), pH buffer, and antioxidant synergist. Typical usage ranges from 0.1% to 0.3% depending on the specific application and regulatory guidelines in target markets.
When selecting a glycine supplier, consider these key factors: quality certifications (ISO, GMP, Kosher, Halal), purity specifications (≥99%), production capacity, technical support capabilities, regulatory compliance for your target markets, and supply chain reliability.
