L-Proline Powder - Premium Amino Acid Supplement for Pharmaceutical and Nutraceutical Applications
Xi'an Jiayuan Bio-tech Co., Ltd., established in April 2002 with a registered capital of RMB 30 million, specializes in producing high-purity L-Proline Powder that meets international pharmaceutical standards. Our plant has two GMP-certified manufacturing lines and employs 30 skilled technical staff for quality monitoring. Our product conforms to USP/EP/CP, with assay purity of ≥98% and is a vital raw material for collagen synthesis support, wound healing formulations and advanced sports nutrition products. Supported by ISO, SGS and HALAL certifications, we promise you pharmaceutical-grade amino acids for the most demanding applications.
What Is L-Proline Powder?
The result is a white crystalline amino acid with chemical formula C5H9NO2 and molecular weight 115.13. The side chain of proline links back to the backbone nitrogen, a unique cyclic structure that gives outstanding structural stiffness not seen in other amino acids.
This particular feature is essential for collagen synthesis. You have around 15% collagen in your body, which is made up of proline residues. The crystalline powder form provides the best solubility and bioavailability in medicinal compositions.
We hold CAS number 147-85-3 to stringent standards of purity in our goods. It offers a reliable constant quality for demanding applications needing pharmaceutical grade chemicals.

Functions
Proline’s unusual cyclic structure gives it several biological functions:
Promoting Collagen Production: Proline is an important building ingredient for the formation of collagen. Your formulas benefit from its function in stabilising the collagen triple helix structure, which is crucial to skin, cartilage and connective tissue integrity.
Promotes Wound Healing: It aids in tissue regeneration by providing substrates for fibroblast activation. This makes it useful in the post-surgical recovery supplements and for use in dermatology.
Protein Folding and Stability: The tight ring shape is important for protein folding and stability. It is especially beneficial in the formulation of heat-stable nutritional supplements.
Antioxidant Support: Proline contributes to the cellular response to stress, providing protective advantages in sophisticated nutraceutical formulations.
Application Fields
High-purity powder may be utilised in product development in several industries:
Pharmaceutical Industry: Used in wound healing, post-operative recovery, and tissue regeneration medications that need pharmaceutical-grade chemicals.
Sports Nutrition: Create collagen-boosting beverages, joint health supplements, and muscle recovery solutions for athletes.
Cosmeceuticals: Create anti-aging skincare supplements, internal beauty products, and dermatological remedies for skin elasticity and hydration.
Functional Foods: Create amino acid-specific protein beverages, health bars, and meal replacements.
