Shaanxi Diaries Biotech Co., Ltd. is a leading high-tech enterprise specializing in the research, development, custom formulation, and global distribution of premium plant extracts, amino acid compounds, and functional active ingredients. Strategically located in Xi’an, Shaanxi Province, China, we operate at the intersection of traditional botanical wisdom and cutting-edge bio-engineering.
In the modern nutrition, pharmaceutical, and cosmeceutical sectors, raw monomolecular amino acids no longer satisfy the complex requirements of downstream formulation development. The global functional food and supplement industries are witnessing an unprecedented shift toward Custom Amino Acid Compounds. These multi-ingredient synergistic matrixes address specific physiological needs—such as cognitive improvement, athletic recovery, sleep enhancement, and dermal rejuvenation—while streamlining manufacturing pipelines for brand owners.
Industrial buyers face persistent challenges when sourcing bulk amino acids: ensuring homogeneous blending, eliminating cross-contamination, masking unpleasant bitter profiles, and enhancing water solubility. Furthermore, downstream applications require meticulous ingredient combinations, such as combining GABA with L-Theanine for neuro-calming properties, or pairing antioxidants like Ergothioneine with targeted peptides to achieve optimal skin-brightening efficacy. By shifting from sourcing individual ingredients to sourcing ready-to-fill, pre-formulated compounds, global enterprises mitigate supply chain complexity, reduce laboratory R&D costs, and secure competitive lead times.
Standard amino acids suffer from poor oral bioavailability. Our custom formulations leverage micro-encapsulation and co-crystallization technologies to improve target absorption rates and physiological efficacy.
Using natural flavor matrices and physical barrier technologies to neutralize the bitter and metallic tastes inherent to raw branched-chain amino acids (BCAAs) and bioactive peptides.
Whether you require spray-dried highly-soluble powders, sustained-release granules, or softgel-ready oil suspensions, we calibrate the compound's particle size to match your exact packaging requirements.
Shaanxi Diaries Biotech Co., Ltd. serves as an expert manufacturing partner across multiple strategic global industries. We design targeted ingredient solutions that address pressing market trends and scientific advancements.
With the rise of mental wellness trends, formulations targeting stress reduction and sleep improvement are in high demand. We formulate specialized blends such as our sleep support solutions combining GABA, L-Theanine, and Hydrolyzed Casein Peptides. These components act synergistically to cross the blood-brain barrier, offering documented relief from chronic sleep disorders without generating pharmaceutical dependency.
Beauty-from-within is no longer just a trend; it is a clinical reality. Our anti-aging formulations combine premium intracellular antioxidants such as 99% Pure Ergothioneine with botanical extracts like Crocetin and advanced whitening agents like Deoxyarbutin. This multi-pathway approach targets cellular oxidative stress and inhibits melanin synthesis, providing comprehensive dermal protection.
To meet the growing demand for plant-based alternatives, we offer 99% Pure Yeast Protein Isolate. This allergen-free, sustainable protein source has a balanced amino acid profile that matches or exceeds whey protein. We customize this protein matrix with functional plant powders and flavor components to produce premium vegan nutritional powders.
As a forward-looking OEM manufacturer, Shaanxi Diaries Biotech invests heavily in biological synthesis, enzymatic transformation, and precision fermentation. Our R&D team works closely with leading academic institutions to pioneer next-generation active ingredients.
Our technological roadmap focuses on transitioning from traditional herbal extraction to green, carbon-neutral manufacturing. By utilizing engineered microbes (yeast and E. coli strains), we can biosynthesize high-purity, complex amino acid derivatives like Ergothioneine and specific therapeutic peptides. This approach ensures 100% molecular consistency, eliminates seasonal supply fluctuations, and significantly reduces the environmental impact of raw material sourcing.
Our modern factory in Xi'an, Shaanxi Province, spans over 70,000 square meters and is equipped with advanced extraction, concentration, and separation equipment. We maintain six standardized plant extraction lines alongside class 100,000 cleanroom purification workshops. This infrastructure allows us to manage projects from initial raw material processing through custom formulation mixing to final automated packaging.
Navigating the global regulatory landscape is a significant challenge for importers of health ingredients. Shaanxi Diaries Biotech maintains a comprehensive quality management system that satisfies strict international standards. Our raw materials, extraction processes, and finished compounds are fully traceable from seed to shelf.
We offer extensive documentation support to facilitate localized customs clearance and regulatory registration, including Certificate of Analysis (COA), Allergen Statements, GMO-Free Declarations, and heavy metal and pesticide residue reports. Our operations are certified under recognized international standards, including:
By maintaining these certifications, we help our partners simplify compliance verification in North America, Europe, Southeast Asia, and the Middle East.
We provide complete customization, including target ingredient ratios, flavor profiles, and color matching. We also offer physical modifications like powder micronization, granulation, and oil dispersion to suit capsules, tablets, softgels, or instant drinks.
Every custom formulation undergoes stress testing, including heat, humidity, and light exposure, at our QC testing center. For highly active or oxygen-sensitive compounds, we apply micro-encapsulation to ensure potency throughout the product's shelf life.
For standard single-ingredient powders, the MOQ is typically 25kg (one drum). For customized compound formulations, OEM private label softgels, or complex nutritional blends, the MOQ generally ranges from 100kg to 500kg depending on the raw materials and processing requirements.
Yes. Alongside our internal COA, we regularly work with independent third-party laboratories such as SGS, Eurofins, and Pony Testing to verify purity, assay values, heavy metals, pesticide residues, and microbial parameters.
