Discover our highly purified botanical active ingredients formulated to pharmaceutical, nutraceutical, and cosmaceutical grades.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) is China's premier manufacturer and exporter of standard, custom, and highly refined herbal extracts, pharmaceutical intermediates, and functional lipids such as Oleoylethanolamide (OEA). With an established track record spanning more than 20 years, TRB represents the highest tier of production capability and scientific integration in China's bio-tech landscape.
Our operation seamlessly integrates research and development, pilot-scale synthesis, industrial-scale extraction, and direct global distribution. This fully vertical integration allows us to supply the global market with elite bioactives, food additives, and nutritional raw materials, ensuring total control over purity, heavy metal parameters, pesticide limits, and product stability.
Due to our continuous dedication to optimizing natural active ingredients and providing comprehensive solution support, we are proud to be the recipient of the prestigious 2026 "Global Biotechnology and Life Sciences Award" - ''Best Global Herbal Extract Provider 2026''.
TRB operates three state-of-the-art manufacturing facilities. Our flagship factory specializes in premium herbal extraction and chemical synthesis (including Oleoylethanolamide / OEA); our second plant focuses on high-purity bee products; and our third facility is dedicated to advanced animal-derived extract processing. This diverse structural layout enables us to power global brands across five continents with certified bio-ingredients.
Discover how this endogenous lipid molecule is transforming the global fat-burner and satiety supplement sectors.
OEA is a potent, naturally occurring lipid mediator that regulates food intake and body weight. It acts primarily by binding and activating Peroxisome Proliferator-Activated Receptor Alpha (PPAR-α), which is essential for modulating fatty acid oxidation, lipid metabolism, and homeostatic energy balance.
By activating sensory afferent fibers of the vagus nerve, OEA sends signal cascades to the central nervous system (specifically the hypothalamus and hindbrain), inducing a natural sense of fullness or satiety. This reduces daily calorie intake without causing central nervous system stimulation or jitteriness.
As a clean ingredient, OEA serves as a primary base in modern formulations. B2B buyers pair OEA with metabolic boosters (such as Hawthorn Extract or Cassia Nomame) and cognitive agents (like Alpha GPC) to formulate comprehensive body composition solutions.
Unlocking technological supremacy, vertical supply chain integration, and rigorous global compliance.
Our OEA (Oleoylethanolamide) is manufactured using modern condensation and crystallization methods. By carefully maintaining temperature, pressure, and solvent ratios, we yield OEA powder with an HPLC purity of ≥98% and extremely low residual solvents, matching strict USP and EU Pharmacopoeia guidelines.
Our laboratories are equipped with Ultra-Performance Liquid Chromatography (UPLC), Gas Chromatography-Mass Spectrometry (GC-MS), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This ensures that every batch of OEA has zero contamination, verified heavy metal parameters (Pb < 1ppm, As < 1ppm), and compliant microbiological assays.
With an annual production capacity of hundreds of metric tons across our 3 factories, TRB leverages scale economies. Our direct raw material procurement contracts and optimized industrial synthesis pathways significantly lower production costs compared to Western alternatives, passing the savings to our partners.
How our enterprise clients across the USA, EU, and APAC leverage TRB ingredients in their regional markets.
By blending OEA with Hoodia Gordonii Extract and Cassia Nomame Extract, brands create dual-action fat burners that simultaneously suppress appetite and inhibit lipase activity, offering a dual metabolic pathway approach.
We supply Alpha GPC Powder 99% and OEA as a stack for sports nutrition. While OEA aids cellular fat mobilization and metabolic focus, Alpha GPC optimizes acetylcholine levels, enhancing cognitive power and physical focus.
In the EU market, combining OEA with Hawthorn Leaf Extract or Vitis Vinifera Extract has gained significant traction. This synergy promotes arterial flexibility, healthy circulation, and natural fat utilization.
TRB's facility processes are certified by the world's most demanding auditing bodies to ensure zero-risk global logistics.
For pharmaceutical and high-end nutraceutical brands in the US and Europe, we provide comprehensive technical packages, including Drug Master Files (DMF) support, COA (Certificate of Analysis) for every batch, MSDS, Allergen Statements, and heavy metals declarations. This transparent documentation guarantees seamless FDA clearances and simplifies product registration processes.
In accordance with global ESG mandates, TRB utilizes clean extraction technologies. We minimize carbon emissions through efficient water circulation systems, non-toxic organic solvents, and eco-friendly synthetic pathways. Our commitment guarantees that your brand's supply chain remains ethically sound and environmentally responsible.
