Pharmaceutical-Grade Curcuma Root Extract (Curcumin)
Manufactured by Xi'an Tihealth Biotechnology Co., Ltd.
Xi'an Tihealth is a premier global B2B supplier of highly purified Curcuma Root Extract (Curcuma longa L.). Moving far beyond ordinary turmeric powder or low-yield extracts, we source premium Indian and Chinese turmeric rhizomes to guarantee a fundamentally superior phytochemical matrix, completely free from synthetic dyes and heavy metal contamination.
Utilizing advanced solvent extraction and rigorous crystallization protocols, we successfully isolate and concentrate the root's core therapeutic complex: Curcuminoids (comprising Curcumin, Demethoxycurcumin, and Bisdemethoxycurcumin). Standardized to a pharmaceutical-grade purity of ≥95% via HPLC, our vibrant orange-yellow powder provides an exceptionally potent foundation for downstream formulation. Designed to address the inherent bioavailability challenges of curcumin, our extract serves as the ultimate Active Pharmaceutical Ingredient (API) for joint-health nutraceuticals, advanced anti-inflammatory capsules, and high-end antioxidant skincare.

Manufacturing & Processing Excellence
Ultra-High Purity Crystallization
Crude turmeric powders offer very low active concentrations (typically 2-5%). Tihealth utilizes an advanced solvent extraction followed by rigorous multi-stage crystallization. This eliminates inert plant resins and volatile oils, allowing us to guarantee a standardized ≥95% total curcuminoid complex, significantly reducing the dosage required for end-formulations.
Bioavailability Engineering Base
Curcumin is notoriously poorly absorbed by the human body due to rapid hepatic metabolism and low water solubility. Our high-purity powder acts as the perfect pristine base for formulators utilizing Piperine (black pepper extract) synergy, liposomal encapsulation, or phytosome technologies to exponentially boost clinical absorption rates.
Zero Synthetic Dyes & Toxicity
The global turmeric supply chain is frequently plagued by adulteration with toxic synthetic dyes (like Lead Chromate) to enhance color. Operating under cGMP standards, our facility strictly screens all raw materials and utilizes only food-grade extraction solvents. Residual solvents remain undetectable, ensuring absolute pharmaceutical safety.
Evidence-Based Pharmacological Mechanisms
Broad-Spectrum Anti-Inflammatory Modulation
Curcumin is a master regulator of inflammation. It actively inhibits the NF-κB signaling pathway and suppresses pro-inflammatory enzymes such as COX-2 and LOX. This makes it exceptionally effective as an adjuvant therapy for chronic inflammatory conditions, particularly osteoarthritis and rheumatoid arthritis.
Profound Cellular Antioxidant Defense
The curcuminoid complex possesses a dual antioxidant capability: it directly neutralizes reactive oxygen species (free radicals) while simultaneously stimulating the body's endogenous antioxidant enzymes (like glutathione). This robust defense protects cellular DNA from oxidative degradation and aging.
Neuroprotection & Cognitive Support
Clinical literature suggests curcumin can cross the blood-brain barrier. It actively promotes the synthesis of Brain-Derived Neurotrophic Factor (BDNF) and aids in the clearance of amyloid-beta plaques, presenting significant potential in supporting cognitive longevity and mitigating neurodegenerative decline.
Metabolic Regulation (Lipids & Glucose)
Exhibits potent metabolic balancing effects. Curcumin assists in lowering serum triglyceride levels, improving insulin sensitivity, and reducing endothelial dysfunction, functioning as a valuable nutritional intervention for managing metabolic syndrome and type 2 diabetes progression.
Industrial Formulation Applications
Joint Health Nutraceuticals
The premier Active Pharmaceutical Ingredient (API) for formulating targeted anti-inflammatory capsules, arthritis-relief tablets, and athletic mobility recovery supplements.
Pharmaceutical R&D
Extensively utilized in clinical research as a highly standardized intermediate for developing adjuvant oncological therapies and neuroprotective medications.
Cosmeceuticals & Anti-Aging
Due to its potent antioxidant capacity, it is increasingly incorporated into high-end "beauty-from-within" oral supplements and topical skin-brightening serums.
Functional Foods & Natural Colorants
Serves as a dual-purpose additive: providing significant metabolic health benefits while acting as a remarkably stable, natural yellow-orange colorant for the food industry.

Formulator & Procurement FAQ
01. How do you solve the low bioavailability issue of standard Curcumin?
Our ≥95% extract provides the optimal high-purity baseline. From there, we strongly recommend formulators utilize synergistic additives (such as Piperine/Black Pepper Extract) or employ advanced liposomal/phytosome encapsulation technologies during their manufacturing process to dramatically increase systemic absorption.
02. Is this powder completely water-soluble for clear beverage applications?
No. Natural high-purity curcumin is highly lipophilic (fat-soluble) and practically insoluble in water. If you require a water-soluble variant for functional RTD beverages, please contact our OEM team to discuss our specialized micro-emulsified formulations.
03. Can you guarantee the exact 95% purity from batch to batch?
Absolutely. We do not rely on crude gravimetric ratios. We utilize High-Performance Liquid Chromatography (HPLC) paired with certified reference standards to precisely quantify the total Curcuminoids percentage, providing verifiable proof of potency on every COA.
04. How do you ensure the product is free from toxic synthetic dyes?
The adulteration of turmeric with Lead Chromate is a known industry risk. We completely mitigate this by sourcing only whole rhizomes directly from verified GAP plantations, bypassing third-party powder brokers. Every batch is rigorously tested via ICP-MS for heavy metals.
05. What is the Minimum Order Quantity (MOQ) and packaging standard?
Our standard MOQ for mass production is 25kg, packed in heavy-duty cardboard drums lined with double sterile, nitrogen-flushed bags to prevent oxidation and moisture ingress. We also supply 1kg foil bags for pilot manufacturing and clinical R&D trials.
