Product Overview & Core Functions

Curcumin is the main active polyphenolic ingredient extracted and purified from turmeric (Curcuma longa L.) rhizome. It is widely recognized as a classic natural antioxidant and anti-inflammatory raw material in global nutraceutical, cosmetic, and functional food industries. Adopting low-temperature solvent extraction and recrystallization technology, we fully retain the natural curcumin active structure while eliminating common drawbacks like low active content and poor solubility.

  • Powerful Natural Antioxidant: Efficiently scavenges free radicals, reduces cellular oxidative damage, and delays aging.

  • Anti-Inflammatory Activity: Modulates inflammatory factor expression to relieve chronic mild inflammation and body inflammatory sub-health status.

  • Support Joint Health: Maintains joint cartilage vitality and eases joint stiffness and soreness, widely used in joint care nutritional supplements.

  • Skin Antioxidation: Inhibits inflammatory pigmentation and resists external oxidative damage in high-end cosmetic raw material systems.

🧪 Dual Specification Advantages

We offer precision purification technology ensuring stable curcumin content. The 98% grade meets high-end formulation requirements with secondary recrystallization, while the 95% version offers a cost-effective choice for mass production.

  • Non-GMO, low solvent residue, compliant with clean label trends.

  • Uniform orange-yellow powder, stable color under proper storage.

  • Heavy Metal (Pb) ≤10ppm, Arsenic (As) ≤2ppm.

Formulator & Buyer FAQ

Q1: What is the difference between 95% curcumin and 98% curcumin?
98% curcumin adopts secondary recrystallization purification, resulting in lower impurity content and higher purity, suitable for high-end nutraceutical and cosmetic formulations. 95% curcumin is highly cost-effective and widely used in conventional joint care and antioxidant health products. Both are tested by HPLC and meet international raw material standards.
Q2: Curcumin is insoluble in water, how to improve its absorption?
Curcumin is lipophilic and poorly soluble in water. It can be compounded with piperine (black pepper extract) to inhibit metabolic decomposition and significantly improve bioavailability. It can also be prepared into microcapsules, nano-emulsion, and oil-soluble formulations to enhance the absorption effect.
Q3: What are the main application fields of curcumin?
Curcumin is widely used in joint health supplements, antioxidant and anti-inflammatory functional foods, gastrointestinal conditioning products, and antioxidant skincare raw materials. It can be used alone or compounded with other plant extracts, meeting broad market demand.
Q4: What is your after-sales guarantee policy?
We provide long-term professional after-sales technical support and strict quality assurance. For any confirmed product quality problems, we support free product replacement and full refund to fully protect the legitimate interests of all cooperative customers.
