- Product Description
Premium Kaempferol Powder | 98% HPLC Purity | Plant-Derived Bioactive Compound
Are you looking for high-quality kaempferol powder for health supplements or pharmaceuticals? Shaanxi Hongda is a trusted supplier in the health supplement industry. We utilize advanced high-performance liquid chromatography (HPLC) to verify that the purity of our natural kaempferol (derived from Sophora japonica seeds) is at least 98%, meeting the stringent pharmaceutical development standards of the United States Pharmacopeia/European Pharmacopeia (USP/EP). We collaborate with leading pharmaceutical companies in over 30 countries worldwide, and our industry-leading cGMP production facilities strictly adhere to all relevant regulations.
Hongda offers customized micronized kaempferol, controlling the particle size to below 5μm. Micronization increases the dissolution rate of kaempferol in the intestine by approximately 45%, effectively addressing absorption bottlenecks in tablet or capsule development for our clients. Furthermore, Shaanxi Hongda performs batch-to-batch impurity screening to ensure the purity of the kaempferol monomer, free from cross-interference from quercetin or isorhamnetin. Our kaempferol extract has potential benefits in cancer treatment, cardiovascular disease prevention, and anti-inflammatory therapy development.

Research-Backed Health Benefits
1️⃣ Anti-Inflammatory Powerhouse
Kaempferol extract stops important inflammatory indicators including COX-2, TNF-α, and IL-6 from working. This makes it a great tool for researching models of chronic inflammation. Experts looked at studies that showed it alters the NF-κB pathway in a way that relies on how much there is.
2️⃣ Cardiovascular Support
Sophora japonica extract kaempferol decreases oxidative stress and helps endothelial cells work better. In controlled circumstances, it has been proven to inhibit LDL oxidation 68% of the time.
3️⃣ Oncology Applications
Kaempferol Powder kills cancer cells by altering the PI3K/AKT pathways. A new study says that some chemotherapy drugs function better when they are used with additional drugs.

Why Choose Our Kaempferol Powder?
🔬 Pharmaceutical-Grade Quality
Every run goes through at least twelve testing for safety and purity. Heavy metal screening (USP <232>) and residue solvent analysis (ICH Q3C) are two examples. If you store it as advised, stability studies suggest that it will survive for 24 months.

🌱 Customizable Formulations
You may modify the size of the particles (10–200 µm), how well they break, or the combination of excipients to build a tablet or a liposomal delivery system that works for you.

🌍 Reliable Global Supply
Our completely integrated manufacturing makes sure that we always have everything we need, from providing things at the appropriate temperature to acquiring the raw materials in a way that is fair. We take care of immigration papers and support DDP/DAP terms.

Bulk Order Perks
- Flexible MOQs: Start with 1kg for R&D or scale to 20+ MT for commercial projects.
- Cost Efficiency: Volume discounts reduce per-unit costs by up to 40% for ton-scale orders.
- Dedicated Support: Access 24/7 technical consultations and regulatory submission guides.

Comprehensive Quality Control and Certifications
Standards for good research must never alter. Our factories follow rules that are FDA-registered, ISO 9001/13485-certified, and cGMP-compliant. For instance, ICH Q3C standards indicate that you have to check for remaining solvents, USP <232> says you have to check for heavy metals, and USP <61> says you have to check for microbiological populations.
Every product comes with a Certificate of Analysis, a report on a stability assessment, and verification from a third-party lab. This whole collection of papers makes it easier for you to submit your regulatory paperwork and speeds up the approval process for your drug applications.

FAQs
1. What extraction method is used for your Kaempferol ?
We utilize ethanol-water extraction and then column chromatography to make sure the sample is more than 98% pure and still has its biological qualities.
2. Is there data on Kaempferol’s bioavailability?
Yes. Our water-soluble versions are 3.2 times more bioavailable than regular powder when tested on rodents.
3. Do you provide GMP-compliant batches?
Absolutely. We are FDA-registered, and our factory generates clinical-grade batches that can be completely traced and have DMF support.
4. Can Kaempferol interact with CYP450 enzymes?
In vitro studies show mild CYP3A4 inhibition—we recommend dose adjustments when combining with substrates.
5. What’s the NOAEL for your powder?
Rodent studies indicate a NOAEL of 250 mg/kg/day, equivalent to 1.5g/day for a 60kg human.
Conclusion
Kaempferol Powder is a natural vitamin that has a lot of possible health benefits and may be utilized in a lot of different ways. If you want to improve your immune system, lower inflammation, or just feel better in general, kaempferol is an excellent vitamin to add to your health regimen.
