Bioactive Herbal Powders for Targeted Nutritional Formulations

Q1: How do you verify the botanical identity (ID testing) of your extracts?

A: At Purecium, preventing botanical adulteration is paramount. We utilize advanced macroscopic, microscopic, and chromatographic techniques (such as HPTLC and HPLC) to verify the exact plant species and strictly quantify active marker compounds before any batch is released to our B2B partners.

Q2: Do you provide Certified Organic fruit and vegetable powders?

A: Yes. We offer a comprehensive line of organic superfood powders, including Organic Ashwagandha, Barley Grass, Beet Root, and Blueberry powders. These are specifically processed without synthetic pesticides to support premium clean-label and vegan formulations.

Q3: Are your active marker compounds measured by HPLC or UV?

A: The testing method depends on the specific botanical and global pharmacopoeia standards. For instance, our Berberis Aristata (97%) and Curcumin (95%) are strictly verified via high-performance liquid chromatography (HPLC) for precise quantification, while broader flavonoid profiles may utilize UV spectrophotometry. We clearly state the testing method on every COA.

Q4: How do you control residual solvents in your extraction process?

A: We prioritize green extraction technologies. We primarily use purified water and food-grade anhydrous ethanol. All residual solvents are rigorously tested and tightly controlled well below the 5,000 ppm USP limit, ensuring complete safety for dietary supplements.

Q5: Is your Berberine extracted from endangered plant species?

A: No. To ensure sustainability and supply chain resilience, our premium Berberine HCL and Granular forms are sustainably extracted from Berberis Aristata, serving as an eco-friendly and highly potent alternative to endangered species like Coptis chinensis.

Q6: What forms of Green Tea Extract do you supply?

A: We supply highly customizable Green Tea Extracts tailored for weight management and cognitive formulas. Our portfolio ranges from high-EGCG profiles (EGCG 50% / Catechins 80%) to extracts specifically standardized for natural L-Theanine (20% to 40%).

Q7: Do you supply specific granular forms for direct tableting?

A: Yes, we understand the mechanical needs of contract manufacturers. We offer specific granular options, such as our Berberis Aristata Extract (97% Granular) and Lycopene (10% Granular), which provide superior flowability for high-speed capsule filling and direct compression tableting.

Q8: Are your botanical extracts irradiated?

A: We avoid irradiation whenever possible. We employ advanced sterilization techniques, such as steam sterilization, to control microbial limits while preserving the bioactive integrity of sensitive compounds like Anthocyanins and Polyphenols.

Q9: What is the difference between your Ginkgo Biloba specifications (24/6 vs 24/6/5)?

A: Our standard Ginkgo Biloba Extract (24/6) contains 24% Flavonoids and 6% Lactones. The (24/6/5) specification further guarantees that Ginkgolic acids (a potential allergen) are strictly controlled to less than 5 ppm, fully complying with rigorous USP and European Pharmacopoeia (EP) standards.

Q10: Are your heavy metal limits compliant with European standards?

A: Yes. Across our entire herbal extract portfolio, heavy metals are rigorously controlled to meet both EU and USP benchmarks: Lead < 0.5 ppm, Mercury < 0.1 ppm, Arsenic < 3 ppm, and Cadmium < 1 ppm.

Q11: Do you offer highly concentrated extracts for anti-aging formulations?

A: Absolutely. We supply premium standardized longevity ingredients, including Polygonum cuspidatum extract (up to 98% Resveratrol), Fisetin (98%), Apigenin (98%), and Grape Seed Extract (95% OPC), designed for advanced cellular health brands.

Q12: What is your Minimum Order Quantity (MOQ) for bulk extracts?

A: Our standard commercial packaging is a 25kg net weight drum (Dimensions: 40cm x 40cm x 50cm). The standard MOQ is 25 kg, though we offer flexibility for highly concentrated or specialty active compounds (such as high-purity Huperzine or Lutein).

Q13: Do you provide white-label contract manufacturing for botanical blends?

A: Purecium strictly operates as a B2B raw ingredient supplier. However, we partner with fully certified CDMOs to facilitate end-to-end white-label services, delivering finished tablets, capsules, softgels, and gummies using our premium extracts.

Q14: What quality certifications do your manufacturing facilities hold?

A: Our entire botanical supply chain operates under strict global compliance. Our facilities hold ISO9001, Kosher, Halal, and FSSC22000 certifications, ensuring seamless international customs clearance.

Q15: What is the delivery timeframe for international bulk orders?

A: For procurement teams in the United States, Canada, and Mexico, we offer rapid 2-day pickup from our strategically located US warehouses. Global orders to Europe and other regions are dispatched directly from our China facilities, typically via air freight within one week.
