Advanced Mineral Chelates & Salts for Maximum Bioavailability

Q1: How do you ensure your Magnesium Bisglycinate and Zinc Glycinate are fully reacted chelates?

A: At Purecium, we utilize advanced Fourier-transform infrared spectroscopy (FT-IR) to verify the molecular structure of our amino acid chelates. This ensures our Magnesium and Zinc Glycinates are fully reacted, unadulterated chelates, rather than simple dry blends of oxides and amino acids, guaranteeing maximum bioavailability for terminal brands.

Q2: What is the difference in elemental yield between Calcium Carbonate and Calcium Citrate?

A: Calcium Carbonate provides the highest elemental calcium yield (approximately 40%), making it cost-effective for dense solid dosages. Calcium Citrate provides a lower elemental yield (around 21%) but offers vastly superior solubility and is absorbed independently of stomach acid, making it ideal for premium and geriatric formulations.

Q3: Are your mineral powders suitable for direct compression tableting?

A: Yes. We engineer our mineral powders (such as Calcium Carbonate and Magnesium Oxide) with optimized bulk density and customized mesh sizes to ensure excellent flowability and compressibility for high-speed direct compression tableting by contract manufacturers.

Q4: How do you control heavy metal limits in your bulk minerals?

A: Heavy metal contamination is a critical concern for mineral sourcing. Purecium strictly enforces both EU and USP limits (Lead < 0.5 ppm, Arsenic < 3 ppm, Cadmium < 1 ppm). Every batch undergoes rigorous ICP-MS testing to ensure compliance with stringent global regulations, including California Proposition 65.

Q5: What is the difference between Chromium Picolinate and Chromium Trichloride?

A: Chromium Picolinate is a highly bioavailable chelated form extensively used in premium blood sugar and metabolic management supplements. Chromium Trichloride is an inorganic salt form, offering a highly cost-effective solution for standard multivitamin and mineral premixes.

Q6: Which form of Magnesium is best suited for liquid formulations and RTD beverages?

A: For aqueous applications, Magnesium Citrate Powder and Magnesium Gluconate Powder are the preferred choices. They offer exceptionally high water solubility and a neutral taste profile compared to insoluble forms like Magnesium Oxide.

Q7: Do you provide Ready-to-Use (RTU) bulk packaging for contract manufacturers?

A: Yes. Our bulk mineral raw materials are supplied in highly protective, moisture-barrier Ready-to-Use (RTU) 25kg drums, designed to drop seamlessly into the production lines of CDMOs and terminal brands.

Q8: What is Calcium Citrate Malate (CCM) and why is it used?

A: Calcium Citrate Malate (CCM) is a highly specialized matrix of calcium, citric acid, and malic acid. It is globally recognized for having one of the highest absorption rates among calcium salts and is exceptionally effective for fortifying juices and functional beverages without settling.

Q9: How stable are your Ferrous (Iron) salts like Ferrous Fumarate and Ferrous Lactate?

A: Both Ferrous Fumarate and Ferrous Lactate exhibit excellent physical stability. Ferrous Fumarate offers a very high elemental iron content (approx. 33%) and is highly stable against oxidation, making it a staple in solid-dose hematology and prenatal supplements.

Q10: What is the elemental concentration of your Zinc ingredients?

A: Our portfolio covers various formulations: Zinc Oxide provides the highest elemental zinc (approx. 80%) for topical and dense solid applications, while Zinc Citrate (approx. 31%) and Zinc Gluconate (approx. 14%) are preferred for their superior absorption and gastric tolerability in oral supplements.

Q11: Are your mineral raw materials vegan and clean-label compliant?

A: Yes. Our entire mineral portfolio, including our organic acid salts (Citrates, Malates, Lactates) and amino acid chelates, is synthesized without animal-derived inputs, making them 100% vegan, non-GMO, and clean-label compliant.

Q12: What quality certifications do your manufacturing facilities hold?

A: Purecium operates under strict global compliance. Our manufacturing facilities are fully audited and hold ISO9001, Kosher, Halal, and FSSC22000 certifications, ensuring seamless international customs clearance.

Q13: Do you sell finished mineral supplements to individual consumers?

A: No, Purecium exclusively operates as a B2B raw ingredient supplier. We partner strictly with global purchasing specialists, distributors, and contract manufacturing organizations (CDMOs).

Q14: Can you provide comprehensive Certificates of Analysis (COAs) with each batch?

A: Absolutely. Every shipment is accompanied by a detailed COA verifying elemental assay, heavy metal limits, microbial safety, and physical properties (mesh size, bulk density), verified by advanced analytical testing.

Q15: What are the shipping lead times for bulk international 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 are dispatched from our FSSC22000-certified facilities in China, typically within one week via air or sea freight.
