Alpha-Ketoglutarate (AKG) — Premium Krebs Cycle Intermediate for Longevity & Sports Nutrition Formulations

Frequently Asked Questions for QA & Procurement

Q1: Is Purecium's Alpha-Ketoglutarate (AKG) considered a natural or synthetic product?

A: Our AKG is a 100% natural product. It is produced exclusively through microbial fermentation using Non-GMO corn as the starting material, rather than through chemical synthesis. This ensures a clean, bio-identical compound ideal for premium dietary supplements.

Q2: What are the specific heavy metal limits for your AKG products?

A: Our AKG strictly complies with both EU and USP standards for heavy metals. The limits are rigorously controlled as follows: Lead (Pb) < 0.5 ppm; Arsenic (As) < 3 ppm; Cadmium (Cd) < 1 ppm; Mercury (Hg) < 0.1 ppm.

Q3: Are there any solvent residues in your AKG, and what is the mesh size?

A: We use food-grade anhydrous ethanol during the production process. The residual ethanol level is strictly controlled to be under 5,000 ppm, fully complying with USP standards. The finished product is processed into a highly soluble 80-mesh fine white powder.

Q4: Does Purecium supply finished retail AKG products or offer OEM services?

A: Purecium operates strictly as a B2B supplier of raw nutritional ingredients to distributors, contract manufacturers, and terminal brands. While we do not sell retail products, we partner with premier contract manufacturers to provide end-to-end white-label OEM services for AKG tablets, hard capsules, softgels, and energy gummies.

Q5: What is the Minimum Order Quantity (MOQ) and packaging standard?

A: Our standard MOQ is 25 kg. The AKG powder is securely packed in 25kg drums (Dimensions: 40cm x 40cm x 50cm; Gross weight: 28 kg) with protective inner liners to maintain absolute purity during global transit.

Q6: What are the shipping terms and estimated delivery times?

A: All bulk orders are shipped directly from our manufacturing facilities in China. For global B2B clients, dispatch and delivery are typically arranged and completed within one week of the order confirmation.

Q7: Can Purecium guarantee a stable, long-term supply of AKG?

A: Yes. By utilizing scalable microbial fermentation technology and renewable raw materials (corn), Purecium maintains robust production capabilities, guaranteeing a consistent and long-term supply for large-scale contract manufacturers without price volatility.

Q8: What quality certifications does Purecium hold for AKG production?

A: Our manufacturing facilities are highly regulated and certified. We provide full documentation including ISO9001, Kosher, Halal, and FSSC22000 certifications for our Alpha-Ketoglutarate raw materials.

Q9: Do you provide COAs and stability reports for formulation validation?

A: Absolutely. We provide batch-specific Certificates of Analysis (COA) along with comprehensive data from both accelerated and long-term stability tests. Formulators and QA teams can request these reports directly by contacting [email protected].

Q10: What are the optimal storage conditions and shelf life for bulk AKG?

A: To maintain product integrity, AKG powder must be stored in a tightly sealed container in a cool, dry place, strictly away from direct light. Under these optimal conditions, the product has a guaranteed shelf life of 24 months.
