Pyridoxal-5-Phosphate Powder (P5P)
Pyridoxal-5-phosphate (P5P) powder for vitamin B6 supplement formulations, including standalone B6, B-complex and multivitamin products. Gensei supplies the ingredient with batch-specific quality documentation for procurement review.
P5P: Pyridoxal-5-Phosphate as a Vitamin B6 Ingredient
Pyridoxal-5-phosphate, commonly abbreviated as P5P, is a coenzyme form of vitamin B6 used in nutritional supplement formulations. The supplied material is a slightly yellow to off-white powder.
For formulation work, its physical properties matter as much as its identity. The specification describes P5P as very slightly soluble in water and includes particle-size, pH, water and density data that can be reviewed against the intended manufacturing process.

Working with P5P Powder in Supplement Formulas
P5P is selected for vitamin B6 formulations where the pyridoxal-5-phosphate form is specifically required. Dosage form, blending behavior and finished-product requirements should be considered during development.
Standalone P5P Supplements
For products that specify P5P as the vitamin B6 source, formulation teams should confirm the intended serving level, label declaration and finished-product requirements before scale-up.
B-Complex Formulas
When P5P is combined with other B vitamins, review the ingredient ratios and blending sequence within the complete formula, then verify blend uniformity using the chosen manufacturing process.
Multivitamin Formulas
In broader multi-nutrient systems, assess P5P alongside the other active ingredients and excipients. Confirm the finished blend and product performance under the intended processing conditions.
Dosage-Form Considerations
For capsules, tablets and powder blends, consider how particle size and density relate to the wider blend. Flow, filling, compression and blend uniformity should be verified in the actual formulation rather than assumed from individual ingredient data.
From Specification Review to Raw-Material Approval
Use the product specification and batch documentation as part of your normal supplier qualification process, alongside your internal standards and finished-product requirements.
Documentation for Review
The representative COA shows the types of information recorded for a P5P batch. Before placing or releasing an order, request the current documentation and confirm that the supplied material meets your approved raw-material specification.
Any additional documents should be discussed according to your quality system, product category and destination-market requirements.
P5P Supply for Supplement Manufacturing
Discuss the order and documentation requirements with Gensei before confirming a supply plan for your production schedule.
패키징
Standard packing is 25 kg per drum. Confirm the required order quantity and any shipment-specific handling needs when requesting a quotation.
