Product Description
Pyrroloquinoline quinone, commonly known as PQQ, is a naturally occurring quinone compound used as a nutritional ingredient in dietary supplements and functional formulations. It is valued by formulators for its bioactive properties, stable crystalline powder form, and compatibility with advanced wellness product development.
PQQ is categorized as a nutritional ingredient rather than a botanical extract. Commercial PQQ is typically supplied as pyrroloquinoline quinone disodium salt powder, which offers improved handling characteristics for supplement manufacturing. Buyers usually evaluate PQQ based on purity, assay method, salt form, and documentation quality.
Pyrroloquinoline quinone (PQQ) is a small quinone molecule originally identified as a bacterial cofactor and later studied as a naturally occurring compound found in various foods and biological systems. The commercially used form is commonly pyrroloquinoline quinone disodium salt, supplied as a fine red-brown crystalline powder.
For supplement manufacturers, PQQ specification control is important because the ingredient is generally used at low dosage levels where accurate assay testing, purity verification, and formulation consistency are essential.

PQQ is commonly used in capsules, tablets, and premium nutritional blends. It is often combined with complementary nutritional ingredients in formulations targeting energy, healthy aging, and overall wellness positioning.
Due to its unique quinone structure and research interest, PQQ is incorporated into specialty nutrition products where innovative bioactive ingredients are required.
PQQ can be integrated into OEM supplement projects including capsules, tablets, powder blends, and customized formulations. Manufacturers typically consider dosage accuracy, ingredient compatibility, and stability during product development.
Unlike many bulk nutritional powders, PQQ is commonly used as a high-value, low-dose active ingredient. The most important procurement factors are purity level, analytical verification, and formulation compatibility rather than simply powder volume.
| Selection Factor | Why It Matters | Buyer Consideration |
|---|---|---|
| Purity / Assay | Determines active ingredient concentration and dosage consistency | High-purity PQQ grades are commonly preferred for premium supplement formulas |
| Salt Form | Affects handling, stability, and manufacturing convenience | PQQ disodium salt is the common commercial supplement form |
| Analytical Documentation | Supports quality verification during raw material approval | COA, HPLC assay data, and safety testing documents are important for procurement review |
PQQ powder is commonly packaged in sealed aluminum foil bags or fiber drums to maintain product stability during storage and transportation. Packaging formats can be customized according to project requirements.
