In the global dietary supplement and functional nutrition market, Pyrroloquinoline Quinone (PQQ) and Coenzyme Q10 (CoQ10) have become increasingly relevant—not just as consumer-facing ingredients, but as strategic raw materials for manufacturers focused on cellular energy, mitochondrial support, and healthy aging formulations.
This article is designed for professional buyers, formulators, and brand owners, offering a non-promotional, evidence-based overview of PQQ and CoQ10 from a raw material, application, and sourcing perspective.
Rather than repeating product specifications, we focus on how these ingredients are evaluated, applied, and sourced responsibly in today’s compliant B2B environment.
1. Understanding PQQ and CoQ10 at the Ingredient Level
What Is PQQ (Pyrroloquinoline Quinone)?
PQQ is a redox-active compound naturally found in trace amounts in foods such as fermented soybeans and green peppers. In nutrition science, it is primarily studied for its role in mitochondrial signaling and cellular oxidative balance.
From a raw material perspective, commercial PQQ is typically produced via microbial fermentation, followed by purification to achieve standardized purity levels suitable for dietary supplement applications.
What Is CoQ10?
CoQ10 is a fat-soluble, vitamin-like compound present in human cells, especially within mitochondria. It exists in two main commercial forms:
- Ubiquinone (oxidized form)
- Ubiquinol (reduced form)
Most bulk raw materials used in supplements are fermentation-derived or yeast-based, offering consistent quality and scalability for manufacturers.
2. Why PQQ and CoQ10 Are Often Considered Together
From a formulation standpoint, PQQ and CoQ10 are frequently discussed together due to their complementary roles in cellular energy metabolism:
- PQQ is studied for its involvement in mitochondrial biogenesis signaling
- CoQ10 plays a role in electron transport within mitochondria
Importantly, this synergy is conceptual and biochemical, not a medical claim. For manufacturers, the combination allows for clear positioning in energy, vitality, and healthy aging categories without crossing regulatory boundaries.
3. Scientific Literature Overview (Non-Therapeutic)
To support E-E-A-T, professional buyers often expect transparency regarding the scientific context of an ingredient.
Selected Research Areas
- Cellular redox activity (PQQ)
- Mitochondrial electron transport (CoQ10)
- Age-related nutrient depletion trends
- Bioavailability differences between CoQ10 forms

4. Application Scenarios for Manufacturers
PQQ + CoQ10 raw materials are commonly evaluated for use in:
- Energy & vitality supplements
- Healthy aging formulations
- Cognitive and performance-oriented blends
- Premium daily nutrition products
Dosage & Formulation Considerations
Manufacturers must consider:
- Regulatory-accepted dosage ranges (region-specific)
- Stability in capsules, tablets, or softgels
- Fat-soluble delivery systems for CoQ10
- Compatibility with excipients and other actives
These decisions are formulation-specific and should be validated internally or with regulatory consultants.
5. Quality Standards That Matter in B2B Procurement
Professional buyers rarely focus only on price. Instead, evaluation typically includes:
Key Quality Indicators
- Verified purity (HPLC or equivalent methods)
- Heavy metals and microbial limits
- Batch-level traceability
- Stability data
Documentation Expectations
- Certificate of Analysis (COA)
- Specification sheets
- Allergen statements
- Compliance declarations (FDA / EFSA where applicable)
Reliable suppliers should support audit readiness and transparent documentation.
6. Regulatory & Compliance Landscape
PQQ and CoQ10 are regulated differently across markets:
- United States: Dietary Supplement Health and Education Act (DSHEA)
- European Union: Novel Food status (PQQ), food supplement directives
- Asia-Pacific: Country-specific positive lists
Authoritative references:
- FDA Dietary Supplement Guidance

Manufacturers should ensure labeling and claims remain compliant in each target market.
7. How Professional Buyers Evaluate a PQQ + CoQ10 Supplier
Beyond the ingredient itself, buyers increasingly assess:
- GMP manufacturing capability
- OEM/ODM experience
- Supply chain stability
- Technical communication quality
- Post-sale documentation support
This is where factory transparency and technical expertise become decisive factors.
8. From Education to Action: Next Steps for Buyers
Once formulation feasibility and regulatory alignment are confirmed, professional buyers typically proceed to:
- Review ingredient specifications
- Request COA and compliance documents
- Evaluate MOQ and lead time
- Confirm OEM / private label capabilities
- Submit an inquiry, not a retail order
👉 This structured flow reduces risk and improves long-term sourcing reliability.
FAQ: PQQ + CoQ10 Raw Materials
Is PQQ considered a drug?
No. PQQ is regulated as a dietary ingredient in specific jurisdictions when compliant with local regulations.
What is the difference between ubiquinone and ubiquinol?
They are different redox forms of CoQ10 with distinct stability and formulation considerations.
Can PQQ and CoQ10 be used together in one formula?
Yes, many manufacturers evaluate them together for positioning purposes, subject to regulatory compliance.
What documents should a supplier provide?
COA, specification sheet, safety data, and regulatory compliance statements are standard.
Is clinical data required for marketing?
Claims must align with regional regulations; scientific literature supports ingredient understanding, not disease claims.
