Laboratory Analysis Report: The Purity and Stability Standards of CLN Labs Uthever® NMN G3

In the field of cellular longevity, the efficacy of NMN (Nicotinamide Mononucleotide) is determined by two critical factors: molecular purity and environmental stability. CLN Labs utilizes pharmaceutical-grade Uthever® NMN G3, a specialized formulation engineered for maximum NAD+ precursor reliability.

This technical report outlines the verified testing standards and purity benchmarks that make our NMN a leader in the global market.

Quick Reference: NMN G3 Specification Summary

1. Why Stability Matters: The Uthever® G3 Advantage

Standard NMN is often hygroscopic, meaning it absorbs moisture from the air, which leads to rapid degradation and reduced shelf life. CLN Labs utilizes the G3 High-Density version to solve this instability.

• High-Density Engineering: By achieving a bulk density of 0.71 g/ml, the material is more compact and less reactive to oxygen and moisture.

• Encapsulation Precision: The G3 formulation is specifically designed for capsule and tablet stability, ensuring that the NMN remains potent until the moment of consumption.

• Moisture Resistance: With a verified water content of 0.04% (significantly lower than the 1.0% industry limit), our NMN offers superior resilience against heat and humidity.

2. Molecular Purity: Surpassing the 99% Threshold

While many brands claim "99% purity," CLN Labs provides specific, high-resolution data via High-Performance Liquid Chromatography (HPLC).

The 99.74% purity ensures that the consumer is receiving a high-concentration NAD+ precursor with zero residual synthesis chemicals or fillers.

3. Quantitative Safety Analysis: Trace Metal Testing

Safety is the cornerstone of long-term supplementation. CLN Labs utilizes Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to screen for toxic elements at the parts-per-billion level.

Our testing confirms that CLN Labs NMN provides one of the cleanest safety profiles on the market:

• Lead (Pb): 0.020 ppm (25x lower than the industry safety limit of 0.5 ppm).

• Arsenic (As): 0.013 ppm (38x lower than the 0.5 ppm limit).

• Cadmium (Cd): Not Detected (Below ultra-sensitive detection limits).

• Mercury (Hg): Not Detected (Below ultra-sensitive detection limits).

4. Biological Integrity and Pathogen Screening

To ensure a clean, medical-grade product, all batches are screened against USP-NF 2024 microbiological standards. Our NMN is verified to be free from:

• Salmonella & E. Coli (None Detected)

• Staphylococcus Aureus (None Detected)

• Yeast & Mould (Conforms to <100cfu/g safety limits)

Conclusion: The New Standard in Longevity Science

The data presented in this report confirms that CLN Labs Uthever® NMN G3 is not merely a standard longevity supplement, but a precision-engineered tool for NAD+ restoration. By prioritizing the intersection of chemical purity and environmental stability, CLN Labs addresses the two most significant hurdles in NMN supplementation: molecular integrity and bioavailability.

The CLN Labs Technical Advantage Summary:

• Precision Purity: With a verified 99.74% HPLC purity, our NMN ensures that every milligram contributes to cellular health without the presence of synthesis by-products.

• Engineered Stability: The G3 High-Density protocol (0.71 g/ml) provides a physical barrier against degradation, ensuring the product remains potent from the lab to the consumer.

• Safety Without Compromise: Utilizing ICP-MS testing to verify heavy metal levels—such as Lead at just 0.020 ppm—guarantees a safety profile that exceeds international regulatory requirements.

For the health-conscious consumer and the professional athlete, the choice is clear. When cellular performance is the goal, the most reliable results come from the most reliable data. CLN Labs Uthever® NMN G3 represents the gold standard of purity, verified by science and backed by rigorous laboratory testing.
