At Nature’s Evolution Peptides, we prioritize transparency and providing reliable research materials. Many researchers ask whether NAD⁺ remains stable during shipment and short-term storage, given its sensitivity to heat and light.

To provide clear, data-backed answers, we partnered with Vanguard Laboratory, an independent analytical testing facility, to conduct a dedicated stability analysis on our NAD⁺ solution.

Why This Study Was Conducted

NAD⁺ (Nicotinamide Adenine Dinucleotide) plays a critical role in cellular metabolism and redox reactions. Researchers often wonder:

• Does shipping affect NAD⁺ quality?
• Does heat exposure cause degradation?
• Does short-term storage impact purity or concentration?

This controlled study provides real-world evidence addressing these questions.

Overview of the Stability Test

Three vials of Nature’s Evolution Peptides NAD⁺ solution (200 mg/mL nominal concentration) were evaluated under realistic shipping and storage conditions:

Shipping Conditions Tested:

• Fast transit (12–15 hours, Next Day Air)
• Extended transit (~3 days, Standard USPS)

Storage Conditions After Arrival:

• One vial refrigerated (2–8 °C)
• One vial stored at room temperature (20–25 °C)
• One vial tested immediately

Testing Method: HPLC-UV/Vis, a gold-standard method for assessing purity and degradation compounds.

Key Findings

• Fast Transit (12–15 hours): No meaningful degradation; purity 99.6%
• Extended Transit (~3 days): Minimal degradation (~2.22%); purity 99.56%
• Refrigerated Storage (7 days): No change in purity or concentration
• Room Temperature Storage (7 days): Minor degradation (~2.67%), consistent with mild hydrolysis

Projected Long-Term Stability:

• ~11.4% loss after 30 days at room temperature
• ~22.8% loss after 60 days at room temperature
• Refrigeration (≤5°C) preserves NAD⁺ for months, supporting published research on NAD⁺ storage behavior.

What Researchers Should Know

• Shipping Does Not Compromise Quality: NAD⁺ withstands normal shipping conditions with negligible degradation.
• Refrigeration Maximizes Stability: Store NAD⁺ in the refrigerator after arrival for optimal preservation.
• Laboratory-Verified Consistency: Independent testing confirms high purity and concentration from shipment to storage.

Final Thoughts

This independent analysis by Vanguard Laboratory demonstrates that Nature’s Evolution Peptides NAD⁺ remains stable during typical shipping and short-term storage. Minor degradation may occur at room temperature over time, but refrigerated storage maintains near-perfect purity and concentration.
