July 2025 Test results Summary

🧪 Third-Party Tested for Purity & Safety

At GroovyNMN, quality is everything. That’s why every batch is rigorously tested by an independent ISO-accredited lab in California, USA.

99.6% Pure NMN
Our latest batch of NMN tested at an exceptional 99.6% purity, using HPLC testing methods that meet internationally recognised standards (USP/NF, EP, JP, AOAC). This ensures you’re getting the highest quality NMN – nothing more, nothing less.

Tested for Heavy Metals
We go beyond basic testing. Our NMN is screened for four heavy metals using advanced ICP-MS technology:

  • Lead: Just 0.015 ppm

  • Arsenic: Only 0.011 ppm

  • Cadmium: 0.002 ppm

  • Mercury: Not detected (below 0.000015 ppm)

These results are well below UK and EU safety limits for food supplements.
