Not all NMN powders are created equal. Key factors to ensure purity, potency, and safety include:
· Purity & Third-Party Testing: Seek powders with ≥99% purity, verified via NMR (Nuclear Magnetic Resonance) or HPLC testing. Hygieia NMN undergoes independent U.S. lab testing for identity and contaminants like heavy metals 110. Avoid products without verifiable Certificates of Analysis (CoAs).
· Production Methods:
· Enzymatic Synthesis: The gold standard, yielding high-purity NMN without toxic solvents
· Fermentation: Eco-friendly but may yield lower purity.
· Chemical Synthesis: Cost-effective but risks solvent residues 9.
· Stability & Form: Powder (over capsules) ensures sublingual absorption. NMN must be protected from light, heat, and moisture to prevent degradation. Some brands use micro-encapsulation for stability 6.
· Additives: Opt for products free from fillers, allergens (e.g., gluten, soy), and artificial additives 1.
