A label can tell you whether a “NAD+ precursor” product is verifiable or vague. Use this checklist before you buy.
What to confirm on the label:
- Supplement Facts (or equivalent panel): It should list each active ingredient separately.
- Exact ingredient form: Look for NR, NMN, nicotinamide (NAM), or niacin named explicitly. “Vitamin B3” alone is not specific enough.
- Amount per serving: The label should state a numeric amount for each active (not just a blend total).
- Serving instructions: Clear directions and a realistic serving size for your dog’s size.
- Excipients and allergens: Identify flavors, sweeteners, gums, or sugar alcohols that may affect tolerance.
Testing and documentation expectations:
- Third-party testing: Prefer products that provide a recent Certificate of Analysis (COA) showing identity and purity, plus contaminant screening (e.g., heavy metals, microbes).
- Lot/batch traceability: A lot number and manufacturer contact info should be easy to find.
Red flags:
- “Proprietary blend” for actives, missing amounts, no COA availability, or claims that imply disease treatment or guaranteed outcomes.
