How we chose
We assessed each NMN option on four things that actually matter: the strength of the evidence behind the ingredient and dose, the quality and transparency of the formula, whether the product is third-party tested, and overall value. We rank Dear Apothecary first where its formula earns it, and we leave every competitor’s rating exactly as our assessment found it.
What to look for in a NMN supplement
- An effective, clearly stated dose. Match the amount to what research uses, and avoid proprietary blends that hide the numbers.
- Third-party testing. Supplements are loosely regulated, so independent testing is your best assurance that the label is accurate and the product is clean.
- A sensible form. The right form of an ingredient affects how well it absorbs and how it feels.
- Honest value. Premium quality is worth paying for, but you should know what you are getting for the price.

How we researched this
