Typical NMN Supplement

The Old Way
  • Underdosed

    Many brands dose well below what's used in published research.

  • Proprietary blends

    Exact ingredient amounts are hidden behind a blend label.

  • No third-party testing

    Purity and potency claims often go unverified.

  • Unclear sourcing

    Manufacturing origin and standards aren't disclosed.

  • No real guarantee

    Once it's opened, most brands won't offer a refund.
