How Duo supplements work

Our mouths absorb nutrients directly into the bloodstream. That’s the key to the efficient bio-availability of the vitamins and supplements in Duo, added for convenience and health.

  • absorbs while you brush
  • gentle, efficient digestion
  • rapid uptake
Standard Supplement Pills
  • uncomfortable to swallow
  • difficult gastrointestinal digestion
  • delayed delivery





Dentist Created







“What you brush 
with matters.”

Tooth enamel cannot repair itself from within, which means your toothpaste has an important job to do. We packed Duo with proven ingredients like nHa to remineralize teeth and promote vibrant oral health. Developed by dentists, better for everyone.
