Original Formula

Established in 1989, in the heart of the Evergreen state in Kent, Washington, our mission remains the same: Delivering the finest specialty products with the highest quality ingredients.


Due to the misrepresentations of the InterPlexus brand and to protect our valued partners, our management has intervened by directly listing InterPlexus products on Amazon.

Currently InterPlexus is a speciality supplement wholesale distributor.
Our products can be purchased in the retail market through many health care practitioners,
pharmacies and health food retailers online and across the US.


InterPlexus, Inc. is a premier purveyor of high quality vitamins, minerals, enzymes, and herbal supplements.


We are committed to using the highest quality ingredients in our product line.
We are equally committed to applying the latest research to our formulations.
