Our success in the health care industry has taught us that quality, safety, and efficacy are intertwined. We’ve carried over the same dedication to uncompromising quality that we use in our pharmaceutical products to REX Genetics nutritional supplements.




We understand that to produce a superior product there is simply no room for subpar ingredients, manufacturing shortcuts, or other deceptive practices that sacrifice quality in favor of marketing “tricks-of-the-trade”. Rather, our products speak for themselves through transparent labelling, manufacturing, and quality assurance procedures which let the quality shine through at all levels.

We maintain strict adherence to the best processing and manufacturing procedures in the industry. This assures that our supplements retain the inherent purity and potency of the organic, non-GMO ingredients that go into them.

Our quality assurance procedures include independent third-party testing and certification. These steps monitor every facet of the production process. And while they may slow the production process they ensure that the resulting product is the best it can be.
