Guaranteed ORAC Values

While ORAC value is only one piece of the antioxidant puzzle, we test each batch for ORAC value as a quality control measure—to assure that our client-partners are getting the absolute best quality that nature can provide.


Standardized Marker Compounds

OxyPhyte® Antioxidants are standardized and guaranteed for quality, allowing you to make active compound claims:

    • Polyphenols
    • Catechins
    • Resveratrol
    • Anthocyanins

Dependable Claims Substantiation

We guarantee the quality of OxyPhyte® ingredients and have the data to prove it! All of our antioxidant-capacity claims are backed-up by ORAC values and marker content on each COA.



Our OxyPhyte® Ultra Blend has confirmed bioavailability with human volunteers.

In this preliminary study:

  • The baseline ORAC level of blood serum was measured in subjects prior to ingesting 400 mg of OxyPhyte® Ultra (approximately 3600 ORAC units).
  • After consumption, blood serum ORAC was measured after 30 minutes, then again after one hour.
  • Peak blood ORAC levels compared to baseline Increased up to 32% (average was 12%), providing evidence that OxyPhyte® is absorbed into the blood and supports the antioxidant capacity of blood plasma.

Cellular Uptake & Activity

The Cell-based Antioxidant protection in Erythrocytes (CAP-e) is an ex-vivo assay that confirms the cellular uptake potential of an antioxidant, which provides a piece of the antioxidant puzzle not predicted by ORAC.

CAP-e results for OxyPhyte® Antioxidants show that each ingredient has cellar bioavailability and supports healthy redox reactions within cells.
