Patents Assigned to Mannatech, Incorporated
  • Antioxidant compositions and methods thereto
    Patent number: 8231914
    Abstract: The present invention provides a performance assay that measures the total antioxidant activity of a composition using oxygen uptake in contrast to prior art methods that measure antioxidant capacity by indirectly measuring degradation of a fluorescent compound by following the disappearance of fluorescence. Using the performance antioxidant assay of the present invention, an antioxidant composition having synergistic activity is provided by the present inventors that includes flavonoids such as the flavonol quercetin, mixed tocopherols or tocotrienols, grape skin extract, green tea extract and bush plum. The antioxidant activity of the present composition exceeds 6,000 micromoles Trolox equivalent units per gram using the present invention.

  • Rapid serum sugar biomarker assay of rheumatoid arthritis
    Patent number: 8173437
    Abstract: The present invention includes compositions, methods, kits and diagnostics for biosugar profiling of biological samples from a patient suspected of having a disease associated with changes in the biosugar profile. The biosugar profile from the patient sample is compared to a healthy biosugar profile from the same type of biological sample to evaluate disease potential and progression.
