ColdDx™ ("Cold Dee-Ex") is formulated with "cold" herbs, ingredients known to calm and soothe physiologic processes. ColdDx works fast to restore balance to your immune system when it's succumbed to the stresses of fatigue, over-exposure, seasonal changes or cold weather.* 

In a human gene expression study, ColdDx significantly decreased the production of a broad spectrum of inflammation-related cytokines, showing that ColdDx helps maintain inflammatory immune health.*

  • Restores immune balance*
    • Alleviates the discomfort of an overworked immune system*
    • Calms cytokines which cause discomfort*
      • Non-drowsy and stimulant free*
      • Quality controlled from farm to finished product
      • Natural plant-based herbal supplement
      • Vegan

        Suggested use: Immediate use: Adults take up to 6 servings per day (2 capsules per serving) for up to 2 weeks at a time as needed.
        Maintenance use: Adults take 1-2 capsules per day.


        ColdDx has been evaluated in a human gene expression study to examine its effect on the immune system. Human blood samples treated with ColdDx in the presence and absence of an immune aggravator were assessed for the expression of 24 genes involved in inflammatory immune response.

        These genes control cytokine production. Overproduction of cytokines can cause significant discomfort, so proper modulation of cytokine production is essential to feeling your best.

        ColdDx significantly decreased the effects of the immune aggravation, indicating that ColdDx modulates the inflammatory immune response to reduce immune over-reactions.*
