Quick relief when you need it most!

Take ColdDx ("Cold Dee-Ex") restoratively to get your immune system back on track. ColdDx is formulated with "cold" and bitter herbs that calm overactive immune function to help you feel better fast. ColdDx quickly restores balance to your immune system when it's been knocked out of whack by the stresses of fatigue, over-exposure, seasonal changes or cold weather.*

In a human gene expression study, ColdDx significantly decreased expression of a broad spectrum of genes that control inflammatory cytokine production.*

ColdDx is the solution you need to keep you feeling your best!*

Immediate use: For quick relief, adults take up to 6 servings per day (2 capsules per serving) for up to 2 weeks at a time as needed.

Daily use: Adults take 1-2 capsules per day to curb general inflammation.

"Cold" herbs such as those in ColdDx are often quite bitter and serve to calm and rebalance the body's functions. They close the pores, diminish the activity of the GI tract, and act as powerful anti-inflammatories.*

ColdDx works in part by curbing your body's production of cytokines, which are molecules that cause discomfort when your immune system is working too hard.*

ColdDx also includes herbs such as Andrographis, Belamcanda, and Platycodon that promote respiratory health.

Plantiva vs. Other Brands

  • Created By Experts - Not By AI
    Our products are formulated by healthcare practitioners including herbalists, licensed acupuncturists and medical doctors; and they've been fine-tuned in decades of clinical practice to ensure they really do work for most people. Other companies often don't have a single herbalist on staff and many increasingly rely on AI to throw formulas together with no actual human expertise involved.  We shudder to think of it!
  • Multi-Pronged Formulation Approach
    Our experts have 3 goals for our products: 1) to provide quick relief from immediate discomfort; 2) to address the physiologic imbalances at the root of many health conditions; and 3) to ensure the product is well-tolerated. This goes far beyond the formulation strategies of many other companies, most of which simply combine together a range of herbs believed to have some relevance to a particular health condition with little understanding of how they will interact or how they affect various systems in the body.
  • Quality Controlled from Farm to Bottle
    Most companies delegate their ingredient sourcing to a contract manufacturer. This means their products are made with the cheapest ingredients available, rather than the highest quality available. This is simply unacceptable to Plantiva. We source our botanicals directly from our approved growers, after which they're extracted and bottled at GMP certified facilities according to our stringent requirements. We perform testing at every stage of the process to ensure every batch meets our high standards.
  • Natural Solvents and Minimal Fillers 
    We use only natural solvents such as water and alcohol (ethanol), and we use only small amounts of fillers (less than 10%) in our extracts - the minimum needed to ensure powder flow and consistency. In contrast, some companies use toxic solvents ranging from methanol to hexane to camp-stove fuel, and many companies dilute their extracts with up to 90% filler to save money and minimize the impurities that occur in every natural material.
  • Scientifically Validated
    Our products have been extensively studied as complete formulas, not only in clinical trials but also in mechanism and gene expression studies. In contrast, most other companies rely on studies of individual ingredients and can only hope that their ingredient matches what was in the published study or that their combination of ingredients will produce the desired effect.
