Ingredients, Sourcing, and Process

Dr. Allan Miller, ND Dr. Allan Miller, ND
It's almost impossible to find a supplement brand genuinely transparent about where they source their ingredients. However, we believe that if you'll  be trusting us with your health, the least we can do is inform you of even the most minor details of our production process.

By doing so, we can truly say that our solutions are safe, high-quality, nutritious, and effective.

Read on to learn about our sourcing process and how we deliver the most absorbable liposomal supplements on the market.

Where Our Ingredients Come From

Each ingredient we use has specific roots in different parts of the world — and to ensure we get the best quality product, we go directly to the source - no matter what it takes. 

For example, our gum stabilizer - a natural thickening agent - comes directly from Austria and regions of Chad and Nigeria, the locations with the highest grade available. The same vetting process is done for every single ingredient we use.

Sustainable Practices

Sustainability and corporate responsibility are two key pillars on which we built our company. 

Hence, when sourcing our ingredients, we do so in the most sustainable way possible. 

For example, no 2x4® ingredient comes from areas in South America simply because of their practices around deforestation in the Amazon Rainforest. The resulting damage to the ecosystem goes against everything our organization stands for. 

So, in summary, when looking for new farmers and suppliers, we look at not only the purity of ingredients but also the impact they have on the environment.

Ensuring Our Ingredients Are Safe

Each time a batch of ingredients arrives at our facility, they're put through what we like to call a "quarantine phase." This means we isolate every batch in a secure area free from contamination, after which each batch is tested to ensure it meets safety standards. 

We also check to ensure the absence of contaminants like heavy metals, pesticides, solvents, or harmful pathogens and microbes. 

We have a zero-tolerance policy for harmful impurities in our products. If any of these tests do not pass our quarantine phase, the batch is disposed of, and we discontinue use from the source immediately.

Manufacturing Our Solutions

Once a batch of ingredients has passed all our testing procedures and our team has verified its purity and quality, we move to formulate and manufacture your favorite 2x4 solutions. 

Our solutions are formulated using our patented 2-step Nutristack® Technology, protecting the nutrients in tiny microscopic bubbles. 

If you ever find yourself in a lab, try looking through a drop of any of our solutions under a microscope. 

Spoiler alert: You'll find thousands of tiny little bubbles. 

What this does is allow our solutions to be absorbed by your body, as well as target the areas in which the nutrient is needed.

In addition to all the testing we put our suppliers and ingredients through, we also ensure our manufacturing facility is operated at the highest standard possible. Our Colorado manufacturing facility is FDA tested, ISO certified, and cGMP certified.

Final Product Testing 

Once our solutions come off the production line, we put them through the same battery of tests that we put all our ingredients through at the beginning of the process. 

This ensures that your 2x4® solutions haven't picked up any harmful pathogens or contaminants before shipment. 

So you can rest assured that all the ingredients in your 2x4® solutions are safe, effective, and targeted, giving you and your family the best supplement solutions available on the market today. 

When you purchase a 2x4® solution, you're buying something that has been tested for efficacy and quality. We believe you and your family deserve only our very best.
