2x4 Cold Reducer™ is a hyper-absorbent solution that may be able to help defend your body from colds and the flu, while also shortening the duration of your cold symptoms. 

The key ingredient in 2x4 Cold Reducer™ is Zinc, an essential nutrient that helps your body fight viruses in order to keep you from getting sick. It is essential for cell growth and division, proper immune function, enzyme reactions, DNA synthesis, and protein production. It not only keeps your immune system strong, but can also support the healing process and help manage symptoms. Zinc may also be able to significantly reduce your risk of age-related diseases, such as pneumonia, infection and age-related macular degeneration. 

Our 2x4 Cold Reducer™ solution is formulated  to deliver zinc directly to your respiratory tract. By doing so, it can help your immune cells fight off cold & flu viruses and bacteria, and may be able to support recovery from colds through rapid absorption 

2x4 Cold Reducer™ may be able to help your body manage and fight off viruses and bacteria, strengthening your immune response, and also accelerating your healing and recovery process. 

Yes! Studies suggest that both topical and oral zinc treatments can effectively treat acne by helping reduce inflammation, inhibiting the growth of P. acnes bacteria, and suppressing oily gland activity.

Though we cannot for sure say that Zinc treats low testosterone levels, research has found that Zinc can increase testosterone production in a male's body.  One study by the ASEP researched the effects of a magnesium and zinc supplements, and found that men who received 30 milligrams of zinc per day showed increased levels of free testosterone in their bodies.

Most colds are caused by a type of virus called rhinovirus, which thrives and multiplies in the nasal passages and throat (or your upper respiratory system). Zinc reduces the symptoms of colds because it prevents the rhinovirus from multiplying. It may also stop the rhinovirus from lodging in the mucous membranes of the throat and nose.

2x4 Cold Reducer™ supports the healing process and may actually be able to help your body fight off the common cold before you get sick. This is because it delivers Zinc directly into your throat, targeting pesky viruses head on.  

Zinc is essential for normal development of the central nervous system and is required for the formation and function of a variety of proteins, enzymes, hormones, and growth factors that direct stem cell proliferation and differentiation during neurodevelopment.

We recommend taking 2x4 Cold Reducer™ (our liposomal zinc solution) with 2x4 Immune Strength™ (a vitamin D3 solution) and/or 2x4 Resilient-C™ (a liposomal Vitamin C solution) in order to potentially maximize your natural immune response. By doing so, you can provide your body with comprehensive immunity support, as well as optimize your respiratory and cardiovascular health, and support your body's natural anti-inflammatory response.

Nutristack Liposomal technology is our patented 2-step delivery process that allows your body to absorb 95% of the nutrients found in your 2x4® solutions. First, our Nutristack technology wraps the nutrients inside tiny, microscopic bubbles that mimic your body's cell membranes. This bubbles are known as Liposomes. Then, the Nutristack delivers those nutrients directly into your bloodstream and through your cell membranes without losing any of the nutrients inside. This increases the bioavailability of our vitamins by over 15x, making them the most absorbing and effective supplement available.

Our Nutristack Liposomal Technology is fast acting, highly absorbable, and effective.

Liposomal supplements are better than your average gummy and pill because they have high absorbability. Simply put, it's a delivery mechanism that ensures your body reaps the full benefits of the vitamins you take, without losing anything along the way.

Liposomal supplements work faster, and have longer lasting effects than traditional supplements and gummies.

Have you ever heard the term "No Pain, No Gain"? That applies to our liposomal solutions. Our vitamin solutions don't taste like candy, but that's because they actually work. Vitamins and nutrients aren't meant to taste good, and if they do, it means the nutrient composition is actually fairly low or non existent. So if you care more about taking vitamins that actually work, then a little bit of pain goes a long way ;) However, you can easily mix all of our vitamins with your favorite juice, smoothie, or breakfast. This should hide the taste completely! 

Absolutely! Our solutions are meant to be stacked, and can be mixed together without upsetting your stomach. We recommend mixing your solutions together with a glass of water, your morning smoothie, or favorite juice for optimal taste
