Why Nutritionists Love Real Defense™
resilient
"2x4 Real Defense™ is a major antioxidant throughout the body, meaning it targets and neutralizes free radicals, aka harmful molecules that are normal byproducts of cellular activities and metabolism, or through exposure to sources like pro-inflammatory diets, UV radiation (photoaging), air pollution, cigarette smoking, and pesticides. Pretty cool, right?"

Experts Speak About Real Defense™

2x4 Real Defense™ is an immunity solution created with our health expert and partner Courtney Swan from Realfoodology. This immunity solution is packed with immune-boosting nutrients including Zinc, Vitamin D3, Elderberry, and Quercetin.

2x4 Real Defense™ was created with a proprietary Nutristack® Liposomal Technology that increases nutrient absorption by 15x, making 2x4 Real Defense™ a more effective and fast-acting immunity solution.

Zinc is an essential vitamin that plays a role in immune function and supports the body's natural immune response against bacteria and viruses.

Vitamin D3 helps soothe inflammation and plays a supporting role in immune function. It is also good for bone health and for those who suffer from cramps or muscle spasms.  

Some studies show that Elderberry may help support recovery from flu and cold, reducing duration and severity of respiratory symptoms. 

Quercetin is a flavanol found in plants. It has anti-inflammatory and immunomodulating properties that can help soothe inflammation and aid in fighting infections and diseases.  

Yes! 2x4 Real Defense™ is 100% natural with no artificial flavoring. It's also non-GMO, sugar-free, gluten-free, and vegetarian-friendly.

The reason I chose 2x4 Nutrition to help me with my immunity solution is because they hold a revolutionary technology not available or found in ANY other vitamin or supplement. This technology, known as Nutristack® Liposomal Technology, is a unique delivery system that envelopes nutrients into tiny microscopic bubbles that protect them from deteriorating in the body. Then, this technology delivers the nutrients quickly and directly into the bloodstream, and then immediately into your cells where they’re needed most. This allows your body to absorb 95% of the nutrients, rather than 5-10% as you would with average supplements.

2x4 Real Defense™ has an herbal taste that lies more on the sweeter side. We recommend mixing your solution with a glass of water, or adding it to your morning coffee, oatmeal, or smoothie for optimal taste.

I prefer taking 2x4 Real Defense™ with a green smoothie first thing in the morning.

One bottle, if consumed as instructed daily, should last you 30 days. 

We recommend taking Courtney Swan's 2x4 Real Defense™ with 2x4's Resilient-C™ in order to boost your immunity while also supporting recovery from illness or exercise, soothing inflammation, and for additional antioxidant support. 2x4 Resilient-C™ also promotes collagen production, which helps nurture your skin from the inside. 

Each ingredient has roots in different parts of the world. Thus, we source our ingredients globally, targeting the best source for each individual ingredient. Our solutions are manufactured in our in-house facility located in Fort Collins, Colorado. Our manufacturing facility is ISO certified, cGMP Certified and FDA compliant.

Yes, every batch of our 2x4 solutions are third-party and clinically tested for efficacy and safety. 

Yes! Our solutions only use 100% natural ingredients, ethically sourced from around the world. In addition, all of our solutions are sugar-free, gluten-free, and non-GMO.

At 2x4, we develop all of our vitamin solutions to work for everyone in your family. Our full range of supplements have been formulated by Doctors and Nutritionists with kids in mind, so that everyone in your home can easily pour, sip, and enjoy the benefits of their vitamins. 

Nutristack® Lipsomal 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.

Love this supplement!

I love this supplement, it tastes great and lasts a long time! I have better energy when I take it consistently and I feel like I don't get as sick as often either. I listen to Courtney's podcast and love that she is putting the truth out there about our health so this supplement was a no-brainer for me!
