Core4 is designed to work on the core area of your body, which is one of the most vital areas to stimulate weight loss, boost energy levels, and promote optimal health and wellness. Like nuclear fusion occurs in the sun’s core, Core4 creates a synergetic Nutrient Fusion within our bodies to help us lose weight and maintain a healthier, more vibrant life.

The Science of Nutrient Fusion

Scientifically, fusion occurs through the converging of distinctly different elements into the unification of one element, like the blending of copper and zinc creates brass. As it has become apparent in the field of science, the combining of different elements creates an amazing outcome. Applying this knowledge to the field of nutrition, Cal Nutrasciences (CNI) is the first company to use the science of fusion to create a proprietary Nutrient Fusion process.

Using this advanced process, CNI is able to blend distinct and very effective nutrient components into revolutionary Nutrient Fusion systems, such as the CORE4 system. Why is Nutrient Fusion Important? Because it produces BETTER and MORE results! Nutrient Fusion creates a synergetic effect between each individual component, fusing them into a unified system scientifically developed to produce never-before-seen results.

The CORE4 Experience

Here's what people are saying about the Core4 System...

I have been an athlete most of my life and have used all of the best protein powders over the years... ALL OF THEM.... and I swear, LEAN is the best I have ever had, bar none! I could tell within 48 hours that there was something special about this product! Thank you, thank you, thank you!

In less than four days I’ve already lost 5 pounds! This is the best weight loss I have EVER experienced because I’m losing it all around my stomach area! Believe me, once you experience CORE4 you will know we have the BIGGEST opportunity on the planet to help people with health challenges!

After having my children, I could never seem to regain my pre-pregnancy weight—until I took CORE4. Within 9 days of using the CORE4 system, I lost 9 pounds and the baby fat is almost gone!!! My skinny jeans are now baggy! Thanks CNI for creating this amazing group of products that are shrinking my stomach, in a healthy way! CNI CORE4… AMAZING COMPANY… AMAZING PRODUCTS… AMAZING RESULTS!

I am a Registered Nurse with 23 years of Critical Care experience. During the past 16 years, I have been involved in nutritionals and for the last seven or so years, I owned and operated a wellness/weight loss center. My weight loss program was very successful, but didn't come close to what I see happening to myself and others with CORE4. This is simply the best combination of products I have ever seen! I have lost 22 pounds over a 5 week period and my blood sugars have improved to where I could reduce the amount of insulin I need to take.

I have been on the CORE4 System for only 3 weeks. WOW! I have already lost 12 pounds and I’m down one pant size. I really only needed to lose about 15 pounds so I'm almost there! Another fabulous benefit for me has been that it has helped me with a digestion problem that I have had for a long time. Eating is once again enjoyable! All of the products are wonderful, but LEAN is really a big hit at my house. It’s a great tasting smoothie especially when mixed with different fruits, and it satisfies the appetite and reduces food cravings!

CORE4 is so easy! I began CORE4, 10 days ago...since then I have lost 8 pounds. My snacking has stopped, my digestion has improved, and I find myself excitedly keeping track of my weight loss. I think what pleases me the most is that once I lose all of my excess weight, I will have adopted a regimen that I can follow for life. Thanks to CORE4, I KNOW that I am on track to make it happen!
