The Rainbow Challenge™


Vibrant, colorful foods aren’t just beautiful to look at. They also benefit our bodies, helping us run better, feel better, and maintain better health in the long term. Research confirms that intaking all these colors from plants makes a difference in our overall health and that a variety of sources for each color, more often, aligns with better health outcomes. Through BNP’s Rainbow Challenge, you’ll identify the color(s) you don’t get in as easily and discover ways to overcome challenges to get those colors in more often.  With help from your personal wellness coach, you’ll discover a technicolor, antioxidant-packed world of health and wellness.

A Proven 4-Step Process

Designed For You by Award-Winning Practitioners

Investigate: Explore You

You are the key ingredient in this recipe for better health. We place a strong emphasis on understanding you, encompassing your goals, existing preferences, and the reasons behind those choices. We also pay close attention to how your body reacts to various stimuli, (we call these “experiments” but don’t worry, they happen at home not in a lab!). Phase activities: Data sharing, experiments; BNP Team™ support

Develop: Your Personalized Plan

With the exceptional expertise of The BNP Clinical Team™, spanning over 25 years, we thoroughly assess your data, results, and objectives. From this evaluation, we craft your initial roadmap, providing you with a range of tailored options to navigate your journey efficiently toward your desired goals. Phase activities: review, develop & plan sharing; agree to next steps; Clinical & BNP Team™ support

Implement: Take better step(s)

Let’s see how you and your body respond to the steps outlined in your plan. What’s doable (and not), what helps you feel better (and doesn’t). Your feedback is essential to developing a truly personalized plan that works. Phased activities: experiments, coaching live sessions, messaging, clinical private feedback, clinical live group sessions; BNP Coaching™, Clinical & BNP Team™ support

Optimize: Continue winning

Adapt your health journey based on your body’s responses. Utilize tests, evaluations, and experiments to fine-tune your approach. Adjust goals as needed, knowing that health is ever-changing, requiring a truly personalized plan.

More Pathways to Better Health

Water Challenge

Water escorts so many of the nutrients found in a better nutrition rainbow so it’s essential we get enough of it daily – along with a rainbow of colors. Challenge yourself to not just eat better but hydrate better too—and create lasting habits that support your body.

Omega 3 Optimizer™

Healthy fats escort many of the key plant nutrients found in the colors of the rainbow to where the body needs them. Make sure your fat choices are helping get this important work done and are the better choices for collaborating with the colors to arm your body for success.
