Achieving optimal health starts with consuming the right nutrition and putting in the work. We believe that when you power your body with the correct nourishment and exercise, the body’s functions are supported. This can allow the body to naturally generate energy, clean cells, get rid of waste, and defend your health. Our perspective is that taking responsibility for the health of your body, mind, and spirit is key to personal progress.

We stand for freedom—including our god-given birthright to be strong, brave, and healthy. This fierce approach to life is integral to being a Rebel Lion. Greeting each day with a roar, we’re driven to see everyone across the globe feel fierce—and fearless—in their bodies, minds, and spirits. Learn more about our mission.

We brainstormed the most urgent, solvable issues facing us today. Toward the top of a very long list, we put “health.” As a result, our Fierce products were born. 

Another clear priority was “censorship” and our freedom to speak truth. We created Rebel Lion Threads so if you can’t say it, you can wear it. Broadcasting these messages to the world through your clothing can spark meaningful conversations and create solidarity with like-minded individuals. Shop apparel →

Most supplements are mixtures of ingredients that affect the body’s functions in a random fashion, which may do more harm than good. This problem can be particularly serious with so-called immune support products.

Why? Because our immune systems are incredibly sophisticated, as they not only help to protect us against microbes, viruses, and cancer, but also support our natural healing processes. If these systems overreact, you could experience acute life-threatening conditions and/or chronic disabilities. 

So, knowing what to take is essential. Our supplement is a carefully calculated synergy of intentional ingredients that are designed to help your immune system.

The formula was designed by evaluating functions executed by specific subsets of specialized T cells (Th1/Th2; Th17/Treg)—and selecting ingredients that help maintain optimal ratios between them.

What’s the specific technology used? The patented, proprietary technology helps to identify interactions between functions required to maintain the health of an immune system that protects all cells, tissues, and organ systems of the human body.

Emergence is a property of living things that results from interactions between all their parts. You could call this a “holistic” perspective. This can’t be described by summing up properties of individual components. Therefore, typical supplements—whose formulas look at effects from an individual ingredient or function level—are unlikely to support health at a whole-body level.

Our patented product-design technology is based on evidence. This means that the efficacy assessment of Fierce Immunity is built upon thousands of experiments, as well as clinical trials conducted all over the world in the past 80+ years, which are archived in the national library of medicine, PubMed.
