For decades, the supplement and wellness industry operated on a simple premise: if it tastes good, sells well, and doesn’t kill anyone, it’s good enough. Artificial sweeteners became the industry’s great bargain, a way to deliver palatable products without the caloric guilt of sugar. Sucralose became so embedded in the category that questioning it felt almost quaint. The public was told it was safe, then the science caught up.
Over the past several years, a growing body of peer-reviewed research has complicated the industry’s comfortable consensus on artificial sweeteners. Studies have linked sucralose, a compound derived from sugar through a process that substitutes chlorine molecules, to disruptions in the gut microbiome, measurable spikes in insulin response despite containing no sugar, and downstream effects on blood sugar regulation that may actually trigger the cravings it was supposed to eliminate. The very product sold as a guilt-free alternative appears, in meaningful ways, to undermine the health goals of the people consuming it.
For most supplement companies, this is an uncomfortable inflection point. Reformulating is expensive. Consumer habits are sticky. Margins on naturally sweetened products are thinner. However, for a small cohort of operators who made the bet on natural formulations years ago (before it was commercially obvious) the reckoning is a tailwind.
Kevin Gundersen is one of them.
Gundersen, the founder and driving force behind Gundersen Enterprises, a health and wellness holding company with revenues exceeding $100 million annually, has spent the better part of a decade building his portfolio around a single conviction: that consumers would eventually demand products that are not merely safe, but genuinely clean. No artificial sweeteners. No synthetic fillers. No compromises dressed up as innovations.
It is a thesis that now looks prescient.
Gundersen Enterprises operates across multiple brands in the natural supplement space, with Gundersen himself having personally formulated and launched over 250 products across his career. The holding company’s portfolio spans supplements, meal preparation and delivery, skincare, cutting edge wearable fitness trackers, and soon athletic apparel. This is a deliberately integrated ecosystem built on the idea that health is not a vertical, it is a lifestyle. Among his companies, NLA For Her established itself as a dominant brand in female-focused supplementation, while LIV Body built a loyal following in the natural performance category.
At the center of the portfolio’s supplement philosophy is an ingredient category that Gundersen identified early as the next major wave in consumer wellness: gut health.
The gut microbiome — the vast ecosystem of bacteria, fungi, and other microorganisms living in the digestive tract — has emerged as one of the most prolific frontiers in health science. Researchers now understand that the gut is implicated not only in digestion, but in immune function, neurological health, metabolic regulation, and even mood. The oft-cited phrase “the gut is your second brain” has moved from wellness blog shorthand to a framework with serious clinical backing. Disruptions to the gut lining — a phenomenon known as intestinal permeability, or informally as “leaky gut” — have been associated with systemic inflammation, cognitive fog, and a range of autoimmune conditions.
Gundersen saw this coming before it became a mainstream conversation.
Several products across his portfolio incorporate an ingredient called CoreBiome, a form of tributyrin shown in research to support the integrity of the intestinal lining, helping, in practical terms, to prevent compounds from the gut from migrating into the bloodstream and crossing the blood-brain barrier. It is the kind of ingredient decision that doesn’t move product on a shelf the way a flashy stimulant might, but speaks to a deeper formulation philosophy: build for outcomes, not marketing copy.
“Gut health is the fastest growing supplement category in health and wellness,” Gundersen has said, “and I think it’s going to absolutely skyrocket over the next few years…for good reason.”
The market data supports the outlook. The global gut health supplement market has expanded rapidly, driven by consumer awareness and the broader mainstreaming of microbiome science. However, Gundersen’s edge is not merely that he is in the right category. It is that he has built operational infrastructure to move quickly, with a formulations track record that gives his brands credibility that newer entrants cannot manufacture overnight.
The next phase of Gundersen’s ambitions extends beyond making an impact in the health and wellness industry. Later this year, he will be launching Revenue Rush University, a training platform that teaches entrepreneurs and business owners the operational systems and marketing frameworks behind his nine-figure enterprise. In an industry crowded with courses taught by people who have either never run a successful business, Gundersen’s differentiator is straightforward: he is teaching exactly what is working at a 9 figure scale in the current market today.
For an industry standing at an inflection point between what worked and what’s next, that kind of operational credibility is, increasingly, the only kind that matters.
