Editor's Take
Natural Stacks isn't your typical supplement company throwing around vague promises about "brain health." These guys actually mean business when it comes to cognitive enhancement, and honestly? It shows.
Founded in 2013, they've built their entire reputation on something pretty rare in the supplement world: complete transparency. We're talking full ingredient disclosure, third-party lab testing, and what they call "open source" formulas. No proprietary blends hiding behind fancy marketing speak-you know exactly what you're getting and how much of it.
Their flagship product, CILTEP, gained serious credibility when poker pro Martin Jacobson credited it for his $10 million World Series of Poker win. That's not just marketing fluff-that's real-world performance under pressure. And speaking of performance, Natural Stacks generates over $10 million in annual revenue with a 40% growth rate, which tells you people are actually getting results.
What really sets them apart is their educational approach. Their YouTube channel has nearly 14,000 subscribers and features over 500 informative videos explaining how their ingredients actually work in your brain. It's like having a neuroscience class with your supplements.
The product lineup goes beyond basic nootropics. They've got targeted formulas for dopamine, serotonin, magnesium gummies for sleep, and they're constantly expanding. Their "Serotonin Brain Food" ranks #1 on Amazon for "serotonin," and "Dopamine Brain Food" ranks #2 for "dopamine"-that's some serious market validation.
But here's what's really impressive: they've expanded from 1,000 to 5,000 retail stores since 2020, landing in CVS, GNC, Sprouts, Whole Foods, Sam's Club, and soon Walmart. That kind of retail penetration doesn't happen unless your products actually work and people keep buying them.
The company operates with manufacturing standards that exceed typical supplement requirements, following cGMP practices and FDA guidelines. Every batch gets tested by third-party labs for purity and potency-something that should be standard but unfortunately isn't in this industry.
The Nutrition Insider gave them an A- grade, noting improvements in stress and mood after sampling their products. That's coming from reviewers who test supplements professionally, not just random customer testimonials.
