#442: The High-Performance Guide to Supplements With Kyal Van Der Leest
Today, I’m joined by Kyal Van Der Leest, an innovative naturopath, nutritionist, and founder of LVLUP Health, whose formulas are changing the way we think about effective supplementation. Kyal’s journey is deeply personal: from caring for his mother through a long battle with cancer, to overcoming his own intense health struggles with mold illness. These experiences led him to push past superficial fixes and dig deep into what really works for healing and optimizing the body.
In our conversation, Kyal and I get blunt about the supplement industry—why most “stacks” actually set people back, how to avoid the quality traps, and the huge difference it makes when you focus on underlying mechanisms instead of just chasing symptoms. He breaks down his hybrid approach, blending the best of naturopathy, biochemistry, and smart biohacking to build formulas with results you can feel, and dives into practical strategies for brain health, hormone balance, gut repair, and more.
If you’ve ever felt overwhelmed by supplement choices or wondered whether you’re truly supporting long-term longevity—not just quick wins—this episode is packed with the insights, honesty, and real-world experience you need to reset your approach.
