#440: The Ultimate Supplement Checklist BEFORE You Buy: Safety, Quality, and Evidence-Based Picks | SOLO With Nat Niddam
Today, I’m flying solo to tackle a topic that’s essential for anyone invested in their health: how to truly vet your supplements. With new products hitting the shelves daily and wellness marketing louder than ever, it’s easy to get swept up in the latest hype—but more isn’t always better, and sometimes it can actually make things worse.
In this episode, I break down the six key filters I use before adding any supplement to my routine, from understanding your baseline biomarkers to decoding red flags in marketing language like “studies show.” I dig into common pitfalls—like why “natural” doesn’t automatically mean safe, the real risks of fat-soluble vitamin toxicity, and how to spot quality with third-party certifications. I’ll also get super practical about bioavailability, dosage traps, and checking supplement-drug interactions so you’re not working against yourself.
If you want a clear, no-nonsense framework and an actionable checklist for deciding what’s truly worth your money and your health, this episode will give you the tools to make smart, empowered choices for your longevity journey.
