Spot On!

Peptides are a hot topic, but do you know what they are, how they work, and are legally sold? Dr. Caitlin Dow, PhD, from the Center for Science in the Public Interest (CSPI), is here to tell you what the science actually says about these products. Spoiler: it's not reassuring. We dive into how injectable peptides flooded the market, why people are buying them illegally, and what's missing from the safety equation. Dr. Dow leads the fight against health misinformation, and this episode is packed with the hard truths that some in the wellness industry may not want you to know. Whether you've been tempted to try them, know someone who has, or want to understand the regulatory nightmare behind this trend, this one is a must-listen.

The cannabis beverage industry is booming, but what about the science? That's still catching up. Dr. Tory Spindle, PhD, a leading cannabis researcher at Johns Hopkins University, cuts through the hype and delivers the evidence in this episode. We explore the origins of cannabis production, what the research actually tells us about safety, and the critical factors that shape how these products affect your body, from dose to route of administration, and individual tolerance. Whether you're curious about this emerging trend, concerned about what's in these products, or want to understand how to use them safely (if you choose to), this episode delivers the research-backed answers you need. Dr. Spindle's work has directly informed FDA policy and cannabis regulation, so you're getting expertise grounded in real science, not marketing.

To kick off Season 16, we present one debunked study, decades of vaccine hesitancy, and why it still matters. Dr. Jessie Seiler, PhD, MPH, is back on Spot On! to tackle one of the most persistent health myths of our time: the false claim that vaccines cause autism. Published and retracted in the 1990s, this single flawed study sparked a firestorm of misinformation that continues to shape public fear around vaccination today. But the science is clear, and Dr. Seiler breaks down exactly why. In this episode, we examine the study's critical design flaws, what the data actually showed, and why vaccine innovation remains one of modern medicine's greatest achievements.

That's a rap on Season 15! This season was packed with insightful discussions, led by expert guests on topics such as protein, the correlation between stress and chronic pain, and weight maintenance after GLP-1s. A huge thank you to all our listeners for tuning in to SpotOn!

In this episode, we take a closer look at the growing trend of IV vitamin infusions with Dr. Jessie Seiler, social epidemiologist and Senior Associate at the Center for Science in the Public Interest. Are these wellness drips a legitimate health boost or just expensive hype? We break down what the science actually says about their safety and effectiveness, and when they may (or may not) be appropriate outside medical settings. Tune in for an evidence-based conversation to help you decide if IV vitamins are worth it or best left in the clinic.
