The Supplement Industry Is Lying to You with Robyn Openshaw
Most of us assume supplements are helping us.
After all… they’re marketed as essential for filling nutrient gaps, supporting immunity, and optimizing health.
But what if that assumption deserves a closer look?
In this episode of the ReThink Health Podcast, I sit down with Robyn Openshaw (author, researcher, and founder of GreenSmoothieGirl) to pull back the curtain on the supplement industry.
What she uncovered after years of deep research may completely change how you think about the pills in your cabinet.
From synthetic vitamins to fish oil, collagen, and beyond, Robyn explains why not all supplements are created equal… and why many may not be delivering the benefits people expect.
You’ll learn:
-
Why most supplements on the market are synthetic (and what that actually means)
-
The surprising connection between the pharmaceutical and supplement industries
-
Why isolated nutrients may not replicate the complexity of whole foods
-
What’s really behind common supplements like vitamin D, B12, and collagen
-
Why many fish oil supplements may be oxidized or ineffective
-
The difference between correlation and causation in nutrition research
-
How soil depletion and modern agriculture may contribute to nutrient deficiencies
-
Simple ways to evaluate supplement quality using better questions and tools
If you’ve ever wondered whether what you’re taking is actually helping your health, this episode will completely change how you think about supplements.
