538. Does T4 - Synthroid Cause Cancer?

Podcasts
Oct 08, 2025

 

Is your Synthroid (T4) prescription quietly sabotaging your health or maybe even worse? Is it hiking up your cancer risk? In this episode, I rip apart the social media fear-mongering and take you on a science-backed deep dive through the headline making claims about Levothyroxine, Synthroid, and all things T4. You’ll hear the truth behind those scary “T4 causes cancer” statements, what the research actually says, and why so many docs lean on T4-only treatments that can leave you fat, foggy, and, yes, increased risk for cancer if they’re not paying attention to critical lab markers like reverse T3.

I'll break down the difference between T4, T3, and why reverse T3 (the notorious antithyroid hormone) matters way more than your doctor might admit. Learn how a sluggish thyroid protocol can suppress your immune system, fuel cancer-promoting pathways, and what you can do about it. If you’ve ever worried about your morning thyroid pill or wanted legit answers that empower rather than terrify, this episode is your no BS guide to optimizing your thyroid and putting another layer of armor between you and “the big C.” Block out the nonsense, let’s get you educated on T4 medications.
