Are supplements truly enhancing your health, or are they just hijacking it? In this episode, I bring together two leaders in the health and wellness space—Dr. Jeffrey Bland, known as the founder of functional medicine, and Robyn Openshaw, nutrition researcher and author of “Take Daily: How Supplements Hijack Your Health”—for an honest and eye-opening debate.
We dive deep into controversial topics like the real story behind vitamin C and D supplements, why fish oil and protein powders might contain more than you bargained for, and how industrial processing could affect the purity of your favorite health boosters.
If you’ve ever wondered whether your supplement stack is really serving you or possibly doing more harm than good, this episode is a must-listen. Join me as we explore practical tips for smarter, safer health choices.

| 0:05.0 | You don't want to go eat M&Ms. A lot of you people would never touch an M&M, but you don't know how processed your protein is, and it's the bars and the powders. |
| 0:14.0 | It's a billion dollar industry. |
| 0:15.0 | Protein, you may be consuming 100 or more grams a day. |
