Summary
On episode 332 of 40+ Fitness, Coach Allan sits down with Dr. Stephanie Gray, a functional medicine physician who runs a clinic in Cedar Rapids, Iowa focused on integrative medicine and hormone replacement, and author of Your Longevity Blueprint.
Stephanie explains why conventional medicine, what she calls the “fire department approach” using only drugs and surgery, treats symptoms without finding the root cause, while functional medicine digs into nutritional deficiencies, thyroid function, and sex hormones to explain why someone feels off in the first place. She walks through why modern food, medications, and lifestyle leave most people more nutrient depleted than prior generations, and what to watch for with key vitamins and minerals like B vitamins, vitamin D, vitamin C, and magnesium.
The conversation also covers why standard thyroid testing (TSH alone) misses the real picture, why both men and women should have their sex hormones tested, and how to find a functional or anti-aging medicine provider if a regular doctor isn't the right fit for optimizing health rather than just treating illness.

Key Takeaways
- Conventional medicine is built to put out fires, not find root causes. Stephanie compares it to a fire department with two tools, drugs and surgery, that manage a symptom like fatigue without asking why the fatigue exists in the first place.
- Modern food is far less nutrient dense than it used to be. Depleted soil, produce picked days or weeks before it's eaten, high heat cooking, and processing all strip nutrients out of food compared to what earlier generations ate, even from home gardens.
- Common medications and habits deplete key nutrients. Statins deplete CoQ10 (often causing the muscle pain patients report), and birth control depletes B vitamins and magnesium; alcohol, caffeine, smoking, and stress do the same.
- B vitamins support adrenal function and energy. They're often the first supplement Stephanie tries with a tired patient, especially athletes, and low levels can also show up as tingling or burning nerve symptoms.
- Vitamin D affects bone density, immunity, and mood. Low vitamin D raises the odds of getting sick through flu season, is tied to fractures even in young patients, and is linked to seasonal depression when sunlight drops off in winter.
- Magnesium may be the most important mineral in the body. Stephanie ties it to more than 300 enzymatic pathways, using it to calm anxiety, ease restless legs and cramping, support sleep, relax the bowels, and support hormone production.
- Standard thyroid testing (TSH alone) misses the real story. Stephanie calls TSH “too slow to help”: by the time it's abnormal, free T3 and T4 may already be low, and doctors rarely check free T3, reverse T3, or thyroid antibodies, all of which give a fuller picture.
- Sex hormone decline is real and measurable in both men and women. Men lose 1 to 5 percent of their testosterone per year between ages 30 and 70, women can lose half their testosterone production between 20 and 40, and low progesterone in women is often mistaken for anxiety or depression and treated with medication instead of being tested.
- Get a full panel even without obvious symptoms. Stephanie recommends testing nutritional and hormone status every one to two years regardless of how you feel, since what feels “normal” (grogginess, poor sleep, needing coffee to function) often isn't, and a functional or anti-aging provider can be found through directories like A4M or IFM if a regular doctor can't run the testing.
“Know there's hope. If you don't feel right, there's an answer. Find a provider who can help you get those answers.”
