For over a decade I have practiced root-cause medicine in Frisco. Many greenwashed versions that do not provide genuinely functional or holistic solutions have come and gone. I would be honored to receive your vote in Functional Medicine under Healthcare!

We're living in strange times, and stressors are everywhere: work deadlines, social media notifications, financial pressures, and global unrest. I often see patients who are doing everything right and still feel wired, exhausted, and off. The missing piece can be the nervous system stuck in a chronic stress mode.

When your nervous system gets stuck in "fight or flight," the downstream effects are real and measurable: disrupted sleep, blood sugar swings and cravings, cognitive fatigue and brain fog, a gut lining that becomes increasingly permeable, or even shrinking hippocampus (yes, chronic cortisol literally changes your brain).

The good news is your nervous system is remarkably plastic. In my latest blog post, I walk through how stress can be measured along with the wearable and supplements I recommend most often to support the nervous system.

Everyone talks about the medical industry profiting off the sick, but we need to talk about the explosion of online lab companies. Your medical provider or the health influencer you follow might be making $100 every time they send you to certain labs, and that financial conflict of interest is rarely disclosed.

If a provider is profiting off every test they recommend without transparency, that’s not healthcare; it’s a business model. On top of that, an automated, AI-generated lab report is no substitute for real clinical guidance.

You deserve better. To genuinely overhaul our medical system, providers must be transparent about where their incentives lie, and patients deserve to have all the facts before they decide.

I want to briefly address the confirmation hearing for Dr. Casey Means as the nominee for Surgeon General, the state of our healthcare system, and how we can move forward to effect change in that system. Let’s make the most of this opportunity! Put politics aside, open your hearts and minds, and let’s all be part of the solution.

Think your turmeric is doing what the label promises?

🧪 Independent testing has found that some turmeric supplements fall short of their claims, which means that you may not be getting the amount or quality you expect. Additionally, this last week a popular turmeric supplement was recalled for reports of mold contamination.

💡 And this isn’t just true for turmeric. It’s true across the supplement aisle. Quality, sourcing, and testing matter! Unfortunately, labels don’t always tell the whole story.

So what can you do?
✅ Become an informed consumer.
✅ Ask questions about sourcing, testing, and bioavailability
✅ Work with a provider who does the same.

🤝 I believe in a collaborative, partnership-based approach to care, which is why I only use supplements that meet strict quality and testing standards.

🩺 Functional medicine isn’t “alternative”.
It’s evidence-based, personalized, and designed to complement conventional care.

I sat down with Yvonne Brown of Frisco Style magazine to discuss functional medicine’s root-cause approach.

？Should you do a detox? Do you need to?

I think starting the year with a proper metabolic detoxification is a great idea; if you understand your state of health and you are supported in that appropriately.
You could do a detox without a product, but that’s a lot of food.
To get the clinically pertinent, impactful component of any particular food - the amount that you’d have to ingest is usually greater than what you could possibly eat. 🥗🥦

Over time, toxin build-up, stress, and inactivity can be detrimental to health and longevity.
💡 This is why I recommend the Dynamic Detox program. It’s a nutritional plan designed to support your body’s natural metabolic detoxification processes (which in turn encourage alkalinity) while providing ample fuel for both cleansing and other daily activities, thereby promoting overall well-being. While many “detox” protocols are convoluted and hard to follow, this program features a step-by-step game plan for every day, including exactly what to eat, what to drink, and how to properly use Dynamic Detox and Detox Support capsules for optimal efficacy and results.

📌 The program is for anyone who wants to revitalize and rejuvenate their mind and body every few months. Even if you eat a relatively healthy diet and exercise regularly, the program is a great way to “start fresh” and get you back to feeling and functioning your best.

📌 The kit contains Dynamic Detox powder, Detox Support capsules, 1 shaker cup, plus a clear step-by-step program guide and a shopping list so you know what to eat, what to drink, and how to properly use Dynamic Detox and Detox Support capsules for optimal efficacy and results.

Have you ever had a "weird" reaction to a medication? It’s not in your head, it’s in your DNA.

Most people think detox is just clearing out toxins, but real Phase 1 detoxification happens via your Cytochrome P450 enzymes, which are encoded in your DNA. These enzymes dictate how you metabolize everything from prescription drugs to the food you eat. That’s why some medications will come with food warnings.

If you’re considering a detox, don’t just use a product your sister-in-law sells you. I get asked all the time which detox I recommend, and my go-to is Dynamic Detox by NutriDyn. It’s one of the few that’s clinically active and impactful, comes with a clear plan, and is dosed to actually work.
