Traumatic Brain Injury (TBI)—whether from a fall, accident, or sports impact—can change everything in an instant. What you do in the first hours and days after the injury can shape the entire recovery journey.
"TBI: What to Do Immediately After" is the ONLY resource that combines documented neurological protocols with nutrition-based strategies to help stop the progression of chronic TBI and concussion symptoms.
​
🚨 1. Act Fast—Every Minute Counts
Recognize the signs of TBI early:
• Headache, dizziness, nausea
• Confusion or memory loss
• Slurred speech or vision changes
• Loss of consciousness (even briefly)
Immediate medical evaluation is critical. The book emphasizes: “Time is brain—delay is damage.”
🧠2. Support the Brain Neurologically
This book outlines specific neurological and dietary interventions that must be used to stabilize brain function and reduce inflammation.
​
🧠3. Even if its a FOOTBALL injury ,fall or car accident, 1/3 of people will not recover. Don't let your loved ones suffer....You need this book!

Functional medicine is a **patient-centered approach** to healthcare that focuses on identifying and addressing the root causes of chronic illnesses. Unlike traditional medicine, which often treats symptoms, functional medicine looks at the whole person—considering factors like nutrition, lifestyle, genetics, and environmental influences—to create a personalized treatment plan. Why do you have a problem, and why won't it go away? This is the BEST way to get better.
It's truly disheartening to see people suffer for years without finding relief. Functional medicine aims to change that by spending more time with patients to understand their unique health challenges and working collaboratively to develop effective, long-term solutions.
We use out of the box thinking, and can order test your many other doctors have missed, or won't do because of insurance constraints, being to specialized to see the BIG PICTURE.

What is epigenetics?
Epigenetics involves changes in gene activity that don’t alter the DNA sequence. Essentially, it’s how external factors can affect which genes are active and to what extent. Epigenetic markers, like DNA methylation, help us understand these changes.
​
What is biological age?
Biological age measures your body’s cellular and molecular age, which can differ from your actual age. It can change due to lifestyle choices, health factors, and other influences. Measuring biological age through methylation is highly accurate and predictive of future health, disease risk, and even lifespan.

I hope you reach out soon.

The gut and brain are intimately connected through the vagus nerve, which means stress can directly affect your digestive system. Chronic stress can shift the balance of gut bacteria, increase inflammation, and compromise digestion. On the flip side, an imbalanced gut can worsen stress and anxiety, creating a vicious cycle. This is why managing stress and nurturing your gut simultaneously is essential for overall well-being. If this isnt fixed first, nothing can help you! Find out why here!



Testimonials

I am so grateful that I listen to a friend who suggested I go to Dr. Jung. I have been his patient now for over 20 years. he has helped me when no other doctors could. I've had numerous issues over the past 20 years that he was able to fix. Recently he started me on a new treatment for my asthma, which is working awesome. I’ve had asthma for over 50 years and my breathing has never been better. He's always researching new things to help his clients and he stays current on new treatments. He is an amazing doctor with a wealth of knowledge. Thank you Dr. J

Dr. Jung is an AMAZING doctor. I am so thankful that I was referred to him!! At first I was a little skeptical about going to him at first, because I have been to numerous doctors and specialists over the past couple years without any relief! Most doctors ran the same unnecessary tests and just gave me pills to EASE symptoms, which ended up hurting my body even more.. The previous doctors told me my results were normal, even though I did not feel like myself. It wasn’t until I met Dr. Jung’s online that my life changed.
