Understanding Your Immune System

An evidence based overview of how your immune system works and why supporting immune health requires a root cause, whole person approach.

About This Resource

Your immune system is a complex network that protects your body from infections and disease. This resource draws from NIH research to explain immune function in a clear, accessible way.

Why We Share It

At Nepute Wellness, we approach immune health as part of a comprehensive, root cause wellness strategy. Understanding how your immune system works is the first step toward supporting it effectively.

Your Immune System: More Than Defense

Most people think of the immune system only when they get sick. But research has shown that immune function is deeply connected to overall health, influencing inflammation, healing, energy, and even mood. At Nepute Wellness, supporting immune health is not just about avoiding illness; it is about building a resilient foundation for total wellness.

How the Immune System Works

The immune system consists of two main branches: innate immunity (the rapid, general defense you are born with) and adaptive immunity (the targeted response that develops over time). Together, these systems work to identify, target, and neutralize threats while minimizing damage to healthy tissue.

Key components include white blood cells, antibodies, the lymphatic system, the spleen, bone marrow, and the thymus. The gut also plays a critical role: research published in Clinical and Experimental Immunology suggests that approximately 70% of immune cells reside in the gastrointestinal tract, reinforcing the gut-immune connection.

Root Causes of Immune Challenges

When immune function is compromised, the root causes often extend beyond simple exposure to pathogens. Research suggests several common factors that may influence immune health: chronic stress (which may suppress immune function), poor sleep (which is critical for immune cell production), nutritional deficiencies (especially vitamins D, C, and zinc), gut microbiome imbalance, environmental toxin exposure, and chronic inflammation.

This is why a root cause approach matters. Simply boosting the immune system without addressing underlying factors like stress, gut health, or toxin burden may not produce lasting results.

The Nepute Wellness Approach

Our approach to immune health begins with comprehensive assessment: “Test, Don’t Guess.” We look at blood panels, gut health markers, stress indicators, and nutritional status to understand what may be affecting your immune function at the root level. From there, we develop personalized strategies that address the underlying causes rather than just the symptoms.

FAQ

Frequently Asked Questions

Absolutely. We work alongside your existing healthcare providers. We can share test results and treatment plans with your primary care physician, specialists, or other providers with your permission. Our approach complements conventional medicine – we focus on root-cause optimization while your doctors handle acute care and medication management.

Yes, BioLimitless products are available for purchase directly through biolimitless.com without requiring a Nepute Wellness examination. However, our “Test, Don’t Guess” philosophy means that products recommended after proper testing are targeted to your specific biochemistry rather than being a general guess.

If you want to maximize the value of supplementation, consider starting with a consultation so your provider can identify exactly what your body needs based on blood work, brain mapping, and other diagnostic data.

If you’re not seeing expected results, we reassess. This may include follow-up testing to see what’s changed, adjusting your protocol, or exploring other factors. Health optimization is a process, and sometimes we need to adjust our approach based on how your body responds. We’re committed to finding what works for YOU.
Exam costs vary by package: Basic Examination is $199 ($50 deposit), Comprehensive Functional Insights is $399 ($50 deposit), and Human Performance Exam is $1,299 ($50 deposit). Virtual consultations range from $42.42 (Basic) to $420 (Elite). Remaining balances for in-office exams are paid on exam day. See our Solutions page for complete pricing.
Fasting requirements depend on which tests are included. For blood panels, fasting may be required (typically 8-12 hours). For HRV testing, avoid caffeine and exercise 2-4 hours before. For thermography, avoid hot/cold beverages, exercise, lotions, and deodorant 4-6 hours before. Detailed preparation instructions are sent after booking.

IV vitamin therapy delivers essential nutrients directly into your bloodstream, bypassing the digestive system for more efficient absorption. At Nepute Wellness, IV therapy may be recommended as part of your personalized care plan based on your test results.

Common IV formulations may include vitamins, minerals, and amino acids tailored to address specific deficiencies identified through blood work and other diagnostics. This therapy is designed to support your body’s healing process alongside other modalities like corrective chiropractic and neurological balancing.

I have been coming to your wellness center for over 2 years now and have been excited and pleased to have Dr Eric available to discuss my changing health needs. His encouragement and advice I found very good. His pleasant delivery is welcome. After our meeting I took advantage of most of your wellness equipment and chiropractic services. There is always a great adjustment and a nurse practitioner to use more direct help to target areas as identified by the chiropractors when needed.

Doc and his staff have completely changed my life. I have been suffering from chronic pain and inflamation. I have been going there for several years now. Dr. Eric, Dr. Rachel, Dr. Patric and staff have been extremely helpful. I have learned how to stay healthy and how to heal. I am in my sixties and very active. I plan on staying that way with the help of Nepute wellness. Over the years I have used traditional medicine only to be given pills that mask the pain. Neputi wellness has given me a holistic path to getting heathy and staying well. This type of wellness takes time. Have patience. You will be amazed ! Update 8/1/25 I just wanted to share that I have been taking the biolimitlist Neuro Reboot. My chronic pain has decreased to almost nothing. Especially in my lower back. This has allowed me to live the active life that I am accustomed to. I have been trying to avoid medications at all costs but was starting to give in. This product is working well. In my case, it took almost 60 days. But from then on, it was amazing. I noticed the first week I was sleeping better. The pain in my joints was starting to ease. My back, however, took a longer time. In my opinion, it is worth the money. And many thanks to doc and his amazing staff!

I’ve been a patient for five years. The staff is second-to-none! It’s a family atmosphere focused on nutrition, supplementation, and getting motion back into your body. I recommend Nepute Wellness to anyone with goals centered on long-term wellness because, as Doc himself reminds his patients: health isn’t only about how you look nor how you feel, but how you function.

My family has been going here for years and are thankful for everyone there. Dr. Nepute stands by his oath in caring for people no matter your issue instead of putting a bandaid on it. I find the reviews funny that condemn him for recommending supplements yet have no problem with doctors prescribing medicines that cause side effects so they can add another medicine for that side effect! Exactly what big pharm want.all of us drugged up for life. I trust Dr. Nepute and am thankful to have found him.
