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.
Immune System - Nepute Wellness Resource

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

Yes, many products are designed to work together. Stacks are specifically formulated for synergistic effects. However, we recommend discussing your complete supplement regimen with your practitioner, especially if you take medications or have specific health conditions. Your practitioner can guide you on optimal combinations.

“Selfcare as Healthcare” is one of the guiding mantras at Nepute Wellness. It represents the belief that true healthcare starts with empowering you to take an active role in your own healing and your family’s health, rather than passively depending on the traditional sick-care system.

At Nepute Wellness, this means educating you about root causes, providing tools and resources for ongoing wellness, and giving you the knowledge to make informed decisions about your health journey. Our goal is to move you from confusion and overwhelm to certainty and empowerment.

Yes, HSA and FSA cards are accepted for eligible services. Chiropractic care, diagnostic testing, and many functional medicine services qualify. Some products may qualify depending on your plan. Check with your HSA/FSA administrator for specific coverage details. We can provide itemized receipts for eligible expenses.
Yes. Your genetic data is protected under HIPAA guidelines and our strict privacy policy. We do not sell or share your genetic information with third parties. Your data is used solely to generate your personalized health insights.

Yes. During your Day Two Report of Findings, your provider presents a personalized Health Investment Plan that includes care timeline, recommended treatments, and associated costs. We work with patients to find arrangements that make comprehensive care accessible.

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.

My experience at Nepute Wellness has been nothing but great! From the desk staff and MA’s to the doctors; everyone is so nice, professional, and personable. No matter how busy they are, they make an enough to make sure their patients are heard and needs are addressed. They help address you like family, and walk with you on your health journey. Nepute Wellness goes against the grain of our current healthcare model. They not only pinpoint the source of the problem, but help address that cause. NOT the symptoms. I highly recommend Nepute Wellness!

Dr. Nepute and his staff are TOP NOTCH! They are extremely knowledgeable and always happy and friendly. If you want to get to the root of your issues and not just put a bandage on it, this is the place to go. I would drive 2 hours just to go there! I have been to other chiropractors and they just want to push you through. You come here, you get 3/4 different activities to loosen you up before even seeing a doctor. They do it right! They want to fix you!

Dr. Eric Nepute and his staff are exceptional. If you want to get to the root of your health issues, and not just medicate yourself forever, GO SEE DR. E! Regardless of age. My youngest child had digestive and GI issues for years, and after a few months of seeing Dr. Nepute and his staff, my child is healthier, happier and can be a kid again. It doesn’t matter what your health issue is, stress, pain, GI, hormone imbalance, back/neck issues, fatigue, weight gain, cholesterol, high blood pressure, etc. they will get to the bottom of it. I thank God for doctors like Dr. Nepute who are dedicated to HEALTH care, and not just medical care or sick care. They strive to help heal their patients for good, so we don’t have to depend on frequent visits to the doctor for refills and short-term solutions. Thank you Dr. Nepute & Staff. You truly are changing lives every day!
