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.

I have had problems with digestion for years. I am a healthy 62 year old Dental Hygienist and live a healthy active life. However my stomach issues have been there for years. Being a healthcare provider, I’m always cautious and leery of claims of boosting health energy etc. That was until I started following Dr Napute’s and vice, and watching his videos, I finally got the Digestive Enzymes and Warrior Water! Oh my goodness! These 2 products have changed my life and stomach forever! Almost completely eliminated my heartburn and night time acid reflux, I feel better, more energy, sleep better, the list goes on! I will never go a day without these 2 products! Thank you Dr Napute! Just so you know, I often tell my dental hygiene patients about you! Thank you Dr.! God bless you for spreading the news about these great products and educating us about healthy choices! Blessings, Lisa B. San Diego CA
