10 Reasons Why Your $200/Month Supplement Stack Can't Stop You From Getting Sick (And What Actually Works)

1. It Addresses the Root Cause (Not Just Symptoms)
You pop vitamin C at the first tickle in your throat. Zinc lozenges every few hours. Elderberry syrup by the spoonful. But next month? Same cold, same routine.
The Immune Fortress works differently: it rebuilds immunity where it actually lives—your gut. Bio-Avail Colostrum+ seals your gut barrier with immunoglobulins, growth factors, and lactoferrin. Biome Protect optimizes the microbiome with FortiPhage™ bacteriophages, LactoSpore® probiotics, and tributyrin to strengthen intestinal integrity. Together, they restore the gut-immune axis that controls 70% of your immune function. Instead of temporarily boosting a broken system, it fixes why your system keeps failing.
"I have been using Adapt Naturals Colostrum for about 9 months now and the difference I am experiencing in my overall health has been amazing. Having a low immunity I have always been susceptible to catching every cold, flu, and virus out there. Especially being with my granddaughter who would bring every germ home from daycare! I have not been sick in the past nine months. This is HUGE for me." – Penny K., verified buyer

2. Built on 20+ Clinical Studies (While Most Immune Supplements Guess)
Most immune supplements are based on tradition and marketing—not clinical research. Immune Fortress is different.
The ingredients aren't wellness trends—they're backed by 50+ peer-reviewed studies showing significant support for immune and respiratory health. Meta-analyses demonstrate colostrum supports upper respiratory health across all ages. Wellmune® beta-glucan has been studied extensively in stressed adults, athletes, and older populations for immune support. Lactoferrin supports the body's natural defenses. LactoSpore® Bacillus coagulans has been clinically studied for supporting healthy immune responses.
This isn't guesswork or marketing hype—it's real science showing these ingredients support your body's natural immune function at the doses included in Immune Fortress.
"My husband and I both take a daily dose and feel it has kept us healthy even with exposure to sick grandkids a few times. I know it has given me some relief from painful joints brought on by cancer treatments. My husband has a debilitating autoimmunity (LEMS) and using Adapt colostrum helps with his inflammation and energy levels." – Larry Teal, verified buyer

3. Protects You When Everyone Around You Is Sick
You brace yourself every fall. Your kids bring home every school bug. Your coworkers cough without covering. You're the first to catch it, the last to recover.
That's not bad luck—it's a compromised gut-immune axis. When your gut barrier is damaged, pathogens slip through. When your microbiome is imbalanced, your immune system can't respond properly. Immune Fortress creates a multi-layered defense: colostrum's immunoglobulins bind to pathogens, lactoferrin blocks microbial growth, beta-glucan trains your innate immune cells to respond faster, and the complete gut support ensures everything works as designed. Users report staying healthy while everyone around them falls sick.
"I am the only one in my circle who hasn't gotten sick this season. My husband has been sick for the last month and a half, we went to a child's party with 10+ kids, and I've been around other sick individuals in public. I have not gotten sick! I relate it to the colostrum." – Meg K., verified buyer

4. Costs 75% Less Than Your Current Immune Stack (And Actually Works)
Add up what you're spending: Vitamin C supplements ($40/month), zinc and elderberry ($40/month), emergency immune packets ($30/month), probiotics ($60/month), doctor visits when you get sick anyway ($150-200 per illness), lost wages from sick days ($200-400 per day).
You're spending $170+ monthly on supplements that don't work, plus hundreds more when you inevitably get sick. That's $2,000-3,000+ per cold season.
Immune Fortress replaces your entire medicine cabinet with two products that actually address the root cause—for $61-89/month with subscription. And because it works, you're also saving on doctor visits, medications, and lost income from sick days. The math is simple: real immunity costs less than fake protection.
"I am a Functional Nutrition Counselor who specializes in Gut Health and digestive issues. When I saw the ingredients in Biome Protect I was floored. How did you put 4 of my foundational supplements into ONE? Adding up what I spend on each of these separately, I am going to be saving so much money every month." – Rebecca Arsena, verified buyer

5. Created by Someone Who Treated "Impossible" Immune Cases for 15+ Years
You've tried everything. Handfuls of supplements, elimination diets, immune protocols from the internet, even prescription medications. Nothing worked because they addressed symptoms, not the root cause.
Chris Kresser didn't create this in a lab based on theory—he developed it after treating hundreds of patients who got sick constantly despite taking every immune supplement on the market. After healing his own severe digestive illness, he spent 15+ years in clinical practice discovering why traditional approaches fail: they ignore the gut-immune axis where 70% of immunity lives.
He trained 3,000+ practitioners, wrote a New York Times bestseller, and pioneered the functional medicine approach to immunity. Immune Fortress combines his personal healing journey with clinical expertise—not marketing theory.

6. No More Living in Fear During Cold Season
You obsessively wash hands. Avoid sick coworkers. Cancel plans when someone sniffles. Keep kids home at the first sign of illness. Live defensively instead of freely.
That constant vigilance is exhausting—and it doesn't even work. You still get sick because you're trying to avoid exposure instead of building real immunity.
Immune Fortress lets you stop living in fear. By rebuilding the gut-immune axis where 70% of your immunity lives, you can live normally while your body handles the exposures that used to make you sick. No more paranoia, no more isolation, no more planning your life around illness—just two products once daily and trust in your body's restored defenses.

7. Saves You $1,600+ Per Cold Season (Really)
The real cost of getting sick isn't just your immune supplement budget. Let's do the actual math:
Current spending:
• Vitamin C, zinc, elderberry, etc.: $150-250/month during cold season (4 months = $600-1,000)
• Doctor visits when you get sick anyway: $150-200 per visit × 3-4 illnesses = $450-800
• Over-the-counter medications: $25-40 per illness × 4 = $100-160
• Lost wages from sick days: $200-400 per day × 4-6 days = $800-2,400
Total annual cost of "managing" illness: $1,950-4,360
Now imagine cutting that by 50-75% by actually building real immunity. With Immune Fortress at $61-89/month (subscription), you're saving hundreds on ineffective supplements while dramatically reducing doctor visits, medications, and lost income.
The savings compound: fewer missed workdays, fewer doctor visits, no more expensive emergency immune packets, and finally—finally—a winter where you're not sick constantly.
"After 4 rounds of seemingly necessary antibiotics (surgeries, infections), my husband started experiencing obvious gut issues... Figured that was our best shot at a quality product. My husband has been on Biome Protect about 5 weeks now and his gut issues have turned around." – C.U., verified buyer

8. Unexpected Benefits That Transform Your Whole Family
You start taking Immune Fortress to stop getting sick. But then something else happens.
Your bloating disappears. Bowel movements become regular and comfortable. Energy returns that you forgot you had. Your hair stylist notices significant new growth. Skin clears and glows. Brain fog lifts. Sleep improves.
You realize that rebuilding the gut-immune axis doesn't just support immunity—it transforms your entire well-being. That's because 70% of your immune system lives in your gut, and your gut affects everything: nutrient absorption, hormone balance, neurotransmitter production, energy levels. Fix the foundation, and everything built on it improves.

9. Third-Party Tested with COAs Posted Online (Unlike 99% of Supplements)
Most supplement companies won't show you their test results. They hide behind "proprietary blends" and vague promises. You're supposed to trust them blindly.
Adapt Naturals does the opposite. Every batch of both Biome Protect and Bio-Avail Colostrum+ undergoes rigorous third-party testing for purity and potency. Then—and this is almost unheard of in the supplement industry—the results are posted publicly online.
You can see exact ingredient amounts, purity tests, and contamination screenings. No hidden fillers, no underdosed ingredients, no untested combinations. Just transparent proof that you're getting therapeutic doses of what actually works. NSF-certified facilities, no proprietary blends, clinically-effective doses—transparency that lets you make informed decisions about what you're putting in your body.
"There are so many probiotics out there, but how do you know what is really inside of them? I am so glad that Adapt Naturals created Biome Protect—I trust this company because of their 3rd party testing and the fact that they openly share their Certificates of Analysis (COAs) on their website." –Kim DelMonico, verified buyer

10. 90-Day Transformation Guarantee (3X Longer Than Others)
Most supplement companies offer 30-day guarantees because they know their products don't work—and 30 days isn't long enough to prove it.
We offer 90 days because rebuilding the gut-immune axis takes time. Your gut barrier didn't break overnight. Your microbiome didn't become imbalanced in a week. Real immunity restoration happens over weeks and months, not days.
Based on Chris Kresser's clinical experience with thousands of patients, this protocol works for the majority when given adequate time. Some people notice they're staying healthy within the first month. Others need 6-8 weeks for their gut-immune axis to fully restore. That's why we insisted on a 90-day guarantee—enough time for even stubborn cases to see real results.
"After 4 rounds of seemingly necessary antibiotics (surgeries, infections), my husband started experiencing obvious gut issues... My husband has been on Biome Protect about 5 weeks now and his gut issues have turned around." –C.U., verified buyer
💡 Chris's Experience: "In my practice, even the most stubborn cases show improvement within 90 days if they're going to respond. Some people feel the difference in weeks—others need the full three months for their gut-immune axis to rebuild. This isn't marketing—it's clinical experience. That's why we give you the time you need."
STOP MANAGING SYMPTOMS. START BUILDING REAL IMMUNITY.
