The Gut Protocol
All health begins in the gut. The Gut Protocol is your complete digestive system overhaul.
The gut is your second brain. It produces 95% of your body's serotonin. It houses 70% of your immune system. It communicates directly with your brain through the vagus nerve. And for most people — especially veterans, high-stress professionals, and anyone who has ever taken antibiotics or eaten a modern Western diet — it is the single most damaged and neglected system in the body. The Gut Protocol is five targeted products working from the top of your digestive tract to the bottom — rebuilding, defending, cleansing, and optimizing every aspect of your gut health. Made fresh to order in Golden, Colorado. Veteran-owned. Built for people who understand that fixing the gut fixes almost everything.
🌿 What's In The Stack & Why It Works
1. Gut Healer Probiotic — 40 Billion Units Your gut microbiome contains over 38 trillion bacteria — and the balance of those bacteria determines your digestion, immune function, mood, metabolic rate, and even cognitive performance. Antibiotics, stress, poor diet, alcohol, and environmental toxins all damage and deplete your microbiome. SFL's Gut Healer delivers 40 billion CFU of diverse, clinically studied probiotic strains in a formula designed for maximum survival through stomach acid to the colonization site in your large intestine. This is the foundation of the entire protocol — you must repopulate before you can optimize. Take it first thing in the morning on an empty stomach.
2. Digestive Enzyme Pro Blend You can eat the cleanest diet in the world and still be malnourished if you're not breaking down and absorbing your food properly. Digestive enzyme production declines with age, stress, and gut dysbiosis — leaving undigested food particles that ferment in the gut, causing bloating, gas, and systemic inflammation. SFL's Digestive Enzyme Pro Blend provides a comprehensive spectrum of enzymes — protease for proteins, lipase for fats, amylase for carbohydrates, lactase for dairy, cellulase for plant fiber — ensuring everything you eat is actually digested, absorbed, and used. Take it with every major meal — especially high-protein or high-fat meals.
3. Ox Bile Complex: Max Absorption Bile is the emulsifying agent your liver produces to break down dietary fats and fat-soluble vitamins — A, D, E, and K. If your bile production or flow is compromised — common after gallbladder removal, with liver stress, or with poor fat digestion — you cannot absorb these critical vitamins regardless of how much you supplement. You may also experience floating stools, chronic diarrhea after fatty meals, and deficiencies in fat-soluble nutrients despite eating well. SFL's Ox Bile Complex, standardized to 40% cholic acid, provides targeted bile support alongside DigeZyme® and artichoke extract to restore proper fat digestion and dramatically improve fat-soluble nutrient absorption. Take it with your fattiest meal of the day.
4. Wild Forest Gut Defense A healthy gut isn't just about adding beneficial bacteria — it's about defending against the harmful organisms that compete with them. Wild Forest Gut Defense delivers a powerful botanical antimicrobial blend — compounds from wild forest plants that have been used for centuries to support gut immunity, crowd out pathogenic bacteria, yeast overgrowth, and parasites, while supporting the integrity of the gut lining itself. This is the defensive layer of the protocol. While your probiotics rebuild, Wild Forest Gut Defense creates an environment where beneficial bacteria can thrive and harmful organisms cannot. Take with food.
5. Gut Health Max Detox: Black Walnut, Acai & Elm Bark Black walnut hull has been used in traditional medicine for centuries as one of nature's most powerful anti-parasitic and gut-cleansing botanicals. Combined with acai — rich in anthocyanins and antioxidants that support gut lining health — and slippery elm bark, which coats and soothes the intestinal wall, this formula completes the gut protocol by addressing gut lining integrity and elimination. A gut that can't eliminate efficiently recirculates toxins. This formula ensures your body clears waste effectively and your gut lining is protected and healed. Take at night before bed.

👤 Who Is The Gut Protocol For?
- Anyone with chronic bloating, gas, or IBS-type symptoms — this is your starting point
- People who have taken antibiotics in the past 2 years — antibiotics devastate the microbiome; this protocol rebuilds it properly
- Veterans — military service is associated with high rates of gut dysbiosis from stress, inconsistent nutrition, and antibiotic use
- Anyone who has had their gallbladder removed — ox bile is especially critical for this population
- People with food sensitivities — often a sign of compromised gut lining and enzyme deficiency
- Those with autoimmune conditions — 70% of the immune system is in the gut; healing the gut often dramatically improves autoimmune symptoms
- Anyone who has done a Western diet for years — processed food, sugar, and alcohol are catastrophic to the microbiome; this protocol resets the damage
- People with poor mental health — gut-brain connection means fixing the gut often improves anxiety, depression, and cognitive function as a direct downstream effect
📅 What To Expect Week By Week
Week 1: Bloating and gas may temporarily increase as die-off occurs (Herxheimer reaction) — this is normal and passes. By day 5–7 most users notice significantly reduced bloating and more regular elimination.
Week 2–3: Digestion noticeably smoother. Less discomfort after meals. Energy improving as nutrient absorption improves. Mood often begins to improve as gut-brain axis heals.
Week 4–6: Microbiome diversity meaningfully improved. Food sensitivities often reduce. Skin often clears (gut-skin axis). Many users report improved mental clarity and mood stability as serotonin production normalizes.
Week 8–12: Full gut healing and microbiome rebuilding. This is where dramatic systemic improvements occur — improved immunity, better metabolic function, clearer skin, more stable mood, and significantly better overall health.
