Gut Barrier & Metabolic Repair Stacks - Morning and Evening Protocol
This post does NOT constitute medical advice. It is a synthesis of lab-driven reasoning based on a Foundation Zoomer and related gut findings (elevated Anti-LPS, zonulin signals, Gut Score 71, Liver sub-score 65, HOMA-IR 2.7). Work with a knowledgeable clinician before making changes.
TL;DR
Morning – Empty Stomach
L-Glutamine 5 g + Zinc Carnosine 75 mg + Taurine 1 g + NAC 1 g + Glycine 5 g + Apolactoferrin 250 mg + Florastor + Sunfiber 6 g + Bifidobacterium lactis + Boron 3–6 mg
Morning – With Food
Fish Oil (high EPA/DHA) + Siliphos 300 mg + TriButyrin 300 mg + Quercetin Phytosome 250–500 mg (+ optional UC-II 40 mg and/or bioavailable curcumin)
Evening – Before Bed
Glycine 10 g + Magnesium L-Threonate + Taurine 1 g + NAC 1 g + Fish Oil + Apigenin 50 mg + L-Theanine 200 mg + Mushroom complex (optional) + TA-65 (optional)
Core goal: Repair intestinal barrier, lower endotoxin load, support liver, improve insulin sensitivity, and create a cleaner cellular environment via periodic 50–65 hour fasts.
Introduction
The protocol below was built around the most actionable findings from the July 2026 Foundation Zoomer:
- Gut Score 71 (Moderate) with clear barrier stress signals (Anti-LPS, zonulin)
- Liver sub-score 65 and history of elevated GGT/ALT
- HOMA-IR 2.7 (insulin resistance)
- Secondary immune activation (immature granulocytes, basophils)
- Cardiovascular score 73
The stacks prioritize evidence-aligned tools that directly address intestinal permeability, endotoxin translocation, short-chain fatty acid support, liver membrane and antioxidant status, and systemic inflammation. Periodic 50–65 hour water fasts are used as a complementary stimulus for autophagy and mitophagy.
Morning Stack – Empty Stomach / Early
| Supplement | Dose | Primary Purpose | Why It Matters |
|---|---|---|---|
| L-Glutamine | 5 g | Enterocyte fuel & tight junction support | Primary metabolic fuel for intestinal lining cells; foundational for barrier repair |
| Zinc Carnosine | 75 mg complex | Mucosal stabilization | Directly supports tight junctions and reduces permeability; one of the strongest evidence-based barrier agents |
| Taurine | 1 g | Bile support + mild calming | Supports bile flow and liver function; pairs well with fasting and refeeds |
| NAC | 1 g | Glutathione & liver support | Boosts glutathione; helps with oxidative stress and elevated liver enzymes |
| Glycine | 5 g | Barrier + glutathione + calming | Supports collagen/barrier structures and glutathione synthesis |
| Apolactoferrin | 250 mg | LPS binding | Helps bind and reduce bacterial endotoxin load |
| Florastor (S. boulardii) | 250 mg | Barrier & pathogen resistance | Yeast probiotic with data for supporting intestinal integrity |
| Sunfiber (PHGG) + B. lactis | 6 g + 8 billion CFU | SCFA production & Bifido support | Raises butyrate and other SCFAs; feeds beneficial bacteria |
| Boron | 3–6 mg | Mild anti-inflammatory + joint support | May help with inflammation and has some osteoarthritis data |
Reasoning: These are the highest-leverage tools for the Gut Score of 71 and elevated permeability/LPS signals. They work best on an empty or near-empty stomach so they can interact directly with the intestinal lining.
Morning Stack – With Food
| Supplement | Dose | Primary Purpose | Why It Matters |
|---|---|---|---|
| Fish Oil | ~1.5–2 g combined EPA+DHA | Anti-inflammatory & lipid support | Addresses systemic inflammation and cardiovascular score; supports resolution of inflammatory signaling |
| Siliphos (Milk Thistle Phytosome) | 300 mg | Liver membrane & enzyme support | Targets the weak Liver sub-score (65) and elevated enzymes |
| TriButyrin | 300 mg | Direct butyrate delivery | Fuels colonocytes and supports barrier integrity from the colonic side |
| Quercetin Phytosome | 250–500 mg | Tight junction & mast cell support | Complements glutamine and zinc carnosine; reduces LPS-driven inflammation |
| UC-II (optional) | 40 mg | Joint / oral tolerance | Evidence-based for osteoarthritis symptoms |
| Bioavailable Curcumin (optional – Thorne Meriva preferred) | 500–1000 mg Meriva or equivalent | Anti-inflammatory | Additional joint and systemic inflammation support |
Reasoning: These ingredients absorb better with food (especially fat) and provide complementary anti-inflammatory, liver, and butyrate support without competing with the empty-stomach barrier agents.
Evening Stack
| Supplement | Dose | Primary Purpose | Why It Matters |
|---|---|---|---|
| Glycine | 10 g | Sleep quality + continued barrier support | Improves sleep architecture and supplies ongoing glycine for repair |
| Magnesium L-Threonate | ~725 mg (or as labeled) | Brain magnesium & sleep | Supports relaxation, sleep quality, and recovery |
| Taurine | 1 g | Continued liver/bile + calming | Maintains support overnight |
| NAC | 1 g | Overnight glutathione & liver support | Keeps antioxidant capacity elevated |
| Fish Oil | Split dose | Steady anti-inflammatory coverage | Maintains omega-3 levels |
| Apigenin | 50 mg | Sleep pressure & fewer awakenings | Gentle GABA modulation |
| L-Theanine | 200 mg | Reduced mental arousal | Helps with sleep onset and continuity |
| Mushroom complex (optional) | ~1 g | Immune modulation & calming | Reishi in particular supports evening wind-down |
| TA-65 (optional) | As directed | Telomerase support | Longevity-oriented; not core to the lab findings |
Reasoning: Evening dosing emphasizes recovery, sleep quality (which itself supports barrier repair and metabolic health), and continued low-level support for liver and glutathione status.
How the Stacks Map to the Labs
- Gut Score 71 / Anti-LPS / Zonulin → Glutamine, Zinc Carnosine, TriButyrin, Sunfiber, Apolactoferrin, Quercetin, Florastor
- Liver sub-score 65 → Siliphos, NAC, Taurine, Glycine
- HOMA-IR 2.7 → Omega-3s, reduced inflammatory load, periodic fasting, better sleep
- Systemic inflammation & immune activation → Fish oil, Quercetin, Apolactoferrin, lower LPS translocation
- Sleep & recovery → High-dose Glycine, Magnesium L-Threonate, Apigenin, L-Theanine, Taurine
Fasting Integration (50–65 Hours)
Three well-spaced 50–65 hour water fasts over 8–12 weeks are used to drive autophagy and mitophagy. During the fast, prioritize electrolytes, magnesium, taurine, and NAC. Pause the higher-amino-acid and caloric items (glutamine, high-dose glycine, Sunfiber, fish oil, Siliphos, etc.) until the gentle refeed.
Mitophagy (selective clearance of damaged mitochondria) is particularly relevant to gut health because intestinal epithelial cells require healthy mitochondria to maintain tight junctions and control local ROS and inflammation.
Expected Timeline
Weeks 1–4: Focus on consistency and tolerance. Barrier-support nutrients begin working.
Weeks 4–8: First and second 50–65 hour fasts. Progressive reduction in inflammatory and permeability signals expected.
Weeks 8–12: Third fast + retesting of key markers (Gut Score / permeability markers, liver enzymes, HOMA-IR).
Final Notes
This protocol is deliberately layered: daily high-leverage barrier and liver support, evening recovery and sleep optimization, and periodic deep autophagy/mitophagy stimuli. The largest expected improvements are in gut barrier markers, liver enzymes, and insulin sensitivity.
Reassess with labs at 8–12 weeks and adjust. The goal is measurable progress on the weakest scores, not indefinite high-intensity supplementation.
