Five Pillars of Health for Longevity: A Guide for Foundational Care
The Five Pillars framework organizes longevity care into foundational lifestyle, gut and liver health, hormonal optimization, regenerative interventions, and continuous testing with iteration. This guide summarizes the evidence, maps practical protocols, and shows where peptide and hormone therapies can complement pillar work.
Overview
Longevity care is most durable when it sits on a structured base. The Five Pillars model used by Regen Therapy groups interventions into domains that are simple to understand and practical to implement at the bedside. Pillar 1 covers the daily levers that shift disease risk curves. Pillar 2 addresses the gut and liver axis that determines inflammation and detoxification capacity. Pillar 3 calibrates the endocrine systems that control energy, growth, and repair. Pillar 4 applies regenerative tools for targeted cellular and tissue support. Pillar 5 closes the loop with measurement and iteration so protocols improve over time.
This article summarizes each pillar for a mixed audience of clinicians and high information readers. For providers, it offers scaffolding that supports protocol design. For longevity enthusiasts, it explains how to build a personal program that is comprehensive, efficient, and data informed. Where appropriate, we show how specific peptide and hormone therapies can complement pillar work, while reinforcing that foundations come first.
Pillar 1. Foundational Lifestyle: Nutrition, Exercise, Sleep, Stress
Lifestyle is the largest modifiable driver of healthspan. Programs that consistently improve nutrition quality, physical activity, sleep, and stress resilience can add disease free years and compress morbidity. Everything else in longevity builds on this base.
Nutrition
Focus on whole foods, adequate protein, fiber density, and glycemic control.
Protein targets: Most adults aiming to preserve or regain lean mass do well with 1.2 to 2.0 grams per kilogram per day, adjusted for kidney status and training age. Protein adequacy supports mitochondrial function, immune competency, and bone remodeling.
Fiber and phytonutrients: Aim for 25 to 40 grams of fiber daily through legumes, vegetables, whole grains, nuts, and seeds. Diverse fiber supports a resilient microbiome and reduces systemic inflammation.
Glycemic strategy: Prefer low glycemic starches and time higher glycemic loads around exercise. Continuous glucose monitors can be useful short term to tighten habit feedback.
Exercise
Exercise is the closest thing to a generalized longevity drug.
Resistance training: Two to four sessions weekly to counter sarcopenia. Prioritize compound movements, progressive overload, and sufficient recovery.
Aerobic training: At least 150 minutes weekly of moderate to vigorous work. Mix zone 2 for mitochondrial adaptations with periodic intervals for VO2 peak capacity.
Movement hygiene: Break up long sitting blocks. Add mobility and gait quality work to reduce fall risk.
Sleep
Seven to nine hours per night for most adults. Focus on consistency, light control, temperature, and caffeine timing. Treat sleep apnea and circadian disorders. Improvements in slow wave sleep correlate with better glycemic control, appetite regulation, and next day executive function.
Stress Management
Chronic sympathetic load accelerates biological aging. Train down baseline arousal with breath work, mindfulness, and exposure to green space. Support social connection. Pair techniques with objective measures like heart rate variability so patients see progress.
Where peptides and hormones fit
MOTS-c can be considered as a training adjunct and recovery support in select adults. It signals exercise like pathways in skeletal muscle and may help with energy management during higher training blocks.
CJC-1295 with or without Ipamorelin is used by some practitioners to support deeper sleep architecture and nighttime repair by nudging physiologic growth hormone release. It is adjunctive to sleep hygiene and not a replacement.
GLP-1 receptor agonists such as semaglutide can support energy balance for patients with obesity or insulin resistance when lifestyle alone stalls. Pair with resistance training and protein to protect lean mass.
Pillar 2. Gut and Liver Health: The Core of Systemic Wellness
The gut and liver together decide what the body absorbs, how the immune system reacts to it, and how efficiently toxins are cleared. A resilient gut barrier and an unburdened liver lower chronic inflammation and stabilize metabolic signaling.
Gut integrity and microbiome
Barriers and balance: Protect tight junctions and mucus layer with fiber rich food, fermented foods as tolerated, and targeted probiotics when indicated. Reduce alcohol and ultra processed foods that increase permeability.
GI symptoms and mapping: Address reflux, IBS patterns, and suspected small intestinal bacterial overgrowth with stepwise evaluation. Consider stool analysis for patients with persistent symptoms.
Liver health and detoxification
Hepatic load: Limit alcohol, acetaminophen overuse, and environmental exposures. Maintain healthy weight to prevent fatty infiltration. Use diet patterns rich in crucifers, alliums, and citrus pectin to support phase I and II detox enzymes.
Lab watch list: ALT, AST, GGT, fasting triglycerides, fasting glucose and insulin, ferritin, and markers of cholestasis as clinically indicated.
Where peptides fit
BPC-157 is frequently explored for gut mucosal support and post injury healing. In practice, it is paired with elimination diets, fiber repletion, and stress reduction that reduce gut hypervigilance.
KPV is studied for epithelial calming and may be considered in inflammatory gut contexts with clinician oversight.
GLP-1s indirectly benefit the gut and liver through weight loss, improved insulin sensitivity, and lower hepatic fat in metabolic syndrome. These are metabolic tools, not first line gut repair agents.
Pillar 3. Hormonal Optimization: Aligning the Body’s Command Centers
Endocrine systems govern energy production, tissue maintenance, reproduction, and neurocognition. Correcting true deficiencies and smoothing dysregulation can restore function and improve quality of life.
Sex hormones
Men: Evaluate total and free testosterone, SHBG, estradiol, hematocrit, and LH. True hypogonadism merits a discussion of replacement with shared decision making and routine monitoring.
Women: Perimenopause and menopause require personalized strategies using lifestyle, non hormonal options, and bioidentical hormone therapy when appropriate. Routes and doses matter for benefit risk balance.
Thyroid axis
Screen with TSH and reflex free T4. Consider free T3 and thyroid antibodies in symptomatic patients. Treat overt hypothyroidism. Subclinical cases require clinical judgment. Optimize iodine, selenium, iron, and vitamin D status.
Adrenal and stress hormones
Support circadian cortisol through sleep, light timing, exercise scheduling, and stress training. Consider DHEA support in low DHEA-S adults with appropriate contraindication screening.
Metabolic hormones
Target fasting glucose, fasting insulin, and A1c. Strength training increases insulin sensitivity. GLP-1s reduce caloric intake and improve glycemia for obesity and type 2 diabetes. Pair with protein and creatine to defend lean mass.
Where peptides fit
CJC-1295 and Ipamorelin as secretagogues are sometimes used to support recovery and sleep in low GH symptom clusters with normal IGF-1. Use with caution and monitoring.
Tesamorelin is a GHRH analog with data for visceral fat reduction in specific populations. It is a specialty option under physician care rather than a general longevity tool.
Pillar 4. Regen Therapy: Advanced Regenerative Interventions
Once the foundations are set, targeted regenerative tools can support tissue repair, cellular renewal, and cognitive resilience. These are adjuncts, not substitutes, and belong inside a monitored plan.
Peptide examples
Epitalon is explored for its effects on telomerase activity and sleep rhythm normalization protocols. Evidence remains early, but it illustrates the category of cellular signaling aimed at healthy aging biology.
GHK-Cu supports wound healing and skin remodeling. Topical or injectable strategies can complement collagen support and red light therapy for dermal health.
BPC-157 and TB-500 are often paired in musculoskeletal protocols to speed tendon and soft tissue recovery after injury, alongside physical therapy and graded loading.
Nootropic support
Selank and Semax appear in cognitive resilience programs in some regions. They are not FDA approved in the United States. If used, position them as experimental cognitive hygiene adjuncts rather than core therapies.
Hormone and metabolic supports
GLP-1s for weight management and fatty liver improvement in appropriate patients.
Thyroid and sex hormone optimization once diagnostic criteria are met and lifestyle work is underway.
Guardrails
Use the simplest intervention that works. Escalate only when foundations are in place. Cycle and re-evaluate to avoid protocol creep.
Pillar 5. Testing, Monitoring, and Iteration
Longevity is a moving target. Measurement prevents guesswork, catches risks early, and proves what is working for a given patient.
Baseline and follow up labs
Core set: CBC, CMP, fasting lipids and apolipoproteins, hs-CRP, fasting glucose and insulin, A1c, TSH with reflex to free T4, vitamin D, B12 and folate, ferritin and iron saturation. Expand based on findings.
Endocrine detail: Free testosterone and estradiol, SHBG, DHEA-S, IGF-1 when indicated. Thyroid antibodies for autoimmune suspicion.
Liver and kidney: ALT, AST, GGT, ALP, bilirubin, eGFR, urine ACR as needed.
Functional and digital markers
Body composition via DXA or BIA to track lean mass while using GLP-1s or caloric deficits.
Fitness testing benchmarks. Resting heart rate and HRV via wearables for stress adaptation.
Optional biological age measurements to provide directional insight, interpreted cautiously.
Iteration cadence
Recheck key biomarkers every 3 to 6 months during changes, then 6 to 12 months when stable. Adjust based on data and symptoms. Remove what is not helping. Keep what moves the needle.
Benefits and Outcomes
Disease risk reduction: Lifestyle and metabolic improvements lower incidence of cardiovascular disease, type 2 diabetes, NAFLD, osteoporosis, and some cancers.
Function and quality of life: Preserved muscle and bone, better sleep, stable mood, improved executive function, and higher energy.
Healthspan compression: The goal is fewer years with disability by pushing frailty and multimorbidity later in life.
Program efficiency: Structured pillars reduce overwhelm, align teams, and create repeatable care pathways.
Risks, Side Effects, and Professional Considerations
Lifestyle risk: Rapid changes without support can backfire. Phase changes with coaching and track adherence.
Supplements and interactions: Quality control and drug nutrient interactions require pharmacist aware planning.
Peptides and hormones: Use inside clinician supervised protocols with informed consent. Monitor labs. Watch for immunogenicity concerns with certain research peptides. Respect regulatory status.
GLP-1s: GI effects are common. Titrate slowly. Pair with progressive resistance training and sufficient protein to protect lean mass. DXA monitoring is recommended during significant weight loss.
Equity and access: Be mindful of cost and complexity. Many gains come from low cost changes done consistently.
Related Therapies and Alternatives
Behavioral programs: Cognitive behavioral therapy for insomnia, stress skills training, and motivational interviewing to sustain pillar habits.
Nutrition formats: Mediterranean, DASH, high protein plant forward, or targeted low carb approaches chosen to fit the patient.
Recovery modalities: Heat and cold exposure, massage, myofascial work, and breath training can accelerate return to baseline after stressors.
Conservative musculoskeletal care: Physical therapy, graded exposure, and load management before injections.
