Unlocking Longevity: Peptides, Bio-Regulators, and Lifestyle Strategies for Optimal Health

At the 2025 Ultimate Wellness™ Conference, holistic nutritionist and longevity educator Nathalie Niddam—widely known for her expertise in bioregulators—delivered her groundbreaking keynote, “Longevity and Healthspan with Bioregulators and Beyond.”

Many attendees already knew her from the Longevity Podcast with Nathalie Niddam, where she breaks down the science and practice of living longer, healthier lives.

With her signature clarity and approachable style, Nathalie captivated the audience, sharing a forward-thinking framework that blends health technology, ancestral principles, peptides, and bioregulators to support wellness across the lifespan.

Drawing on years of clinical experience and research, she outlined how lifestyle, advanced testing, and targeted interventions can help preserve muscle mass, balance hormones, and enhance cognitive and metabolic function.

She unpacked complex topics—from peptide therapies to NAD optimization—translating cutting-edge science into practical strategies for both men and women at any stage of life. Throughout her keynote, Nathalie emphasized the power of integrating lifestyle, emerging technologies, and bioregulators to slow aging, elevate vitality, and empower individuals to take charge of their long-term health.

With authority and inspiration, she reminded the audience that longevity is more than cellular metrics—it’s also about emotional well-being, quality of life, and meaningful connection.

Metabolic Health and Diet

Metabolic flexibility—the body’s ability to efficiently switch between fuel sources—is key to maintaining a healthy weight, muscle mass, and long-term vitality. Chronic cardio, often overused in weight loss programs, can erode muscle over time, reducing resting calorie burn and metabolic efficiency.

Instead, strength training and resistance exercises should be prioritized to preserve and build muscle. A low-glycemic diet—one that avoids blood sugar spikes and crashes—supports stable energy, healthy insulin response, and overall metabolic resilience. Nathalie highlighted the utility of continuous glucose monitors for personalized insights into how individual bodies respond to different foods.

GLP-1 Peptides: Tools, Not Magic

Semaglutide (single agonist), tirzepatide (dual agonist), and reatrutide (triple agonist) have transformed weight management strategies. They help regulate appetite and glucose, but their effectiveness depends on personalized dosing and consistent lifestyle changes. Peptides cannot replace strength training, nutrient-dense diets, and disciplined eating habits. Muscle preservation and fat loss are optimized only when these compounds are used alongside adequate protein intake, hydration, and nutrient-dense vegetables.

Building Muscle and Supporting Recovery

Muscle is not just aesthetic—it is metabolically active tissue critical for calorie burn, joint support, immune function, and brain health. Muscle loss accelerates aging, increasing frailty and fall risk, particularly in women who historically may not have prioritized resistance training.

Peptides for Musculoskeletal Health

• BPC-157 and Thymosin Beta-4: Promote recovery from musculoskeletal injuries and enhance post-workout recovery.

• CJC-1295: Stimulates natural growth hormone production, aiding muscle gain, fat loss, and improved sleep. Caution is advised as some users may develop mild immune reactions.

Bio-Regulators for Muscle and Joints

• Cardilax: Supports collagen and elastin production, crucial for joint, skin, heart, and vascular health.

• Goratics: Focused on muscle health and recovery.

Supplements for Muscle Synthesis

• Creatine monohydrate: Research-backed for muscle strength and recovery.

• Essential amino acids and branched-chain amino acids: Support protein synthesis, particularly beneficial for those using GLP-1 peptides.

• Fertilized egg yolk products: Shown in studies to triple muscle protein synthesis.

Sleep: The Most Active State of the Day

Sleep is a cornerstone of wellness. Poor sleep disrupts hormone balance, metabolism, cognition, immune function, and muscle/bone health. Short sleep duration increases risks for obesity, diabetes, cardiovascular disease, stroke, and mental health challenges.

Optimizing Sleep Naturally

• Keep your bedroom cold and dark; consider grounding sheets or sleep masks.

• Track sleep with wearables for insights (if tracking does not induce stress).

• Consider specialized sleep technologies like the Eight Sleep mattress pad for temperature regulation and sleep stage tracking.

• Use acupressure mats or nerve stimulation devices to calm the nervous system.

Peptides and Bio-Regulators for Sleep

• Epitalon/Pineal Gland Bio-Regulator: Supports melatonin production, circadian rhythm normalization, and telomere maintenance.

• CJC-1295 or DSIP: Can be used selectively, though effectiveness varies per individual.

Hormone Health and Bio-Regulators

Hormones are master regulators of energy, mood, cognition, and body composition. With age, sex hormone levels decline, affecting men and women differently.

Female Hormone Support

• HRT (Hormone Replacement Therapy): Can mitigate perimenopause and menopause symptoms, improve sleep, cognition, and body composition—but requires knowledgeable medical supervision to balance estrogen and progesterone levels.

• Bio-regulators targeting the pineal, adrenal, and thyroid glands can indirectly support hormone balance.

Male Hormone Support

• Testosterone levels are declining in younger men, largely due to lifestyle factors: poor sleep, chronic stress, and visceral fat accumulation.

• Lifestyle strategies (strength training, nutrition, sleep) remain foundational.

• Bio-regulators for testosterone and prostate health can provide adjunctive support, but hormonal testing is essential before supplementation.

Advanced Testing for Longevity

Testing is critical to understand and monitor health, identify risks early, and track the effectiveness of interventions.

Key Tests to Consider

• Hormones: Blood work first, followed by Dutch tests if necessary. Assess T3, T4, and RT for thyroid function—not just TSH.

• Bone Health: DEXA scans for density; Eolite/REM scan for bone quality, assessing collagen, elastin, and resilience.

• Body Composition: InBody scans, creatine kinase for muscle breakdown.

• Inflammation: High-sensitivity CRP and other markers.

• Sleep: At-home sleep tests for HRV, stages, and latency.

• Biological Age: Tests like Theome Aristotle provide insights into metabolomics and biological aging.

• Advanced Cancer Screening: QT scans for women as a safer, more effective alternative to mammograms.

NAD and Cellular Health

NAD is essential for cellular metabolism, DNA repair, and longevity. While NAD IVs can provide acute benefits, chronic high-dose use may have unintended consequences, including cancer risk.

Nathalie recommends:

• NAD precursors combined with CD38 downregulators to support cellular NAD levels safely.

• Strategic, supported NAD IV therapy rather than frequent chronic administration.

• Supplements like Qualia NAD, Health Jevity NAD stack, and Nicola Conland formulations are preferred for at-home, long-term maintenance.

Practical Takeaways for Longevity

Muscle is life: Strength training is essential.

Sleep is anabolic: Build a restorative sleep routine before turning to supplements.

Diet matters: Low-glycemic, nutrient-dense, protein-forward eating supports health.

Hormones guide: Testing, balancing, and bio-regulator support help offset age-related shifts.

Peptides and bioregulators: When used wisely, they boost recovery, muscle, and cellular health—but never replace lifestyle.

Advanced testing: Track hormones, sleep, bone health, and biological age to personalize strategies.

Community and joy: Connection, gratitude, and happiness strengthen health.

Nathalie Niddam’s mission was clear: to empower attendees with the knowledge, tools, and confidence to extend their healthspan and live vibrantly at any age. By combining evidence-based lifestyle strategies with targeted peptides, bio-regulators, and advanced testing, we can actively influence our aging trajectory, optimize vitality, and support long-term health. The key is a holistic approach that integrates these tools while honoring the interconnectedness of the body’s systems.
