Functional medicine takes a root-cause approach to weight loss and wellness — focusing on cellular health, inflammation control, and metabolic repair.

Today’s most exciting tools in this space are bioactive peptides and NAD⁺, which work together to enhance mitochondrial function, optimize hormones, and accelerate tissue healing.

Instead of suppressing symptoms, these therapies help restore the body’s natural balance, leading to sustainable fat loss, improved energy, and long-term vitality.

1. Tirzepatide: Dual Hormone Support for Metabolic Reset

Tirzepatide is a dual GIP and GLP-1 receptor agonist that mimics two powerful gut hormones responsible for regulating insulin, appetite, and fat metabolism.

Benefits:

Regulates blood sugar and reduces insulin resistance
Promotes satiety and reduces cravings
Improves energy utilization and metabolic flexibility

Functional medicine insight:When paired with nutrient-dense diets, gut support, and NAD⁺ replenishment, Tirzepatide helps reset the metabolism rather than simply suppressing appetite.

2. BPC-157 and TB-500: The Dynamic Duo for Repair and Recovery

These two healing peptides work synergistically to accelerate tissue repair and reduce inflammation.

BPC-157 (Body Protection Compound) helps heal the gut lining, reduces inflammation, and supports muscle and ligament repair.TB-500 (Thymosin Beta-4) promotes angiogenesis — the formation of new blood vessels — which improves nutrient delivery and recovery.

Benefits:

Repairs leaky gut and supports digestive health
Speeds up healing of muscles, tendons, and ligaments
Reduces systemic inflammation and enhances recovery

Functional medicine insight:For those dealing with chronic inflammation, autoimmune flares, or slow recovery that stall weight loss, these peptides help the body repair itself from within.

3. GHK-Cu: The Cellular Rejuvenation Peptide

GHK-Cu (Copper Peptide) is a naturally occurring compound known for its regenerative and anti-aging properties. It stimulates collagen production, supports wound healing, and combats oxidative stress.

Benefits:

Improves skin elasticity and tissue repair
Acts as a potent antioxidant
Enhances vascular and mitochondrial function

Functional medicine insight:While GHK-Cu is often known for cosmetic use, its cellular benefits go far beyond skin — promoting healthy aging, better circulation, and more efficient metabolism.

4. KPV: The Inflammation-Calming Peptide

KPV is a short peptide derived from alpha-MSH, recognized for its ability to calm inflammation and balance immune activity.

Benefits:

Reduces systemic and gut inflammation
Supports immune balance
Strengthens the intestinal barrier

Functional medicine insight:Chronic inflammation can block hormone balance and fat loss. KPV helps reset the inflammatory response and supports gut health — two key factors in metabolic health.

5. NAD⁺: The Cellular Energy Catalyst

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in every cell, responsible for energy production, DNA repair, and healthy aging. Levels decline naturally with age, leading to fatigue, slower metabolism, and decreased recovery.

Benefits:

Boosts mitochondrial energy and fat oxidation
Improves mental clarity and focus
Enhances cellular repair and longevity
Activates sirtuins — the body’s “longevity genes”

Functional medicine insight:When combined with peptides like Tirzepatide or GHK-Cu, NAD⁺ amplifies their effects — helping restore energy, metabolism, and cellular repair for more sustainable health results.

How Functional Medicine Combines Peptides and NAD⁺

Functional medicine providers design personalized peptide protocols that target multiple systems simultaneously.

Common combinations include:

Tirzepatide + NAD⁺ for metabolic optimization and fat loss
BPC-157 + KPV for gut healing and inflammation control
TB-500 + GHK-Cu for tissue repair and recovery
NAD⁺ + GHK-Cu for energy, anti-aging, and cellular regeneration

Each plan is customized based on lab testing, hormone levels, gut health, and individual goals — creating a truly personalized healing strategy.

The Takeaway: Precision Medicine for a Healthier Future

The combination of peptides and NAD⁺ represents the future of functional medicine — a shift from symptom suppression to cellular optimization.

By targeting inflammation, mitochondrial function, hormonal balance, and tissue repair, these therapies create a foundation for lasting weight loss, improved performance, and healthy aging.

When integrated with lifestyle pillars like nutrition, sleep, movement, and stress management, peptide therapy and NAD⁺ can help you rebuild your health from the inside out.
