CellGuard-NR™
CellGuard-NR™ by Designs for Health is a practitioner-grade cellular health and healthy aging formula designed to support the body’s natural cellular repair processes, antioxidant defenses, and energy metabolism.* It combines clinically relevant amounts of nicotinamide riboside (NR), resveratrol, and pterostilbene—three well-researched compounds that work synergistically to support cellular resilience and longevity pathways.
At Yarrow Holistic Center, CellGuard-NR™ is often incorporated into personalized care plans for patients seeking proactive support for cellular and metabolic health, healthy aging, and oxidative stress balance. It is frequently recommended for patients receiving guidance through telehealth consultations, where long-term wellness and preventative strategies can be monitored and refined remotely.
Advanced Support for Cellular Energy & Repair
CellGuard-NR™ is formulated to support key biological pathways involved in cellular energy production, DNA repair, and stress response.* Central to this process is NAD+ (nicotinamide adenine dinucleotide), a molecule found in every living cell.
NAD+ plays a role in more than 500 enzymatic reactions in the body, including:
- Cellular energy production*
- Gene expression and cellular signaling*
- DNA repair and cellular maintenance*
- Adaptation to metabolic and oxidative stress*
Levels of NAD+ naturally decline with age, making targeted nutritional support an important consideration in integrative care.
Key Ingredients & Their Roles
CellGuard-NR™ delivers three complementary compounds in bioavailable, clinically studied forms:
- Nicotinamide Riboside (Niagen®) – A form of vitamin B3 that serves as a direct precursor to NAD+, supporting cellular energy and repair mechanisms*
- Trans-Resveratrol (Veri-te™) – A polyphenol that supports antioxidant defenses and a healthy response to oxidative stress and inflammation*
- Trans-Pterostilbene – A highly bioavailable compound structurally related to resveratrol that supports cellular protection and healthy inflammatory balance*
Together, these nutrients help promote a healthy cell cycle, cellular repair, and overall cellular function associated with healthy aging.*
Ideal for Holistic & Telehealth-Based Care
CellGuard-NR™ is commonly used within functional medicine and integrative internal medicine care plans.
Within a telehealth model, it may be combined with:
- Antioxidant and mitochondrial support strategies
- Healthy aging and longevity-focused protocols
- Metabolic and energy optimization plans
- Nutrition and lifestyle guidance tailored to long-term wellness
This makes CellGuard-NR™ a strong option for patients seeking preventative, systems-based support rather than symptom-only approaches.
Suggested Use
Take two (2) capsules once daily with a meal, or as directed by your healthcare practitioner.
Consistent daily use is recommended to support ongoing cellular processes.
