RetzlerRx® Synergy-NR | NIAGEN® Nicotinamide Riboside for NAD⁺ & Cellular Energy

RetzlerRx® Synergy-NR is a cellular health supplement formulated to support NAD⁺ production, mitochondrial function, and cellular energy metabolism. This practitioner-grade formula features nicotinamide riboside, a form of vitamin B3 that serves as a precursor to NAD⁺—a critical coenzyme involved in cellular energy production and metabolic resilience.

NAD⁺ levels naturally decline with age, which may influence mitochondrial efficiency, metabolic function, and cellular repair pathways. By helping support healthy NAD⁺ levels, Synergy-NR is designed to promote cellular vitality, healthy aging, and sustained energy metabolism as part of a broader lifestyle and longevity strategy.

Why NAD⁺ Matters for Cellular Health

NAD⁺, or nicotinamide adenine dinucleotide, is a key coenzyme involved in hundreds of metabolic reactions throughout the body. It plays an essential role in mitochondrial energy production, DNA repair pathways, and cellular signaling. Maintaining healthy NAD⁺ levels supports normal cellular function and metabolic balance as we age.
