NAD+ vs NR: What They Treat

What it Treats

When choosing between NAD+ vs NR, itโ€™s important to understand the conditions and symptoms that each treatment is commonly used to address. Hereโ€™s a breakdown of what each therapy can help with.
NAD+ - What it Treats
  • Supports Cellular Energy Production: Boosts energy at the cellular level.
  • Manages Fatigue: Helps reduce chronic tiredness and exhaustion.
  • Improves Mitochondrial Function: Enhances the efficiency of the cellโ€™s powerhouses.
  • Supports Healthy Aging: Contributes to overall vitality and anti-aging benefits.
  • Enhances Cognitive Clarity: Aids in maintaining focus and brain health.
NR - What it Treats
  • Boosts NAD+ Levels: Promotes optimal energy metabolism.
  • Supports Metabolic Health: Assists in weight management and metabolic balance.
  • Improves Cellular Repair: Enhances natural cell regeneration processes.
  • Manages Age-Related Decline: Helps alleviate symptoms of aging.
  • Enhances Mitochondrial Health: Supports the function and integrity of mitochondria.

How it Works

Both NAD+ and NR share the goal of supporting cellular energy production and promoting overall cell health, which is vital for combating age-related decline and fatigue.
NAD+ - How it Works
NAD+ is a naturally occurring coenzyme that plays a critical role in converting food into energy within cells. By directly replenishing NAD+ levels, this therapy helps enhance mitochondrial function and supports processes like DNA repair, which can lead to improved energy, cognitive clarity, and overall well-being.
NR - How it Works
Nicotinamide riboside (NR) is a form of vitamin B3 that acts as a precursor to NAD+. Once ingested, NR is converted into NAD+, indirectly boosting cellular energy production. This mechanism supports metabolic processes, aids in cellular repair, and helps address symptoms of aging, making it a valuable tool for maintaining vitality.

Main Benefits

Below are the main benefits of these medications, detailing the specific conditions, symptoms, and health concerns that NAD+ and NR therapies effectively address.
NAD+ - Main Benefits
  • Reduces chronic fatigue by boosting cellular energy production.
  • Enhances cognitive function and mental clarity.
  • Alleviates age-related decline through improved DNA repair and mitochondrial support.
  • Improves metabolic efficiency for sustained energy levels.
  • Supports cardiovascular and liver health by optimizing cellular processes.
NR - Main Benefits
  • Increases NAD+ levels to drive efficient cellular energy production.
  • Boosts mitochondrial function for enhanced overall cell performance.
  • Alleviates symptoms of aging by promoting natural cellular repair.
  • Supports metabolic balance and aids in healthy weight management.
  • Improves long-term vitality and cardiovascular health through sustained energy support.

NAD+ vs NR: Key Administration Details

Dosing Requirements
