What NAD+ and NMN Injections Can Treat

What it Treats

Both NAD+ and NMN injections are used to address a variety of health concerns. Below are the common conditions and symptoms each treatment is known to support.
NAD+ Injections - What it Treats
  • Supports cellular energy production
  • Improves symptoms of chronic fatigue
  • Helps repair damaged DNA
  • Enhances cognitive function and focus
  • Reduces signs of aging, such as wrinkles and skin elasticity
NMN Injections - What it Treats
  • Boosts NAD+ levels for overall vitality
  • Supports metabolism and weight management
  • Improves cognitive function and mental clarity
  • May help combat age-related muscle loss

How it Works

Both NAD+ and NMN injections are designed to support cellular health by boosting NAD+ levels in the body. While they share a similar goal, the way they work is slightly different.
NAD+ Injections - How it Works
NAD+ Injections directly provide the body with NAD+ (Nicotinamide Adenine Dinucleotide), a crucial molecule that helps power energy production within cells. By replenishing NAD+ levels, these injections support better cellular function, improve energy levels, and aid in repairing damaged DNA, which can help address symptoms of aging, fatigue, and cognitive decline.
NMN Injections - How it Works
NMN Injections work by increasing the body's natural production of NAD+. When injected, NMN (Nicotinamide Mononucleotide) is converted into NAD+ within cells. This process supports a variety of vital functions, including enhancing metabolism, boosting energy, and promoting healthier aging by improving cellular repair and supporting brain and heart health.
