What is NAD+? A Beginner’s Guide to the Molecule Behind Energy and Vitality

What is NAD+ and Why Does It Matter?

NAD+ is a naturally occurring molecule found in every living cell. Scientists call it a “coenzyme” that acts like a helper molecule that allows enzymes to function, especially those involved in energy production and cell repair.

Think of NAD+ as a key component in the system that keeps your cells energized and resilient. Without it, your body would have a much harder time performing basic tasks like turning food into fuel or recovering from stress.

But here’s the catch: NAD+ levels decline over time. Starting in your 30s, your ability to maintain healthy NAD+ levels begins to drop, making you feel a bit less like yourself.

‍

How NAD+ Works in the Body

NAD+ plays a critical role in several core biological processes:

• Converting carbohydrates, fats, and proteins into usable cellular energy (ATP)
  
• Supporting natural repair mechanisms for DNA and cellular damage
  
• Regulating metabolism and mitochondrial health
  
• Assisting with internal circadian rhythm and stress response
  
  

It acts like a biological connector, helping enzymes “switch on” the processes that keep you functioning at your best. But with age, stress, or inflammation, NAD+ production slows down.

That’s why NAD+ has become a focus in wellness and longevity conversations.

Signs NAD+ Levels May Be Declining

Although you can't measure NAD+ levels at home, some signs may suggest your body could benefit from NAD+ support:

• Persistent fatigue even after a full night’s rest
  
• Increased brain fog or difficulty focusing
  
• Slower post-workout recovery
  
• Feeling “off” despite healthy habits
  
  

These are not diagnostic indicators. However, they have led many people, especially women over 35, to ask providers about NAD+ injections or supplements.

‍

What Are NAD+ Injections?

NAD+ injections are a prescription-only therapy delivered subcutaneously (just under the skin). Unlike oral supplements, these injections bypass the digestive system and are being studied for their potential to offer more direct delivery than oral supplements.

‍

While NAD+ injections are not FDA-approved to treat or prevent any condition, some individual experiences report:

• More stable daily energy
  
• Enhanced focus or productivity
  
• Better post-exercise recovery
  
  

It’s important to note that experiences vary. That’s why Eden offers access to licensed providers who can assess whether NAD+ injections make sense as part of your wellness plan.

NAD+ Injections vs Other Support Methods

NAD+ can be supported in a few ways:

• Dietary changes (foods high in B vitamins)
  
• Exercise and intermittent fasting, which may help preserve natural levels
  
• Over-the-counter supplements with NAD+ precursors like Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN), meaning they are compounds that the body can convert into NAD+ to help maintain or increase its levels.
  
• Prescription NAD+ injections, available through clinician-guided care
  
  

Each method has its own benefits. However, if you want better absorption or more reliable results, NAD+ injections may be worth discussing with a medical provider.

Final Thoughts

If you’ve been feeling low on energy or looking to support your body’s natural resilience, NAD+ could be a conversation worth having with your provider.

NAD+ doesn’t promise miracles, but it plays a central role in how your cells function. By understanding what NAD+ does and how it changes over time, you can make better choices about supporting your wellness from the inside out.
