NAD+ Injections vs Supplements: What’s the Difference?

NAD+ Is the Same—But Delivery Matters

Whether you’ve heard about NAD+ in wellness circles, podcasts, or seen it in supplement form at your local store, one thing to know is that how it’s delivered matters.

Both NAD+ supplements and NAD+ injections are designed to support levels of this critical coenzyme. But they differ in how they're delivered—and some individuals explore injections for their potential to bypass digestion.

In this blog, we will explore the differences between oral supplements and injectable forms of NAD+ and discuss why some people choose to work with a provider to customize their plan.

The Basics: What Does NAD+ Do?

NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring molecule in all living cells. It’s essential for:

• Turning food into energy (via ATP production)
• Supporting healthy DNA maintenance
• Involved in metabolic activity and mitochondrial function
• Maintaining healthy cell signaling
  
  

Over time, NAD+ levels naturally decline. A change that may be associated with shifts in energy, physical resilience, and how the body recovers from daily stressors.

That’s why more people are exploring NAD+ support, especially with guidance from a licensed provider. 

Now that we know why NAD+ is crucial for energy and cellular health, let’s explore how you can support your levels. In this post, we’ll compare two common methods—supplements and injections—to help you understand which might be right for you.

NAD+ Supplements: Convenience with Limitations

NAD+ supplements—usually in the form of NR (nicotinamide riboside) or NMN (nicotinamide mononucleotide)—are available over the counter. They work by giving your body the building blocks to make NAD+ naturally.

Benefits:

• Easy to purchase and take
• Can be incorporated into daily routines
• May be suitable for early-stage wellness support
  
  

Limitations:

• Must pass through the digestive system, where absorption may be affected by the body’s natural processes
• Absorption rates can vary by person
• Dosing is often generalized rather than personalized
  
  

While some users feel benefits, others don’t notice a change, especially if their digestion or metabolism isn’t efficiently converting precursors into usable NAD+.

NAD+ Injections: Direct Delivery, Guided by Providers

NAD+ injections are administered subcutaneously (just under the skin), allowing for more controlled absorption.

Benefits:

• Bypasses the digestive tract, which may support more direct delivery
• Dosing can be personalized based on goals and tolerance
• Prescribed and monitored by a licensed provider
  
  

Limitations:

• Requires a prescription
• Not available in retail stores
• May require some at-home administration training
  
  

Some individuals report more noticeable benefits with injections, such as steadier energy, quicker recovery, or improved mental clarity. That said, these outcomes vary and are based on individual experience.
