NAD+ Injection vs Spray

April 14, 2025

At Seven Cells, we offer two easy-to-use options for NAD+ supplementation: injections and nasal spray. Both are designed to help support your energy, focus, and overall wellness, but they work a little differently. Choosing the right one depends on your lifestyle, preferences, and how quickly you’re looking to feel results.

If you’ve been searching for a way to feel more energized, mentally sharp, and physically resilient, especially as the years go by, you’ve probably come across something called NAD+. It’s been gaining attention lately, and for good reason. NAD+ is a naturally occurring molecule found in every cell of your body. It plays a key role in producing energy, repairing cells, and even slowing signs of aging.

But as with most good things, our natural supply of NAD+ declines over time. That drop can leave you feeling tired, foggy, or just not quite like yourself. That’s where NAD+ supplementation comes in—to help replenish your levels and support the way your body and mind function every day.

What’s the Difference Between Injections and Spray?

Both our injection and spray options provide NAD+, but the experience and effects can feel quite different.

Injections

Fast-acting: Injecting NAD+ directly into your bloodstream means your body can use it right away.
High potency: You’re getting a concentrated dose for quicker, more noticeable results.
At-home convenience: No clinic visits or appointments—administer it yourself safely at home.
Ideal for: People who want stronger effects, have used NAD+ before, or prefer results they can feel quickly.

Things to consider:

You’ll need to be comfortable using a small needle (we provide easy-to-follow instructions).
Some users may experience mild injection-site tenderness.

NAD+ Nasal Spray

Easy to use: A couple sprays into your nostrils, and you’re good to go.
Needle-free: Great for those who aren’t fans of injections.
Portable: Keep it with you at work, in your gym bag, or while traveling.
Ideal for: New NAD+ users, people looking for everyday support, or anyone wanting a gentler approach.

Things to consider:

Effects can be more gradual.
You may need to use it more frequently to maintain levels.
Absorption varies slightly from person to person.

What Is NAD+ and Why Do You Need It?

NAD+ stands for nicotinamide adenine dinucleotide. It’s a coenzyme that’s found in every cell of your body. While it may not be something you think about every day, your body relies on it constantly. Here's what it helps with:

Turning food into usable energy (cellular metabolism)
Supporting DNA repair and cellular health
Promoting mental clarity and focus
Aiding in muscle recovery and resilience
Contributing to healthy aging and longevity

Unfortunately, NAD+ levels decline as we age. That dip can lead to lower energy, brain fog, and slower recovery—all of which are reasons people start looking into NAD+ therapy.

Who Typically Uses NAD+?

People from all walks of life are turning to NAD+ to feel and function better. Common users include:

Busy professionals dealing with long hours and mental fatigue
Athletes and gym-goers looking to improve recovery and performance
Biohackers and longevity seekers aiming to age well and stay sharp
People recovering from burnout, illness, or high stress who want to feel more balanced and energized

NAD+ isn’t a miracle cure—but for many, it’s a valuable tool to support everyday performance and well-being.

Injection or Spray?

NAD+ can play a big role in how we feel, think, and recover. Whether you choose the quick-hit power of an injection or the simple convenience of a nasal spray, you’re giving your body support where it needs it most. Both options are safe, easy to use, and available for at-home use—no trips to the doctor’s office required.
