If you’ve been feeling more tired than you used to, finding it harder to concentrate, or noticing that your metabolism isn’t what it was a decade ago, you’re not imagining it. Part of the story may come down to a molecule most people have never heard of: NAD+.

NAD+ has become one of the most talked-about topics in longevity and wellness medicine, and for good reason. In this guide, we’ll explain what NAD+ is, why levels drop as we age, the potential benefits of NAD+ injections, and how MedShape Weight Loss Clinics offers clinician-guided NAD+ therapy in Arizona, Minnesota, and nationwide by telehealth.

What Is NAD+?

NAD+ stands for nicotinamide adenine dinucleotide. It’s a coenzyme found in every living cell in your body, and it plays a role in hundreds of biological processes. Its most important jobs include:

  • Energy production: NAD+ helps your mitochondria convert the food you eat into ATP, the fuel your cells run on.
  • DNA repair: Enzymes that repair damaged DNA depend on NAD+ to do their work.
  • Cellular signaling: NAD+ supports sirtuins, a family of proteins linked to metabolism, inflammation, and cellular aging.

In short, NAD+ helps keep your cells running, repairing, and communicating the way they should.

Why NAD+ Levels Decline With Age

Research shows that NAD+ levels naturally fall as we get older. Some studies suggest levels in middle age may be significantly lower than in young adulthood. Beyond age, NAD+ can also be depleted by:

  • Chronic stress
  • Poor sleep
  • Excess alcohol
  • High-sugar, highly processed diets
  • Inflammation and illness
  • Environmental exposures

When NAD+ runs low, cells have less capacity to produce energy and repair themselves. Many researchers believe this decline contributes to common signs of aging, from fatigue and brain fog to slower metabolism.

6 Potential Benefits of NAD+ Injections

NAD+ research is an active and growing field. Much of the strongest evidence still comes from laboratory and animal studies, and human research is ongoing. That said, here are the areas where NAD+ shows the most promise and where patients most often report results.

1. More Energy and Less Fatigue

Because NAD+ is central to how your body makes ATP, restoring levels may help support steady, natural energy. Many MedShape patients say reduced fatigue and better stamina are the first things they notice, rather than the jittery spike you’d get from caffeine.

2. Sharper Mental Clarity and Focus

Your brain is one of the most energy-hungry organs in the body. NAD+ supports brain metabolism and healthy neuron function, which is why many people pursue NAD+ therapy for clearer thinking, better focus, and improved mood.

3. Support for Healthy Aging

NAD+ fuels the enzymes responsible for DNA repair and activates sirtuins, sometimes called “longevity proteins.” Replenishing NAD+ is one of the most studied strategies in anti-aging medicine for supporting cellular health as we age.

4. Metabolic Health and Weight Management

Early research links NAD+ to improved insulin sensitivity and more efficient fat metabolism. NAD+ is not a weight loss drug on its own, but it can be a smart complement to a structured program. At MedShape, NAD+ pairs well with our Semaglutide and Compound Tirzepatide GLP-1 programs, helping patients feel energized while they lose weight.

5. Exercise Performance and Recovery

Better cellular energy may translate into better workouts and faster recovery. Patients who are increasing their activity as part of a weight loss plan often appreciate the extra stamina.

6. Resilience Against Everyday Stress

Since stress, poor sleep, and alcohol all drain NAD+, replenishing it may help your body bounce back more effectively from the demands of a busy life.

NAD+ Injections vs. NAD+ Supplements

You’ll find plenty of oral NAD+ “precursor” supplements, such as NMN and NR, on store shelves. These supply building blocks your body may convert into NAD+. Injections take a more direct route: subcutaneous NAD+ injections deliver NAD+ itself and bypass the digestive system, so your body doesn’t have to break down and rebuild it first.

Injections also come with something supplements don’t: medical oversight. At MedShape, a licensed clinician reviews your health history and sets your dose, rather than leaving you to guess.

How NAD+ Therapy Works at MedShape

MedShape has helped more than 300,000 patients since 2004, and our NAD+ program follows the same clinician-led approach behind our weight loss programs.

1. Free consultation. A MedShape clinician reviews your health history and goals to decide whether NAD+ is right for you. Visit one of our clinics in Mesa, Scottsdale, or Peoria, Arizona, or Maple Grove or Eagan, Minnesota, or meet by nationwide telehealth from anywhere in the U.S.

2. Loading phase. Twice-weekly injections over several weeks help bring depleted NAD+ levels back up.

3. Maintenance. Once-weekly injections help sustain your levels over the long term.

NAD+ injections are subcutaneous, a small shot just under the skin that most patients describe as minimally uncomfortable. You can self-inject at home or visit a clinic, and you can go right back to your day afterward.

Pricing: MedShape’s NAD+ injections start at $139 per month, including your consultation, a personalized protocol, and ongoing clinical support. Flexible payment is available through Cherry Financing.

Who Is a Good Candidate for NAD+?

NAD+ therapy may be a good fit if you:

  • Feel persistently low on energy
  • Struggle with brain fog or focus
  • Want to support healthy aging
  • Are on a weight loss program and want more energy along the way
  • Lead a high-stress lifestyle

NAD+ isn’t right for everyone. Your MedShape clinician will review your medical history, current medications, and goals before recommending treatment.

Frequently Asked Questions About NAD+

How soon will I notice the benefits of NAD+?

Many patients report more energy and mental clarity within the first few days. Deeper benefits typically build over several weeks of consistent therapy. Results vary from person to person.

Are NAD+ injections safe?

When prescribed and monitored by a licensed clinician, NAD+ injections are generally well tolerated. Possible side effects can include mild injection-site discomfort, flushing, or nausea. Your MedShape clinician will review your health history to make sure NAD+ is appropriate for you.

Can I combine NAD+ with Semaglutide or Tirzepatide?

Yes. NAD+ is commonly paired with MedShape’s GLP-1 weight loss programs and peptide therapies. Your clinician will help you build an integrated plan.

Can I get NAD+ injections without visiting a clinic?

Yes. MedShape offers nationwide telehealth, so you can start NAD+ therapy from home anywhere in the U.S.

How much do NAD+ injections cost?

MedShape’s NAD+ injections start at $139 per month, with financing available through Cherry.
