NAD+ Therapy in McAllen, Texas

Clean energy. Clear focus. Cellular support.

At Elite Functional Health in McAllen, Texas, we offer several ways to receive NAD+ Therapy, including intravenous (IV), intramuscular (IM), subcutaneous (Subq), and sublingual forms.

NAD+ supports natural energy production in the body and helps cells work at their best. Many people choose this therapy when they want steady energy, better focus, or support for healthy aging. These options let you choose the method that suits your comfort level, and each delivers NAD+ in a way your body can use effectively. This therapy does not require a long recovery time, which makes it easy to fit into daily life.

What Is NAD+ Therapy?

NAD+ Therapy gives your body a natural helper: NAD+, a molecule every cell needs to make energy. As people get older, NAD+ levels drop, which can make the body feel tired and slow.

How it works

  • NAD+ helps your cells create clean energy
  • It supports healthy cell repair and healthy aging
  • It helps the brain stay clear and focused

Why people use it

Many people choose NAD+ Therapy when they want more steady energy, better focus, or support for healthy aging. It can also help the body handle stress and recover more smoothly.

Ways to receive it

NAD+ can be given intravenously (IV), intramuscularly (IM), subcutaneously (Subq), or sublingually. Each option helps the body use NAD+ in a simple and effective way.

Benefits of NAD+ Therapy

What To Expect

Each NAD+ Therapy session takes 30–60 minutes. You’ll relax while your provider delivers NAD+ via IV, IM, Subcutaneous, or sublingual routes. NAD+ supports cellular energy production, with many describing a calming, steady experience. 


For best results, we recommend a series of sessions spaced 1 to 2 weeks apart, plus occasional maintenance to sustain energy, focus, and healthy aging.

I had an excellent experience at my appointment. The staff was welcoming, professional, and made me feel comfortable from the moment I walked in. The doctor took the time to listen to my concerns, explained everything clearly, and answered all of my questions without making me feel rushed. I truly appreciated the level of care, compassion, and attention I received. It's refreshing to find a medical team that genuinely cares about their patients.

MIRACLE WORKERS
I came to Dr Tagle a broken shell of myself. I no longer recognized my body—or even my personality. From the very beginning, the team reassured me that within 12 weeks I would start feeling better, but it didn’t take nearly that long.

By week six, my health had completely turned around. I had hope again. My brain felt like it was connecting, my feet were finally on solid ground, and my health was moving in the right direction. For the first time in a long time, I felt like myself again.

What stood out most was the thoughtful, root-cause approach to healing—without the endless pharmaceuticals, referrals, and testing that conventional medicine so often relies on. I felt truly seen, heard, and guided with intention.

I am deeply grateful for the care, expertise, and compassion I received. This experience truly gave me my life back.

Dr. Tagle is more than just a physician—he is a genuine healer. In a world where 'profit over patient' is the standard, his practice is a powerful, life-changing exception.

Me, my son and my husband Joe leave his office not only with fewer prescriptions, but with a heart full of hope and a clear plan to defy the odds. The results speak for themselves.

His entire staff is incredibly competent and clearly loves and respects him as much as his patients do, which creates such a warm and positive environment.

Dr. Tagle and his wife Marissa Tagle PA, are a true gift to the RGV community, healing bodies and blessing families with their functional medicine approach.

I highly recommend them to anyone seeking true health restoration.

Excellent experience and treatment overall. From the moment I walk in to the end of my therapy sessions, I'm treated with such kindness and genuine care. Dr. Tagle and his team are incredibly attentive and very professional. Never once have I felt like I was just another number / patient. They give me honest feedback and take my injuries seriously. What more can one ask for? Now healing may be a long road, but Im in the right hands. Coming to Dr. Table's office definitely brings more peace and ease to my body and mind. Ty Dr. Tagle and team!!!!!!!!! ☺️🤗

I was in an accident this past weekend and had to come see a chiropractic, I have to say this was the best choice I've made. Dr. Tagle and staff are very courteous and extremely professional. I highly recommend them for any chiropractic need. If they had the choice of 10 stars I would of definitely given them the 10!!
