TIRED ALL THE TIME? THE PROBLEM MIGHT BE DEEPER THAN YOU THINK.
NAD+ is the molecule your cells need to produce energy, repair DNA, and keep you functioning at full capacity. After 40, your levels drop fast. We put them back. Newport Beach.
The Molecule Behind
Cellular Energy.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of your body. It's essential for converting food into energy, repairing DNA, and activating sirtuins — the proteins that regulate aging and inflammation.
The problem: NAD+ levels decline significantly as we age. By age 50, most people have half the NAD+ they had at 20. This decline is linked to fatigue, cognitive changes, slower recovery, and accelerated aging. At Range Medical in Newport Beach, we offer clinical protocols to restore your NAD+ levels through IV infusions and injections.

How NAD+ Actually
Enters Your Cells.
For years, scientists believed NAD+ couldn't cross cell membranes. We now know it enters cells through two distinct mechanisms — which is why IV and injection delivery works.
Direct Uptake via Connexin 43
Research has identified connexin 43 (Cx43) hemichannels as a direct pathway for NAD+ to enter cells. These protein channels in cell membranes allow intact NAD+ molecules to pass through directly, bypassing the need for conversion. This mechanism is particularly active in cardiac and muscle tissue.
CD73 Conversion Pathway
The second pathway involves enzymes on cell surfaces (CD38 and CD73) that break down extracellular NAD+ into smaller precursors — nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). These precursors easily cross cell membranes and are reassembled into NAD+ inside the cell.
Both pathways work simultaneously, which is why IV and injection NAD+ therapy effectively raises intracellular NAD+ levels — something oral supplements struggle to achieve.
Signs Your NAD+ Levels
May Be Depleted.
NAD+ depletion shows up in many ways. If any of these sound familiar, NAD+ therapy at our Orange County clinic may help.
Two Proven Approaches
to Restore NAD+.
We offer two clinical protocols for NAD+ restoration. Both are effective — the right choice depends on your goals and lifestyle.
Subcutaneous NAD+ injections you administer at home. Convenient, consistent, and effective for building and maintaining NAD+ levels over time.
- Self-administered subcutaneous injections
- Gradual, sustained elevation of NAD+ levels
- Flexible scheduling — do it on your time
- Lower cost per dose than IV
Front-loaded IV infusions for rapid NAD+ restoration. Five sessions over 10 days, then one maintenance IV per month. Repeat the front-load quarterly.
- Higher dose per session (250-500mg)
- Rapid restoration of NAD+ levels
- In-clinic sessions with medical supervision
- Quarterly front-load for sustained results

WHAT WE WANT YOU TO KNOW UPFRONT.
NAD+ is one of the more intense IV infusions — you will likely feel something during the session. That is normal, expected, and manageable. Your nurse adjusts the drip rate to keep you comfortable.
A heavy or constricting feeling in your chest during infusion. Not cardiac — it is the NAD+ itself. Goes away instantly when the drip slows.
Queasy stomach if the drip rate is too fast. Completely rate-dependent — slowing the drip fixes it every time.
Warmth spreading through your body from NAD+-related vasodilation. Same mechanism as a niacin flush. Harmless.
Feeling tired after your session. Your body is using the NAD+ for cellular repair. The energy boost comes 24-48 hours later.
Currently taking blood pressure medications (NAD+ can affect blood pressure)
History of heart arrhythmias or cardiac conditions
Pregnant or breastfeeding
Active infections or fever
Currently on chemotherapy or immunosuppressive medications
NAD+ therapy is not FDA-approved for specific conditions. All infusions are administered and monitored by licensed medical professionals. We assess every patient before starting.
WHAT PATIENTS FEEL AFTER
THEIR FIRST PROTOCOL.
These are real outcomes from real patients. Names withheld for privacy — results speak for themselves.
NAD+ levels drop by roughly 50% between ages 40 and 60. This decline directly impacts energy production, DNA repair, cognitive function, and cellular aging. Your body can't manufacture enough to keep up with demand. Every year you wait, the deficit grows. NAD+ therapy restores what your cells need to function at their best — but restoration is easier when you start before the tank hits empty.
Common
Questions
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It's essential for energy production, DNA repair, cellular signaling, and activating sirtuins — proteins that regulate aging. As we age, NAD+ levels decline significantly, which is linked to many age-related issues.
Oral NAD+ has very poor bioavailability — most of it is broken down in the gut before reaching your bloodstream. IV and injection delivery bypass the digestive system entirely, delivering NAD+ directly to your bloodstream where it can reach your cells. This is why clinical protocols use IV or injection routes.
Both are effective. The injection protocol (3x/week for 12 weeks) offers convenience and gradual building of NAD+ levels. The IV protocol provides higher doses per session and a front-loaded approach. We'll recommend based on your goals, schedule, and how you respond to treatment.
NAD+ IVs are infused slowly over 2-4 hours. Some people experience flushing, chest tightness, or nausea if infused too quickly — this is why we go slow. Most patients describe feeling energized and mentally clear after their infusion. The sensation is temporary and manageable.
Individual results vary, but most patients report sustained benefits for 2-4 weeks after completing a protocol. This is why we recommend maintenance sessions (monthly IV or continued injections) to maintain elevated NAD+ levels long-term.
Yes, when administered by trained medical professionals. NAD+ is a naturally occurring molecule in your body — we're simply replenishing what declines with age. Side effects are typically mild and transient. We monitor you throughout IV infusions and adjust the rate as needed.
