NAD+ Therapy in Irvine: Subcutaneous Injections, 15 Minutes South

In short: Irvine patients drive about 15 minutes south on the 5 freeway to reach our Mission Viejo clinic for NAD+ therapy. We give NAD+ as a subcutaneous injection, priced per injection, for routine recovery and energy support. We do not offer IV drips. Late-afternoon weekday slots, up to our 5 PM close, accommodate tech-professional schedules. Evidence is most established for cellular metabolism support; performance and longevity claims are emerging but unsettled.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell. It powers mitochondrial energy production, DNA repair pathways, and sirtuin signaling. NAD+ levels decline measurably with age, which is why supplementation has moved from theory into clinical practice. For the broader peptide and biological-aging context, our peptide therapy guide covers the related compounds.

This page covers how we give NAD+ (by subcutaneous injection), who it fits, what NAD+ does and what it does not, and the logistics of getting here from Irvine.

The Irvine-to-Mission Viejo logistics

Mission Viejo sits about 15 minutes south of Irvine on the 5 freeway, two exits past the Irvine Spectrum. The 73 is an alternative from the western side of Irvine. Surface streets are not faster.

The 5 freeway is heaviest between 4:30 and 6:30 PM southbound. We close at 5 PM, so a mid-day or early-afternoon slot keeps you ahead of that traffic. Mornings before 8:00 AM are also quick.

What NAD+ does (and what it doesn’t)

NAD+ runs three primary cellular jobs:

• Energy metabolism. Mitochondrial electron transport relies on NAD+/NADH cycling to convert glucose and fat into ATP.
• DNA repair. NAD+ is a substrate for PARP enzymes that respond to DNA damage.
• Sirtuin signaling. Sirtuins are a family of enzymes implicated in cellular stress response and gene regulation; they require NAD+ to function.

Established clinical use in routine practice centers on cellular metabolism support, recovery from physical exertion, and adjunctive use in protocols for jet lag, neurocognitive support, and post-illness fatigue. The evidence base is strongest for biochemical effects (NAD+ levels rise, mitochondrial markers shift). It is weaker for longevity outcomes, those studies are still emerging and we will not oversell them.

What NAD+ does not do: it is not a treatment for any specific disease, it does not “reverse aging,” and the more enthusiastic longevity claims circulating on social media are ahead of the published evidence. We tell patients the honest version up front.

Why we give NAD+ by injection

A NAD+ injection takes a few minutes, so most visits are short.

An injection is the sensible entry point: the dose is smaller, the visit is short, and you can build a regular rhythm. Some clinics use IV drips for rapid high-dose loading; we do not offer them.

Why Irvine tech professionals use NAD+

The Irvine corridor, the Spectrum, Discovery Business Center, the Quail Hill area, concentrates a specific patient profile. Knowledge workers in their 30s, 40s, and 50s with high cognitive demand, frequent travel for business, and limited tolerance for being functionally off-baseline. The use cases that come up most often:

• Cognitive performance. Mental clarity, focus, and sustained attention during long work weeks. Most reported as subjective improvement; consistent enough that patients return for it.
• Jet lag. Pre-flight and post-flight protocols around international travel. Patients who fly between California and Asia or Europe report shorter recovery windows.
• Recovery from physical exertion. Triathletes, cyclists, and patients training hard at the gym often add NAD+ around peak training blocks.
• Post-illness fatigue. Patients recovering from viral infections (including long-COVID-style fatigue) sometimes use a short course while rebuilding stamina.
• Hangover / overconsumption recovery. Off-label use, well-known among biohacker patients. We provide it but the conversation includes a moderation discussion.

For patients curious about the broader benefits and dosing logic, our NAD+ injections benefits page covers the science in more depth.

Side effects to expect

• Injection: brief sting at the injection site, occasional mild flushing for 5-15 minutes.
• General: mild fatigue or sleep changes in the first few days are reported by some patients as the body adjusts.

Patients with active malignancy should discuss NAD+ with their oncology team before starting, the pathways NAD+ influences can in theory support healthy cell repair and unhealthy cell proliferation alike. We screen for this at intake.

Weekday hours

We are open Monday through Friday, 9 AM to 5 PM, and hold lunch-hour and late-afternoon slots for working professionals.

Injections can be booked into 10-minute slots during weekday hours. No extended commitment.
