NAD+ for athletes: Recovery, performance, and what the science says

The Recovery Wall Every Athlete Hits

Five training sessions a week. Sleep dialed in. Macros tracked to the gram. And still, by Thursday, your legs feel like they belong to someone else.

If you train in Los Angeles, you know this cycle. Maybe you’re a CrossFit athlete in Santa Monica grinding through double sessions. Maybe you’re a marathon runner logging miles through Griffith Park, watching your pace plateau despite doing everything right. Or maybe you surf Malibu mornings and lift in the afternoon, and your body has started pushing back.

The frustrating part isn’t the soreness. It’s the gap between how hard you’re willing to work and how fast your body can keep up. Recovery becomes the bottleneck. Not effort. Not discipline. Not programming.

That gap has pushed a growing number of competitive and recreational athletes toward a molecule that sits at the center of cellular energy production: nicotinamide adenine dinucleotide, or NAD+. It’s not a supplement trend or a biohacking gimmick. It’s a coenzyme your body already produces, one that declines with age and intense physical stress, and one that researchers are studying for its role in everything from mitochondrial function to DNA repair.

Here’s what the science says about NAD+ and athletic performance, what it may do for recovery, and why athletes across Los Angeles are making it part of their training protocols.

What NAD+ Does at the Cellular Level

NAD+ is a coenzyme found in every living cell. It plays a central role in metabolic processes, particularly the conversion of nutrients into adenosine triphosphate (ATP), the energy currency your muscles depend on during every rep, sprint, and mile.

Inside the mitochondria, NAD+ acts as an electron carrier in the process of oxidative phosphorylation. Without adequate NAD+ levels, this process slows down. Less ATP gets produced. Your cells generate less energy, and your body feels the difference during training and recovery.

But NAD+ does more than fuel your workouts. It activates a family of proteins called sirtuins, which regulate cellular repair, inflammation response, and gene expression. Sirtuins depend on NAD+ to function. When NAD+ levels drop, sirtuin activity drops with them, and your body’s ability to repair damaged tissue and manage oxidative stress weakens.

NAD+ also supports poly(ADP-ribose) polymerases, or PARPs, enzymes responsible for DNA repair. Intense exercise creates oxidative stress and micro-damage at the cellular level. PARPs consume NAD+ to fix that damage. The harder you train, the more NAD+ your body burns through.

Here’s the problem: NAD+ levels decline with age. Research published in Cell Metabolism has documented a steady reduction in NAD+ concentrations as humans age, starting as early as your 30s. Combine that natural decline with the increased NAD+ demand from high-intensity training, and you get a compounding deficit.

Your body produces less NAD+ over time. Your training consumes more of it. The math stops working in your favor. That’s the biological foundation behind the recovery wall so many athletes hit, and it’s the reason NAD+ supplementation has attracted serious scientific attention.

Why Athletes Are Turning to NAD+

The interest in NAD+ among athletes is mostly about the research below. Most of it is early, and none of it is a promise about what a single IV session does.

Recovery between sessions. Sirtuin-mediated repair processes depend on NAD+. Researchers are studying whether higher NAD+ levels shorten the time the body needs between hard training days; the human evidence is limited.

Mitochondrial support for endurance. Endurance athletes depend on mitochondrial density and efficiency. NAD+ is a required input for mitochondrial energy production. Studies in animal models have shown that raising NAD+ levels may improve mitochondrial function and exercise capacity. Human research is still developing, but the mechanistic pathway is well established.

Reduced inflammation markers. Hard training creates systemic inflammation. That’s a normal part of the adaptation process, but chronic inflammation from overtraining or inadequate recovery becomes a performance limiter. NAD+ supports anti-inflammatory pathways through sirtuin activation, which may help keep inflammation in a productive range rather than a destructive one.

The athletes pursuing NAD+ in Los Angeles aren’t fringe biohackers. They’re marathon runners in training for the LA Marathon. They’re surfers who want to paddle out at dawn and still hit a lifting session before lunch. They’re weekend warriors hiking Runyon Canyon who want their legs fresh for Monday’s gym session. They’re rock climbers in the San Fernando Valley and yoga practitioners in West Hollywood who want their bodies to match their ambitions.

The common thread: they are looking past nutrition, sleep and programming.

NAD+ IV vs. Oral NAD+ Supplements for Athletes

If NAD+ matters, the next question is how to get more of it. Two primary options exist: oral supplements (NR and NMN precursors) and intravenous NAD+ infusions. The difference between them is significant, and for athletes operating on tight recovery timelines, that difference matters.

Oral NAD+ precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) must survive the digestive tract, get absorbed through the intestinal lining, travel through the liver, and then convert into NAD+ through a multi-step enzymatic process. Published bioavailability estimates for oral NR and NMN range from roughly 2% to 10%. That means for every 500mg capsule you swallow, your cells may receive 10 to 50mg of usable NAD+.

IV administration bypasses the entire digestive system. NAD+ enters the bloodstream directly and reaches cells. No conversion steps. No absorption losses. No first-pass metabolism in the liver.

For an athlete trying to recover between a Saturday race and a Monday training session, the delivery speed matters as much as the dose. Oral supplementation builds NAD+ levels gradually over weeks. IV delivery raises circulating NAD+ within hours.

That doesn’t make oral supplements worthless. Many athletes use daily NR or NMN as a maintenance strategy and schedule IV NAD+ sessions during heavy training blocks, competition season, or when recovery demands spike. The two approaches complement each other.

The cost difference reflects the delivery advantage. A month of quality NMN capsules runs $50 to $150. A single NAD+ IV session through Instadrip costs $699.

What to Expect from an NAD+ IV Session

If you’ve never done an NAD+ IV infusion, here’s what the process looks like with Instadrip.

You book online or by phone. Choose your location: your home, your gym, your office, your hotel room. Instadrip is a mobile IV therapy service, so the session happens wherever you are in the greater Los Angeles area.

A licensed registered nurse arrives at your scheduled time with all supplies. They’ll review your health history, check your vitals, and set up the IV line. The NAD+ infusion itself takes between 2 and 4 hours depending on the dose and your tolerance. This is not a 30-minute drip. NAD+ must be infused slowly to avoid discomfort.

During the session, you may experience a “flush” sensation: warmth in your chest, a tingling feeling, or mild nausea. This is a normal response to NAD+ entering the bloodstream and typically passes within minutes. Your nurse can adjust the drip rate to keep you comfortable.

Most people use the infusion time to work, read, watch something, or rest. You don’t need to clear your schedule beyond the session itself.

Afterward, you go back to your day. Responses vary from person to person, and NAD+ IV therapy does not replace the work you put in at the gym.

Pricing: NAD+ IV therapy is $699 for 500mg, or $1,200 for 1000mg.

NAD+ Across Los Angeles for Athletes

One of the advantages of mobile IV therapy is that your session comes to you. Instadrip serves athletes throughout the greater Los Angeles area, and different neighborhoods bring different training cultures.

Santa Monica. Beach runners, ocean swimmers, and outdoor CrossFit athletes who train hard in the salt air and need recovery that matches their volume.

West Hollywood. Home to some of LA’s best gyms and personal training studios. Bodybuilders, physique competitors, and serious lifters book NAD+ during prep seasons.

Beverly Hills. Personal trainers, celebrity fitness coaches, and clients who expect peak performance from their bodies and their recovery protocols.

NAD+ and Long-Term Health: What the Research Covers

Athletic performance isn’t separate from long-term health. The same cellular mechanisms that determine how fast you recover from a hard workout also influence how your body ages.

The sirtuin pathways NAD+ activates are the same ones researchers study in the context of aging. That research is early, and Instadrip makes no anti-aging claim for an NAD+ session.

If you’re interested in the longevity angle, our deep dive into NAD+ and Anti-Aging Science covers the research in detail.

Frequently Asked Questions

How much does NAD+ IV therapy cost for athletes?

NAD+ IV therapy through Instadrip costs $699 for 500mg, or $1,200 for 1000mg. There’s no separate pricing for athletes vs. non-athletes. The NAD+ protocol is the same.

How often should athletes get NAD+ IV therapy?

Most athletes start with a loading phase of 2 to 4 sessions over 2 weeks, then shift to monthly maintenance sessions. During heavy training blocks or competition season, some athletes schedule sessions every 2 weeks. Your nurse can help you build a schedule that matches your training calendar.

Can I get NAD+ IV therapy before a race or competition?

Yes. Some athletes schedule a session 2 to 3 days before a race. Avoid scheduling the day before or day of competition, as the infusion takes 2 to 4 hours and the flush sensation during the drip may cause temporary discomfort.

Is NAD+ IV therapy safe for athletes?

NAD+ is a naturally occurring coenzyme in your body. IV administration is performed by licensed registered nurses who monitor your vitals throughout the session. Side effects are mild and temporary: flushing, warmth, mild nausea, or chest tightness during the infusion. These resolve when the drip rate is adjusted. NAD+ IV therapy contains no banned substances under WADA or USADA guidelines. However, athletes subject to anti-doping testing should always verify current regulations with their governing body.

How long does an NAD+ IV session take?

A standard NAD+ IV session takes 2 to 4 hours. NAD+ must be infused slowly to maintain comfort and allow your body to process it effectively. Plan to set aside a half day. Many athletes use the time to review training footage, answer emails, or rest.

What’s the difference between NAD+ IV and a regular vitamin IV?

Standard vitamin IV drips, like the Myers Cocktail, deliver a liter of saline with vitamins such as B-complex and vitamin C. NAD+ IV therapy delivers a coenzyme your cells use to make energy, and the session is longer, at two to four hours.

Can NAD+ help with muscle soreness?

NAD+ is a coenzyme your cells use to make energy, but it is not a painkiller or an anti-inflammatory drug, and Instadrip does not claim it reduces soreness.
