Researchers find NAD+ could promote healthy aging, treat diseases

The small molecule has been hailed as a possibility Promote longevity And combat certain diseases, but experts also call for more research.

NAD+ (Nicotinamide Adenine Dinucleotide) – often called the “fountain of youth” – is an essential coenzyme for cell survival, which naturally declines with age. In recent years, supplements designed to boost NAD+ levels have increased in popularity.

Last month, researchers led by the University of Oslo reviewed preclinical trials and Clinical studies Investigating the relationship between NAD+ and aging.

The review, published in the journal Nature Aging, concluded that restoring NAD+ levels could help promote healthy aging and potentially slow or treat neurodegenerative diseases.

Every cell in the body contains NAD+, which plays a “critical role” in body functions necessary for survival.

Previous research has shown that patients with Alzheimer’s disease The researchers noted that they had “significantly lower levels” of NAD+, which is consistent with the fact that NAD+ decreases with age.

“NAD+ may hold the key to healthier aging and can protect us from diseases such as Alzheimer’s and Alzheimer’s disease Parkinson’s disease“However, we need more research on how to effectively use NAD+ in treating patients,” Evandro Fai-Vang Stavem, an associate professor at the University of Oslo, said in a press release.

Benefits of NAD+

Research has shown that boosting NAD+ can improve mitochondrial and stem cell function, improve energy metabolism, enhance focus and mood, and support tissue repair, according to Dr. Amanda Khan, an internist and board-certified longevity expert in New York City.

“From a longevity standpoint, NAD+ is one of the most central molecules in maintaining youthful cellular function,” she told Fox News Digital. “It activates longevity pathways that protect against DNA damage and inflammation.”

Boosting NAD+ also supports neuroprotection against Alzheimer’s and Parkinson’s disease, enhances insulin sensitivity, reduces inflammation, repairs skin, enhances immune defense and improves symptoms in long Covid patients, Kan added.

Dr. Haaland Chen, a double-board-certified physician in New York who specializes in longevity, emphasized that animal studies and early human models show that maintaining healthy NAD+ levels can improve energy metabolism, cognitive function, and overall vitality.

“NAD+ recovery “It’s ultimately about repairing cells and improving mitochondria, not just increasing energy,” he told Fox News Digital. “Clinical experience shows that NAD+ therapy boosts energy, focus and endurance, while supporting detoxification and reducing oxidative stress resulting from everyday life, travel or lack of sleep.”

NAD+ also activates sirtuins, a group of longevity-associated proteins that regulate cellular DNA repair Stress responses Genes and gene expression, Chen said, although he noted that larger human studies are still needed.

Ways to boost NAD+

In clinical studies, patients with age-related diseases took compounds designed to boost NAD+.

While NAD+ itself is a large molecule that cannot cross into cells, NAD+ “precursors” can enter cells and then work to create NAD+, experts stress.

These precursors include nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Most people take these NAD+ precursor In the form of pills, capsules or powders.

“Clinical experience shows that NAD+ therapy enhances energy, focus, and endurance while supporting detoxification.”

“Oral NAD precursors can raise NAD+ levels modestly and are convenient for daily maintenance,” Khan said. “In contrast, an injection or intravenous infusion bypasses the gut and introduces NAD+ directly into the circulation, resulting in more rapid and noticeable effects on energy, focus, and recovery.”

Khan also prescribes a weaker NAD+ nasal spray for patients who can’t tolerate needles, though she said the benefits are usually less clear.

“In general, I find that combining weekly oral NAD+ precursors with weekly NAD+ injections provides the most comprehensive support for both intracellular and extracellular NAD stores,” she advised.

Oral supplements are best for maintenance, while intravenous therapy is often chosen for “rapid cellular reboot, post-travel recovery, or performance enhancement,” Chen noted.

“Sessions typically last two to four hours and are administered as a series of three infusions over seven to 10 days, followed by monthly maintenance.”

“For healthy adults, the benefits are usually modest, but can be amplified when combined with optimal nutrition, exercise and sleep,” he added.

Risks and warnings

While NAD+ therapy is generally safe and well-tolerated, it can cause some mild side effects, according to Chen.

“Headaches, nausea, or chest tightness can occur, especially during faster IV infusions, and usually go away when the rate slows,” Chen, who is also chief medical innovation officer at digital wellness platform Eden, told Fox News Digital.

“Intravenous injections or infusions bypass the gut and deliver NAD+ directly into the circulation, resulting in more rapid and noticeable effects on energy, focus and recovery,” one doctor said. (Istock)

The doctor added: “Most reactions are transient and self-limiting, and treatment is considered safe under medical supervision.”

Khan noted that common side effects include: Slight redness– Itching or pain at the injection site, which is harmless and disappears quickly.

“Some patients notice a transient rush, lasting no more than 10 minutes, after taking an NAD+ injection due to a brief release of adrenaline and mitochondrial ATP,” she continued. “Although it’s not dangerous, it can feel uncomfortable if it’s unexpected.”

“If the foundational pillars – sleep, movement, nutrition, metabolic balance and stress regulation – are not in place, NAD+ therapy will not achieve its full potential.”

When choosing a NAD+ product, quality is more important than quantity, according to many experts.

“Patients should look for formulations that are clinically validated and third-party tested and start with lower doses to gauge their tolerance,” Chen said.

NAD+ therapy is not an abbreviation for Health and longevity By itself, but one layer of foundation is much larger, according to the expert.

“If the cornerstones — sleep, movement, nutrition, metabolic balance, and stress regulation — are not in place, NAD+ therapy will not achieve its full potential,” he said. “It’s like pouring high-quality fuel into an engine that hasn’t been maintained — the power source is there, but the system isn’t optimized for its use.”

According to experts, NAD+ therapy is not a shortcut to health and longevity per se, but one layer of a much larger foundation. (Istock)

It’s important to talk to your doctor before starting an NAD+ diet, experts agree.

“Your doctor needs to know about all the supplements you plan to take, including NAD+, because they have powerful biological effects,” Chen said. “Your doctor will evaluate your personal health risks and… Check your medications For potential interactions with NAD+ supplements.”

Because NAD+ interacts with metabolic and cellular pathways, dosing and timing must be individualized — “particularly for those with a history of cancer, metabolic conditions, or multiple medications,” Khan noted.

“The doctor should help determine the appropriate mode of delivery and duration and monitor response and tolerance,” she said.
