What Is the Standard NAD+ Injection Dosage?

Aging is something that affects all living things. Fortunately, with innovations in modern medicine, many of the effects of aging can be slowed. Supplements like NAD+ have played a key role in this regard and have become a popular choice for people of all ages.

If you are considering this option, you may be wondering about NAD+ injection dosage. The right amount depends on a variety of factors.

The good news is that, once you know what these variables are, you can have a better idea of how much NAD+ is right for you. This article covers those. Keep reading to find out what they are and how they relate to your personal health goals.

What Is NAD+?

NAD stands for "nicotinamide adenine dinucleotide." It is a vital coenzyme found in every cell in the human body.

There are two forms of NAD. Reduced NAD, or NADH, are molecules that donate electrons during redox reactions. Those that receive electrons are known as NAD+.

NAD plays a critical role in many biological processes. These include metabolism, energy production, and DNA repair. Each of these plays a direct role in overall health as well as longevity.

It does so by working as an electron carrier during oxidation-reduction (or "redox") chemical reactions. It shuttles electronics between molecules in metabolic pathways. This event supplies energy for important cellular processes.

NAD+ also may play a role in maintaining sirtuins and telomeres. These are proteins that are also linked to longevity.

What Negatively Impacts NAD+ Levels?

Many things can cause NAD+ levels to decline. Common ones include stress, insufficient sleep, poor eating habits/malnutrition, and drug and alcohol use. Also, as we age, NAD+ levels decline naturally, regardless of our lifestyle or relative level of health.

This leads to fatigue, cognitive decline, and a weakened immune system. It can also lead to neurodegeneration, which is related to diseases like Parkinson's, Alzheimer's, and other forms of dementia.

What Are the Health Benefits of NAD+ Supplements?

There are many benefits to taking NAD+ supplements. Some people do so to address diminished metabolism and energy levels.

For this reason, people of all ages use NAD+ to improve athletic performance and recovery. This makes it a promising supplement for weight loss or healthy weight maintenance.

NAD+ supplementation may also slow cellular processes associated with aging. These include DNA repair, gene expression regulation, and mitochondrial function.

Finally, NAD+ can play a role in maintaining neurological health and function, and support brain health. Among other benefits, this can lead to increased mental clarity, alertness, concentration, focus, and alertness.

How Are NAD+ Supplements Taken?

There are several different delivery methods for NAD+ supplements. These include capsules, sublingual tablets, nasal sprays, and injections.

Oral capsules are convenient and easy to take. They must go through the digestive tract though, which means slower and less absorption overall.

Sublingual tablets and nasal sprays are absorbed by mucus membranes and are faster-acting than oral capsules. Injections are the most direct route of administration.

There are two main types of injections: subcutaneous and intravenous (IV). Subcutaneous injections are given in fatty parts of the body, and patients can administer them on their own.

IV infusions mix NAD+ with saline and inject it directly into the bloodstream, making them the most effective type of delivery. However, they must be administered by a health professional.

What Is the Standard NAD+ Injection Dosage?

NAD+ injection dosage can range anywhere from 100 to 1,000 milligrams (mg) per day, although typical daily doses are around 200 to 300 mg. That range is due to several factors. Here are the main ones to consider when taking NAD+ injections.

Method of Delivery

How you take a NAD injection can impact dosage. In general, subcutaneous injections will require a bit more than IV infusions. A related factor is that subcutaneous injections can be taken more often than IVs, which could impact how much you are taking with each one.

With other delivery methods, you will likely need higher doses (due to lower absorption rates). This is especially true for oral supplements; less so for sublingual tabs. Nasal sprays can deliver absorption rates on par with subcutaneous injections but usually have a specific dosage built into the applicator.

Note that some patients combine delivery methods. For instance, they might take sublingual tablets every day or so, with injections given intermittently.


As mentioned, NAD+ levels begin to decline as we age. For this reason, someone over the age of 40 may benefit from a larger NAD+ injection dosage than a younger person. This is especially true if combined with other factors.

General Health

Overall health is another variable that can impact NAD+ dosage. Combatting years of NAD+ degeneration may look different for someone who is looking for a bit of recovery from too much drinking on an isolated occasion, but who otherwise has a healthy lifestyle.

Health Challenges and Goals

A final factor that can impact NAD+ dosage is your particular health goals. This includes what you wish to accomplish through supplementation. For instance, someone with specific health challenges may benefit more from a higher dosage of NAD+ supplements than someone merely trying to maintain health.

Combined Factors

Keep in mind that these factors are cumulative, not isolated. A medical professional will be able to evaluate all factors that may contribute to NAD+ decline and recommend an appropriate dose.

Finally, there could be other underlying factors of which you are unaware. A proper evaluation should unveil these and factor them into the prescription dosage.
