Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every cell of the body and plays a crucial role in energy production, DNA repair, and cell signaling. In recent years, NAD+ has gained popularity as a supplement and as part of various IV therapies that aim to boost energy levels, slow aging, and support recovery from conditions like addiction and neurodegenerative diseases. With such a surge in interest, many potential users have questions regarding its safety and possible side effects. One common question is: Does NAD cause diarrhea? In this post, we will explore the science behind NAD, review the different ways it is administered, discuss common side effects (including gastrointestinal issues) and evaluate whether diarrhea is an expected reaction.
NAD+ is essential for transforming the food we eat into the energy required by our cells. It acts as a helper molecule in redox reactions, transferring electrons from one reaction to another. This process is pivotal for proper mitochondrial function, which in turn supports the body’s metabolism and cellular homeostasis. NAD+ also plays an important role in activating several enzymes—such as sirtuins and poly (ADP-ribose) polymerases (PARPs)—that help repair damaged DNA and modulate inflammation.
Beyond energy metabolism, NAD+ has been heavily researched for its anti-aging properties. As we age, NAD+ levels naturally decline, which may contribute to decreased energy, reduced cellular repair capacity, and various metabolic inefficiencies. Boosting NAD+ levels has thus become of great interest to people who want to support longevity, maintain cognitive function, and improve overall vitality.

Learn MoreThere are several forms of NAD+ supplementation, which vary in terms of delivery and absorption efficiency. The most common methods include:
Oral Supplements: NAD+ precursors such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are often taken in capsule or tablet form. These precursors are converted into NAD+ in the body. Although convenient, oral supplements may have lower bioavailability due to digestive processing.
Intravenous (IV) Therapy: In NAD IV therapy, the NAD+ solution is infused directly into the bloodstream using a properly controlled drip system. This method bypasses the digestive system, ensuring rapid and complete absorption.
Transdermal and Intranasal Delivery: Newer formulations, such as creams, patches, or nasal sprays, provide alternative routes of administration that can target specific tissues or deliver NAD+ directly to the brain.
Each method has its own advantages and potential drawbacks. IV therapy, for instance, tends to offer immediate results and can be tailored to the needs of patients, while oral supplements are more accessible but might take longer to show effects.
When it comes to supplements and IV therapies, side effects are an important aspect of any treatment to consider. Although NAD+ is a naturally occurring coenzyme in our cells, artificially increasing NAD+ levels—especially through high doses—can sometimes lead to side effects as the body adjusts to the influx.
Commonly reported side effects of NAD+ therapies include:
Among the gastrointestinal symptoms, mild digestive disturbances such as nausea and indigestion are relatively common. However, there are questions about whether diarrhea can occur as a side effect of NAD therapy.

Learn MoreThe question “Does NAD cause diarrhea?” often arises during discussions of NAD supplementation, with some individuals reporting loose stools or diarrhea after taking oral NAD+ precursors. It is important to understand that while there have been sporadic reports of gastrointestinal disturbances, including diarrhea, the evidence is not conclusive, and such side effects are generally rare.
Diarrhea as a side effect from NAD+ supplementation is not well-documented in scientific studies. However, several potential mechanisms have been proposed:
Most controlled studies on NAD+ supplementation have reported very few serious side effects. In clinical trials that utilized nicotinamide riboside or NMN, the reported side effects were mostly limited to mild nausea and headaches. Diarrhea, when it occurs, tends to be a transient and self-limiting event.
It is more often seen in cases where individuals either exceed recommended dosages or have sensitive digestive systems. For many users, the benefits of increased NAD+—like enhanced energy, improved cognitive function, and cellular repair—far outweigh the minor risk of experiencing diarrhea.
If you are concerned about gastrointestinal side effects, including diarrhea, here are some strategies to help mitigate the risks:
Start With Lower Doses: Gradually introducing NAD+ supplements allows your body to adjust to the increased levels. Beginning with a lower dose and slowly ramping up can help reduce the likelihood of gastrointestinal upset.
Take With Food: Consuming NAD+ supplements with a meal might reduce any potential osmotic effects in the gastrointestinal tract, thereby minimizing the risk of diarrhea.
Stay Hydrated: Increased water intake can help maintain proper digestion and nutrient absorption, offsetting potential mild dehydration that sometimes accompanies digestive upset.
Monitor Your Body’s Response: Pay attention to how your body responds during the first few days of supplementation. If you notice any significant digestive changes, it may be wise to lower your dose or consult a healthcare provider.
Choose Quality Products: Ensure that you are using supplements from reputable manufacturers. High-quality formulations are more likely to have consistent dosing and fewer contaminants that might exacerbate gastrointestinal symptoms.

Consult a Healthcare Professional: Personalized advice from a qualified provider can help determine whether NAD therapy is appropriate for your health needs and condition. This is especially important if you have underlying medical conditions or are taking other medications.
Understand Your Dosage: The ideal dosage of NAD+ precursors can vary depending on individual factors such as age, weight, health status, and the specific goals of supplementation. Your healthcare provider can guide you in optimizing your dose.
Consider the Method of Delivery: Oral supplements, IV therapy, and even intranasal sprays each have distinct absorption rates and bioavailability. Understanding how each method works can help you select the most convenient and effective option.
Review the Research: Staying informed about the latest studies on NAD+ can help you understand both its benefits and any potential side effects. Although most evidence points to a favorable safety profile, continual research is enhancing our understanding of its long-term effects.
Set Realistic Expectations: While many users report improved energy and cognitive function, NAD+ is not a cure-all. It should ideally be a part of a broader approach to health that includes proper diet, exercise, and stress management.
A growing number of clinics and wellness centers are now offering NAD+ IV therapy as part of their anti-aging and recovery programs. Patients frequently share testimonials about feeling revitalized, more energetic, and having clearer mental focus following treatments. While gastrointestinal discomfort is not uncommon, it is usually mild and temporary.
Many users have noted that any instances of diarrhea or other digestive disturbances typically occur when the dosage is too high for their system or if they are new to NAD+ supplements. By following dosing guidelines, these issues can usually be avoided. Additionally, clinical settings provide the advantage of professional monitoring, so any adverse effects can be quickly addressed.
It is important to remember that each person’s body chemistry and digestive health are unique. What works well for one person may not work as effectively for another. In clinical practice, patient feedback plays a crucial role in adjusting treatment protocols to maximize benefits while minimizing side effects.
