January 09, 2025 5 min read

Introduction

NAD⁺—or nicotinamide adenine dinucleotide—is a coenzyme found in every cell of your body. It plays an essential role in energy production, DNA repair, and metabolism. As we age, NAD⁺ levels naturally decrease, which has led many people to explore supplementation as a way to combat fatigue, support metabolic health, and even slow some age-associated declines.

One common question in the world of biohacking and wellness is: “How much NAD should I take?” In this blog post, we will break down what NAD⁺ is, explain the different forms of supplementation available, review current dosage guidelines based on scientific research, and discuss how to personalize your regimen safely.

What Is NAD⁺ and Why Is It Important?

NAD⁺ is an essential molecule that drives cellular processes by helping turn nutrients into energy. It is involved in redox reactions where it alternates between forms to assist enzymes that build and repair cells. In addition to energy metabolism, NAD⁺ also acts as a co-substrate for enzymes responsible for DNA repair and immune function.

As we age, our NAD⁺ production tends to decline, resulting in a decrease in cellular energy production and possibly contributing to the progression of age-related conditions such as neurodegeneration, metabolic syndrome, and even reduced exercise performance.

By supplementing with NAD⁺ boosters or precursors, many hope to restore levels to those more common in youth, which may promote overall health and vitality.

Different Forms of NAD⁺ Supplementation

There are several ways to boost NAD⁺ levels. The most common approaches involve taking precursor molecules that your body converts into NAD⁺. Some of these include:

Nicotinamide Riboside (NR):
NR is among the most widely studied precursors. It is known for its high bioavailability and ease of conversion. Research studies have tested daily doses between 250 mg and 1000 mg, with many trials finding that 500 mg per day appears to be effective for increasing NAD⁺ levels.
Nicotinamide Mononucleotide (NMN):
NMN is larger than NR and is another popular precursor for boosting NAD⁺. Studies have examined doses ranging from 250 mg up to 1200 mg per day. Although promising in animal studies, research in humans about NMN is still emerging; however, early results indicate that even lower doses might have beneficial outcomes.
Nicotinamide (NAM):
Also known as niacinamide, NAM is another precursor that can enhance NAD⁺ production. It is generally considered safe in moderate doses, though very high doses may lead to side effects. Unlike NR and NMN, NAM requires several conversion steps and may not be as efficient in boosting NAD⁺ directly.
Other Delivery Methods:
In addition to oral supplements, some clinics offer NAD⁺ via injections or IV therapy. These methods bypass the digestive process, theoretically delivering NAD⁺ or its precursors more directly into your bloodstream. Injections and IV methods are often used when a more rapid increase in NAD⁺ is desired.

How Much NAD⁺ Should You Take? Dosage Guidelines

Determining the “right” dosage for NAD⁺ supplementation largely depends on the form of precursor you choose, your specific goals, and your individual health status. Here’s a general breakdown:

Nicotinamide Riboside (NR):
Clinical trials typically use doses between 250 mg and 1000 mg per day. Many studies suggest that a dose of around 500 mg daily is both safe and effective for increasing circulating NAD⁺ levels.
Nicotinamide Mononucleotide (NMN):
NMN doses vary more widely—from 250 mg up to 1200 mg per day. Some human studies indicate that even at the lower end (250–600 mg daily), you can see a boost in blood NAD⁺ levels. However, higher doses may be more effective for some people, based on individual metabolic differences.
Nicotinamide (NAM):
Because NAM is metabolized differently, doses are typically kept moderate. Although higher doses can be used, many experts recommend starting with lower amounts to ensure tolerability. Daily doses under 900 mg are quite common and appear to be effective without significant side effects.
IV Injections/Drips:
When delivered directly through injections or IV therapy, the dosages cited in clinical settings range between 500 mg to 1500 mg per infusion for IV therapy. With injections, smaller, more frequent doses (like 100 mg per shot) are common, and protocols may involve a regimen spanning several days or weeks.

While these guidelines offer a starting point, it is crucial to understand that the optimal dose is individualized.

Factors to Consider When Determining Your Dosage

Several personal factors can affect how much NAD⁺ you should take. Here are some key considerations:

Age:
As NAD⁺ levels naturally decline with age, older individuals may require higher doses to see the same benefits as someone younger. This is why many studies on NAD⁺ supplementation have focused on middle-aged to older adults.
Lifestyle and Activity Level:
Regular physical activity, stress levels, dietary choices, and overall lifestyle may influence your body’s NAD⁺ needs. For example, those who exercise intensely or experience chronic stress might have different requirements than sedentary individuals.
Existing Health Conditions:
Conditions like metabolic syndrome, type 2 diabetes, or neurodegenerative diseases may alter NAD⁺ metabolism. People with these conditions should closely monitor dosages under the guidance of a healthcare provider.
Genetic Differences:
Everyone’s metabolism is different. Genetic variations can affect enzyme efficiency related to NAD⁺ synthesis and consumption. This means that some people might convert precursors more efficiently than others.
Supplement Form and Absorption:
The type of NAD⁺ precursor you use matters. For example, NR and NMN have different absorption and conversion rates. Additionally, the method of administration (oral supplement vs. IV or injection) can significantly impact how much NAD⁺ eventually reaches your cells.

Because of these factors, many experts recommend starting with a moderate dose and adjusting based on your body’s response. Many individuals track their progress through self-assessments, feedback on energy levels, or even periodic laboratory tests to measure intracellular NAD⁺ concentrations.

Timing and Frequency: When Should You Take Your NAD⁺ Supplement?

Apart from the dosage, timing and frequency of taking your NAD⁺ supplement can also play a role in its effectiveness:

Daily Consistency:
NAD⁺ precursors tend to work best when taken consistently. Daily supplementation helps maintain steady levels, ensuring that your cells have uninterrupted access to the coenzyme for energy production and repair.
Morning vs. Evening:
Many people prefer taking NAD⁺ supplements in the morning. The thought behind this is that increased NAD⁺ levels can help rev up your energy production throughout the day. However, if you find that you experience any stimulation or slight alertness, you might consider adjusting the timing according to your personal sleep patterns.
With or Without Food:
NAD⁺ supplements can generally be taken with or without food. Some individuals report that taking the supplement on an empty stomach increases absorption, while others might experience mild stomach discomfort. Experiment with timing and meals to determine what works best for you.
Alternate Dosing for IV or Injections:
If you are using IV or injection methods, follow the specific treatment schedules recommended by the provider. These sessions might be administered less frequently (for example, weekly or biweekly) after an initial intensive phase.

Safety and Precautions

NAD⁺ supplementation is generally considered safe within the dosing range used in clinical studies. However, there are a few precautions to keep in mind:

Monitor for Mild Side Effects:
Some users report side effects such as mild flushing, nausea, or headaches when starting supplementation. These symptoms often subside as your body adapts to the supplement.
Consult With Your Healthcare Provider:
It is always best to speak with a medical professional before starting any new supplement regimen, especially if you have pre-existing medical conditions or are taking medications that could interact with NAD⁺ boosters.
Quality of the Supplement:
Since dietary supplements are not regulated as strictly as pharmaceutical drugs, ensure you purchase NAD⁺ booster products from reputable companies that provide transparent testing and quality assurances.
Adjusting the Dosage:
If you’re new to NAD⁺ supplementation, start with a lower dose and gradually increase it. This titration process helps your body adjust and minimizes potential side effects. Some people choose to use laboratory testing (like intracellular NAD⁺ tests) to help tailor the right dosage for their needs.
