What is NAD and why is it important?
NAD, or nicotinamide adenine dinucleotide, is a coenzyme found in every cell that plays a crucial role in energy production. NAD acts as a molecular "switch" that helps convert nutrients into energy in the mitochondria, the powerhouses of the cells. It exists in two main forms: NAD+ (oxidized) and NADH (reduced). NAD+ accepts electrons during metabolism and is converted to NADH, enabling cellular respiration and energy-generating processes.
Our NAD levels naturally decline with age. Research shows that NAD peaks in our twenties and can drop by up to 50 percent by the age of 50. This decline is linked to aging and reduced cellular function. This is why NAD supplements have become popular within the longevity movement and among biohackers who want to maximize their energy and lifespan.
What is NAD?
NAD is an abbreviation for nicotinamide adenine dinucleotide, a coenzyme that is essential for our cells to produce energy. It functions as an electron carrier in cellular respiration and is crucial for mitochondria to convert food into ATP, the body's energy currency.
There are three relevant forms:
- NAD+: The active, oxidized form
- NADH: The reduced form
- NAD: The collective name for both forms.
NAD+ can be compared to the fuel that keeps mitochondria working efficiently. Statistically, NAD levels are highest when we are young, but they gradually decrease with age. Low NAD levels have been linked to faster aging and impaired cellular health. Therefore, interest in NAD supplements has increased, especially among those who want to optimize energy and longevity.
NAD and the body's health
NAD affects several important processes in the body, including energy levels and metabolism. Without sufficient NAD, cells cannot efficiently produce energy, which can lead to fatigue and reduced physical performance. NAD is also crucial for DNA repair and protection against cell damage.
Studies have shown that increased NAD levels can contribute to better mental performance, memory, and cognitive health. One example is research where participants reported reduced fatigue and increased energy after supplementation. Statistics show that individuals with higher NAD levels often experience better physical endurance.
NAD has also been linked to a reduced risk of age-related diseases. For those who want to delve deeper into the scientific aspects, we recommend "Scientific Benefits of NAD Therapy," which describes several of NAD's effects on long-term health and aging. In summary, NAD supplements are an important piece of the puzzle for those striving for a long and healthy life.
Why do NAD levels drop?
The main cause of decreased NAD levels is natural aging. A steady decline is seen even after the age of 20. However, lifestyle factors also play a role, such as:
- Chronic stress
- Poor sleep quality
- Inadequate diet
- Smoking and heavy alcohol consumption
For example, smoking and alcohol have been shown to accelerate the loss of NAD in the body. Statistics show that NAD levels can decrease by up to 50 percent between the ages of 20 and 50. For some, NAD supplements may then be relevant, especially if one wants to counteract fatigue or improve recovery.
In addition to supplements, preventative measures are important: a healthy diet, regular exercise, and stress management help maintain the body's NAD levels. By understanding these factors, you can make more informed choices about your health and when NAD supplements might be the right option.
How do NAD supplements work?
Understanding how NAD supplements work is crucial if you want to maximize their effect on your energy, recovery, and cellular health. The 2025 market offers several different forms and combinations, and knowledge of the differences will help you choose the right one.
Types of NAD Supplements
There are several types of NAD supplements, the most common being NAD+, NMN (Nicotinamide Mononucleotide), and NR (Nicotinamide Riboside). All of these are precursors to NAD and can be converted in the body to raise NAD levels.
Bioavailability, which refers to how well the body absorbs the substance, varies between the different forms. Research shows that NMN and NR are the most studied and have a high absorption rate.
Here is a comparison of common forms:
