A fundamental molecule present in all the cells of our body, NAD+ (Nicotinamide Adenine Dinucleotide) actively participates in many biological processes essential for our survival. To understand its role, it is important to know its structure as a dinucleotide , that is, it is composed of two parts: nicotinamide and adenine , connected by a phosphate group (chemical group containing a phosphorus atom bonded to four oxygen atoms, playing a key role in biochemical reactions) .
NAD+ is essentially an oxidized form of NAD, while NADH is its reduced form. These two forms, NAD+ and NADH, function as a key electron transfer system in the chemical reactions of our cells. They are involved in energy production, regulation of metabolism, and act as coenzymes (molecules that help enzymes catalyze chemical reactions in cells) in many vital enzymatic reactions.
In other words, NAD+ and NADH play a central role in maintaining our health and vitality .
How is NAD+ produced in our body?
NAD+ is primarily produced in our bodies from vitamin B3 , also called niacin or nicotinamide . When we eat foods containing niacin, our body converts it into NAD+ through complex enzymatic reactions. This production of NAD+ is essential for maintaining our energy levels and supporting many vital biochemical reactions.
How is NAD+ linked to the aging process?
As we age, our NAD+ levels tend to decrease, which can contribute to a decrease in the efficiency of cellular processes and accelerated aging. That's why research is exploring the potential of NAD+ supplementation to slow aging and promote long-term health.
This is the case of a study published on May 15, 2017 entitled “Targeting NAD+ in Metabolic Disease: New Insights into an Old Molecule” ( 1 ) , which examines how NAD+ is involved in various processes related to metabolic health and aging. This study suggests that NAD+ may help fight cellular aging by activating enzymes called sirtuins . Sirtuins are important for several processes related to aging, such as the regulation of cellular energy production and the stress response. By increasing NAD+ levels, we can potentially improve the functioning of sirtuins and therefore slow certain aspects of cellular aging. However, there remain questions to explore in this area of research.
How to maintain or increase NAD+ levels in the body?
Natural approaches are possible to maintain or increase NAD+ levels in the body. This involves eating a balanced diet rich in nutrients such as tryptophan (the amino acid that helps produce serotonin) , niacin (vitamin B3) , and nicotinamide riboside (NR) from foods like chicken, fish, and green vegetables. Regular exercise and intermittent fasting can also support NAD+ biosynthesis.
However, taking food supplements offers a higher concentration of NAD+ precursors such as NR. Our products are specially designed to facilitate this approach. The capsules are a convenient solution for regular supplementation, with options for one-month or three-month use, tailored to your needs. Alternatively, our powder can be mixed with your favorite drink or food, providing flexibility in how you choose to incorporate it into your daily routine to optimally support your NAD+ levels.
Caution : Consult a healthcare professional before starting any dietary supplement.
Finally, NAD+ is a crucial molecule for our body, playing an essential role in metabolism and energy production. As we age, our NAD+ levels may decrease, but there are natural approaches, such as a balanced diet and exercise, to maintain them. Dietary supplements also offer a convenient option for increasing NAD+ levels effectively.
