 Another important aspect of aging is the increased risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. Additionally, cognitive decline is another common problem. Memory loss, difficulty concentrating, and reduced mental agility can affect our daily lives.

 Many older adults also experience feelings of loneliness, depression, or anxiety, especially if they are facing health problems or have lost a loved one. In this situation, it is important to seek emotional support from family, friends, and even professionals.

 While we can't stop the aging process, there are ways we can slow it down and maintain a youthful appearance for longer. Anti-aging supplements are one good option.

Nicotinamide Adenine Dinucleotide (NAD+) and Aging

 NAD+ is an important coenzyme found in all living cells. Its main function is to promote cellular metabolism by aiding electron transfer in numerous biological processes such as energy production. However, as we age, NAD+ levels in our bodies naturally decline. Some studies suggest that declining NAD+ levels may be a contributing factor to the aging process.

 One of the most significant breakthroughs in NAD+ research was the discovery of the NAD+ precursor molecule called nicotinamide riboside (NR).  NR is a form of vitamin B3 that is converted into NAD+ within our cells. Multiple animal studies have shown promising results, suggesting that NR supplementation can increase NAD+ levels and potentially reverse age-related decline.

 Many age-related diseases, such as neurodegenerative diseases and metabolic dysfunction, are associated with impaired mitochondrial function. Mitochondria are the powerhouses of our cells, responsible for producing energy.  NAD+ plays a vital role in maintaining optimal mitochondrial function. By protecting mitochondrial health, NAD+ has the potential to reduce the risk of age-related diseases and extend lifespan. 

Nicotinamide Adenine Dinucleotide (NAD+) and Aging

 In addition, NAD+ is involved in the activity of sirtuins, a family of proteins associated with longevity.  Sirtuins regulate a variety of biological processes, including DNA repair, cellular stress responses, and inflammation.  NAD+ is essential for Sirtuin function, serving as a coenzyme that activates its enzymatic activity. By supplementing NAD+ and enhancing Sirtuin function, we may be able to delay aging and promote health and longevity.

 Numerous studies have shown that NAD+ supplementation has positive effects in animal models. For example, one study in mice showed that supplementing with NR improved muscle function and endurance. Other studies have shown that NR supplementation can enhance metabolic function in aged mice, making it similar to that of young mice. These findings suggest that NAD+ supplementation may have similar effects in humans, although further research is needed.

Nicotinamide Riboside: A NAD+ Precursor


 Nicotinamide riboside (also known as niagen) is another form of niacin (also known as vitamin B3) and is found naturally in small amounts in milk and other foods. It can be converted into NAD+ within cells. As a precursor, NR is easily absorbed and transported into cells, where it is converted into NAD+ through a series of enzymatic reactions.

 NR supplementation studies in both animal and human studies have shown promising results. In mice, NR supplementation was found to increase NAD+ levels in various tissues and improve metabolic and mitochondrial function.

 NAD+ is involved in a variety of cellular processes that decline with age, including DNA repair, energy production, and regulation of gene expression. It is hypothesized that replenishing NAD+ levels with NR could restore cellular function, thereby improving health and extending lifespan.

 Additionally, in a study of overweight and obese men, NR supplementation increased NAD+ levels, thereby improving insulin sensitivity and mitochondrial function. These findings suggest that NR supplementation may have potential applications in addressing metabolic diseases such as type 2 diabetes and obesity.

What is the best source of Nicotinamide Riboside


 1. Natural food sources of nicotinamide riboside

 One potential source of NR is dairy products. Some studies have shown that dairy products contain trace amounts of NR, especially milk fortified with NR. However, the NR content in these products is relatively low and obtaining sufficient amounts through dietary intake alone may be challenging.

 In addition to dietary sources, NR supplements are available in capsule or powder form. These supplements are often derived from natural sources such as yeast or bacterial fermentation. Yeast-derived NR is generally considered a reliable and sustainable source because it can be produced in large quantities without relying on animal sources. Bacterially produced NR is another option, often obtained from specific strains of bacteria that naturally produce NR.
