Since ancient times, humans have always dreamed of having smooth, supple skin, being quick-witted and youthful. However, aging comes with a deterioration in physical appearance and health, along with many diseases such as cardiovascular disease, diabetes, and neurological degeneration such as Alzheimer’s and Parkinson’s, and cancer. Today, with the remarkable progress of science, reversing aging is no longer just a thing of science fiction movies.
Nicotinamide Riboside (NR), a form of vitamin B3, has been the subject of various scientific studies exploring its potential anti-aging effects through its role as a precursor to Nicotinamide Adenine Dinucleotide (NAD+), a molecule essential for cellular metabolism and repair. NR has been shown to increase NAD+ production significantly.
As we age, our NAD+ levels naturally decline, contributing to fatigue, cellular damage, and signs of aging. Supplementing with NR helps boost NAD+ levels, restoring cellular energy and slowing down age-related cellular decline. A study published in Nature Communications demonstrated that chronic NR supplementation effectively stimulates NAD+ metabolism in healthy middle-aged and older adults, indicating its potential to counteract age-related NAD+ decline.
From a holistic point of view, it is worth combining NR with other complementary ingredients like resveratrol, which often offer enhanced benefits. Fuciodan and sea buckthorn proanthocyanidins promote stem cell mobilization, thus supporting faster restoration and effective maintenance of the body’s functions – aiding NR’s anti-aging properties.

As we age, our skin undergoes several changes. One of the most noticeable changes is the disturbance in skin pigmentation, which causes age spots or hyperpigmentation. Pigmentation is controlled by melanocytes, specialized cells that produce the pigment melanin. Melanin protects the skin from the damaging effects of ultraviolet (UV) radiation, which is one of the leading causes of skin aging.
However, with age, the number of melanocytes in the skin decreases, and the remaining melanocytes become less effective at producing melanin. This can lead to uneven pigmentation and the formation of age spots. Additionally, UV exposure can cause melanocytes to cluster together and produce too much melanin, resulting in dark patches on the skin.
NR can play a significant role in anti-aging therapy, particularly in facial skin treatments. By increasing NAD⁺ levels, NR could help reduce the incidence of aging signs in the skin.
Studies have shown that NR can inhibit melanin production, leading to reduced hyperpigmentation. This suggests its potential as a skin spot-lightening ingredient, offering a new approach to managing skin discoloration.
NAD⁺, which NR helps to replenish, plays a pivotal role in cellular metabolism and is a co-substrate for enzymes that are key in pathways modifying aging. By restoring NAD⁺ levels, NR may support cellular repair mechanisms and protect against age-related cellular damage.
Boosting NAD+ levels with supplements like NR can promote skin cell health during aging.
If you want to preserve your beauty and youthful glow, not just on the surface, but from the cellular level, NR can be one of your most powerful allies in this natural, scientifically backed journey.

Our blood vessels transport vital nutrients to all our cells, and as we age, they become more rigid and susceptible to blockages, which can lead to heart attacks or strokes.
A clinical trial involving patients with heart failure with reduced ejection fraction demonstrated that NR supplementation (1,000 mg twice daily) was safe and effectively doubled whole blood NAD⁺ levels. This increase correlated with enhanced mitochondrial respiration in peripheral blood mononuclear cells and reduced expression of inflammatory markers, suggesting improved cardiac function.

Participants who took NR for six months showed a significant improvement in their six-minute walking distance compared to those who received a placebo, suggesting enhanced vascular function and exercise capacity.
In mouse models of dilated cardiomyopathy, NR supplementation attenuated the progression of heart failure. The treated mice exhibited improved cardiac function, highlighting NR’s potential in preserving heart health under stress conditions.
In vascular health, other ingredients can further support the effect of NR, thus worth combining. Vascular wall stem cells and cardiac stem cells could be activated by fucoidan (scientifically known as endothelial and cardiac progenitors). Their respective percentages climbed by 70% and 25%.

As women age, they experience a decline in oocyte (egg) quality, which can lead to fertility problems. However, Nicotinamide Riboside (NR), a precursor to NAD⁺, has been studied for its potential effects on reproductive health, particularly in the context of aging.
Oocyte Quality: Research indicates that NR supplementation can improve the quality of post-ovulatory oocytes. A study found that NR treatment decreased reactive oxygen species (ROS) levels, reduced DNA damage, and lowered apoptosis rates in these oocytes, thereby enhancing early embryonic development potential.
Fertility Restoration: In aged female mice, NR supplementation has been shown to rejuvenate oocyte quality, leading to restored fertility. This improvement is associated with increased NAD⁺ levels, which play a crucial role in cellular energy metabolism and DNA repair.
Oocyte quality and health can be greatly supported also by Coenzyme Q10.
Effects on Male Reproduction and Sperm Quality: As men get older, their ability to produce sperm, known as spermatogenesis, declines. Research conducted on mice suggests that the reduction in sperm production occurs due to the depletion of NAD+ levels that accompany aging. This has led some experts to suggest that NR supplementation may improve low sperm counts in aging men by restoring NAD+ levels.

As adults get older, the immune system declines, and people get ill more easily.
Nicotinamide Riboside (NR), a precursor to Nicotinamide Adenine Dinucleotide (NAD⁺), plays a significant role in modulating immune function. NAD⁺ is essential for various cellular processes, including energy metabolism, DNA repair, and regulation of immune responses.
NR supplementation has been shown to bolster immune cell function. A systematic review of preclinical studies found that NR can enhance the activity of immune cells and reduce the expression of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6. This suggests that NR may help modulate inflammation and support a balanced immune response.
NR contributes to the regulation of inflammation by replenishing NAD⁺ levels, which are crucial for the activity of sirtuins—proteins involved in inflammatory control. By restoring NAD⁺, NR may help rebalance immune responses and reduce excessive inflammation.
Research indicates that targeting NAD⁺ metabolism through NR supplementation could be beneficial in modulating autoimmunity and inflammatory diseases. By influencing immune cell metabolism, NR may offer therapeutic potential in these conditions.

NR, or nicotinamide mononucleotide, is a molecule that has gained interest in anti-aging research due to its potential ability to boost levels of NAD+. This coenzyme plays a critical role in cellular metabolism and energy production. NAD+ levels decline as we age, which is believed to contribute to many age-related health problems. Supplementing with NR increases NAD+ levels and promotes cellular health, potentially slowing the aging process.
One way NR is thought to work is by activating the Sirtuin Genes, a family of enzymes that play a role in regulating cellular function, including DNA repair, inflammation, and metabolism. Sirtuins have been linked to increased lifespan in several animal studies. According to the results of clinical trials of human studies, boosting sirtuin activity through NR supplementation could lead to similar benefits in humans.
While the research on NR and anti-aging is still in its early stages, there is growing evidence to suggest that NR may have a range of health benefits beyond just anti-aging, including improved metabolic function, increased exercise endurance, and protection against age-related diseases.
