It is commonly marketed as an anti-aging product. It is essential for energy production and DNA repair. Other factors that make this coenzyme so important for healthy aging include its effects on sirtuin “anti-aging” proteins, mitochondrial activity, and involvement in regulating oxidative stress (a cause of many chronic diseases) and circadian rhythms (our “internal clocks”). This type of treatment may be used to manage symptoms of Parkinson’s disease, dementia or depression, for example. Niacin is an essential B-vitamin. As mitochondria lose some of their power, this seems to contribute to diseases and symptoms tied to aging, including heart failure, cognitive decline/neurodegeneration and fatigue.

According to Elysium — a company that sells NAD supplements and is run by “a team of scientists, innovators, and creatives” — “NAD+ has two general sets of reactions in the human body: helping to turn nutrients into energy as a key player in metabolism, and working as a helper molecule for proteins that regulate other biological activity.”. Nicotinamide riboside, or niagen, is an alternative form of vitamin B3, also called niacin. There is some comprehensive evidence that nicotinamide riboside supplements can increase NAD levels by about 2.7 times baseline levels [5]. Low NAD+ levels have been linked to health concerns like aging and chronic illnesses, such as diabetes, heart disease, Alzheimer’s disease and vision loss (1). Within brain cells, NAD+ helps control the production of PGC-1-alpha, a protein that appears to help protect cells against oxidative stress and impaired mitochondrial function (15). The results with 1-3 Mg/Kg by IP is extremely promising, as we note that sublingual delivery can be even more effective than IP delivery.
