Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are both precursors to nicotinamide adenine dinucleotide (NAD+), a coenzyme that plays important roles in energy production, DNA repair, and other cellular processes. The primary difference is that NR is a form of Vitamin B3 (Niacin), while NMN is a type of nucleotide.  NMN vs. NR NMN is converted into NAD+ directly by enzymes in the body, while NR needs to go through an additional step in the body in order to be converted into NAD+.  NR is converted into NAD+ in the body and is used to support the production of NAD+ . It is used in therapies for aging, weight loss, and cognitive decline. NMN is also a precursor to NAD+ and is used to support the production of NAD+ . NMN is a type of nucleotide, which are the building blocks of DNA and RNA, NMN is found in small amoun

Strokes can be divided into hemorrhagic stroke and ischemic strokes, and approximately 80% of them are ischemic brain injury. Ischemic strokes are sometimes referred to as "brain attacks" (instead of "heart attacks") because they typically occur when a blood clot blocks an artery or blood vessel, cutting off blood flow to your brain, as opposed to your heart. 1 As a result, brain cells die and neurological damage can occur. Without proper and timely treatment, a stroke can be lethal. According to statistics published in 2020, 2  an estimated 795,000 strokes occur each year in the U.S., and in 2017, 146,383 Americans died as a result. However, new research in 2022 shows an 11% increase in new cases of stroke that cause brain bleeding, or intracerebral hemorrhage stroke, and at a faster rate in younger to middle-age people. 3 Stroke is also a leading cause of long-term disability in the U.S. 4  Worldwide, stroke is the second
