nr or nmn, also known as nicotinamide riboside, is the biosynthetic precursor of NAD+. It’s an incredibly important molecule, and it’s been shown to significantly increase NAD+ levels in the blood. NAD+ is a powerful antioxidant that protects against oxidative damage and can help improve insulin sensitivity, mitochondrial function, and more. The molecule can also improve a wide array of symptoms associated with aging and disease, including increased physical performance (up to 80 percent in some studies), improved vision, increased bone density, fewer migraines, decreased cholesterol, less arterial stiffness, more energy and endurance, better weight loss, and more. It’s even been shown to improve mitochondrial health in a variety of diseases like Friedreich’s ataxia, and it’s an effective treatment for a range of metabolic disorders.
Does NMN reverse GREY hair?
Nmn is very similar to NR, but it has one extra phosphate group which makes it larger than NR. This has led to a longstanding belief that it needs to be broken down into NR first before entering cells, but a new study in mice suggests this is not true. It turns out some tissues express a transporter that allows NMN to enter cells intact, bypassing the need to convert it to NR.
This means NMN might be more efficient than NR when it comes to increasing NAD+ levels. However, we need head-to-head comparison studies to be sure. Until then, many researchers recommend taking nmn, especially given the fact that it’s easier to find.
