Sniffing mouse
Researchers publishing in Aging Cell have elucidated a relationship between aging, the loss of smell, and NAD+ in a mouse model. Olfactory ability declines with age Roughly half of people over the age of 65 experience a decreased ability to smell [1], and research has shown that it is an early biomarker for neurodegenerative diseases,...
Arm muscle
Scientists have shown that long-term treatment with a popular NAD+ precursor can raise NAD+ levels in blood and muscle and increase mitochondria content and function [1]. Twin-based design NAD+ is an important coenzyme that performs multiple functions, including mitochondrial energy production. NAD+ levels decrease with aging, which has been shown to underlie other age-related diseases....
Intestinal molecules
Scientists have shown that the NAD+ precursor nicotinamide riboside (NR) alleviates symptoms of leaky gut caused by ethanol consumption in mice by improving mitochondrial function [1]. What is Nicotinamide Riboside? Benefits and Side EffectsNicotinamide riboside (NR) is a B3 vitamin. Nicotinamide riboside gets converted into nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for life.Read MoreCategory:...
Dividing cancer
A paper published in the journal Biosensors and Bioelectronics has caused a stir in the longevity community by showing that nicotinamide riboside (NR), a precursor to NAD+, makes tumors more aggressive in a mouse model [1]. Using a novel diagnostic tool In this new paper, the researchers employed a well-known technique called bioluminescence imaging [2]...
Albino mouse
In a preprint published in bioRxiv, scientists have shown that long-term supplementation of nicotinamide riboside (NR), a NAD+ precursor, alleviates the progression of age-related hearing loss in a mouse model [1]. An overlooked hearing impairment Globally, age-related hearing loss (ARHL) is the most common sensory deficit of older people. Moreover, it is associated with several...
Two running mice
Scientists from Mayo Clinic have significantly extended lifespan in male mice by inhibiting the enzyme CD38, which lowers NAD levels [1]. The age-related decline of nicotinamide dinucleotide (NAD) has been associated with various metabolic abnormalities, age-related diseases, and fitness loss. What is Nicotinamide Adenine Dinucleotide?Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living...
