Actually, human health depends on the ways the body can manufacture and then use energy.
The cells’ ability to produce energy can gradually decrease with age and the energy production loss may cause some typical signs of aging such as gradual weight gain, loss of insulin sensitivity, and a decrease in physical activity.
With age, the body may lose its ability to make nicotinamide adenine dinucleotide (NAD), which is a main factor for energy production. Experts showed the decreased levels of NAD in numerous tissues as mice age. Besides, previous research also revealed that NAD is not efficient when researchers gave it directly to mice, so they sought for an indirect way to increase the levels.
By giving NMN to mice, it has slowed down the decrease in aging mice and older mice had the metabolism and energy levels of younger mice. When human skin cells depend on the same energy production, hope that this process will be translated into a great way to help people keep healthy when they age. A new study showed that adding NMN to drinking water and then giving this water to mice makes this substance appear in their bloodstream in fewer than 3 minutes. Also, NMN found in the blood quickly can convert into NAD in lots of skin tissues.
The NMN may have no effect in younger mice as they were producing their own NMN. Nonetheless, many effects seen in older mice were in skeletal muscle, liver function, bone density, eye health, improved insulin sensitivity, immune function, less weight gain, and higher level of physical activity.
Experts also said that they searched about potential risks of cancer growth due to the intake of NMN and did not see any differences in cancer risks. NMN for humans to consume is not available commercially. Nonetheless, NMN is found in some natural foods such as broccoli, avocado, cabbage, cucumber as well as edamame beans.
