In summary, while NMN supplementation is an exciting area of research with potential health benefits, especially related to aging and metabolic health, it is essential to approach it with caution. Ongoing research and clinical trials will continue to inform safer usage guidelines and help identify the full spectrum of NMN's effects in humans. | In summary, while NMN supplementation is an exciting area of research with potential health benefits, especially related to aging and metabolic health, it is essential to approach it with caution.

=== | === Side Effects === | ||
Overall, there have been no serious side effects in humans clinical trials that have been due to the use of NMN. When taken at higher doses than intended, you could be facing side effects such as nausea, diarrhea, indigestion, and stomach discomfort. However, these are common side effects of supplements when taken in amounts that are too high.<ref>https://www.dremilnutrition.com/post/will-i-get-side-effects-from-my-nmn-intake#:~:text=Potential%20NMN%20Side%20Effects%20%2B%20Other%20Safety%20Concerns&text=When%20taken%20at%20higher%20doses,amounts%20that%20are%20too%20high.</ref> | |||

There is a theoretical concern that consuming NMN could deplete [[Methyl Donors|methyl groups]] in the body and might lead to a [[Methyl Donor Deficiency]] associated with symptoms such as low energy and tiredness. NMN is converted to NAD+ in the body, which can then be broken down into nicotinamide. Nicotinamide is then methylated by the liver to form N1-methylnicotinamide, which is excreted in the urine. This methylation process consumes a methyl group from [[S-adenosylmethionine (SAMe)]], the primary methyl donor in the body. | There is a theoretical concern that consuming NMN could deplete [[Methyl Donors|methyl groups]] in the body and might lead to a [[Methyl Donor Deficiency]] associated with symptoms such as low energy and tiredness.
