As of my last knowledge update in January 2022, there is no substantial evidence to suggest that Nicotinamide Mononucleotide (NMN) is toxic to the liver when used at recommended doses. NMN is a naturally occurring molecule in the body and is generally considered safe when taken as a dietary supplement. However, research on the long-term effects of NMN supplementation is still relatively limited.
It's essential to note that the safety and potential side effects of any supplement can vary from person to person. If you have concerns about the impact of NMN on your liver or any other aspect of your health, it is advisable to consult with a healthcare professional before starting NMN supplementation. They can provide personalized guidance based on your health history and individual needs.
Additionally, it's crucial to purchase NMN supplements from reputable sources and follow the recommended dosage instructions provided on the product label. Avoid taking excessive amounts of any supplement, as doing so can increase the risk of adverse effects. Always prioritize your safety and consult with a healthcare provider when making decisions about dietary supplements.
