NMN supplements are primarily used for their potential anti-aging effects.

Last Modified: 03 May 2024

Jump to section:


Nicotinamide Mononucleotide (NMN) is a derivative of the B-vitamin niacin that functions as a dietary supplement. NMN is a precursor to NAD+, a crucial compound in energy production, DNA repair, and cell health. NMN is naturally found in several foods, including avocado, broccoli, and beef. NMN supplements are typically made synthetically in a lab. This dietary supplement is available under various brands, such as Tru Niagen and Elysium Basis. 

Global Name

Generic Names: Nicotinamide Mononucleotide (NMN)

Brand Names: Brand names may vary as NMN is sold by various supplement companies under different names. There is no single predominant brand name, as it is not a prescription drug but a dietary supplement. 



What is NMN used for?

NMN supplements are primarily used for their potential anti-ageing effects. Research suggests that NMN may: 

  • Improve energy metabolism 
  • Enhance DNA repair 
  • Support cognitive function 
  • Promote insulin sensitivity 
  • Support immune function

Please note that while preliminary research is promising, more studies in humans are needed to confirm these potential benefits. 

How Do You Use NMN? 

Dosage information is as follows: 

  • A common dosage range for NMN is 250-500mg per day, but the optimal dosage is not yet established due to limited research. 

NMN can be taken by: 

  • Adults 
  • Elderlies 

However, as the safety profile for children is not well-studied, NMN is not typically recommended for this group. 

Those who should not take NMN include: 

  • Individuals with a known allergy to NMN or any of its other ingredients. 
  • Pregnant or breastfeeding women, due to insufficient safety data. 

Warnings and precautions: 

  • Always consult with a healthcare provider before starting any new supplement, especially during pregnancy and lactation. 
  • NMN should be taken with caution in individuals with diabetes as it may affect blood sugar levels. 

As of now, no specific drug interactions have been identified, but research in this area is ongoing. 

Side Effects

While NMN is generally well-tolerated, potential side effects include mild nausea, stomach discomfort, and headaches. 

Pharmacist Tips

  • Store NMN in a cool, dry place, away from direct sunlight. 
  • Follow the instructions on the product label for best results.
  • NMN can be taken with or without food, but some people prefer to take it with a meal to help avoid potential stomach discomfort. 


Where is NMN available in Hong Kong?

NMN is an over-the-counter (OTC) medication that can be sold without a prescription. It is found in all chain drug stores, including Mannings and Watsons.


What is NMN supplement?

NMN has gained attention for its potential role in promoting cellular health and longevity, based on preclinical studies suggesting it may help mitigate age-related physiological decline. 

When to take NMN?

No specific age is universally recommended for starting NMN supplementation, as it is generally targeted towards adults concerned with ageing and age-related decline. Most interest in NMN supplementation begins in middle age or later when age-related cellular changes become more pronounced. 

What is NMN good for?

NMN is a precursor to NAD+ (nicotinamide adenine dinucleotide), a vital molecule in cellular energy and repair processes, and it is believed to have potential benefits in ageing, metabolism, and overall cellular health. However, while preclinical studies are promising, more research, especially in humans, is necessary to confirm these benefits.
