4 key features that are different between NR and NMN

Usually, we do not study cells for a living. You may already know about the NAD (Nicotinamide adenine dinucleotide) is sensitive for the human body, decreases with our increasing age. Let’s review a quick difference between the nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR):

  • NMN is not a vitamin while NR is.

NMN is not a part of vitamin B3. Also, there is no proof that it clinically increases NAD in the human body. Moreover, NMN molecules could never be considered as vitamin as it has phosphate particles in its molecules that affect it to enter the cells whereas NR can enter into the cells as it is the largest part of NAD.

  • NR makes NAD in just 2 steps while NMN requires 3 steps

NR can directly enter into the cells, so it requires only 2 steps to make it a NAD. Unlike NR, NMN requires 3 steps to create a NAD, NMN has to be converted into NR first then they can enter into the cells. After entering the cell, they convert into NMN again to make NAD. This process is long and inefficient.

  • NMN was taken by injection while NR can be taken orally

Another important difference is that although NMN is sold in the form of pills still study shows that they are preferred to be injected while NR is usually added in the food or water. Also, NR comes in a capsule form that is taken as a vitamin more.

  • NR reduces the NAD level up to 60% in human bodies while NMN does not

There is no evidence for NMN that shows if it affects the human body or not while in a recent study, it has been seen that NR taken 1000mg/day increases NAD in humans up to 60% in the adults


These are some differences that you should know between NR and NMN and which are more effective and efficient for the human body. There are fewer data records for NMN whereas more findings and positive data about NR. The differences tell which one is more effective.
