At what age should I start taking NMN?

NAD+ levels begin to exponentially deplete once you enter your 30s.

According to an Australian clinical trial, titled “Age-Associated Changes In Oxidative Stress and NAD+ Metabolism In Human Tissue,” the average NAD+ of a newborn baby is 8.54. The NAD+ average for age group is 30-50 is 2.74 and the age group 51-70 is 1.08.

Of course, lifestyle factors such as smoking, alcohol use and sleeping habits will also affect your NAD+ levels.

Why supplement with NMN but not NAD+?

The molecular size of NAD+ is large, which makes it difficult to pass through the body’s cell membrane. Fortunately, studies have shown that the smaller molecules of NMN can be absorbed by the body, which can then be converted into NAD+.

What does the NMN12000 on the package of Mitsuwa® Ocean Blue Pure NMN represent?

The 12000 in NMN12000 represents the total mg content in each Mitsuwa® Ocean Blue Pure NMN box. Each Ocean Blue Pure NMN capsule is equivalent to 200 mg of NMN.

Why NMN is better than NR

Both nicotinamide mononucletide (NMN) and nicotinamide riboside (NR) are precursors to nicotinamide adenine dinucleotide (NAD+). NAD+ is the essential molecule for metabolism, anti-aging and cell regeneration. NMN is the immediate precursor to NAD+, whereas NR requires conversion to NMN before converting to NAD+. As shown in recent clinical trials, NMN’s ability to immediately convert into NAD+ makes it more effective against aging when compared to NR.
