Strengths of Mirai Lab's
NMN supplements

As pioneer of bio-ventures,
we were the first in engage in NMN research,
and provide NMN products with a level of safety
and quality unmatched by any other company.

5 reasons to choose Mirai Lab


The only NMN products recognized by
the world-leading authority on NMN research,
Professor Shin-ichiro Imai.

Professor Shin-ichiro Imai, who broke new ground with his research on NMN, blows the whistle on the pandemonium of NMN capsules available on the market at present, and Mirai Lab’s Pure Series are the very products he can rely on. Mirai Lab's NMN Pure series boasts absolute purity with the approval of a leading expert. This NMN does not contain impurities or forms of NMN not produced naturally in our bodies.


We were the first in commercializing NMN
and we are the only company in Japan
having a research facility dedicated to NMN.

Commercialization focused on research on NMN, which is rapidly making the medical industry progress. We established our original supplement brand Mirai Lab and started making sales. Many NMN companies cite scientific papers published by anti-aging researchers or request external inspections from food analysis centers, but do not perform analysis using their own laboratories. Mirailab Bioscience is the only company in Japan that owns an in-house NMN research laboratory.


We conducted the world's first safety test on humans
Academia-quality NMN
used in cutting-edge clinical research

Mirai Lab's NMN was the first in the world to be used in a safety test on humans (*). In addition to demonstrating its safety, we confirmed the expression of the sirtuin genes, an increase in melatonin and other growth hormones in a long-term (24-week) administration clinical study at Hiroshima University School of Medicine. These achievements and its purity are highly considered, and our NMN products were selected as a test food to be used in a new clinical research at the University of Washington, School of Medicine, led by Professor Shin-ichiro Imai, an authority on NMN.

Our NMN has an absolute purity of 99.8% (1), according to a fair and transparent "absolute measurement method."
By "impurity" we mean a substance that's harmless to humans

97.2 92.0
Company B
98.3 99.0

The absolute measurement method quantifies what percentage of all substances detected in the sample is NMN, and indicates the purity with reference to NMN. On the other hand, the relative measurement method shows the relative value with reference to a "standard NMN" which is considered 100% pure. Surprisingly, the "standard NMN" in this second method can be supplied by the manufacturer itself, and its purity is not disclosed. Mirai Lab's NMN achieves an absolute purity of 99.8% (1), and when compared with other companies' products as shown below, the purity of Mirai Lab's NMN exceeds 100% in relative purity. This explains well by itself the overwhelming purity of Mirai Lab's products.

Purity of NMN samples by relative method

Differences in measuring purity

There are two different measuring methods: the absolute method and the relative method.
We employ the absolute method, which shows objectively how much is NMN, from all the substances found in a sample.

By relative method,
the purity of our NMN rises to 105%

(Purity as indicated by other companies)


Also, according to another analysis that determines the identity of the impurities found in the first test, the only impurity detected in our NMN is nicotinamide, a substance humans can ingest with total safety.

Please note that there are products from other brands available on the market that claim to contain high-purity NMN, while they may actually contain low-quality NMN whose safety has not been confirmed.

The effects of α-NMN in our bodies is unknown.
We only give you full β-NMN, the NMN your body needs.

NMN exists with two different molecular structures: α-NMN and β-NMN.
The NMN that we need is β-NMN, which is naturally generated in our bodies.
The other NMN, α-NMN, is something we don’t need and something not produced in us.
Mirai Lab is offers you NMN supplements with the only NMN you should care about: β-NMN.

According to various research institutes, the purity of our NMN is 99% or higher, and it has also been confirmed that it is highly safe for both humans and rodents. Only one other company in the world is offering such high-purity NMN nutraceuticals (as of April 2022).

For more information, please see Strong points of Mirai Lab's supplements.

What are the risks related to optical isomers?

For your safety and peace of mind, Mirai Lab's products do not contain any α-NMN at all. Our NMN is manufactured accoding to a special, precise method so that the result is exclusively full β-NMN.
For more information,please see Mirai Lab's NMN substance

What's the β-NMN that you use?

There are two types of NMN, α-NMN and β-NMN, which have different molecular structures.

The molecules α-NMN and β-NMN are called optical isomers because they have the same type and number of atoms, but the connections beetween them point at different directions.
The NMN we need by nature is β-NMN.
β-NMN is produced by the human body, while unnecessary α-NMN is not.
Many companies manufacture NMN following a cheap process of chemical synthesis with the only goal of reducing costs. When they do that, the possibility of ending up with a mixture of α-NMN and β-NMN is very high. Please note that β-NMN, without a trace of α-NMN, can only be produced through a very precise manufacturing process.
Mirai Lab's NMN supplement is a high quality product containing only β-NMN.
For more information, please see Mirai Lab's NMN substance.
