Ⅰ The purity
For NMN products, one of the important evaluation criteria is purity. Purity refers to the ratio of no other components in NMN. There are 50%, 90%, 95%, 99% and above purity on the market. The higher the purity, the better the absorption. For every 0.1% increase, the absorption rate will increase by 2-5 times. Therefore, it is safer to buy products with a purity greater than 99.9%, and there are almost no other impurities.
The purity of NMN can usually be obtained from product instructions or official websites. In addition, you can also consult the customer service of the manufacturer to obtain the most accurate information. If the manufacturer is unwilling to disclose the purity level, or cannot provide legal proof, then do not buy this product.
Ⅱ The content
When choosing NMN, you need to pay attention to its content. In different NMN products, the content of NMN is different. Some products contain very low NMN content, which not only has poor absorption effect, but may also cause other hazards.
The higher the content within a certain range, the better the effect. Current human trials have confirmed that a daily intake of 500 mg is the highest safe dose for the human body.
Ⅲ The place of origin
At present, Japan recognizes NMN as a legal dietary supplement, and some regions do not have relevant certification procedures for NMN, so the effect and quality of products produced in these regions are difficult to guarantee, and there may be risks.
For example, NMN products imported from the United States had to be produced in factories certified by the U.S. FDA (Food and Drug Administration) and strictly followed GMP standards to ensure the quality and safety of NMN products.
Ⅳ The price
Attention should be paid to NMN products that are too cheap. Some unscrupulous merchants will use α-NMN produced by chemical processes and have no biological activity to pretend to be β-NMN (β-Nicotinamide mononucleotide, enzymatically purified, with biological activity). Counterfeit NMN is usually cheap and has no effect on the human body. When purchasing, be sure that the main ingredient marked is β-NMN, and don't be deceived.
Ⅴ The preparation technology
When purchasing NMN products, another important factor is to look at the preparation technology. Different preparation technologies can affect the effect of NMN. Many NMN products are compounded with different ingredients, such as coenzyme Q10, probiotics, ginsenosides, resveratrol, etc. It is necessary to pay attention to whether the effect of NMN can be enhanced after compounding, and whether the compound ingredients themselves have outstanding effects.
NMN from APPCHEM Co. is made from specific raw materials through biological enzyme catalysis and other processes. It has the effects of skin protection, moisturization, anti-oxidation, and anti-aging, and has great application value in the field of cosmetics.
