Emerging Nutritional Supplements Help You Fight Aging! | What NMN is and Its Benefits

Do you have to take injections to effectively fight aging?! No need for injections, NMN is enough! In today’s society, people’s pursuit of longevity and health is becoming stronger. NMN (Nicotinamide Mononucleotide) as an emerging anti-aging product, has aroused great attention in the health field. This article will introduce the advantages of NMN and how it becomes the best choice to prolong youth.

What is NMN?

Nicotinamide Mononucleotide, abbreviated as NMN, is a substance naturally present in the human body, playing a vital role in energy metabolism. It is capable of being transformed by the body into another compound called NAD+ (Nicotinamide Adenine Dinucleotide), which is crucial for cellular survival and function during energy metabolism. NMN is found mainly in dairy products and pork, but it is challenging for our bodies to obtain sufficient NMN from these food sources alone. As we age, the levels of NMN in our bodies decline, leading many people to supplement NMN to improve their health conditions.

NMN, NAD+ and the Relationship to Anti-aging

NMN (Nicotinamide Mononucleotide) and NAD+ (Nicotinamide Adenine Dinucleotide) are both compounds that naturally occur in the human body and play an essential role in cellular metabolism and energy production.As we age, NAD+ levels in our bodies tend to decline, which is associated with a decrease in mitochondrial function, increased DNA damage, and many other factors that contribute to the aging process. This decline in NAD+ levels has been linked to numerous aging-related health conditions, such as cardiovascular disease, neurodegenerative diseases, and even cancer.

NMN is a precursor to NAD+. This means that our bodies can convert NMN into NAD+. Supplementing with NMN can therefore increase the levels of NAD+ in our bodies, potentially mitigating the aging-related decline in NAD+ levels.

How Can NMN Help Us?

Nicotinamide Mononucleotide (NMN), a naturally occurring chemical, is essential to cellular metabolism. It produces NAD+, a coenzyme needed for several metabolic activities. Here are some benefits of NMN:

  • Increasing NAD+: NAD+ levels decline with age, which may contribute to physiological indications of aging. NMN may increase NAD+ production, which may slow aging.
  • NAD+ boosts mitochondrial energy production. NMN supplementation can boost NAD+ levels and cell energy generation. NAD+ helps repair DNA and activate cell damage proteins. Thus, increasing NAD+ levels with NMN may help our bodies repair damaged cells, promoting health and lifespan.
  • Supporting Cognitive Function: NMN may improve brain function, especially in age-related cognitive decline. The compound’s energy generation, DNA repair, and cell survival may explain this.
  • NMN supplementation improves metabolic parameters including blood sugar management and cholesterol profiles in animals. However, additional study is needed.

Why Can’t We Directly Consume NAD+ Supplements?

NAD+ (Nicotinamide Adenine Dinucleotide) is essential to several metabolic pathways. It may seem rational to directly supplement with NAD+ to increase levels, however the body cannot absorb it.The major reasons we can’t directly absorb NAD+ supplements: NAD+ is a big molecule, making it difficult to absorb directly via the digestive system. Oral NAD+ would likely be broken down into its constituent parts during digestion, preventing absorption. NAD+ would still confront problems after digestion. Getting undamaged NAD+ molecules into cells is difficult. The cell membrane selectively blocks big molecules like NAD+. NMN and NR, precursors of NAD+, are smaller and more absorbable. They efficiently penetrate cells and convert to NAD+, making them potentially more powerful NAD+ boosters.

NMN Buying Guide

Understand the Main Ingredients of NMN Products

Currently, NMN products on the market are usually sold in the form of capsules, powders or oral liquids, and there are many brands to choose from. These products contain NMN as the main ingredient, and depending on different brands and products, may also contain other ingredients, such as vitamins C, E, and B vitamins, etc., to supplement other nutrients your body needs at once. However, when choosing NMN products, we need to pay attention to the following points:

Quality and purity: Choose a reliable, verified brand to ensure the quality and purity of the product.

Dosage: Understand the recommended dosage of each NMN product and use it reasonably according to your own needs.

Formula: If you have specific needs, such as wanting to improve cognitive function or cardiovascular health, you can choose products that contain related ingredients to maximize the effect.

Understand the Purity and Content of NMN Products

NMN is a precursor of vitamin B3 and an important anti-aging substance. The purity and content of NMN products are two key factors in determining their quality.

Purity refers to the proportion of NMN molecules in the product. Generally, the higher the purity, the better the quality of the product. High-quality NMN products can reach a purity of 99% or more, while low-quality products may contain other impurities, which may be harmful to human health.

Content refers to the concentration of NMN molecules in the product, usually in milligrams (mg) or grams (g). The higher the content, the more effective ingredients in each dosage, meaning its effects may be better, but the price may also be higher.

In order to use safe and reliable NMN products, it is recommended to choose high-purity and high-content products from reliable manufacturers, and it is also recommended to consult a doctor to understand your needs.

How to choose a certified safe NMN supplement?

For the safe and effective intake of dietary supplements, the safety of the product is naturally the top priority. When choosing a brand with safety certification, you should first consider brands that have obtained FDA registration, comply with GMP standards in their production process, and have safety assessment reports. Secondly, check the source of raw materials, preferably choosing NMN extracted from natural plants or synthesized NMN, and avoid NMN produced by genetic engineering. At the same time, you should confirm whether the product contains residual agricultural chemicals, and select NMN products without residues of pesticides, fungicides, and other pesticides. Lastly, consider the reputation of different brands, learning from the experiences of others to choose the product most suitable for you.

What needs to be noted about the technology used in NMN product manufacturing?

Even though the raw materials are the same, the method of product synthesis will directly affect the effectiveness of the product. Among the many synthesis technologies, NMN products made using enzyme synthesis technology are considered the best. The latest research shows that NMN supplements produced using enzyme synthesis technology have several main advantages:

Higher purity: The purity of enzymatically synthesized NMN can reach over 98%, promoting clearer and more definite biological effects.

Better bioefficacy: High-purity NMN is more easily absorbed and converted into NAD+ by the human body, thereby increasing NAD+ levels.

Safer raw material source: Enzymatic synthesis does not require plant extraction or genetic engineering technology, so there are no GMO and pesticide residue safety concerns.

High product stability: The conditions for enzymatic synthesis of NMN are mild, which helps maintain the chemical stability and biological activity of NMN, ensuring the effectiveness of the product.

Is it better to choose powder or capsules?

Currently, NMN supplements on the market are mainly available in powder or capsule form. Although each has its pros and cons, the choice depends on personal preference and needs. The detailed comparison is as follows:

  Advantages Disadvantages:
Powder Form: No Wastage – NMN in powder form is more easily absorbed by the body, achieving the best effects. 

It offers versatile ways of consumption – NMN powder can be mixed into drinks, or directly ingested without any water.

Users can adjust the dosage to ingest a larger amount depending on one’s needs.

Capsule Form: Convenient to carry and for travelling Efficacy rate is slightly lower – NMN in capsule form has a lower absorption efficiency than powder. Capsules can include ingredients that are not active and can be less bioavailable due to wastage.

Capsules can contain a mix of ingredients that are not useful and ingestion of extra ingredients.


Hence, if users value the efficacy of the product, it’s recommended to choose NMN products in powder form.
