What is NMN?

NMN is short for nicotinamide mononucleotide. It is a naturally occurring molecule present in the cell of every living organism.  
The cell is said to be the fundamental unit of life. Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work. However, cells rely on certain chemicals before they can convert nutrients into energy for the body. This is where NMN comes in. 

What does NMN do?

The main role of NMN is that it functions as a key component to increase NAD+ (Nicotinamide Adenine Dinucleotide) levels in cells. NAD+ is the next component in the chain process that help cells to perform their function. Research has discovered that having high levels of NAD+ helps the body increase metabolism, repair DNA, and protect against age-related diseases.     
Today, NMN supplements are sold and marketed as NAD+ booster. This is because they can restore nicotinamide adenine dinucleotide (NAD) levels in the body effectively. For us to understand NMN perfectly, we also must learn about NAD+.

What is NAD+?

NAD+ is an essential coenzyme found in all living cells. NAD+ is essential to life and cellular functions. It helps cells to generate energy by stimulating metabolism. NAD+ also promotes DNA repair and facilitates important chemical processes such as glycolysis and sirtuin secretion inside our cells. NAD+ also acts as a regulator. This coenzyme can decrease or increase enzyme activity, gene expression, and cell signalling. 
Unfortunately, NAD+ levels decrease gradually with age. When we are 50 years old, most of our NAD+ levels are about half of what they were when we were 20. Low levels of NAD+ causes signs of ageing and contributes to the development of age-related diseases. In summary, it is vital for youths and adults must maintain a high level of NAD+ to stay healthy. This requires us to take NMN foods and supplements.


Improves Muscle Endurance and Strength
NMN helps to boosts energy production through metabolism. This ensures that male muscles remain strong and in good condition for them to stay active. A high supply of NAD+ also slows down the ageing of muscles, making them capable of absorbing stress.
Prevents Liver fibrosis
Liver fibrosis is a condition caused by large amounts of scar tissue in the liver. It happens when the liver attempts to repair and replace damaged cells. There is evidence that increasing NAD+ levels with NMN can prevent liver fibrosis. NMN prevents the buildup of free radicals in liver cells and helps tissues to heal faster.


Promotes Fertility
Studies suggest that women experience their highest fertility at the age of 24. However, at 30, female fertility begins to reduce. A reason for this is age-related changes in the mitochondria of egg cell in the ovary. Developing studies suggest that NMN may improve the quality of the mitochondria and increase chances of pregnancy in women.
Slows down signs of ageing
True anti-ageing does not begin with moisturizers or your skincare routine. It actually begins in the cell. Over time, cells start to age due to chemical processes like oxidation and glycation.
Luckily, NMN provides cell with a regular supply of energy which allows cells with adequate ability to grow and regenerate. Women with a healthy rate of cell growth and multiplication enjoy anti-ageing properties like smooth skin, strong nails and darker hairs. 


Protects the Heart
Research believe that the average person breaths about 20,000 times a day. This means that the heart requires high energy because it works non-stop. Thus to keep the heart pumping smoothly, it needs NAD+ to help cells produce enough power. This is why heart cells need a steady supply of NMN.
Another research also discovered that high NAD+ levels promote blood circulation, which prevents high blood pressure and injuries to the heart. High blood pressure can cause an enlarged heart and blocked arteries that lead to strokes. Taking NMN can prevent abnormal heart enlargement and preserve the heart.
Increases Immunity
As adults grow older, their immune system declines. They fall ill easily, and it becomes harder for them to recover from illnesses such as the seasonal flu or even COVID-19. The body needs enough white blood cells to fight diseases. 
Taking NMN boosts NAD+ levels which help to reduce inflammation and cell survival during immune response and ageing. This way, the body can store enough cells to protect the body during disease attacks. There is also a developing study where high NAD+ provided positive immune defence against viruses like Covid-19.
Promotes Bone Formation
Many Older adults have Osteoporosis, and other bone-related conditions. Lack of new bone formation in the body causes weak, brittle bone structures. NMN has been found to increase the cells needed by the body to form new bones.
Protects Eyesight In Older Adults.
Many senior adults suffer from age-related eye disorders like AMD and cataracts. These conditions are mainly caused by cell death or cell damage induced by oxidative stress and inflammation. Studies suggest that NMN protects the eye, particularly the retina, from oxidative stress injury. This research believes that NMN reduces cell death, suppresses eye inflammation, and increases antioxidants in the eye.
Protects the Brain and Improves Memory
NMN and NAD+ combine to increase the process of glycolysis. This process is very vital because glucose is the only source of energy for the brain. To ensure normal brain function, NSM helps to maintain a constant supply of glucose in the blood.
Another study discovered that NAD+ decline significantly in the brain, particularly in a region called the ‘hippocampus. Boosting NAD+ levels through NMN supplementation prevents brain cells from dying when there is insufficient blood flow to the brain. In the long run, NMN can defend the elderly brain from Alzheimer’s and memory loss.
Lowers Risk of Obesity
NMN reduces the risk of age related weight gain. NMN promotes NAD+, which helps the body to perform metabolic processes, such as glycolysis. These metabolic processes help the body to convert fats and nutrients into energy and improve its exercise capacity. This process also protects the elderly from diabetes. With NMN, elderly people are assured of steady energy output from the food they eat.
Repairs DNA
Some environmental factors such as radiation and pollution may cause DNA damage to the body. Unfortunately, severe DNA damage in the body causes signs of ageing. The body has its natural process of DNA repair. This process consumes a lot of NAD+ to repair cells. Since NDA+ levels decline with age, taking NMN ensures an NAD+ boost in the body needed to repair our DNA.
What Food Contain NMN?
You can find NMN in foods, such as avocado, broccoli, cabbage and cucumber. However, it is suggested that NMN concentration in food is very low. You may need to use dietary supplements to increase your NMN to healthy levels than just eating foods.
Is NMN Supplement Safe?
NMN dosages up to 500mg have been considered safe in both human and animal experiments. When it was administered to humans, it was well tolerated. Since the sales of NMN as a dietary supplement, there have been few or no negative reports.
How Much NMN should I Take?
Recommended single oral doses NMN range from 100mg - 500 mg depending on age.
