NMN supplements are marketed as a method to aid your body in turning back time however, how much do you need to take?
Wouldn’t it be great to set our body’s clock few steps? Now, it appears we could at the very least slow it down thanks to an increasing number of supplements that can increase the production of NAD+ to the body. Although all supplement makes bold claims however, do they actually provide any advantages and what are the possible adverse impacts?
What exactly is NMN?
NMN, also known as nicotinamide monnucleotide is a precursor to the essential molecule known as NAD+. Studies have shown that, not only is NAD+ supply the energy required to perform, repair and grow it can also help in stopping the ageing process.
As we age the body naturally becomes vulnerable to various illnesses and heart diseases, obesity and a host of other issues. This vulnerability is correlated with the decrease in NMN as well as NAD+ levels as documented by studies; in reality when we reach 50, we’ve only just half the amount NMN that we had in our 20s.
NAD+ is absorbed by enzymes and proteins that play an important function in repairing DNA damage as well as fueling our cells and keeping our immune and metabolic systems functioning well. However, it’s not just about keeping our systems in good shape and systems NAD+ may hold the key to stopping age-related decline.
If we can maintain NAD+ levels relatively high and we can slow down the aging process , and at times begin to slow it down slightly. This is the point where NMN plays a role. It’s an NAD+ precursor that the body uses to restore healthy levels NAD+.
The benefits of NMN supplements
Research into NMN is currently ongoing that includes rodent and human studies. Research has so far suggested a variety of NMN benefits, which include:
Reduced weight gain: Higher levels of NMN boost the metabolic system, which increases the body’s ability to transform food into energy. It can aid in decreasing the risk of being overweight. However, this should be done in conjunction with an active lifestyle and a healthy diet.
Reduce the risk of developing heart disease: The heart is active continuously throughout your day without taking a break. It generates huge amounts of energy and will require every ounce of NADplus it could.
Improved metabolic conditions Research is beginning to show that NAD precursors could help to reduce body weight, mitigate the adverse effects of high-fat diets and boost energy levels. A small study looked at the effects on NMN on women suffering from prediabetes. They found that the muscles’ capacity to process sugar increased.
Enhancing fitness and endurance of muscles Muscles and bones use fatty acids and glucose to function. NAD+ helps them to be metabolized into the body. Without it, the system is slowed down and the endurance of muscles decreases. A recent study on amateur runners found that NMN improves human aerobic capacity. Researchers believe this is because of increased oxygen usage in the skeletal muscles.
Improved cognitive function: Studies of Alzheimer’s disease demonstrated improved memory and cognition after NMN supplementation. This is likely due to NAD+’s capacity to boost many vital functions of the brain.
Enhancing symptoms of serious diseases Researchers are also examining the benefits specific to increased NAD levels in high blood pressure as well as liver health and diabetes.
In your body NAD+ produced through NMN supplement boosts the mitochondria’s activities microorganelles, which are essential for our metabolism. The cells’ powerhouses mitochondria convert oxygen and glucose into cellular energy. Without them, cells will not have energy and eventually die.
NAD+ also stimulates sirtuins a group of proteins that repair DNA and regulate homeostasis in our cells. Every time cells divide, the caps at those ends of DNA are smaller; the fraying and shortening process can damage our DNA, however, sirtuins help to slow down this process by stabilising the caps, also known as telomeres. Research in mice has shown they can be fed NMN can prolong telomeres, decreasing the chance of DNA damage.
It’s important to remember how sirtuins can be NAD dependent, meaning that they cannot function as they should without NAD. But when NAD production grows the sirtuin activity.
The side adverse effects of NMN supplements
Certain NAD boosters that are taken in high doses – have been linked to negative side effects, such as diarrhoea, nausea flushing, stomach discomfort and stomach discomfort. However, participants in research studies using NMN supplements have not reported serious side effects with dosages as high as 1,200 mg.
As for studies conducted in clinical settings, one study conducted in Japan discovered no adverse effects when doses were as high as 500mg. Another study on endurance showed no problems at doses between 1200mg and 1200 mg. One of the latest clinical trials used NMN supplements as placebo in 300 600, 900 and 300 mg dosages, without any signs of toxicity at any dosage. The research is ongoing however, there aren’t yet any serious safety concerns concerning NMN supplements.
The main safety issue however, is the sheer number counterfeit and low-quality imitations that are available. There are many products that offer the same promises however at only a fraction of the cost. Some of these aren’t completely NMN. They have instead been diluted with other compounds . This creates security concerns, particularly when the manufacturer hasn’t clarified what is included.
This is especially true if an organization manufactures its NMN in facilities that are not cGMP certified in which there is an increased risk of impurities. Be aware that , in the US, NMN is considered as a nutritional supplement, and therefore is not required to be tested for safety and effectiveness prior to being released to the market. However, NMN supplements are subject to postmarket inspection through authorities such as the Food and Drug Administration – which means that consumers have be aware of the brands they are able to trust.
Knowing the manufacturing process can help as well. There are three methods of manufacturing NMN:
Chemical synthesis: Labor-intensive and costly, this technique produces high yields and permits the precise control of the materials that are used for starting even though none of them originates through biological processes. It uses environmentally-damaging solvents and impurities and byproducts in the finished product can be difficult to remove.
Enzymatic synthesis: This method is costly, yet it produces greater yields and high quality. It’s considered to be a green process to produce NMN.
Fermented biosynthesis isn’t suitable for commercial production due to its low yields, but excellent quality.
To ensure safety, look for reputable brands that are open about their manufacturing processes and that have been independently vetted.
Instead of being concerned about the safety of the product most people are focused more on the cost of their products and comprehending the amount of NMN is required to attain the desired result. Because NMN is extremely difficult to make and is so difficult to manufacture, the products are rather expensive. It is therefore important to make sure you buy only the amount you require and not more.
Ideal dosage
Although there haven’t been any adverse reactions observed, there is no consensus regarding the appropriate dose of NMN. Numerous studies have examined the low doses. But, longevity experts such as Drs. Sinclair and Salzman believed that higher doses will yield more benefits. The 2022 study of clinical studies evaluating the effects of placebo 300 600, 900, and 300 mg doses showed the highest efficiency in the 900mg dosage. The endurance trial that examined dosages of 600, 300 and 1,200mg daily discovered the greatest impact on the middle and high groups, and averages out to an 900 mg daily dose.
Supplement manufacturers will typically make their own recommendations regarding the proper dosages based on their personal studies and observations. Some may suggest varying dosages based on weight, with higher doses recommended for those who weigh more.
Supplements for NMN are usually available in a range of 100mg to 500mg. The dosages are usually between two and six tablets. Look at the label of the manufacturer to find out how much they recommend you take.
The clinical knowledge about NMN supplements is constantly developing, with every trial and study increasing our knowledge just a more. What these studies have shown to date is that they appear to provide real advantages in terms of longevity and health. It also shows that the adverse effects are small.
