"This coenzyme is at the edge of the fight against ageing!"

link to buy NAD+ is a coenzyme present in all the cells, and is necessary for the electron transfer process during the reactions of our metabolism to produce our ATP energy!

Cells and evidently humans just can't live or survive without NAD+.

Scientists have discovered that most deaths of our cells and most diseases happen when our cellular stock of NAD+ is totally depleted.

NAD+ is also crucial for cells communication and signalling, and its absence completely disorganises our organism!

The company Biotrends (based in Hong-Kong) is the only one in the world to allow individuals to access this priceless product, at the cutting edge of scientific discoveries in the domain of fighting ageing.

NAD+ promotes overall health and longevity

NAD+ is creating quite a buzz in scientific circles.

 Nicotinamide Adenine Dinucleotide, or NAD+ for short, is used by every cell in the body. NAD+ is important because it is a big player in the energy production process within the mitochondria. Sirtuins, a class of enzymes well known for their role in regulating ageing, need NAD+ to do their job. And, research tells us that the tight integration between NAD+ availability and sirtuins activity is the major driver in controlling ageing factors and promoting longevity.

NAD+: A co-enzyme used by every living cell

NAD exists in two forms: NAD+ and NADH. NAD+ is the oxidized form of NAD. NAD+ levels decrease as we age, and scientists have established a solid inverse relationship between NAD+ levels and ageing.  

How does NAD+ work?

NAD+ sits at the heart of the energy production process that occurs within the mitochondria – aptly called the ‘powerhouse of the cells’. How does it help in maintaining overall health and promoting longevity?

  • NAD+ improves mitochondrial functions
  • NAD+ activates Sirtuins, family of enzymes linked with regulating lifespan

Let’s explore the role of NAD+ in more detail.

NAD+ improves mitochondrial health

The cells in our body go through cycles of reproduction growth, repair and survival – and require tremendous energy to perform these myriad functions. Every cell in our body produces its own energy with all the action taking place in the mitochondria – tiny organelles within the cells. The energy is produced in a complex series of redox reactions, where NAD+ keeps shuttling between two forms; NAD+ and NADH.  

NAD+ accepts electrons that are released during the burning or oxidation of organic fuels (fats, glucose), and in turn is reduced to NADH. NADH transfers the electrons in this ongoing chain of redox reactions – eventually resulting in ATP synthesis in a complicated yet highly organized process called oxidative phosphorylation. Clearly, NAD+ drives this process forward – that is, it facilitates the transfer of energy from the food to our cells – and thereby helps cells carry out their numerous functions that are so critical to our sustenance, physical and mental well-being, and survival.

What happens when NAD+ levels decline?

Reduced levels of NAD+ means the energy transfer takes a massive hit – resulting in impaired mitochondrial functions and increased oxidative stress, which in turn manifest as:

  • Reduced energy (ATP) production
  • Reduced heat production
  • Increased generation of damaging free radicals, causing damage to DNA, proteins and lipids
  • Reduced cellular ability to perform basic functions: healthy division, growth and repair damage triggered by oxidative stress
  • Disturbed metabolic pathways (causing metabolic imbalance, insulin resistance, unbalanced sugar levels)
  • Chronic inflammation
  • Cognitive dysfunction

Mitochondrial dysfunction is believed to be one of the main reasons behind the symptoms of ageing, such as physical and cognitive decline, loss of energy and fatigue. Not surprisingly, with the mitochondria not working as smoothly and efficiently, cells become vulnerable to oxidative stress, hence trailed by premature ageing and age associated diseases such as heart failure, type 2 diabetes, insulin resistance, obesity, hearing loss, vision loss, Alzheimer’s disease and cancer.

NAD+ and Sirtuins: NAD+ activates Sirtuins

Internal structure of a cell.

Playing important roles in the process of ageing and mitochondrial fitness are sirtuins – SIR2 or silent information regulator 2 proteins. This family, so far as current research has identified, consists of seven enzymes (SIRT1–7). In mammals, Sirtuins control how the body responds to energy metabolism and stress – two factors at the core of the ageing process.

While sirtuins are found in different compartments of a cell, such as nucleus, cytoplasm and mitochondria, and may have unique functions, the predominant role of Sirtuins can still be summed up as:

  • To protect cells from stress and,
  • Enhance cellular capacity to develop resistance against stressors, survive and self-preserve, thus contributing to increasing life span.

And Sirtuins are dependent on NAD+ for their activity. In fact, Sirtuins also act as a substrate for other enzymes including bacterial DNA ligase, Poly-ADP-ribose Polymerases (PARPs) and CD38, with all these enzymes playing important role in cell survival. This competitive use of NAD+ among so many related ‘consumer’ enzymes is also one of the factors why NAD+ levels decline as we age.  

Sirtuins: The magic behind the effects of calorie restriction (CR)

A low-calorie diet is one of most effective and proven strategies to keep ageing at bay. Even long before modern scientific studies, many traditional systems of medicine, such as Ayurveda, have long believed that calorie restriction (CR) is the road to achieve a long, healthy life. So, what is the mystery behind CR and anti-ageing benefits? How come depriving the body of calories can make you live longer?

It seems that Sirtuins hold the key to this puzzle. Of course, one of the theories backing the CR effect is that it reduces the formation of free radicals, invariably formed when our cells use nutrients and oxygen to create energy during the oxidative phosphorylation process. It is something like when a vehicle burns fuel and releases smoke as a by-product. With reduced generation of free radicals, cellular structures experience less oxidative damage, and function better.

However, more and more studies indicate there is something more interesting happening at the backend. It appears that CR drives some very targeted bio-chemical responses, which helps cells preserve themselves and survive under unfavorable conditions. And no points for guessing, sirtuins are believed to drive these biological responses.

CR achieves the anti-ageing effect by activating sirtuins. To be precise, CR increases the expression of SIRT1, SIRT3 and SIRT5, enzymes that are known to regulate the expressions of genes associated with ageing. So, increasing the bio-availability of cellular NAD+ and increasing Sirtuins activity to extend the lifespan (that mimics CR mechanism) makes complete sense as a strategy to combat ageing and diseases of ageing.

NAD+ and Sirtuins: The Complex Relationship

Sirtuin 6 protein. linked to longevity.

 In the mitochondria, NAD+ levels mirror the energy status of the cell. And sirtuins function as sensors; detecting the variations in the NAD+ levels and processing this information to help cells adapt and survive fluctuating energy requirements. NAD+ availability decreases as we age, negatively impacting Sirtuin activity.

The complex relationship between NAD+ and Sirtuins helps in controlling metabolic and longevity pathways. Studies show that this tight integration between the availability of NAD+ and Sirtuins activity helps to:

  • Maintain the communication between the nucleus and mitochondria at a cellular level and;
  • Maintain the inter-tissue communication, more specifically between the hypothalamus and adipose tissue at a systemic level.

The integration of NAD+ and sirtuins orchestrates this important communication, both at cellular as well as systemic level. If this orchestration works smoothly, the result is melodious harmony that keeps cells healthy. However, with low NAD+ levels, this communication gets disrupted. Cells lose their ability to create sufficient energy and the process of ageing accelerates. Dr. David Sinclair, Harvard Medical School Professor of Genetics commented that “this communication network is like a married couple—when they are young, they communicate well, but over time, living in close quarters for many years, communication breaks down. And just as with a married couple, restoring communication solved the problem.”

Overall, NAD+ dependent Sirtuins protects against premature ageing and associated diseases through various mechanisms, such as:

  1. Deacetylation of proteins like histones
  2. Regulating metabolism and circadian rhythm
  3. DNA repair
  4. Boosting mitochondrial functions and response in the face of external or internal stress, for example fasting and oxidative damage
  5. Reducing inflammation in the body

NAD+ Benefits:

Boosts energy and fights premature ageing

Improves mitochondrial efficiency. Enhances energy metabolism. Reduces Oxidative stress.

Emerging research and scientific studies are all pointing to the role of NAD+ in improving human lifespan, quality of life and all-inclusive health. The evidence is promising and shows that boosting NAD+ levels can help us achieve a healthy and disease free life. Since oxidative stress and mitochondrial dysfunction are implicated in ageing and most heath conditions, NAD+ indeed is fast emerging as a real possibility to prevent and even reverse a wide range of chronic ailments, including:

  • Metabolic disorders, such as obesity, insulin resistance, type 2 diabetes
  • Neuro-degenerative disorders, such as Alzheimer’s disease, Parkinson’s disease, dementia
  • Cancer
  • Cardiovascular disorders
  • Inherited mitochondrial diseases
  • Vision loss
  • Hearing loss

The Pr Sinclair had already found the anti-ageing Resveratrol!

Prof. Sinclair of the Medical School of Harvard University became famous last year thanks to his scientific study which has rejuvenated mice from 60 to 20 years.dr-sinclair-youtube

But he and his Australian team had already discovered the anti-aging effects of resveratrol 10 years ago!
He is therefore not new in this field, and he has been looking for molecules against ageing for more than 20 years.

After resveratrol they decided to develop molecules even more powerful. The NAD+ had been discovered for several decades, but with his tests, Pr Sinclair showed the full potential of the NAD+ against aging!
It is therefore not the invention of a new molecule, but the discovery of the cellular mechanism that this coenzyme can repair, and thus prevent cell death and even make it possible to rejuvenate them.

Here is a small documentary published on Yahoo News, I transcribed it partially:

Prof. Sinclair has been studying aging for over 20 years. He participated in the discovery of resveratrol and its benefits. They discovered that by giving resveratrol to supercharged mice, they remained young and thin.

It is then that the frenzy for red wine and its resveratrol has started.

Prof Sinclair says they have made good progress since this discovery and are working on even more effective molecules.

 Prof Sinclair: NAD is our latest discovery. For example you can lengthen the life of a mouse that has liver cancer. We hope that this molecule will help humans with cancers.

03mn00: Pr Sinclair: Our human cells contain mitochondria, and this is very important against aging because without them the cells die within seconds. So it’s vital, energy is produced.
And when we age, these small batteries nece ssary to produce energy diminish much, they disappear.
And this molecule that we discovered makes it possible to reverse very quickly the aging of these mitochondria, in such a way that they become young again.

03mn30: Pr Sinclair: One of the most important points we have studied is the possibility of protecting the brain because it is useless to keep the body young if the brain does not work properly.

So we looked at whether these protective effects spread to the brain, and the answer is yes!

Mice are thus protected against Alzheimer, Parkinson and others, and they become even more intelligent.

dr-sinclair-youtube-nad-cerveau
 Despite numerous attacks on their work, Professor Sinclair’s team continues to publish his findings, and no one has ever provided any evidence against the validity of their results.
We check our studies, we reproduce them several times, and the results are always there.

04mn20: Journalist: Prof Sinclair is so sure of his results that he himself tries the molecules they have discovered.

04mn25: Pr Sinclair: It is common knowledge that I have been taking resveratrol for 10 years already, and I feel good. My parents have been taking it for 10 years too, and they are still in good shape at over 70 years old.
My father is 75 years old and is in better shape than I am!

05mn25: Pr SInclair: I do not see any limit to the human lifetime. Let us live up to 100 years, I have no doubt. I do not doubt that one day we will live until 150 years, on the other hand I do not know when it will happen.

Here Prof Sinclair explains his career and his discoveries, including resveratrol, on TED in 2013:

dr-sinclair-youtube-tedx
I hope to have time to translate other documents on the NAD+ because I have found many others, but do not wait any longer to try it.

We are really in an incredible time, where scientists have the means to study closely the functioning of our bodies and find ways to repair it and prevent it from degrading.

The future is better than we can imagine!
