What is the beneficial impact NAD+ peptide has on the heart? To find out the answer, keep reading!
Sir Arthur Harden found a component with a low molecular weight present in boiling yeast extract that may drive fermentation and alcohol synthesis in-vitro. This chemical was later named Nicotinamide Adenine Dinucleotide, or NAD+ for short.
It was discovered more than a century ago. Studies conducted in the years that followed revealed that the structure of NAD+ was composed of 2 mononucleotides that were covalently joined. These mononucleotides were Nicotinamide Mononucleotide, also known as NMN, and Adenine Dinucleotide. Furthermore, these studies revealed that the primary role of NAD+ and NADH was that of enzyme cofactors that mediated hydrogen transfer in either oxid.
NAD+ is one of the most prevalent and vital molecules in all creatures, from simple single-celled organisms like bacteria to complex multicellular species like humans. If we didn’t have NAD+, we’d be in a race against time to the grave. The operation of the cell’s power plants, the mitochondria, is dependent on this molecule in a significant way. Not only does NAD+ assist in transforming food into usable energy, but it also plays an essential part in guarding the integrity of our DNA and ensuring that our cells work as they should. This process helps protect our bodies from the degenerative effects of age and illness.
How does NAD+ work?
NAD+ functions as a shuttle bus within a cell, moving electrons from one molecule to another to carry out various chemical reactions and other operations. This essential molecule and its chemical counterpart, NADH, participate in various metabolic activities responsible for the cell’s energy production.
Without enough NAD+, the cells in the body would be unable to produce any energy at all, making it impossible for them to live and carry out their duties. NAD+ also regulates the circadian rhythm, the biological clock that determines when organisms sleep and when they are awake.
The Levels of NAD+ Decrease with Age
The levels of NAD+ in the body tend to drop with age, which may have significant repercussions for metabolic function and age-related disorders. The accumulation and progression of damage to DNA is a natural consequence of aging.
The disruption to the genetic code triggers the activation of several proteins, which are enzymes known as PARPs. PARPs can carry out DNA repair tasks because they take in NAD+.
It seems that the depletion of NAD+ caused by the activation of PARP throughout the aging process contributes to the development of different illnesses. PARPs are thought to contribute the most to all of these different processes that need NAD+, according to several different experts.
NAD+ is also used by enzymes that are part of our immune system. The more active the immune system is, the greater the amount of NAD+ used by the enzyme.
Sirtuins are a different group of enzymes that are capable of using NAD+. These proteins use NAD+ to control metabolism, keep chromosomes stable, and repair damaged DNA. Healthy aging and lifespan are both tied to the presence of these proteins. The accumulation of DNA damage and chromosomal instability that comes with aging causes sirtuins to consume an increasing amount of NAD+.
What Findings Have the Research Studies Revealed?
According to findings from several studies, NAD+ is capable of doing the following:
- Reduce the effects of becoming older
- Improve the function of the muscles
- Improve metabolic diseases
- Optimum performance of the heart
- Neuroprotective capabilities
Decreased levels of NAD+ are connected with the hallmarks of aging and various age-related illnesses, including metabolic disorders, cancer, and neurodegenerative diseases. The hallmarks of aging are the physical changes that occur as organism ages. It is effective in warding off age-related disorders and slowing down the aging process when NAD+ levels are restored by consuming the compound’s precursors.
It is imperative to note that increasing the levels of NAD+ has been demonstrated to increase the longevity of various experimental animal models, including worms, flies, and rats. Implications of NAD metabolism are changed in metabolic diseases.
Because of their suppleness, the arteries are a buffer between the pressure waves produced by the beating heart. However, with age, the arteries get stiffer, which is one reason that contributes to high blood pressure.
High blood pressure is one of the most prominent risk factors for cardiovascular disease. According to data provided by the CDC, cardiovascular disease claims an individual’s life every 37 seconds in the United States alone.
An enlarged heart and clogged arteries are two potential side effects of hypertension, which may also contribute to strokes. Increasing levels of NAD+ protects the heart, which improves the heart’s functioning.
NAD+ boosters have been shown to restore NAD+ levels in the heart to their baseline levels in mice, preventing damage to the heart that a reduction in blood flow would have caused. NAD+ boosters have also been proven in other research to be effective in preventing aberrant cardiac enlargement in mice.
