What is NAD+?
“NAD” is an abbreviation for “nicotinamide adenine dinucleotide”. Among the most prevalent and essential chemicals in cellular metabolism, it is found from bacteria to primates. If NAD+ didn’t exist, we would probably die within a minute, if not seconds. These molecules are essential to the activity of cell-generating units called mitochondria. NAD+ not only supports the conversion of food into energy but also plays a vital function in maintaining the DNA structure. NAD+ guarantees that our body’s natural defense genes are working properly and protects us from illness and aging.
What functions are performed by NAD+ in our body?
When it comes to electron transfer, NAD+ acts as a shuttle bus, moving electrons from one cellular molecule to the other. Electron transfer occurs in a variety of metabolic processes when it is combined with its molecular counterpart (NADH). These metabolic processes produce adenosine triphosphate (ATP), the body’s “energy” molecule. Without adequate NAD+ levels, ATP synthesis may be inhibited.
NAD+ also regulates the sleep/wake cycle, among other things. It is NAD+ that drives sirtuins, which control metabolism and keep chromosomes in a constant state. The molecule also contributes to the repair of DNA that has been damaged.
What are the benefits of NAD+ Peptides?
There are several advantages of using NAD+ Peptide. Some of which are as follows:
- Reduces the aging process
- Lower anxiety and stress
- Boosts DNA repair and maintenance
- Enhances healthy sleeping patterns
- Tends to increase energy levels and metabolism
- Keeps cell cycle healthy
- It regulates the immune system.
Why does the NAD level in our body tend to fall?
As humans age, their NAD+ levels decrease, which may have major consequences for metabolic activity as well as age-related disorders.
DNA damage occurs as an individual age. When DNA damage occurs, the PARP enzyme is activated. NAD+ is required for PARP to repair DNA. During this procedure, PARP breaks NAD+.
When NAD+ is broken by PARP activation during aging, it can lead to a variety of illnesses. Animal cell models of illnesses such as cellular stress activate PARP because DNA damage occurs. According to the findings, NAD+ depletion in these illnesses is largely caused by PARP activation. NAD+ deficiency is also associated with DNA damage and inflammation in disorders.
NAD+ is consumed by enzymes in our immune system. To a greater extent, the immune system’s activity affects how much NAD+ is used by the enzyme. NAD+ is depleted as we age due to an increase in immune system enzyme levels.
As we age, sirtuins, another family of NAD+-using enzyme, can cause the body’s NAD+ levels to drop. As well as preserving chromosomal stability, sirtuins are necessary for DNA repair. Sirtuins use more NAD+ when DNA damage and chromosomal instability increase with aging.
The Bottom Line
In a nutshell, two amino acids make up the powerful peptide-protein Nicotinamide Adenine Dinucleotide (NAD+) (hence called dinucleotide). To control critical biological activities, such as metabolism and energy production, DNA repair, and immune regulation, NAD+ is an essential endogenous peptide that is involved in over 500 enzymatic reactions in the human body. Research has demonstrated that exogenous NAD+ helps maintain a proper amount of NAD+ in the body, promoting a healthy aging process and good bodily function.
