NAR Revival (NAD+) has always existed. Until recently, it has been used by people to fight against aging with antioxidants. It even claims to be able to rejuvenate. It sounds like a trick of a liar, right? What is it in fact? Let us understand it from a scientific point of view.
Before understanding the role of NAD Revival (NAD+), we must first review one of the middle school biology courses-DNA.
The cause of aging-DNA damage?
DNA is a kind of genetic material, which records all the information of our body, our appearance, fingerprints, bones, the structure of various organs, etc... all are recorded in our DNA. During our growth process or after injury, the cells will replicate themselves and repair the wound to its original appearance. However, when DNA is damaged, the copied cells may not be healthy, so the repair process and results will be affected. One of the more well-known examples is that when DNA is damaged by mistakes, cancer cells are replicated to cause cancer.
After DNA is damaged, although the human body has a mechanism to repair DNA, when the speed of repairing DNA is not as fast as DNA damage, people are prone to ageing.
Harvard experiment: rejuvenation is no longer a myth
David Sinclair, a PhD from Harvard Medical School from Australia, and other scientists from Germany and Canada formed a team. A study on NAD+ was done, which was also published in Science in 2017. The study found that NAD+ can make mice's DNA repair faster and better.
They compared young mice (three to four months old) with older mice (about two years old). Before the experiment started, younger mice contained more NAD+ than older mice. Then they added NAD+ to the water that the older mice drank. The concentration of NAD+ in the older mice rose after a few hours, proving that it had been absorbed by the body. In less than a week, the muscle tissues of older and younger mice have become indistinguishable.
Because DNA is damaged for different reasons, it will damage DNA with age, exposure to certain chemicals, exposure to ultraviolet rays or X-rays, which affects the body's self-repair process. But when the body has enough NAD+, it can activate the mechanism of repairing DNA and restore the DNA to a younger state.
How to supplement NAD+? What are the effects of antioxidants in fighting aging?
NAD+ is very important in anti-aging, and its source is mainly from vitamin B, but if you want to absorb a large amount of NAD+, you must supplement it outside of your daily diet, and health care products are a good choice.
When you have enough NAD+, you can also absorb enough antioxidants to get twice the result with half the effort. Because antioxidants can prevent or slow down the damage caused by free radicals and unstable molecules in the body to cells, blood vessels and various organs, and achieve long-term anti-aging effects.
Antioxidants generally come from various plants and fruits. Among them, β-carotene, anthocyanin, vitamin C and E are the most widely known. Antioxidants can also be absorbed from health products. It is also a good choice to choose health products containing pine alcohol, SOD B, astaxanthin and other ingredients.
