The vitamin that slows aging from the inside

It’s hard not to notice the outward signs of aging. When you look in the mirror, you can clearly see a new line, wrinkle or age spot. But do you ever think about what’s really happening on the inside of your body?

When it comes to the aging of your organs, it’s way too easy to live by the motto “out of sight, out of mind.” The only time you’re really forced to confront your internal aging is when something goes wrong… and that’s usually pretty serious.

After all, a wrinkle won’t kill you, but if one of your vital organs stops working right, that definitely can.

The reason you see the signs of aging written all over your face is that your body’s largest organ (your skin) stops regenerating as quickly and effectively as it did when you were young.

Well, the same exact thing happens to your internal organs, making it harder for them to bounce back from injury, leaving you vulnerable to a whole slew of age-related diseases.

But don’t worry… you don’t have to sit back and wait as your vital organs gradually lose their vitality. There is something you can do right now to inject life-force back into your body.

Researchers have discovered a vitamin that restores your organs’ regenerative powers and lengthens your life: nicotinamide riboside.

I know, the name sounds super scientific, but it’s really just a form of vitamin B3…

This vitamin has been studied by a lot of researchers in recent years, and its anti-aging powers are pretty jaw-dropping. The most recent research published in Science showed that elderly mice who were given nicotinamide riboside experienced improved muscular regeneration (your heart is a muscle, by the way) and lived longer than mice who weren’t given the vitamin.

“This work could have very important implications in the field of regenerative medicine,” said lead researcher Johan Auwerx. “We are not talking about introducing foreign substances into the body but rather restoring the body’s ability to repair itself with a product that can be taken with food.”

If you’re wondering how nicotinamide riboside can have such amazing anti-aging results, the answer is in your cells…

Nicotinamide riboside boosts your body’s natural production of nicotinamide adenine dinucleotide (nad+), an enzyme that helps power your mitochondria. Scientists call mitochondria the “powerhouse” of the cell because that’s where your cells produce their energy. And scientists have realized for the first time that the proper functioning of mitochondria is critical to your stem cells — the same stem cells that regenerate your organs.

“We demonstrated that fatigue in stem cells was one of the main causes of poor regeneration or even degeneration in certain tissues or organs,” said Hongbo Zhang, PhD student and researcher in the study.

But Zhang’s study is not the first one to show how valuable this form of B3 may be for deterring the effects of aging…

Research by a team at Cornell, found that nicotinamide riboside could possibly “ameliorate metabolic and age-related disorders” like type 2 diabetes after they saw improved insulin sensitivity in mice.

It makes sense that improving the way your body handles insulin could be both age-defying and life-lengthening considering insulin’s role as your body’s master mediator.  There are small segments of populations all over the world where centenarians are more numerous than normal. Many researchers, including Dr. Michael Cutler, speculate these long-lived individual are thriving because they discovered how to balance their master hormone — insulin.

And if you’re ready to give your fatigued stem cells a much-needed energy boost, try nicotinamide riboside. Trace amounts are available in some foods (like milk) but not in high enough doses to have an effect. If you’re really serious about recharging your stem cells and regenerating your organs, you’re going to have to go out and get a supplement. Most nicotinamide riboside supplements on the market recommend a dosage of about 250 mg per day. Get started now, and you may just defy your body’s aging process in a whole new way.
