Perhaps by now, you’ve heard of the glymphatic system. Personally, I’ve seen it be a subject both popular media and medical journals are devoting more and more attention to. But, what exactly is the glymphatic system?

This may come as a bit of a surprise to learn, but it’s your brain’s other circulatory system. Yes, your brain has a second circulatory system! This newly discovered pathway is used to rid the brain of the byproducts of metabolism. Think of it as how the brain takes out the garbage. We’re also now learning it’s an important means for transporting important chemicals around the brain, like glucose and fatty acids.

Certainly, the performance of the glymphatic system is something we want to do, and it’s a good thing we’re seeing more research done to determine how to do this. One finding that seems to be sticking out: improving the quality of our sleep ends up improving the function of our glymphatic system. Let’s explore that further in today’s video.

The science of you, working better.

There’s a crucial molecule in your body that helps control your circulation, your energy, your stamina, your heart—even your sharpness of mind. It’s called nitric oxide.

After age 40, your body makes less and less of it. That means less blood flow. Less stamina. Less of you. But now there’s N1O1 nitric oxide lozenges, developed by Dr. Nathan Bryan — the world’s leading nitric oxide researcher.

I take them twice a day, especially before my workouts, to support healthy circulation and boost oxygen delivery to my muscles and brain. 

N1O1 is designed to naturally restore your body’s nitric oxide levels, and goes to work in minutes, releasing nitric oxide directly into your bloodstream, and helping you feel the way you’re supposed to feel.

More energy. Better blood flow. Sharper focus. Day after day.
