Nitric Oxide

Nitric oxide is a crucial molecule in the human body, associated with various health benefits, particularly vascular health. Here are some key points about nitric oxide based on discussions by Andrew Huberman:

1. Production and Importance:

   • Nitric oxide promotes vasodilation, enhancing blood flow and nutrient delivery while assisting in waste removal from tissues. It is beneficial for the health of small capillaries, veins, and arteries throughout the body, including the brain and heart 1.
   • Alcohol-based mouthwashes can reduce nitric oxide production in the oral cavity, impacting its levels body-wide. Thus, avoiding such mouthwashes can help maintain optimal nitric oxide levels 1.

2. Boosters and Supplements:

   • Supplements like L-citrulline and L-arginine are used to increase nitric oxide levels. They are in the Arginine pathway, with L-citrulline converting to L-arginine in the body and lasting longer in the bloodstream 2.
   • These supplements, however, come with caution as the supplement industry is largely unregulated, and quality can vary significantly 2.

3. Nasal Breathing:

   • Nasal breathing is highly recommended over mouth breathing as it not only helps to inflate the lungs more effectively but also increases nitric oxide production. This nitric oxide then aids in dilating the vasculature, enhancing blood flow and improving overall respiratory and body health 3.
