Episode Details

n Episode 293 of the Fit Father Project Podcast, Dr. Anthony sits down with Cathy Eason from Berkeley Life, and a clinical nutrition practitioner with 30 years of experience, to break down one of the most overlooked molecules in men’s health: Nitric Oxide.

By age 40, your body has already lost nearly half of its ability to produce this critical signaling molecule — and by your 50s and 60s, production can fall to just 20% of youthful levels.

The drop is silent, but the consequences show up as low energy, poor circulation, high blood pressure, reduced exercise performance, and even issues in the bedroom.

Dr. Anthony and Cathy give you a practical, science-backed playbook covering the two pathways your body uses to make nitric oxide, the best foods to support them, why your oral microbiome matters more than you think, what’s wrong with most nitric oxide supplements, and how simple lifestyle habits like nasal breathing and breath work can make a real difference.

This episode also covers Berkeley Life’s own double-blind, placebo-controlled clinical research and how their test strips let you measure your own nitric oxide production at home.

If you care about your heart health, your energy, and staying strong and capable for your family, this is an episode you’ll want to share.
