Guild of the Wild Last updated: August 25, 2026
Field Notes from the frontier of human performance, longevity, and adventure — field tested, truth told. Here's what that means legally.
Guild of the Wild is written by Dr. David Heitmann, DC, MS, and reflects his personal research, experience, and opinion. It is provided for educational and informational purposes only and is not medical advice, diagnosis, or treatment.Nothing in this newsletter, on this site, or in any related content creates a doctor-patient relationship. Always talk to a qualified physician or healthcare provider before making changes to your health, fitness, nutrition, or supplement routine — especially if you have an existing condition or are taking medication. Never disregard professional medical advice or delay seeking it because of something you read here.
Much of what's shared — CGM data, training experiments, biomarker tracking, adventure and recovery protocols — reflects n=1 self-experimentation. What worked for one specific person, body, and context is not a guarantee of results for anyone else. Individual results vary, sometimes significantly.

If a link is an affiliate link, we may earn a commission at no additional cost to you. We do not endorse products we haven't personally used, and no partnership changes the honesty of what's written here — if something doesn't work, that gets said too.
The views expressed are personal opinions based on available evidence, direct experience, and independent judgment. They do not represent the positions of any current or former employer, clinic, sports organization, or institution Dr. Dave has been affiliated with.
Content referencing adventure travel, endurance events, or physical training describes activities that carry inherent risk. Anything you choose to attempt based on this content is undertaken at your own risk and discretion.
Nothing here promises a specific outcome — health, financial, professional, or otherwise. The frontier is uncertain by definition; that's part of what makes it the frontier.
