Nitric Oxide Nuances that Practitioners Need to Know | E43

Why do so many patients with textbook risk factors still struggle with high blood pressure, fatigue, and poor circulation even after the obvious fixes? On this episode of Functional Medicine for Real-World Impact, host Tracy Harrison makes the case that nitric oxide challenges are often misunderstood when practitioners focus only on production.   Tracy reframes nitric oxide and hypertension as a story about loss, not just lack. She explains why some patients may be making nitric oxide, but losing too much of it through oxidative stress, inflammation, poor oxygenation, metabolic dysfunction, toxicity, or other upstream drivers. This distinction changes how practitioners can think about endothelial dysfunction treatment, especially in patients who are not responding to standard nitric oxide support.   She also addresses factors that are easy to overlook in clinical practice. eNOS uncoupling can turn the enzyme meant to support nitric oxide production into one that contributes to oxidative stress. Tetrahydrobiopterin (BH4) deficiency can block nitric oxide synthesis in a separate, often overlooked way. Tracy also unpacks the oral microbiome’s role in nitric oxide production and explains how something as routine as mouthwash may interfere with a patient’s progress.   This conversation gives practitioners a more complete map of nitric oxide deficiency causes and a reason to look upstream before reaching for another supplement.   Episode Breakdown: 00:00 Nitric Oxide Nuances Practitioners Need to Know 01:35 Five Early Signs of Impaired Nitric Oxide Signaling 06:59 Two Pathways the Body Uses to Make Nitric Oxide 09:24 Why Nitric Oxide Loss Matters More Than Production 14:12 How eNOS Uncoupling Triggers Oxidative Stress 17:18 Tetrahydrobiopterin (BH4) and Nitric Oxide Synthesis 19:24 Oral Microbiome and Nitric Oxide Production 23:49 Nitric Oxide's Role in Mitochondria and Brain Health 26:11 Building a Clinical Framework for Nitric Oxide Support   SAFM Links: Take SAFM’s 10 CME course - The Essential Gut Deep Dive Get weekly Clinical Tips in your inbox  Learn more about SAFM’s practitioner training Subscribe to our YouTube channel Access quick clinical tips on Facebook  Podcast production and show notes provided by HiveCast.fm
