Episode 66: SPONSORED | New Hope for Fibromyalgia Patients with Erik Lundquist, MD

As a clinician interested in participating in research, it’s very exciting to see others jumping into the research conversation, too. Today I talk to Dr. Erik Lundquist, who heads a large, integrative clinic out in Southern California. Erik recently completed a clinical pilot study looking at the use of SPMs (just 2 gelcaps per day) in patients diagnosed with fibromyalgia (Dr. Lundquist reports that the bulk of these patients have underlying mold exposure or Lyme as the primary etiology for FMS)...

Episode 65: Bacteriophages in the age of antibiotic resistance - Drs. Paul Turner and Benjamin Chan

Once upon a time, in a pre-antibiotic world, bacteriophages were a hot research topic in this country and elsewhere. In the 1940’s, Eli Lilly had seven OTC bacteriophage products available – good for everything from abscesses to URIs and mastoiditis. However, with the advent of antibiotics, the research into and use of phages ceased in the US. But in the age of antibiotic resistance, we’re back at phage research, and its wildly interesting and extremely important to explore. Phages are bacterial...

Episode 62: SPONSORED Methionine Metabolism and Methylation with Dr. David Quig

I enjoy discussing all things nutritional biochemistry, and few minds are more engaging to chat with than David Quig, PhD, VP of Scientific Support at Doctor’s Data. In this NFFM podcast, we’re drilling down into the laboratory assessment of methylation and sulfuration. As Dr. Quig makes clear (yet again)--- while we might make some *basic* inferences around methylation activity by looking at a person’s SNPs, SNPs are not our destiny (thank God!). Ultimately, SNP assessment doesn’t hold a candle...

Episode 58: SPONSORED Borrelia Research & Clinical Strategies using Botanical Antimicrobials

Lyme disease (and co-infections) can be tough to treat. The Lyme spirochete, Borrelia burgdorferi, has adopted loads of devilishly clever cloaking devices – from thriving in biofilm to existing in pleomorphic forms – to ensure survival despite aggressive treatment. Enter botanical therapy. With or without concurrent antibiotics, botanical combinations are an essential component of the FxMed clinician’s toolkit.

Episode 56: SPONSORED Advances in Stool Testing: The GI-MAP™ GI-Microbial Assay Plus

DSL’s GI-MAP stool test is, as CEO Tony Hoffman states, “a clinician diagnostic tool;” it’s not a microbiome test. Yes, of course the GI-MAP looks at the microbiome, but it's not a broad sweep of the myriad of bugs taking up residence. Rather, it’s a carefully curated investigation of organisms with demonstrated imbalance potential, be it pathogenic or dysbiotic in nature. The test is designed to be user-friendly, interpreted rapidly, logically, providing clearly actionable data that, when addre...

Episode 55: Plant Medicine, Photonutrients, and the Health Benefits of Eating a Rainbow

Dr. Deanna Minich preaches: Eat a rainbow. Why? There are over 700 carotenoids found in plants – all bioactive, and generally pleotropic (ie: they do more than one thing in the body). We don’t need tons of any single carotenoid, and indeed – if anyone recalls the beta carotene smoker study from the early 2000’s, too much of a single compound could arguably be toxic. But variety is essential. And amazingly, certain groups of carotenoid colors favor certain organs. Think “orange for ovaries”; blue...

Episode 48: Mastering Diabetes with Dr. Mona Morstein

Dr. Mona Morstein has focused the bulk of her career on treating all types of diabetes (DM). In late 2017, she published the a superb 500+ page very well-referenced book on the topic, titled Master Your Diabetes: A Comprehensive, Integrative Approach for Both Type 1 and Type 2 Diabetes. Despite written in layman language, clinicians will find it meaty enough to be useful in practice – I especially like the sections on DM complications. In our conversation, we look at the four main types of diabe...

Episode 45: Acupressure Tapping in Clinical Practice - A conversation with Jessica Ortner

Anxiety can get in the way of patients achieving their health goals—especially when a practitioner recommends significant lifestyle and nutrition changes. Patients may feel suffocated by the new regimen and then make changes for a while but revert back—or they may not make them at all. The Emotional Freedom Technique, also known as tapping, can help patients ease anxiety and better achieve their health goals. It can also help with the subjective experience of pain or be used in service of a spec...
