Could Gluten be Causing Your Symptoms? with Dr. Peter Osborne. Functional Gynecologist Podcast #61.

Podcast episode (YouTube) hosted by Dr. Tabatha Barber interviewing Dr. Peter Osborne about gluten, grain sensitivity, and how gluten contributes to autoimmune and other systemic symptoms. Key points: gluten defined both as gliadin (wheat/barley/rye) and more broadly as alcohol‑soluble seed proteins in grass-family seeds (corn, rice, oats, sorghum, etc.); many patients improve on wheat/barley/rye-free diets but may plateau due to cross-reactive grains and hidden exposures — Osborne advocates a stricter "true gluten free" (grain-free) approach for many. Gluten can cause non-GI presentations (neurologic, skin, thyroid, joints), and standard tests (biopsy, serology) have limitations and false negatives. He emphasizes genetic HLA‑DQ testing for predisposition, comprehensive nutrient testing (prefer lymphocyte-based measures for longer-term status), and addresses common deficiencies (vitamin D, B12, iron, zinc, omega‑3). Practical recommendations include vitamin D maintenance/therapeutic protocols, probiotics, finding functional nutrition-trained providers, and lifestyle fundamentals (diet, sunshine, sleep, exercise, clean air/water, social support).

Questions this video answers

Vitamin D, vitamin B12, iron, zinc, and omega‑3 fatty acids.

Approximately 6,000 IU/day (he suggests 6,000 as a recommendation; 5,000–10,000 discussed for response ranges).

A 25‑OH vitamin D level between about 70 and 100 ng/mL, with a goal of keeping it above 50 ng/mL once stable.

150,000 IU/day for 3 days, then 100,000 IU/day for 3 days, then 50,000 IU/day for 3 days (sequential high-dose protocol described).

HLA‑DQ genotype (HLA‑DQ alpha and beta alleles).
