Enter your symptoms and get research-backed insights, red flag warnings, and a list of questions to bring to your doctor.

No. This tool is an educational resource that helps you understand possible conditions related to your symptoms and prepare informed questions for your doctor. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider.
The tool matches your reported symptoms against a knowledge base of 23 common and serious conditions compiled from medical literature. It scores each match based on symptom overlap, adjusts for demographic factors (age, sex, ancestry), and flags any red flag symptoms requiring immediate medical attention.

Use the "Questions to Ask Your Doctor" section to prepare for your next appointment. Print or screenshot the results and bring them with you. Your doctor can use this as a starting point for further evaluation.
Red flags include sudden severe headache, chest pain, coughing blood, blood in stool, unexplained weight loss, sudden vision changes, difficulty breathing, sudden numbness (especially one-sided), seizures, and suicidal thoughts. These always warrant immediate medical attention — call 911 or your local emergency number.
Many chronic symptoms — fatigue, brain fog, anxiety, joint pain, skin problems — share hidden root causes that standard medical visits often miss. These include nutritional deficiencies (vitamin D, magnesium, omega-3s), gut health issues (intestinal permeability), methylation problems (MTHFR gene variants), chronic inflammation, blood sugar dysregulation, and environmental toxin exposure. Our tool cross-references your symptoms against 12 root cause categories based on research from Dr. Rhonda Patrick and the Weston A. Price Foundation.
Dr. Rhonda Patrick is a biomedical scientist and host of the FoundMyFitness podcast, known for her research on micronutrients, aging, and disease prevention. She takes a science-forward approach backed by peer-reviewed studies. Sarah Pope (Healthy Home Economist) is a leading voice in the Weston A. Price Foundation tradition, which promotes the nutritional research of Dr. Weston A. Price, a dentist who studied traditional diets worldwide. This tool uniquely synthesizes both perspectives to give you a more complete picture.
Based on common root causes, consider asking about: 25(OH)D (vitamin D), RBC magnesium (more accurate than serum), omega-3 index, hs-CRP (inflammation), fasting insulin (not just glucose), homocysteine (methylation), MTHFR genetic test, comprehensive stool analysis (gut health), and a heavy metals panel. Many of these are not included in standard blood work but can reveal hidden drivers of chronic symptoms.
If you've been dealing with chronic fatigue, brain fog, anxiety, joint pain, or digestive issues, you're not alone — and the answer might not be what you expect. Conventional medicine often treats symptoms individually, but a growing body of research shows that many chronic symptoms share the same underlying drivers: nutritional deficiencies, gut dysfunction, chronic inflammation, and environmental exposures.
Dr. Rhonda Patrick, a biomedical scientist who runs the FoundMyFitness podcast, has extensively researched how micronutrient deficiencies drive chronic disease. Her work highlights that vitamin D deficiency affects over 40% of American adults and regulates more than 1,000 genes involved in immune function, mood, and inflammation. Magnesium deficiency — present in an estimated 50-80% of Americans — is involved in over 300 enzymatic reactions and is rarely caught by standard blood tests (serum magnesium is a poor marker; RBC magnesium is more accurate). Omega-3 deficiency contributes to brain fog, depression, and chronic inflammation, with most Americans having an omega-3 index well below the target range of 8-12%.
Both modern research and traditional nutrition emphasize gut health as foundational to overall wellness. When the intestinal lining becomes permeable — often called "leaky gut" — undigested food particles and bacterial toxins (lipopolysaccharides) enter the bloodstream, triggering systemic inflammation that can manifest as joint pain, skin problems, brain fog, anxiety, and autoimmune symptoms. The Weston A. Price Foundation, through voices like Sarah Pope (Healthy Home Economist), has long advocated for gut-healing foods: bone broth rich in gelatin and glutamine, lacto-fermented vegetables like sauerkraut and kimchi, and traditionally prepared dairy like kefir and yogurt.
The MTHFR gene variant (C677T and A1298C) affects how your body processes folate and regulates methylation — a biochemical process critical for detoxification, DNA repair, and neurotransmitter production. Up to 40% of the population carries at least one variant, and many don't know it. Symptoms can include fatigue, anxiety, depression, brain fog, and elevated homocysteine levels. Dr. Patrick recommends genetic testing and switching from synthetic folic acid to methylfolate (5-MTHF) if positive.
The modern environment introduces stressors that didn't exist a century ago. Industrial seed oils (soybean, corn, canola) now make up 8-10% of American calories — a 1,000-fold increase — and promote chronic inflammation through excess omega-6 linoleic acid. Environmental toxins including heavy metals, PFAS, BPA, and phthalates accumulate in the body and disrupt hormones. Glyphosate (Roundup), detected in 80% of Americans tested, may disrupt gut bacteria and chelate essential minerals. Both Patrick and Pope recommend reducing these exposures as a foundational health step.
This symptom checker is the only free tool that combines condition matching with root cause analysis from both science-forward (Dr. Rhonda Patrick) and ancestral nutrition (Weston A. Price Foundation) perspectives. Enter your symptoms above to see which hidden root causes may be contributing to how you feel — along with specific tests to ask your doctor about.
