Are you getting real nutrition, or just expensive synthetic substitutes?

In this episode of Walk, Don't Run to the Doctor, Miles Hassell MD breaks down the critical differences between the complex nutrients found in whole, unprocessed foods and the isolated, laboratory-made chemicals found in popular vitamins. Discover why standard lab test markers can be highly misleading, when targeted supplementation is actually medically necessary, and how to protect your health and budget from aggressive wellness industry marketing.

Dr. Hassell also explores why improving a number on a lab test isn't necessarily the same as improving your health, and why fundamentals such as eating whole foods, exercising, maintaining a healthy weight, and getting outside may matter far more than expensive supplements and testing.

Key Takeaways:

• Most nutritional supplements are synthetic rather than truly "natural."
• Nutrients consumed as part of whole foods come with a complex combination of other compounds that can affect how the body uses them.
• Supplements aren't automatically safe simply because they're labeled as nutritional or natural.
• There are specific situations where supplements can be useful, such as vitamin B12 supplementation for people who cannot absorb B12 properly.
• The evidence supporting many common supplements, including calcium, vitamin D, and antioxidant supplements, is not as strong as supplement marketing may suggest.
• Recommended daily allowances are based on limited nutritional knowledge and don't account for important differences between individuals.
• Be cautious about lab tests that recommend supplements based on a single measurement or biomarker.
• Improving a lab value isn't necessarily the same thing as reducing your risk of dementia, heart disease, diabetes, or cancer.
• Whole, unprocessed foods, regular exercise, maintaining a healthy weight, and spending time outside remain the foundation of good health.
• Consider who profits from the supplements or testing being recommended and whether there is evidence that the intervention actually improves health outcomes.

Can depression and anxiety be improved without relying solely on medication? In this episode of Walk, Don't Run to the Doctor, Miles Hassell MD is joined by clinical psychologist Dr. Traci Rieckmann to explore the growing evidence behind lifestyle medicine for mental health.

Together they discuss why nutrition, exercise, purpose, social connection, sunlight, and reducing screen time may be just as important—if not more effective—for many people than medication alone. Drawing from clinical experience and scientific research, they explain practical steps anyone can begin today to improve mood, reduce anxiety, and build long-term resilience.

Whether you're personally struggling with depression or anxiety, supporting someone who is, or simply looking to improve your overall mental health, this conversation offers practical, evidence-based strategies you can start using immediately.

• Diet and exercise have been shown in multiple clinical studies to significantly improve symptoms of depression and anxiety.
• A Mediterranean-style diet rich in whole foods, fish, vegetables, healthy fats, and fermented foods supports brain health through the gut-brain connection.
• Regular exercise—even just 20–30 minutes per day—can be as effective as antidepressant medications for many people.
• Sunlight, outdoor activity, and social connection play powerful roles in improving mood.
• Small, consistent lifestyle changes are often more sustainable than trying to change everything at once.
• Cooking at home and sharing meals with others improves both physical and mental health.
• Excessive screen time and social isolation can worsen depression and anxiety.
• Finding purpose, helping others, and taking initiative can help break the cycle of low mood.
• Certain medications and underlying medical conditions can contribute to depression and should be evaluated by a healthcare professional.
