INSIGHT

Prevalence of Vitamin D Deficiency

Up to 80% of Americans have insufficient vitamin D, linked to many diseases.
Optimal vitamin D levels are much higher than standard lab references suggest.

ADVICE

Safe Sun Exposure Tips

Get 20 minutes of full body sun exposure daily between 10 a.m. and 2 p.m. when possible.
Use safe sunscreen on the face and protect skin to balance vitamin D and skin cancer risk.

INSIGHT

Magnesium's Crucial Role

Magnesium is essential for over 600 enzymatic reactions affecting every body system.
Deficiency is common and linked to wide-ranging symptoms beyond just cramps.

Up to 80% of people may be living with insufficient levels of vitamin D, magnesium, and omega-3 fatty acids—three essential nutrients involved in critical functions like immune defense, cardiovascular health, mood regulation, and brain function. Modern lifestyles—marked by nutrient-poor diets, low sun exposure, chronic stress, and overuse of medications—disrupt the body’s ability to absorb and maintain these key nutrients. Deficiencies often go undiagnosed due to outdated testing, yet they’re strongly linked to conditions like depression, fatigue, diabetes, and heart disease.

In this episode, I talk about, along with Andrew Huberman, how modern lifestyles and diets lead to widespread nutrient deficiencies and chronic disease—and how targeted nutrition and lifestyle changes can restore optimal health.

Dr. Andrew Huberman is a neuroscientist and tenured Professor in the Department of Neurobiology at the Stanford University School of Medicine. He has made numerous important contributions to the fields of brain development, brain function, and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills, and cognitive functioning. Dr. Huberman is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award in 2017, which is given to the scientist making the largest discoveries in the study of vision. His lab’s most recent work focuses on the influence of vision and respiration on human performance and brain states such as fear and courage. Work from the Huberman Laboratory at Stanford University School of Medicine has been published in top journals including Nature, Science, and Cell and has been featured in TIME, BBC, Scientific American, Discover, and other top media outlets.
