The Toxins Behind Heart Disease: What Your Doctor Isn’t Testing For with Dr. Christopher Davis

Dr. Christopher Davis, triple board-certified cardiologist and functional medicine expert, reveals why the real root of heart disease isn’t cholesterol—it’s toxins, inflammation, and oxidative stress.

At Reveal Vitality, he now helps patients uncover toxins, reduce inflammation, and prevent heart attacks. In this episode, we break down why toxins are showing up in almost every patient, the surprising link between saunas and detoxification, and how women in their 30s and 40s can catch early heart disease warning signs long before standard testing would.
