Vitamin D has been praised, dismissed, and debated—but the truth lives somewhere in the middle.
In this episode of Healthy Looks Great on You, Dr. Vickie breaks down what vitamin D actually does in your body, why deficiency is so common (even among sun lovers), and why supplementation should be personalized rather than automatic.
You’ll learn how vitamin D functions not just as a vitamin, but more like a hormone—affecting bone strength, immune function, muscle health, mood, and even cardiovascular risk. We explore how sunlight, skin tone, diet, and lifestyle influence vitamin D levels, why “more is better” can be harmful, and what emerging research suggests about optimal blood levels.
This episode also covers:
-
Signs and symptoms of vitamin D deficiency
-
Food sources (including the only plant-based option)
-
Vitamin D3 vs D2—what’s the difference?
-
Safe, evidence-based dosing strategies
-
Why blood testing matters before and during supplementation
If you’re navigating midlife health, fatigue, low energy, frequent infections, or simply trying to age well without falling for supplement hype, this episode will help you make a smarter, individualized decision.
Because when it comes to supplements, science matters—and healthy looks great on you.
