For years, a great misconception has clouded our understanding of Vitamin D. A renowned physician is here to correct the record, explaining why thinking of it as just a “vitamin” for bones is a major error that could be impacting your health.
The first correction is its identity: it is a potent steroid hormone. This is not a minor detail; it’s the key to understanding its vast influence over more than 200 genes that regulate everything from your immune system to your mood.
The second correction concerns its source. The misconception is that a healthy diet is enough. The expert clarifies that this is false; food provides only a tiny fraction of what we need. Our primary source is, and always has been, production in the skin via sunlight.
The third correction relates to deficiency. The common belief is that it’s rare or has obvious symptoms. In reality, it is extremely common, and its signs—fatigue, low mood—are so subtle they are often missed for years.
The final, and most important, correction is the solution. Forget trying to eat “piles” of fish. The corrected approach, recommended by the physician, is to get 10 to 30 minutes of midday sun exposure daily. This is the simplest and most effective way to align with our biology.
