Episode 52. Vitamin D Is Not a Vitamin: Light, Immunity, Mood, and Why Supplements Often Fail

0:00 27:28

Did you know that vitamin D isn’t really a vitamin at all; and the real issue isn’t how much you supplement, but how much light your body receives?

In this episode of the Vital Spirit Podcast, I explore the deeper physiology of vitamin D and why thinking of it as just another nutrient misses the bigger picture. Vitamin D functions as a hormone that communicates information about light, safety, season, and rhythm to the body. That means when levels stay low despite supplementation, the real question often isn’t “How much should I take?” but rather “What upstream signal is missing?”

If your vitamin D levels have ever stayed stubbornly low or you’ve wondered whether supplements are really enough, this episode will help you understand the bigger biological story.

In this episode, we cover:

• 03:32 Why vitamin D is technically not a vitamin • 04:54 Vitamin D’s role in gene regulation and nutrigenomics • 06:17 I explore the connection between vitamin D and immune regulation • 09:08 How the skin functions as an immune and endocrine organ • 10:03 The relationship between vitamin D, mood, circadian rhythm, and serotonin production, including how low levels can contribute to depression • 12:58 Why vitamin D becomes even more important in midlife • 13:49 The common reasons vitamin D levels remain low even with supplementation • 15:37 Which labs actually matter when evaluating vitamin D status • 17:12 Practical strategies for raising vitamin D • 25:28 I share my frustration about insurance companies increasingly refusing to cover vitamin D testing and why this matters for preventive medicine
