#20 Vitamin D: Your Brain’s Hidden Hormone

What if the problem isn’t your willpower, your schedule, or even your thyroid—but a brain running on low vitamin D? We reframe “the sunshine vitamin” as a true brain hormone and unpack why living at a “normal” 32 rarely restores mood, focus, or sleep. Drawing on real stories—hot flashes gone in weeks, anxiety quieted, hair shedding slowed, and even fertility surprises—we connect the dots between vitamin D, neurochemistry, and the kind of steady energy that makes you feel like yourself again.

We also dig into how vitamin D activates the enzymes that produce serotonin, dopamine, and GABA, how it protects brain cells. Then I share my powerful 3 month vitamin D protocol (with a twist on why).

For listeners ready to personalize further, we share how a brain-focused DNA test can map neurotransmitter pathways and guide diet, training, and recovery choices that match your nervous system state.
