How do you know if you’re Vitamin D deficient? ☀️
Most people think Vitamin D deficiency only happens in cold, cloudy places…
But even in California, an estimated 70–80% of people are below optimal levels.
Here are 3 common signs your body may be craving more sunlight:
1. Constant fatigue
If you feel tired no matter how much you sleep, low Vitamin D could be affecting your cellular energy and mitochondrial function.
2. Getting sick often
Vitamin D plays a major role in immune health. Frequent colds, low resilience, or slow recovery can all be signs your levels are low.
3. Low mood or feeling “off”
Vitamin D is deeply connected to mood, brain health, and circadian rhythm. Many people notice increased anxiety, low motivation, or seasonal mood changes when levels drop.
Modern life keeps us indoors under artificial light far more than our biology was designed for.
Sometimes the body isn’t asking for more stimulation…
It’s asking for more light. 🌿
