Can Vitamin D Deficiency Cause Fatigue, Illness, or Mood Swings?

Discover the Symptoms, Risks, and the Best D3 Supplement to Restore Your Health

Why Vitamin D Is More Than Just a “Sunshine Vitamin”

Vitamin D plays a critical role in bone health, immune defense, and mental clarity. Yet millions of people—especially those in colder climates or with indoor lifestyles—are unknowingly deficient. This silent epidemic can lead to:

·         Chronic fatigue

·         Frequent colds and infections

·         Mood disorders like depression

·         Muscle weakness and bone pain

Who’s Most at Risk?

If you fall into any of these categories, you may be at higher risk:

·         Office workers with limited sun exposure

·         Older adults with reduced skin synthesis

·         People with darker skin tones (melanin reduces vitamin D production)

·         Vegans or vegetarians with limited dietary sources
