Fatigue affecting life for 3 months. can a vitamin d level of 20 cause fatigue and depression? if so, can supplementing it with 2,000 iu daily help?

Vitamin D3: Fatigue and depression can be related to low vitamin D3. At a level of 20, 2K IUs sounds low. Please check w/your doc but many people use 5K daily. Peace and good health.
