High Vitamin D3 LevelsUpdated 24 days ago

Dr. Berg recommends that optimal Vitamin D3 levels are between 60 and 80 ng/mL. He has mentioned that his personal levels are often over 100 ng/mL to help with his old injuries and arthritis. To manage this, he regularly tests his blood calcium levels. This is important because high doses of Vitamin D can increase calcium absorption, so monitoring helps ensure those levels stay within a healthy range.
