Is Vitamin D 9 low, normal or dangerous? What does Vitamin D level 9 mean?

📅 Medical Review Date: December 13, 2025

Your Vitamin D level of 9 is a Low Vitamin D level.

A vitamin D level of 9 nmol/L usually means the body has low vitamin D stores. It suggests vitamin D deficiency. Low levels of vitamin D can cause bone pain, muscle weakness, fatigue, frequent infections, hair loss, depression, and increased fracture risk. This can be caused by lack of sun exposure, poor diet, malabsorption, or kidney disease. Further tests are often needed to identify the cause and guide appropriate treatment.

Low Vitamin D levels may indicate underlying health problems. The normal range is typically between 75 nmol/L and 250 nmol/L. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal Vitamin D range for men is :75 - 250 nmol/L
