Frequently asked questions
Why is it important to test Vitamin D levels?
Your Vitamin D levels are influenced by sun exposure, diet, and supplementation. Because many regions experience low sunlight for half the year, levels can drop significantly during the winter months. Testing helps you determine if you are maintaining a healthy range or if you are at risk for deficiency.
What are the symptoms of Vitamin D deficiency?
Common signs of low Vitamin D include frequent infections or illnesses, persistent fatigue, bone and back pain, muscle weakness, and a low mood. However, many people with a deficiency may not experience any obvious symptoms until bone health is already compromised.
How does it work? / When do I get my results?
