This test measures the levels of 12 essential micronutrients in your blood, including three vitamins (vitamin D, vitamin B12 and folate).  Empower yourself with insights into your diet so you can make informed decisions about your nutrition and performance. Symptoms like fatigue, weight loss or lack of appetite may be related to inadequate nutrition and can go unnoticed. However, symptoms of vitamin and mineral deficiency are often vague and could be signs of other health problems. Testing your micronutrient levels can uncover opportunities to optimize nutritional status.  If you are experiencing concerning symptoms, you should connect with a healthcare provider for guidance.
