Item Catalog Number: LC081950
Recent research has shown that vitamin D is important to every cell and tissue throughout the body. From proper immune function and bone density to heart health and mood disorders, vitamin D is critical for optimal health.
You should know your Vitamin D blood level. Life Extension offers a reliable vitamin D blood test at a fraction of what most commercial blood labs charge. Optimal blood levels of vitamin D are often far greater than the standard reference range. The only way to achieve an optimal level is through proper supplementation.
Fasting is not required for this blood test. Take all medications as prescribed, but do not take your supplements the morning of the test. This test is also included in the Lichten comprehensive thyroid panel.
