Vitamin D, B12, and Folate are the three most commonly deficient vitamins in the US population. Vitamin D deficiency affects an estimated 42% of American adults and is linked to fatigue, bone loss, depression, and weakened immunity. B12 deficiency causes neurological symptoms, anemia, and cognitive decline — especially in older adults and those on plant-based diets. Folate (B9) is essential for DNA synthesis, red blood cell formation, and is critical during pregnancy. This panel provides a quick, affordable screen for the three most impactful vitamin deficiencies. For a more comprehensive assessment including minerals, consider our Vitamin & Mineral Panel.
