A breakdown of key essential nutrient levels and actionable follow-up steps

Many people have a vitamin deficiency that affects their overall quality of life. Vitamin deficiencies can cause numerous issues including hair loss, weak bones, anemia, as well as long-lasting feelings of fatigue due to disproportionate mineral levels. True Marker’s at-home vitamin deficiency test is a valuable health monitoring tool. This essential vitamin test measures your vitamin D, B12, and B9 levels—all of which are important indicators of potential health issues.

There are different ways to measure vitamin levels. Here’s why they matter for you:

Vitamin D

Vitamin D has been linked to hair loss alongside certain autoimmune disorders, as well as alopecia. The FDA believes that Vitamin D is essential for hair growth and maintenance of the hair follicle.

Vitamin B9 (Folate)

Folate, or Vitamin B9, is important in creating new red and white blood cells in the blood. Folate or folic acid has also been shown to help in creating DNA and RNA as well aiding in the rapid growth of cells during infancy, adolescence, and pregnancy.

Vitamin B12

Vitamin B12 is important for neurological function, creating DNA, and creating red blood cells to aid in oxygen transport throughout the body. It is also an essential nutrient in pregnancy.
