    Product Description

    This kit tests for the levels of Vitamin D in your body.

    Vitamin D is involved in the regulation of many cellular functions in your body that include supporting a healthy immune system, muscles, and brain cell activity. Your body also needs this vital nutrient to build and maintain healthy bones, as it helps regulate the amount of calcium and phosphate in the body.

    This at-home lab test can be used to ensure you have adequate levels of Vitamin D to promote a healthy immune system, bones, and cellular health.



    Vitamin D is produced in the skin upon absorption of sunlight. Vitamin D is essential for healthy bones and a strong immune system. Low levels of Vitamin D are associated with a myriad of health problems, including inflammation. Vitamin D deficiency is curable by spending more time in the sun, consuming foods rich in Vitamin D, or through supplementation.
