Vitamin D has emerged as a crucial nutrient for many different aspects of health. There are vitamin D receptors on almost every cell in the human body. Insufficient vitamin D levels are associated with diabetes, cardiovascular disease, depression, autoimmune diseases, and several cancers.

Since vitamin D is scarce in foods and getting adequate sun exposure without increasing skin cancer risk is difficult, Dr. Fuhrman recommends supplementation. Vitamin D requirements are not the same for everyone, and supplementation should aim to keep blood vitamin D levels within the optimal range of 30-50 ng/ml. Testing vitamin D levels at home can guide supplementation to achieve a vitamin D level in this optimal range, without the inconvenience of doctor visits and blood draws.

ZRT Laboratory’s Blood Spot Vitamin D test allows you to test your vitamin D levels at home with a simple finger stick; the blood is simply dried on a piece of filter paper and shipped to the laboratory. Blood Spot testing provides results on par with those from regular serum tests.
