Vitamin D (25-OH D) is an essential vitamin that helps regulate calcium and phosphorus in the body and is needed for building and maintaining healthy bones. It plays a critical role in bone and immune health, it helps prevent cancer and protects the body against chronic conditions like depression, type 2 diabetes, heart disease and multiple sclerosis. Because your body can only absorb calcium, the (primary component of bone), when Vitamin D is present. Vitamin D isn’t naturally found in many foods, but your body does make it when direct sunlight converts a chemical in your skin into an active form of the vitamin which is why It is known as the “sunshine vitamin”. 

While rare, high levels of Vitamin D are usually caused by large doses of  Vitamin D supplements - not by diet or sun exposure. The buildup of Vitamin D in your blood can cause nausea, vomiting, weakness and frequent urination.

The amount of Vitamin D your skin makes depends on the time of day, the season, and latitude where you live, which means during the winter months, depending on where you live, your Vitamin D production decreases substantially. On average, during the summer months (after “Spring forward”) the United States see 14-18 hours of daylight, and during the winter months (after “Fall back”) the United States see 6-8 hours of daylight. Shorter days and cold, wet weather often keeps people indoors and exercising less.   50% of the world’s population suffers from insufficient Vitamin D levels, and the reduction in outdoor activities during the winter months is a major contributing factor causing these low Vitamin D levels.

Please prepare to test first thing in the morning. Be sure to drink plenty of water before testing! Being well hydrated will help increase blood flow and improve the testing experience. 

*Note: Do not test on a Friday, Saturday, Sunday, or Holiday. Your sample must be picked up, dropped at a dropbox location or brought to FedEx on the same day you test.
