Vitamin D Testing Now Available at InOut Labs

InOut Labs is now offering vitamin D testing that can be done without a doctor visit. Owner Tim Thoelecke Jr. says, “You can get vitamin D from the sun, but in a northern climate, you would need to spend a lot of time outside in the middle of the day with no sunscreen and lots of skin exposed. Darker skin needs more time than lighter skin. Very few get this kind of sun exposure, so we take supplements.”

Vitamin D affects many of the body’s critical functions and studies suggest at least 64 percent of Americans are deficient, which can contribute to Type 2 diabetes, infection, cardiovascular disease, autoimmune disease, neurological disease, low testosterone and even cancer. However, too much Vitamin D can be toxic, so supplementation should be monitored.

InOut Labs offers more than 700 types of tests, including background checks and employment drug, DNA paternity, STD and HIV, alcohol and wellness tests.
