Screen for low levels of Vitamin D so you can treat it with supplements before it causes health problems
Vitamin D is a cornerstone of good health. Unfortunately, about 42% of the US population is considered deficient in Vitamin D. But wait, there’s more. Vitamin D isn’t just critical for adults, but especially children. About 1 in 10 kids in the US are also deficient in Vitamin D, and as many as 60% could have “suboptimal levels.”
From the comfort of home, you can easily screen and monitor the body’s level of Vitamin D. This at-home lab test classifies your Total Vitamin D into one of four categories – target optimum supply levels to maintain abundant energy, vitality and well-being.

What is Vitamin D?
Let’s learn some science! Vitamin D is a fat-soluble vitamin that helps absorb calcium and phosphorous minerals. This characteristic plays a vital role in forming and maintaining strong bones and teeth, regulating normal immune system function, maintaining heart and lung health, and combating depression and other diseases. While produced by exposure to the sun, natural and fortified foods also contain Vitamin D.
Vitamin D is a nutrient your body needs for building and maintaining healthy bones. That’s because your body can only absorb calcium, the primary component of bone when Vitamin D is present. Vitamin D also regulates many other cellular functions in your body. Its anti-inflammatory, antioxidant, and neuroprotective properties support immune health, muscle function, and brain cell activity.
Some foods containing Vitamin D include fortified milk, fortified cereal, and fatty fish such as salmon, mackerel, and sardines. Your body also makes Vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol).
The amount of vitamin D your skin makes depends on many factors, including the season, latitude, and skin pigmentation. Depending on where you live and your lifestyle, Vitamin D production might decrease or be completely absent during the winter months. Sunscreen, while helpful in preventing skin cancer, also can reduce Vitamin D production.
What will my test results show me?
Your results will tell you the concentrations of Vitamin D2 (found in some foods & supplements), D3 (derived from solar radiation & supplements), and Total 25-Hydroxy vitamin D (the sum of D2 + D3).
The reference ranges for your Vitamin D 25-Hydroxy test is quantified and categorized as the following:
- Deficient: (< 15 ng/mL)
- Insufficient: (15 to < 23 ng/mL)
- Optimum: (23 to 75 ng/mL)
- Potential Toxicity: (> 75 ng/mL)
Please note: The above reference ranges are for guidance only and are not a diagnosis. Although a result above 75 is typically considered elevated, multiple studies show Vitamin D toxicity is rare and usually only presents with a level greater than 125 ng/mL. Every patient has a unique medical history and symptoms. You should talk to your physician if your Vitamin D test results indicate a deficiency or elevation to determine your optimum Vitamin D concentration.
