Optimal Vitamin D Test
Discover & Optimize Your Vitamin D Levels
- Test Type: Blood
- 30-Minute Health Coaching Call Included
Vitamin D is essential for healthy bones and teeth, and also helps keep your muscles, nerves, and immune system working properly. Unfortunately, vitamin D deficiencies are very common. Adults are at high risk when they have limited sun exposure, insufficient intake from dietary sources, or impaired intestinal absorption. This test will identify potential vitamin D deficiencies, so you can increase your intake and work toward strengthening your body's immunity, nervous system, and bone health.
What’s Measured
- Complete Vitamin D: Measures D2 and D3 levels and adds them together for a more complete view
- The main role of vitamin D is to help regulate blood levels of calcium, phosphorus, and magnesium.
- Vitamin D is vital for the growth and health of bone; without it, bones would be soft and unable to repair themselves normally.
- Vitamin D has also been shown to support other tissues as well as regulate the immune system.
- Vitamin D2: Found in plant-based foods like mushrooms, fortified foods, and as a dietary supplement
- Vitamin D2 is the inactive form of D and is a fat-soluble vitamin that is naturally found in some plants and in fortified cereals and that helps your body absorb calcium and phosphorus, which are important for building and keeping strong bones, and preventing bone disorders.
- Vitamin D3: Found in animal-sourced foods like fish oil, eggs, and butter
- Lasting longer in the body than D2, it is naturally found in animals and is produced by the skin when it's exposed to sunlight.
Who Is It For
- Adults who want an objective measure of their vitamin D status, including D2 and D3.
- Anyone with limited sun exposure or limited dietary sources of vitamin D who wants a baseline.
- Anyone who takes a vitamin D supplement and wants to confirm that it is enough.
- Clients working with an EquiLife health coach or Integrative Health Practitioner who want a baseline and a point to retest from.
- Customers in the United States (except New York and Washington), Australia, Canada, New Zealand and the United Kingdom.
