Vitamin D*action Test Kit for Consumer-Sponsored Research Participation

Did you know that 9 out of 10 Americans may be deficient in vitamin D and not even know it?

As a courtesy and convenience to our customers who wish to gain knowledge about their vitamin D levels, is offering for sale a third-party vitamin D test kit (developed and offered by GrassrootsHealth) designed for participation in a consumer-sponsored project to gather information on vitamin D levels in the population (The D*action project). We do not make any profit on the sale of this third-party test kit; we offer it solely as a convenience to our customers.

Unfortunately, many people are deficient in vitamin D because they aren’t able to obtain enough of the vitamin through direct sunlight and their diet alone.

The only way to know for sure if you are vitamin D deficient is to regularly test your blood levels, which you can do with this at-home test kit developed and offered by GrassrootsHealth as an integral part of their D*action consumer-sponsored project.

The D*action project is the world’s largest project that collects data through the active involvement of its participants. When you order your kit, you will be participating in this project and study.

Simply follow the directions in the kit to collect a small blood sample, mail it in, and fill out a quick and easy online health questionnaire through GrassrootsHealth (which will take you 5 to 10 minutes to complete).

Your participation and sharing your results enables researchers to inform the public about the status of vitamin D in the population. Plus, you get to be a part of this crucial initiative to put a stop to vitamin D deficiency.

After filling out the questionnaire, you will receive an email when your test results are ready. This is usually within 7 to 10 days after receipt of your sample. Please note that does not play any role in the analysis of the sample, interpretation of the test results, or in the collection of data by the D*action project.

That said, testing allows you to gain valuable knowledge about your vitamin D levels, and the feedback you provide to GrassrootsHealth allows them to make discoveries about vitamin D and spread the word to millions around the globe.
