Vitamin D & Omega-3 Test Kit for Consumer-Sponsored Research Participation

Vitamin D and omega-3 fatty acids are two of the most important nutrients your body needs to maintain optimal health. However, you can’t tell by looking in a mirror if you are deficient in vitamin D or omega-3s. The only real way to know if you are deficient in these nutrients is to get tested.

We are now offering a combined test kit that analyzes vitamin D and omega-3 levels. This third-party test kit is part of a consumer-sponsored research project directed by GrassrootsHealth, aimed to gather information on the population’s vitamin D and omega-3 levels to better understand these nutrients and their deficiencies. It’s the largest project in the world that helps inform the public about their vitamin D and omega-3 nutritional status and allows scientific researchers to study the links between these nutrients.

As a contributor to this research, you get to learn your own vitamin D and omega-3 index levels. This will help you make better decisions about your health and nutrition. It’s a win-win for all — test your blood now, contribute to this important research, learn your levels, take corrective action, and then test again in 3 to 6 months to see how your levels have changed.

The omega-3 Index is a measure of the omega-3s in your red blood cells and is the best way to measure your omega-3 levels, since the fatty acids are found in red blood cell membranes. It is in the cell membranes where the omega-3 fatty acids (DHA and EPA) do all their work. Find out where your levels are by participating in this project and study today!

Simply follow the directions in the kit to collect the small blood samples, 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 and omega-3 in the population. Plus, you get to be a part of this crucial initiative to put a stop to vitamin D and omega-3 deficiencies.

After filling out the questionnaire, you will receive an email when your test results are ready. This is usually within 10 to 20 days after receipt of your sample.

  • 2 blood spot cards
  • 1 envelope for returning the card
  • 1 gauze pad, 2 band aids, and 1 alcohol swab
