Magnesium*PLUS Focus Project Enrollment

Participant registration – Welcome from GrassrootsHealth Nutrient Research Institute and Dr. Guarneri!

Join the Magnesium*PLUS Focus Project for you, for anyone who wants to know how their magnesium, omega-3, and vitamin D intake and supplements are working for them.

How can you benefit from taking any/all of these nutrients? Key information will be gathered from each participant about their levels of each of these nutrients via home blood spot tests —the magnesium red blood cell (RBC) test, the Omega-3 Index, and the Vitamin D (25(OH)D) serum test. In addition to the tests, information about your health will be gathered through the online questionnaire, and optional targets/goals can be added with the myTrackers feature in the software.

A special set of tracking questions have been created by Dr. Guarneri to help you track the aspects of your health that are most important to magnesium intake.  Entering data into these trackers regularly can help answer questions about your supplementation, the product you are using, how often you are taking it, and how it is affecting you.

It is with these measurements, from both the blood measures and your health information, that the GrassrootsHealth Nutrient Research Institute can put the power of its demonstrated science and methodology behind the information for you.

What are my nutrient levels? How are they affecting me?

How do they seem to be associated with any various health outcomes in the total group (over 15,000) from pain to asthma to preterm births to risks of various cancers and other conditions?

How do my levels and health outcomes compare with others?

What do other nutrient researchers recommend?

What is participation?

  1. Enroll in the project at the link below. This project has two blood spot tests that can either be done at home with a blood spot test kit, or in the office with your other tests. There is a lab fee of $185 which is part of the enrollment.
  2. Answer the health questionnaire and then bring your payment confirmation email and participant ID into your next appointment at the Guarneri office if doing the in-office test.  **Both the payment of the lab fee and questionnaire are to be done for each participant separately (e.g., parents, children).**
  3. After your blood spot cards have been completed, please send them in to GrassrootsHealth (addressed envelope provided).
  4. You will get your result notification by email within 7-10 days after GrassrootsHealth’ receipt of the cards and questionnaire.
  5. Look to see if you have achieved the recommended range of 40-60 ng/ml for D, >8% for the Omega-3 Index
  6. Use the calculators linked from your results pages to help you determine what adjustments you might need to make to achieve those levels.
  7. Retest in 6 months to make sure you have reached your target levels!

We are expecting to show a new ‘dose-response’ curve for several key magnesium compounds (each will be different based in part on their absorption capabilities) so we can more specifically correlate the information with various health outcomes—this will be a first in this industry and a great benefit to your health to enable you to more quickly target your outcomes with specific doses/actions. We will also analyze the magnesium values with the vitamin D and omega-3 values so we can share how they might support each other—again, to enable your own health decisions.

** Enrollment in this special project includes your authorization for GrassrootsHealth to share your questionnaire data and nutrient results with the health office of Dr. Guarneri.

If you have previously received vitamin D results in the D*action project, please log in here.  Otherwise, if you are a new participant
