Vitamin D and omega-3 fatty acids have been shown to boost the immune system. Using the data you provided for the GrassrootsHealth study, we assessed the combined effect of vitamin D and omega-3 nutrient status on the occurrence of colds.

We found that the percent of participants who experienced a cold in the prior 6 months was lowest for those with both a higher vitamin D and Omega-3 status (vitamin D levels at or above 40 and Omega-3 Index at or above 6%) compared to those with just a higher vitamin D status, just a higher Omega-3 status, or a lower status for both. Specifically, the occurrence of colds was 28% lower among participants with higher vitamin D and omega-3 status compared to participants with lower vitamin D and omega-3 status.

This suggests that improving both vitamin D and omega-3 status could provide greater risk reduction for colds than either nutrient alone.

Are you getting enough vitamin D and omega-3s?

To know if you are getting enough of these nutrients, make sure you know your Omega-3 Index, and test your level of vitamin D! Testing these levels and taking daily steps to keep your Omega-3 Index at a target of at least 8%, and your vitamin D at a target level of 40-60 ng/ml (100-150 nmol/L), is important for all stages of health.

Make sure you track your results before and after, about every 6 months!

How can I track my nutrient intake and levels?

To help you track your supplement use and nutrient levels, GrassrootsHealth has created an online tracking system called myData-myAnswers. For each specific supplement, you can track what days you take it, how much, and many other details. This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels. Check it out today!

How Can You Use this Information for YOUR Health?

Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!

STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health

STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study

STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there

STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
