In earlier posts we explored the relationship between vitamin D level, Omega-3 Index, and vitamin C intake and the occurrence of colds and the flu separately. In the final blog post of this series, using the data you provided for the GrassrootsHealth study, we’ll explore whether vitamin D, omega-3, and vitamin C have a combined effect on colds and the flu.

For vitamin D alone, the percent of participants who experienced the flu in the prior 6 months was 32% lower for those with a vitamin D level at or above 40 ng/ml (100 nmol/L) compared to those with a level below 40 ng/ml (P<0.00001). For colds, it was 11% lower (P=0.00001).

For omega-3 alone, the percent of participants who experienced the flu in the prior 6 months was 38% lower for those with an Omega-3 Index at or above 8% compared to those with an Index below 8% (P=0.09). For colds, it was also 11% lower (P=0.26).

For vitamin C alone, the percent of participants who experienced the flu in the prior 6 months was also 32% lower for those who reported that they usually took supplemental vitamin C compared to those who did not (P=0.009). For colds, it was 9% lower (P=0.14).

For vitamin D, omega-3, and vitamin C combined, the percent of participants who experienced the flu in the prior 6 months was 72% lower for those with a vitamin D level at or above 40 ng/ml who also had an Omega-3 Index at or above 8% and also reported that they usually took supplemental vitamin C compared to those with a vitamin D level less than 40 ng/ml and an Omega-3 Index below 8% who did not report usually taking supplemental vitamin C (P=0.005). For colds, it was 21% lower (P=0.17).

This preliminary analysis suggests that the combined effect of maintaining a vitamin D level of at least 40 ng/ml, an Omega-3 Index of at least 8%, and taking supplemental vitamin C could provide greater risk reduction for colds and the flu than relying on one of these nutrients alone. Further analysis is needed to assess this association by adjusting for other biometric and lifestyle risk factors. These analyses of individual and combined nutrient effects from GrassrootsHealth are possible because YOU provide us with data on multiple nutrients and health outcomes.

Test to know your status of these essential nutrients to help protect you from the cold and flu

Make sure you know your vitamin D level, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level. Find out your levels today! Log on to the test selection page (click the link below) to get your tests and see for yourself if your levels can be improved.

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

How can I track my nutrient intake and levels over time?

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!

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)?

Did you know your health could be greatly affected by making sure you have a vitamin D level of at least 40 ng/ml (100 nmol/L)? Help us help you.

STEP 1 - Do you know what your vitamin D level is? If not, be sure to test today to find out.

STEP 2 – Determine your target level. Are you at your target level? Experts recommend a level of at least 40-60 ng/ml (100-150 nmol/L).

STEP 3 – Need to boost your level? Use the D*calculator to see how much vitamin D it may take to reach your target. Opt for the Loading Dose for a quicker boost.

STEP 4 – Optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.

STEP 5 – Re-Test! This is an important step to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-4 months is recommended.

STEP 6 – Adjust, Repeat…

Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases, especially COVID-19.

NEWS ALERT

The first Randomized Controlled Trial on vitamin D and COVID-19 has shown a 96% lower risk of ICU admission for those receiving vitamin D (as 25(OH)D to quickly boost vitamin D blood levels) along with the standard treatment, compared to those receiving standard treatment alone.

These results support many previous observational studies showing a relationship between vitamin D levels and intake and COVID-19 severity.

Review the Latest Nutrient Research for COVID-19

GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that nearly 15,000 people are already using for their health. Specific markers that influence immune health are suggested for testing as part of this project including:

  • Vitamin D
  • Omega-3 Index
  • Essential elements magnesium, selenium, and zinc
  • hsCRP

Our goal is to demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to show the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction for all ethnicities in the population. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. Join the project today!
