82% of GrassrootsHealth participants have an Omega-3 Index level below the recommended 8%

Healthy Omega-3 levels have been associated with heart health, a longer life, brain health, breast cancer, reduced inflammation, and even an improved immune response to viral infection. Unfortunately, due to the Western diet, a majority of the population has omega-3 levels that are below what is recommended for health. What can you do to make sure you are getting enough?

How is omega-3 status measured?

First, it is important to understand how omega-3 levels are measured in the body. In order to combine and compare data from multiple studies that used different omega-3 measurements to evaluate its status, a study by Stark et al. considered multiple sample types (e.g., plasma, serum, whole blood, red blood cells, etc.) and different fatty acid measurements (e.g., EPA+DHA+DPA) that have been used to determine the overall omega-3 status around the globe. Since the use of different metrics makes combining and comparing data from multiple studies difficult, the authors weighted the benefits of each and concluded, “In order to compare the omega-3 polyunsaturated fatty acid (PUFA) status across the globe, EPA+DHA in erythrocytes [the Omega-3 Index] was selected over other omega-3 PUFA blood biomarkers, as it has been well defined in the literature previously.”

This identified the Omega-3 Index as their biomarker of choice for defining omega-3 status. It is a measurement of the amount of EPA and DHA in red blood cell (RBC) membranes, and it reflects long-term (about four months) intake of EPA and DHA from food and supplements.

What is your Omega-3 Index level?

The optimal range for the Omega-3 Index is suggested to be 8% or more. Less than 4% is undesirable, and 4-8% is in the intermediate risk zone. The majority of the US and Canadian populations are around 4%, while Japanese are typically above 8% due to the amount of fresh fish in their daily diet.

Since mid-2017, GrassrootsHealth has offered a home blood spot test for the Omega-3 Index.  Among the 2,777 participants who had tested their Omega-3 Index as of July 2020, the average index was 5.7%. Almost one-fifth (18%) of participants had an Omega-3 Index of 8% or higher; 27% had an index between 6.0% and 7.9%, 45% had an index between 4.0% and 5.9%, and 10% had an index less than 4%.

Additionally, among those who completed two or more tests, 71% of those with an Omega-3 Index less than 8% increased their index after their first test. This indicates that when individuals are provided with information about their health, they are empowered to make changes and to take charge of their own health.

How can you improve your Omega-3 Index?

After you test and receive your Omega-3 Index results, we encourage you to use the Omega-3 Calculator to determine an estimated amount of how much more EPA+DHA you will need to reach 8% (or other desired goal). EPA+DHA is found in fish and many omega-3 supplements, but be sure you check how much EPA+DHA is in the specific types of fish you eat and the omega-3 supplements you take to determine how much of each you may need to consume.

While studies have shown that it is possible to achieve a higher Omega-3 Index through diet alone, it may be difficult to reach the recommended level of 8% or higher without supplementation.

How do you know if your changes are helping?

Make a change, then test again! Experts agree it takes at least 3-4 months for the change in blood levels to normalize after a change in intake/routine. Depending on how drastic a change you are trying to achieve, re-testing in 3-6 months is suggested. It may take a few test cycles to get your omega-3 (and D) regimen where you want it, and measurement is key.

Are You Getting Enough Omega-3s?

The Omega-3 Index is the key measurement to determine your level of omega-3 fatty acids in the body. Along with the Omega-6:Omega-3 Ratio and the AA:EPA Ratio tests, you can get a clear picture of your omega fatty acid status. Are you getting enough omega-3s to support your healthy immune and inflammatory response? Test to find out!

What does the Research Say about Vitamin D & COVID-19?

It’s TIME to start saving lives! If you can help PREVENT the majority of the death, it’s time! What’s it costing you/us not to take action NOW?

There is much published research that supports a clear link between vitamin D and COVID-19 showing that higher vitamin D levels are related to:

a decreased risk of testing positive for COVID-19

increased viral SARS-CoV-2 RNA clearance

better clinical outcomes among patients with COVID-19

less severe COVID-19 disease

decreased risk of death due to COVID-19

Be sure to educate yourself on the benefits and importance of vitamin D for immune health, and take steps to ensure you and your loved ones are getting enough.

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!
