Are probiotics important for vitamin D levels?

Published on August 25, 2020

Probiotics aid digestion, improve the absorption of nutrients, and help keep balance in the gut microbiome. A recent study by Bosman et al. showed a link between the amount of beneficial bacteria in the gut and individuals supplementing with vitamin D or receiving UVB exposure. Some studies have also demonstrated that probiotics are effective at improving vitamin D absorption and increasing expression of the vitamin D receptor (VDR). In today’s blog we will investigate whether supplemental probiotic intake affects vitamin D levels among GrassrootsHealth participants.

Supplemental Probiotics Intake and Vitamin D Dose-Response among GrassrootsHealth Participants

Using the data provided for the GrassrootsHealth study from over 3,500 participants with supplemental probiotic information, we plotted every participant’s supplemental vitamin D intake (dose) and blood level (response) and determined the average trends for participants who reported taking supplemental probiotics and those who reported taking no supplemental probiotics.

This preliminary analysis shows that on average, those taking supplemental probiotics have a higher vitamin D level for any given vitamin D intake amount than those not taking supplemental probiotics. Specifically, 72% more supplemental vitamin D was needed for 50% of the population to achieve 40 ng/ml (100 nmol/L) for those did not take probiotics compared to those who did.

Protect Your Immune Health by Avoiding Vitamin D Deficiency!

Your vitamin D level matters! In fact, one study showed an almost 60% increased risk in COVID-19 infection for individuals whose vitamin D level was below 30 ng/ml (75 nmol/L) compared to individuals whose vitamin D level was 30 ng/ml or higher. The same study also found that among the COVID-19 positive individuals, there was an almost doubled risk of hospitalization for those whose vitamin D levels were below 30 ng/ml. Ensure your vitamin D and other nutrient levels are within range! Help support a healthy immune system and more by testing today to find out your level of vitamin D and other nutrients important for a healthy immune response.

Are You Getting Enough Vitamin D to Help Yourself?

We’re in a time of great crisis that could be greatly affected by making sure you and everyone you know has a serum level of at least 40 ng/ml. Help us help you.

Do you know what your vitamin D level is? Be sure to test today to find out, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases.

GrassrootsHealth Nutrient Research Institute is preparing to do a Community RCT with the use of our myData-myAnswers nutrient health system that over 15,000 people are already using for their health. We will demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to establish the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction with different ethnicities in the population.

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

To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called

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)
