Studies have shown that low vitamin D levels are a risk factor for cardiovascular disease. Using the data you provided for the GrassrootsHealth Nutrient Research Institute study, we assessed the association between vitamin D level and risk of being diagnosed with hypertension (high blood pressure) among participants aged 50 years and older.
We compared hypertension incidence rates according to vitamin D level. The incidence rate among those with vitamin D levels of 50 ng/ml (125 nmol/L) or higher was 51% lower than the rate among those with vitamin D levels less than 40 ng/ml (100 nmol/L) (P=0.02).
This suggests that increasing vitamin D levels above 40 ng/ml could reduce hypertension risk. While we did not have enough participants in the lower vitamin D level range (less than 20-30 ng/ml) to analyze as its own group, it is likely that the risk reduction would be even higher if we were able to compare the rates in those lower levels.
Are you getting enough vitamin D?
Testing your vitamin D level regularly and taking daily steps to keep it at a target level of 40-60 ng/ml (100-150 nmol/L) is important for all stages of health. Find out your levels today! Log on to the shop (click the link below) to get your tests and see for yourself if your level 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!
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)
