The Natural Marketing Institute (NMI) recently released its 2019 Consumer Trends Report which is a comprehensive analysis of the dietary supplement market from the consumer perspective. The report identified four important market trends for today’s consumers: 1) proof of effectiveness, 2) tangible value, 3) emerging attributes such as sustainability and organic ingredients, and 4) control of their own health with natural supplements that address underlying issues.

GrassrootsHealth is uniquely designed to contribute to three key consumer needs (we don’t currently capture information on organic ingredients). With our initial focus on vitamin D, we have been able to use the data you provided on blood tests and questionnaires to demonstrate the tangible benefits and degree of effectiveness of having a vitamin D level of at least 40 ng/ml (100 nmol/L). Below are some of our key findings for vitamin D and health using YOUR data. Also, our method of providing nutrient status testing results and evidence-based information about target nutrient levels allows participants to take ownership over their health.

All Cancers Combined

In this analysis, data from GrassrootsHealth was pooled with data from a randomized controlled trial conducted by Dr. Joan Lappe, a scientist from GrassrootsHealth’s panel of vitamin D experts. This pooled cohort had improved statistical power due to the larger sample size and provided a broader range of vitamin D levels than either cohort alone. We found that among women aged 55 years and older, those with vitamin D levels at or above 40 ng/ml had a 67% lower risk of cancer than those with levels less than 20 ng/ml (P=0.03), adjusted for age, BMI, smoking status, and calcium supplement intake.

Breast Cancer

This analysis also used pooled data from GrassrootsHealth and two randomized controlled trials by Dr. Joan Lappe. We found that among women aged 55 years and older, those with vitamin D levels at or above 60 ng/ml (150 nmol/L) had an 80% lower risk of breast cancer than those with levels less than 20 ng/ml (50 nmol/L) (P=0.03), adjusted for age, BMI, smoking status, calcium supplement intake, and study of origin.

Type 2 Diabetes

This analysis compared type 2 diabetes incidence rates among U.S. participants aged 20 years and older in the GrassrootsHealth study (average vitamin D level = 41 ng/ml) and in the 2005-2006 National Health and Nutrition Examination Survey (NHANES) study (average vitamin D level = 22 ng/ml). We found that there was a 60% lower risk of type 2 diabetes in the GrassrootsHealth cohort compared to the NHANES cohort (P=0.01), adjusting for age, gender, race, smoking status, and BMI.

Kidney Stones

This analysis investigated the relationship between vitamin D status and kidney stones among GrassrootsHealth participants. We found that there was no association between vitamin D levels in the range of 20 to 100 ng/ml and kidney stone risk.
