October is Breast Cancer Awareness Month, but here at GrassrootsHealth Nutrient Research Institute we prefer to take the opportunity each October to focus on breast cancer prevention. To help educate the public on the effects of vitamin D and breast cancer prevention, we have created a series of posts focused on key research, with highlights from the first randomized controlled trial published on vitamin D and cancer, a second study that replicated those findings, and another using data from two cohorts to show a 71% reduction in the risk of cancer. Our last post featured a study published with data combined from the Lappe cohort and the GrassrootsHealth cohort, which indicated that having a level of at least 60 ng/ml of vitamin D may have additional benefits for risk reduction of breast cancer. Today we highlight one more study looking at vitamin D and breast cancer survival.
Please share this informational series with all you know who may have or be concerned with getting breast cancer.
Vitamin D may help increase breast cancer survival rate by 60%
Tretli et al. studied 658 Norwegian patients diagnosed between 1984 and 2004 with breast cancer, colon cancer, lung cancer or lymphoma. Blood levels of 25(OH)D were determined within 90 days of diagnosis, and subjects were followed until 2008. The analysis divided patients into four vitamin D groupings of roughly equal size and plotted survival over time for each of the groups.
The following chart illustrates their findings for breast cancer survival. Notice the highest survival rate is achieved by the group with the highest vitamin D level, over 33 ng/ml (81 nmol/L).
Join the Study to Help Reduce Breast Cancer Incidence
Reduce Breast Cancer NOW! is a field trial of GrassrootsHealth using our methodology for moving nutrient research into practice. This model was developed and tested over 7 years, with over 10,000 participants, through the D*action project. All women can join this project to help demonstrate the effects of vitamin D on breast cancer prevention.

Are you concerned about your vitamin D level and cancer?
Testing your vitamin D level regularly and taking steps to keep it at a target level of 40-60 ng/ml (100-150 nmol/L) is important for all stages of health. Through GrassrootsHealth Nutrient Research Institute, you can also test your omega-3 status, inflammation levels, and levels of essential nutrients and toxins. 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 Nutrient Research Institute 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)
