Research has shown, and continues to show, the relationships between intakes and status of certain nutrients, such as omega-3s and vitamin D, to health outcomes and disease mortality. We have previously discussed the decreased risk seen among those with a higher Omega-3 Index and death from heart disease or incidence of breast cancer, and additional significant reductions in heart attacks, cardiovascular events, and all-cause mortality published in the VITAL study among those supplementing with omega-3s.

Many studies have also been published on vitamin D and its relationship to a decreased risk for cancer and cardiovascular diseases.

Magnesium and Heart Health

Magnesium has been shown to have a strong relationship to cardiovascular health. One previously reviewed study showed how magnesium uses the same pathway as statins to lower LDL cholesterol and raise HDL cholesterol to reduce inflammation, clotting, and plaque formation in the arteries. Another study illustrated how magnesium helps regulate the heartbeat by controlling the sodium potassium pump and extending the relaxation period after contraction, which may help lower the risk of atrial fibrillation, or irregular heartbeat. Adequate intake of magnesium from the diet or supplemental sources is necessary for maintaining cardiovascular health and reducing the risk of cardiac events.

Can Magnesium Intake Affect Mortality?

Because of the strong association between magnesium and cardiovascular health, Guasch-Ferre et al. conducted a study to determine whether that association also translated to death from cardiovascular disease (CVD), cancer, and all-causes. They analyzed data from 7216 adults at high risk of CVD to further define the relationship between dietary magnesium intake, CVD (including stroke, heart attack, and cardiovascular death), and mortality from cardiovascular events, cancer, and all-causes. Dietary magnesium intake was calculated and broken down into thirds. The Low Magnesium Intake group had an average magnesium intake of 318 mg/day, the Medium Magnesium Intake group had an average of 347 mg/day, and the High Magnesium Intake group had an average of 454 mg/day.

What Did the Study Find?

Participants were followed an average of 4.8 years; during this time, 323 total deaths, 81 cardiovascular deaths, 130 cancer deaths, and 277 cardiovascular events were recorded for the group.

As shown in the chart above, when analyzed by magnesium intake group, compared to the participants with the lowest magnesium intake, the participants with the highest magnesium intake had a:

  • 47% decreased risk of CVD death (P=0.06)
  • 45% decreased risk of death from cancer (P=0.04)
  • 37% decreased risk of all-cause mortality (P<0.01)

These calculations included adjustments for BMI, smoking status, educational level, physical activity, alcohol intake, and certain disease prevalence.

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)
