Ear creases aren't a sign of a magnesium deficiency per se. Diagonal earlobe creases can be an indicator for coronary artery disease, however, and low magnesium can contribute to heart disease. Discuss any medical concerns and diet or supplement changes with your health care provider.
Ear Creases and Heart Disease
Diagonal earlobe creases may be an indicator of coronary artery disease in some patients. A study conducted by Iranian researchers and published in a 2014 issue of "Heart India" found that over half of the heart disease patients who participated in the study had diagonal earlobe creases.
Magnesium Deficiency and Heart Disease
Low magnesium levels may contribute to heart disease. A 2013 review of heart disease research titled "The Magnesium Hypothesis of Cardiovascular Disease" led by Andrea Rosanoff, director of research and science information outreach for the Center for Magnesium Education and Research in Pahoa, Hawaii, found that magnesium deficiencies contributed more to heart disease than cholesterol and saturated fat. The recommended dietary allowance for magnesium is 310 to 320 milligrams per day for women and 400 to 420 milligrams daily for men. Food sources of magnesium include whole grains such as wheat bran, oat bran and brown rice; greens such as spinach and swiss chard; nuts such as almonds, hazelnuts and peanuts; lima beans, milk and bananas.
