111. Perspective: The Case for an Evidence-Based Reference Interval for Serum Magnesium: The Time Has Come Full Text available with Trip Pro

Perspective: The Case for an Evidence-Based Reference Interval for Serum Magnesium: The Time Has Come The 2015 Dietary Guidelines Advisory Committee indicated that magnesium was a shortfall nutrient that was underconsumed relative to the Estimated Average Requirement (EAR) for many Americans. Approximately 50% of Americans consume less than the EAR for magnesium, and some age groups consume substantially less. A growing body of literature from animal, epidemiologic, and clinical studies has (...) of a normal status as defined within the current serum magnesium reference interval of 0.75-0.95 mmol/L. This reference interval was derived from data from NHANES I (1974), which was based on the distribution of serum magnesium in a normal population rather than clinical outcomes. What is needed is an evidenced-based serum magnesium reference interval that reflects optimal health and the current food environment and population. We present herein data from an array of scientific studies to support

112. Serum Magnesium and the Risk of Death From Coronary Heart Disease and Sudden Cardiac Death Full Text available with Trip Pro

Serum Magnesium and the Risk of Death From Coronary Heart Disease and Sudden Cardiac Death Low serum magnesium has been implicated in cardiovascular mortality, but results are conflicting and the pathway is unclear. We studied the association of serum magnesium with coronary heart disease (CHD) mortality and sudden cardiac death (SCD) within the prospective population-based Rotterdam Study, with adjudicated end points and long-term follow-up.Nine-thousand eight-hundred and twenty participants (...) (mean age 65.1 years, 56.8% female) were included with a median follow-up of 8.7 years. We used multivariable Cox proportional hazard models and found that a 0.1 mmol/L increase in serum magnesium level was associated with a lower risk for CHD mortality (hazard ratio: 0.82, 95% CI 0.70-0.96). Furthermore, we divided serum magnesium in quartiles, with the second and third quartile combined as reference group (0.81-0.88 mmol/L).

119. Magnesium Bioavailability and Tolerability Do Not Differ between Two Supplements with Different Release Properties. (Abstract)

Magnesium Bioavailability and Tolerability Do Not Differ between Two Supplements with Different Release Properties. Magnesium (Mg2+) is one of the most frequently supplemented micronutrients. Due to possible gastrointestinal side effects, the European Food Safety Authority and the Institute of Medicine set the upper intake level for Mg2+ from supplements to 250 and 350 mg, respectively. Nevertheless, systematic data concerning the tolerability of Mg2+ supplements are scarce. The aim (...) of the study was to directly compare the bioavailability and tolerability of two 500 mg Mg2+ supplements in a crossover study with duplicate determination. The different release properties were either a direct release (one phase) or a delayed release of the second half (two phases). An open-label, controlled trial with a crossover design, duplicate determination, and one-week washout phases was conducted. The participants ingested the test product after overnight fasting.
