Magnesium

Magnesium is the eleventh most abundant element by mass in the human body. The adult body content is 25 g distributed in the skeleton and soft tissues. The chemical is essential in manipulating important biological polyphosphate such as ATP, DNA, and RNA and in functionming enzymes(a).

Magnesium: Bone and nutrition in elderly women: protein, energy, and calcium as main determinants of bone mineral density

In a cross-sectional study of 136 healthy Caucasian, postmenopausal women, free of medications known to affect bone, with bone mineral density (BMD) and body composition (lean and fat tissue) were measured by dual X-ray absorptiometry using specialized software for different skeletal sites, showed that independent influence of calcium, energy, and protein, examined separately and in multiple regression models on BMD of several skeletal sites. Magnesium, zinc and vitamin C were significantly related to BMD of several skeletal sites in multiple regression models (controlled for age, fat and lean tissue, physical activity and energy intake), each contributing more than 1% of variance. Serum PTH and 25(OH)D did not show significant association with bone mass(9).

Magnesium: Magnesium intake mediates the association between bone mineral density and lean soft tissue in elite swimmers

Magnesium: Magnesium intake mediates the association between bone mineral density and lean soft tissue in elite swimmers

In the study to o understand if Mg intake mediates the association between bonemineral density (BMD) and lean soft tissue (LST) in elite swimmers, showed that males presented lower values than the normative data for BMD. Mg, phosphorus (P) and vitamin D intake were significantly lower than the recommended daily allowance. A linear regression model demonstrated a significant association between LST and BMD. When Mg intake was included, we observed that this was a significant, independent predictor of BMD, with a significant increase of 24% in the R(2) of the initial predictive model. When adjusted for energy, vitamin D, calcium, and P intake, Mg remained a significant predictor of BMD. In conclusion, young athletes engaged in low impact sports, should pay special attention to Mg intake, given its potential role in bone mineral mass acquisition during growth(8).

Magnesium: Maternal first-trimester diet and childhood bone mass

Magnesium: Maternal first-trimester diet and childhood bone mass

In the study to assess the association of maternal first-trimester dietary intake during pregnancy with childhood bone mass, showed that higher first-trimester maternal protein, calcium, and phosphorus intakes and vitamin B-12 concentrations were associated with higher childhood bone mass, whereas carbohydrate intake and homocysteine concentrations were associated with lower childhood bone mass (all P-trend < 0.01). Maternal fat, magnesium intake, and folate concentrations were not associated with childhood bone mass. In the fully adjusted regression model that included all dietary factors significantly associated with childhood bonemass, maternal phosphorus intake and homocysteine concentrations most-strongly predicted childhood bone mineral content (BMC) [β = 2.8 (95% CI: 1.1, 4.5) and β = -1.8 (95% CI: -3.6, 0.1) g per SD increase, respectively], whereas maternal protein intake and vitamin B-12 concentrations most strongly predicted BMC adjusted for bone area [β = 2.1 (95% CI: 0.7, 3.5) and β = 1.8 (95% CI: 0.4, 3.2) g per SD increase, respectively(7).

Magnesium: Magnesium metabolism in 4 to 8 year old children

Magnesium: Magnesium metabolism in 4 to 8 year old children

Magnesium (Mg) is a key factor in bone health, but few studies have evaluated Mg intake or absorption and their relationship with bone mineral content (BMC) or bonemineral density (BMD) in children. In the study to measure Mg intake, absorption, and urinary excretion in a group of children 4 to 8 yrs of age, found that a small, but significantly greater Mg absorption efficiency (percentage absorption) in males than females (67 ± 12% vs 60 ± 8%, p = 0.02) but no difference in estimated net Mg retention (average of 37 mg/day in both males and females). Relating dietary Mg intake to estimated Mg retention showed that an intake of 133 mg/day, slightly above the current Estimated Average Requirement (EAR) of 110 mg/day led to a net average retention of 10 mg/day, the likely minimum growth-related need for this age group. Covariate analysis showed that Mg intake and total Mg absorption, but not calcium intake or total absorption were significantly associated with both total body BMC and BMD. These results suggest that usual Mg intakes in small children in the United States meet dietary requirements in most but not all children. Within the usual range of children's diets in the United States, dietary Mg intake and absorption may be important, relatively unrecognized factors in bone health(6).

Magnesium: Magnesium and osteoporosis: current state of knowledge and future research directions

Magnesium: Magnesium and osteoporosis: current state of knowledge and future research directions

According to the study by the University of Milan,, a tight control of magnesiumhomeostasis seems to be crucial for bone health. On the basis of experimental and epidemiological studies, both low and high magnesium have harmful effects on the bones. Magnesium deficiency contributes to osteoporosis directly by acting on crystal formation and on bone cells and indirectly by impacting on the secretion and the activity of parathyroid hormone and by promoting low grade inflammation. Less is known about the mechanisms responsible for the mineralization defects observed when magnesium is elevated. Overall, controlling and maintaining magnesium homeostasis represents a helpful intervention to maintain boneintegrity(5).

Magnesium: Nutrition and bone health. Magnesium-rich foods and bone health

Magnesium: Nutrition and bone health. Magnesium-rich foods and bone health

According to the study by the Kagawa Nutrition University, about 60% of magnesium in human body is present in the skeleton. Various foods are containing magnesium. The major sources are foods of plant origin like grain, vegetable and pulse. EAR (estimated average requirement) and RDA (recommended dietary allowance) are set for age 1 year or over in Japan. There may be a large number of people who have inadequate intake of magnesium judging by the results of the national nutrition survey. Adequate intakes of magnesium and also other nutrients related bone health are desired(4).

Magnesium: Magnesium deficiency and osteoporosis: animal and human observations

Magnesium: Magnesium deficiency and osteoporosis: animal and human observations

Although osteoporosis is a major health concern for our growing population of the elderly, there continues to be a need for well-designed clinical and animal studies on the link between dietary magnesium (Mg) intake and osteoporosis. According to the study by the University of Southern California and The Orthopaedic Hospital, Los Angeles, relatively few animal studies have assessed the skeletal and hormonal impact of long-term low Mg intake; however, these studies have demonstrated that Mg deficiency results in bone loss. Potential mechanisms include a substance P-induced release of inflammatory cytokines as well as impaired production of parathyroid hormone and 1,25-dihydroxyvitamin D. Abnormal mineralization of bones may also contribute to skeletal fragility. Clinical studies have often varied greatly in study design, subject age, menopausal status and outcome variables that were assessed. Most studies focused on female subjects, thus pointing to the great need for studies on aging males. According to the U.S. Department of Agriculture, the mean Mg intake for males and females is 323 and 228 mg/day, respectively. These intake levels suggest that a substantial number of people may be at risk for Mg deficiency, especially if concomitant disorders and/or medications place the individual at further risk for Mg depletion(3).
