“…In general, Mg was bioavailable from all test products. This finding is consistent with the results of prior studies that revealed Mg bioavailability from mineral water and dietary supplements [17–20,26]. Urinary Mg excretion increased after the consumption of all test products, and 24 h urinary Mg excretion did not significantly differ among the test products.…”

The aim of the present study was to compare the magnesium bioavailability from four mineral waters with different types of mineralization (e.g. SO4 2-, HCO3 −, calcium) with the magnesium bioavailability from bread and from a magnesium supplement. A single-center, randomized, controlled trial with a crossover design with 22 healthy men and women was conducted at the Institute of Food Science and Human Nutrition, Leibniz University Hannover, Germany. The participants consumed the six test products providing 100 mg of magnesium each on six examination days with a one-week washout phase in between. The primary outcome variables were the 24 h urinary magnesium excretion, the 24 h urinary magnesium/creatinine ratio, and the area under the curve of serum magnesium levels for 10 h (AUC0-10h). No significant differences among groups were observed for either 24 h urinary magnesium excretion or 24 h urinary magnesium/creatinine ratio. Likewise, statistical group comparisons of AUC0-10h for serum magnesium levels revealed no significant differences among the treatment groups. Accordingly, given equivalent magnesium availability from all test products, neither SO4 2- content nor the content of HCO3 − or of calcium influenced the bioavailability of magnesium. Thus, mineral water with higher concentrations of magnesium constitutes a calorie-free magnesium source that contributes to optimal magnesium supply.

“…Thus, subjects with low initial serum Mg levels, suggesting a severe tissue Mg deficiency, have remarkably elevated urinary Mg retention [20]. In this study, the fasting Mg levels of all participants were within the normal range.…”

The present study investigated the biochemical composition of three seaweeds; Ulva fasciata (Chlorophyta), Sargassum linifolium (Phaeophyta) and Corallina officinalis (Rhodophyta). Total chlorophyll content was maximum in U. fasciata (34.06mg/g dry wt.) while carotenoid content was the highest in C. officinalis (3.8 mg/g dry wt.). The uppermost level of carbohydrates was (27.98% of dry wt.) in C. officinalis and proteins were maximum (14.89%) in S. linifolium. Aspartic, glutamic, alanine, leucine and proline were common amino acids in the three tested species. The polyunsaturated ω6 and ω3 essential fatty acids were recorded in S. linifolium (3.28%) and in U. fasciata (3.18%). The results showed that U. fasciata contained the highest amounts of lipids (2.96%), phenols (11.95mgGA/g dry wt.), flavonoid (7.04 mgCA/g dry wt.) and ascorbic acid (4.11mg/100g), respectively. β-Carotene was maximum (3940.12 IU/100 g) in C. officinalis. DPPH antioxidant activities were the highest in U. fasciata (81.3%) followed by S. linifolium (79.8%) then C. officinalis (72.6%). Among the 12 analyzed minerals, most of them were high in S. linifolium in which ion quotient ratio was the smallest (0.343). Since these algal species are common in the Egyptian coastal waters, their biochemical composition and antioxidant activities made them promising candidates for nutritional, pharmaceutical and medicinal applications.Keywords: seaweeds; biochemical composition; elemental analysis; antioxidant activity.Practical Application: Seeking for new supplies for food, feed, drugs and treatments Macroalgae (seaweeds) proved to be safe, economic and eco-friendly natural sources for multi-purpose applications.

Absorption and Effect of the Magnesium Content of a Mineral Water in the Human Body

Abstract: Magnesia's high Mg (204 mg/M) and low Na (5.4 mg/L) content makes it an excellent source of Mg for patients suffering from heart problems and/or high blood pressure.
