Yes, if taken accordingly to the recommended dose. Magnesium is an element present in your regular diet. The consumption of naturally occurring magnesium does not need to be limited. Magnesium consumed in dietary supplements, conversely, should not exceed the upper limit determined according to your gender and age, unless recommended otherwise by your healthcare provider. Low magnesium intake for a long period of time can lead to magnesium deficiency. Symptoms include fatigue, weakness, loss of appetite, nausea and vomiting. Extreme magnesium deficiency can cause numbness, tingling, muscle cramps, seizures, personality changes, and an abnormal heart rhythm.
Magnesium Predicting and Testing Bioavailability of Magnesium
Magnesium supplements are sometimes marketed as "super-pills" that can fix a long list of ailments such as muscle tension, low energy, and trouble sleeping in people with adequate total body magnesium. The evidence to support the claims just isn't there. Magnesium supplements are usually well tolerated by the body, but they may be linked to adverse effects such as digestive discomfort, nausea, vomiting and diarrhea. If that is your case, you might want to take it with a meal to help prevent their occurrence.
Magnesium consumed in dietary supplements, conversely, should not exceed the upper limit determined according to gender and age, unless recommended otherwise by your healthcare provider.

Bisphosphonates - If you take bisphosphonates, you should take magnesium supplements at least 2 hours before or after them. Magnesium is found naturally in many foods and is also added to some fortified foods. Some of the richest sources are: May reduce the risk of high blood pressure, heart disease and stroke - The consumption of magnesium might slightly descrease blood pressure. As a result, magnesium rich diets decrease the risk of some types of heart disease and stroke. However, caution should be warranted when drawing conclusions concerning magnesium deficiency based on the RDA without the direct measurement of magnesium status. However, up until now, there are no readily available and easy methods to assess magnesium status. Serum magnesium analysis is still the most widely available method as it appears to be clinically the most practical, accessible, and expeditious method for identifying changes in magnesium homeostasis [ 13]. However, it is no ideal method since total serum magnesium concentration is not necessarily a good reflection of total body magnesium status [ 14], but it can be of value for determining acute changes in the intake or excretion of magnesium [ 13]. Magnesium is a “super important mineral” for your body, says Holtzer. But, she says, there are a few different signs that you might not be getting enough in your diet:One limit of the current study is that serum magnesium levels were collected up to 6 h following supplement ingestion. Magnesium is primarily absorbed in the distal parts of the small intestine and in the colon. Although magnesium absorption is known to decrease from 4–5 h post-ingestion, it cannot fully be excluded that a minor part of the ingested magnesium might not yet be absorbed within the 6 h timeframe during which serum was collected. If adverse effects persist, consult with your trusted healthcare provider to determine how to best procede. Based on the in vitro tests, some supplements containing organic magnesium formulations (such as Supplement B, F, H) show similar bioavailability and dissolution results compared to Supplement A, which contains both organic and inorganic magnesium. It should be noted that Supplements B, F and H contain lower magnesium content and that similar percentages of bioaccessible or bioavailable Mg, as reported in Figure 1 and Figure 2, thus do not necessarily correspond to similar bioaccessible or bioavailable amounts of magnesium, respectively. Furthermore, in the current study, no organic magnesium supplement was tested in vivo. It thus remains to be established whether in vivo bioavailability of organic magnesium formulations differs from supplements containing both organic and inorganic magnesium.

The aim of the current study was to investigate the value of two in vitro approaches to predict the bioavailability of magnesium supplement ingestion and validate their predictive power by actual in vivo testing. Based on the in vitro approaches, two supplements with the most divergent results concerning bioaccessibility and bioavailability were selected for in vivo testing. Importantly, poor performance in the in vitro tests was shown to translate into poor bioavailability in vivo. May reduce the risk of type 2 diabetes - Magnesium might help regulate sugar levels in the blood, reducing the risk of insulin resistance, which is a condition that leads to diabetes. Scientists are now studying whether magnesium can also help treat people who have already been diagnosed with diabetes. A) The difference in serum magnesium concentration between the peak value and the concentration before ingestion of two tablets of either the placebo or Supplement A (* p = 0.05). ( B) The incremental area under the curve (iAUC) of the serum magnesium concentration starting from 60’ before ingestion of the supplement or placebo (fasted sample) up to six hours after ingestion (* p = 0.02). The benefits of magnesium supplementation are associated with their long-term use. That means it can be taken at any time of the day, as long as taken consistently.
In these situations, magnesium supplements may be necessary, but taking too much can cause or worsen diarrhea. People with chronic kidney disease should not take supplements unless prescribed by their doctor. Study protocol: A randomized crossover design was used in this phase. The study consisted of three test days, during which subjects ingested either one or two tablets of Ultractive (A) magnesium (corresponding to 196 mg and 392 mg elementary magnesium, respectively) or one tablet of B-magnum (O) (450 mg elementary magnesium). Because the manufacturer prescribed daily intake of one tablet of Ultractive (A), this condition was incorporated in the study. However, because the amount of elementary magnesium differs largely between one tablet of each supplement and because two tablets of Ultractive (A) were tested in the first phase, this condition was also included. The number of ingested tablets thus was not the same on the different test days, and the Ultractive (A) and B-magnum (O) tablets looked slightly different, making blinding of supplement intake impossible. The course of the test days was exactly the same as described for phase A, except for the supplements that were ingested. Where does magnesium come from, exactly? Magnesium is naturally found in plant and animal foods. In your body, “more than half of your magnesium is in your bones, one-fourth is in your muscles, and the rest is in fluids and tissues, such as the blood, heart, and kidneys,” says Elizabeth Somer, M.S., R.D.N., a dietitian based in Salem, OR and a medical advisory board member for Persona Nutrition. “The magnesium in bone acts not only to maintain its structure but also as a reservoir that can be used to ensure an adequate blood supply of the mineral to the rest of the body.” Dr. Bruce Bistrian, chief of clinical nutrition at Beth Israel Deaconess Medical Center and professor of medicine at Harvard Medical School, says magnesium deficiency in otherwise healthy individuals eating a balanced diet is rare. "The kidney has an extraordinary ability to reduce magnesium loss in urine, and thus achieve magnesium balance on a wide variety of intakes," he explains. You can get your fill of magnesium by eating certain foods and taking a dietary supplement, if necessary. Adult males need 400 to 420 milligrams daily and adult females need 310 to 360 milligrams daily, according to the National Institutes of Health (NIH).

Almost one in every two Americans do not receive adequate levels of magnesium from food alone and should supplement,” Somer says. Not getting enough of this mineral can result in magnesium deficiency, also known as hypomagnesemia. The signs and symptoms of magnesium deficiency can include headaches, muscle cramps ( particularly in the legs), sleep problems, anxiety, PMS, palpitations, menstrual cramps, depression, bone pain, or osteoporosis. It should be considered, however, that potential effects of magnesium supplementation may not yet be fully uncovered due to methodological problems. Suboptimal supplement effectiveness may be one such problem as this often differs between studies. Magnesium supplements are available in a variety of forms. Conventional magnesium supplements that can be found on the market nowadays contain one of the two distinct sources of elemental magnesium, inorganic, or organic salts of magnesium [ 18]. Inorganic salts (e.g., Mg oxide) provide a high loading of elemental magnesium but exhibit a very limited bioavailability as a result of their poor solubility. The organic sources of magnesium, on the other hand, offer high levels of solubility, but provide limited levels of elemental magnesium (e.g., Mg citrate). Studies on the bioavailability of different magnesium salts consistently demonstrate that organic salts of magnesium (e.g., Mg citrate) have a higher bioavailability than inorganic salts (e.g., Mg oxide) [ 19]. This finding was also confirmed by a recent study in which both urinary excretion and serum levels of magnesium were significantly higher after single-dose administration of these two supplements in a randomized cross-over study design [ 20]. Supplements: Ultractive magnesium contains both organic and inorganic Mg 2+ salts. One tablet consists of 248.72 mg Mg oxide (containing 60% Mg, corresponding to 149 mg Mg) and 380.72 mg Mg glycerophosphate (containing 12.37% Mg, corresponding to 47 mg Mg). In total, one tablet thus contains 196 mg elementary Mg. B-magnum contains 750 mg Mg oxide (containing 60% Mg), corresponding to 450 mg Mg. The placebo supplement is composed of 400 mg glycine, 300 mg hydroxypropylmethylcellulose, 500 mg cellulose, 6 mg silicium dioxide, and 1 mg magnesium stearate. Recommended dietary allowance is the average daily level of intake sufficient to meet the nutrient requirements of nearly all healthy individuals. This value is often used to plan nutritionally adequate diets for individuals.
