If you and your doctor agree that you’d benefit from taking a magnesium supplement, seek out a product made with magnesium aspartate, citrate, lactate, or chloride, which are absorbed by the body more readily than magnesium oxide and magnesium sulfate, Somer says. One-a-day multivitamins usually don’t sneak in “anywhere near enough magnesium,” she notes, so if you’re deficient, you’d need a separate supplement. 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].

But, Holtzer says, “if you find that you are unable to get enough magnesium via food, then a supplement just might be the right call.” Other times to consider a magnesium supplement, per Holtzer: 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. 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].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. Subjects: Ten healthy men volunteered to participate in this study. The subjects’ age, weight, height, and body mass index (BMI) were 24.8 ± 8.0 years, 75.7 ± 9.7 kg and 179.1 ± 5.2 cm and 23.5 ± 2.1 kg/m 2, respectively. Subjects: For both phases of the in vivo testing, different subjects were recruited. All subjects were in good health and non-specifically trained, but some of them took part in some form of recreational exercise one to three times per week. The inclusion criterion was age from 18–50 years. Exclusion criteria were smoking and using dietary supplements (including but not restricted to vitamins and minerals) in the last three months preceding and during the study. Antibiotics - Antibiotics should be taken at least 2 hours before or 4 to 6 hours after magnesium supplements to help maximize effectiveness. Magnesium can reduce their absorption.

It could soften your poop. “Magnesium citrate in particular can have a laxative effect and may cause diarrhea in some people,” says Holtzer. May boost physical performance - Research says magnesium may be beneficial for improving exercise performance, power and muscle mass. Magnesium is found naturally in many foods and is also added to some fortified foods. Some of the richest sources are: 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). You need magnesium for many tasks. It's involved in more than 300 chemical reactions in the body. Muscles need this mineral to contract; nerves need it to send and receive messages. It keeps your heart beating steadily and your immune system strong. Most people can get enough magnesium by eating foods such as green leafy vegetables, whole grains, beans, nuts, and fish.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). 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: We updated this article in April 2023 to add more information about each featured product, based on extensive research done by our team. 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.

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. The present results further support the general pattern that inorganic magnesium compounds are not as easily absorbable as organic magnesium compounds by both in vitro and in vivo testing. As mentioned, for the in vivo tests, the current study tested two supplements with opposing bioavailability profile as predicted from both in vitro tests. The selected supplement which had one of the highest predicted bioavailability differs from other formulations as it contains both inorganic (Mg oxide) and organic (Mg glycerophosphate) magnesium salts, while the supplement with the worst predicted bioavailability consists of only inorganic magnesium (Mg Oxide). The disadvantage of organic sources of magnesium holds that, although they have a higher solubility, they provide only limited levels of elementary magnesium in contrast to inorganic salt which offers a high loading of elementary magnesium. Yet, in phase B of the current study, no additive effect of ingestion of two tablets of Supplement A (396 mg elementary magnesium) compared to one tablet (196 mg elementary magnesium) on serum magnesium levels was found. Moreover, ingestion of one tablet of Supplement A led to higher serum magnesium levels compared to one tablet of Supplement O, although the latter contains more than twice as much elementary magnesium (196 vs. 450 mg elementary magnesium, respectively). These findings suggest that the solubility of a magnesium supplement is of greater relevance for in vivo bioavailability than the loading (amount elemental magnesium). One important notice is that the tolerable upper intake levels (UL) for supplemental magnesium are set at 350 mg per day in the US and 250 mg per day in Europe. It should be noted, however, that some commercially available magnesium formulations tested in the current study contain higher amounts of elemental magnesium in one tablet (see Table 1). Thus, they theoretically exceed the UL—if absorption efficiency would be 100%—and do not comply with safety and health recommendations. As in vivo bioavailability of one tablet of Supplement A (196 mg magnesium) was not higher compared to ingestion of two tablets (392 mg magnesium), and the ingestion of two tablets exceeds the UL, ingestion of only one tablet should be recommended. For Supplement O, containing 450 mg magnesium per tablet, the UL is thus exceeded, but it is highly unlikely that this effectively led to an overdose, as no bioavailable magnesium could be measured in serum following one acute ingestion. Prescription drugs for acid reflux or treatment of peptic ulcers - These can cause low blood levels of magnesium when taken over a long period of time.May combat depression and anxiety - Depression and anxiety are linked to low levels of magnesium in the body. As magnesium plays a critical role in brain function and mood, supplements can reduce these occurrences. 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. 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. 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.
Magnesium Predicting and Testing Bioavailability of Magnesium
May support better sleep - Magnesium regulates several neurotransmitters involved in sleep. It may reduce time to fall asleep, sleep quality and duration. May have anti-inflammatory effects - Increased levels of inflammation are linked to low intake of magnesium. Inflammation is a key factor to aging and chronic disease. Magnesium supplementation reduces levels of inflammation markers, such as C-reactive protein and interleukin-6. 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. Magnesium (Mg 2+) is an essential mineral involved in numerous metabolic processes, thereby playing an important role in the physiological function of the brain, heart, and skeletal muscle [ 1, 2]. Mg 2+ is a cofactor in the activation of hundreds of enzymatic processes regulating diverse biochemical reactions, including energy metabolism, protein synthesis, muscle and nerve function, blood glucose, and blood pressure control [ 3]. Magnesium is primarily stored in bone, muscle, and soft tissue, and less than 1% is present in the extracellular fluid [ 4]. Roughly 30% of ingested magnesium through food or drinking water is absorbed by the intestine, although the extent of absorption depends on the body magnesium status (increased in case of Mg 2+ deficiency). Magnesium homeostasis is further regulated through the secretion and reabsorption in the kidneys, where about 95% of the filtered magnesium is reabsorbed. Transfer of magnesium from serum to urine begins immediately when magnesium pools are saturated. People who don’t eat a varied diet with different fruits and vegetables may benefit from taking magnesium, says Amanda Holtzer, M.S., R.D., a dietitian at Culina Health. Keep in mind, per Holtzer, that “you can certainly get magnesium from your diet.” She adds, “There are plenty of plant foods that are abundant in this mineral. What’s more, a lot of processed, commonly consumed foods, such as breakfast cereals, are fortified with magnesium.”Yes, if taken accordingly to the recommended dose. The consumption of naturally occurring magnesium does not need to be limited, as any excess can be eliminated by the kidneys through the urine. Zinc supplements - When taken in high doses, they can interfere with the body’s ability to absorb and regulate magnesium. In addition, some medical conditions (such as gastrointestinal diseases, type 2 diabetes and people with long term alcoholism) and/or the use of certain medications can interfere with the body’s ability to absorb magnesium or increase the amount of magnesium that the body excretes, leading to magnesium deficiency.
