Taking magnesium supplements can bring a range of side effects, such as drowsiness or fatigue during the day, muscle weakness, nausea, vomiting, skin flushing or diarrhea, Gurubhagavatula said. Some risks are even more serious.
Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
Generally speaking, you will find that magnesium supplements start to work after one week of using them. After one week of regular magnesium supplementation, individuals may experience benefits such as improved energy levels, reduced muscle cramps, better sleep quality, and reduced anxiety.
Early signs of excessive magnesium intake can include low blood pressure, facial flushing, depression, urine retention, and fatigue. Eventually, if untreated, these symptoms can worsen and include muscle weakness, difficulty breathing, irregular heartbeat, and even, in very rare cases, cardiac arrest.
Symptoms of magnesium toxicity, which usually develop after serum concentrations exceed 1.74–2.61 mmol/L, can include hypotension, nausea, vomiting, facial flushing, retention of urine, ileus, depression, and lethargy before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat, ...
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people.

Most experts recommend taking magnesium supplements one to two hours before bed to give them enough time to spur sleepiness and kick-start the body's relaxation response.
Magnesium is important for maintaining muscle and nervous system function, cardiac electrical properties, and for supporting immune system as well as regulating glucose and insulin metabolism [2,3].
Researchers hypothesize that magnesium may relax the central nervous system and cause chemical reactions. View Source in the body that increase sleepiness.
When taken in very large amounts (greater than 350 mg daily), magnesium is POSSIBLY UNSAFE. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
Taking magnesium supplements can bring a range of side effects, such as drowsiness or fatigue during the day, muscle weakness, nausea, vomiting, skin flushing or diarrhea, Gurubhagavatula said. Some risks are even more serious.

According to the Institute of Medicine, healthy adults can safely take up to 350 milligrams of supplemental magnesium daily. Anything at or below that level is unlikely to cause any adverse health effects.
Magnesium glycinate can help with this type of insomnia as well by regulating Gamma-Aminobutyric acid (GABA). GABA is a neurotransmitter that essentially puts your brain into “sleep mode” at night. It quiets communication, powering systems down and easing you into sleep.
