What You'll Learn

Magnesium citrate is used to treat constipation
Magnesium is a mineral that the human body needs to function properly, especially for a healthy cardiovascular system, nerves, muscles, and bones. Magnesium citrate is a common form of magnesium that is often used as a laxative for gut health. It is typically safe for adults to use as a short-term treatment for occasional constipation.
Magnesium citrate works by increasing the amount of water the intestines absorb, softening the stool and making it easier to pass. It also increases pressure, prompting the muscles in the intestines to move the stool. It is available over the counter in several forms, including liquid, capsule, and powder.
Magnesium citrate is not recommended for long-term use or for treating chronic constipation. Regular use may cause the body to become dependent on it, making it difficult to pass stools without the aid of laxatives. Excessive magnesium intake can lead to dehydration, diarrhoea, or electrolyte imbalances. Other side effects of magnesium citrate include stomach cramps, nausea, and a bubbling feeling in the stomach. In rare cases, excessive magnesium intake can result in hypermagnesemia, characterised by nausea, headache, muscle weakness, and trouble breathing.
It is important to follow the directions on the package or prescription label when taking magnesium citrate. Individuals with chronic constipation should consult a doctor to discuss long-term solutions for their symptoms. Doctors may recommend magnesium citrate as a colon cleanser before surgery or certain medical procedures.

Muscle soreness after exercise can be reduced with magnesium
Magnesium is a mineral that the human body needs to function properly, especially for healthy muscles, nerves, bones, and the cardiovascular system. Magnesium deficiency, or hypomagnesemia, may result in impaired physical performance and delayed onset muscle soreness after training. Symptoms of hypomagnesemia include nausea, fatigue, reduced appetite, numbness in the arms and legs, muscle cramps, and an abnormal heart rhythm.
While most people get enough magnesium from their diet, certain individuals may need to take a supplement. Magnesium citrate, for example, is often taken as a laxative for gut health. It treats occasional constipation by increasing the amount of water the intestines absorb, softening the stool, and increasing pressure to prompt the muscles in the intestines to move the stool.
Although rare, it is possible to have too much magnesium, or hypermagnesemia, in the body. This can be caused by kidney failure, taking too much magnesium in supplements, or taking certain medications. Symptoms of hypermagnesemia include nausea, headache, muscle weakness, confusion, drowsiness, facial flushing, redness, sweating, fast or irregular heartbeat, and trouble breathing.
Several studies have shown that magnesium supplementation can reduce muscle soreness after exercise. One study found that taking magnesium for 10 days reduced muscle soreness after lifting weights. Another study showed that MgS significantly reduced muscle soreness 24, 36, and 48 hours after an eccentric bench press session. A third study found that one week of magnesium supplementation lowered muscle soreness and increased post-exercise blood glucose.
Therefore, magnesium supplementation may be beneficial for physically active individuals with low or deficient magnesium status. It is recommended that these individuals take a dose 10-20% higher than sedentary people, in capsules, and 2 hours before physical activity. However, it is important to note that the correct type, timing, and dosage of magnesium supplementation are not yet fully understood, and more research is needed.

Magnesium can be used to treat nerve damage caused by cancer treatment
Magnesium is a mineral that is essential for the human body to function properly. It is required for healthy nerves, muscles, bones, and cardiovascular health. While most people get enough magnesium from their diet, certain individuals may need to take supplements.
Magnesium citrate, for example, is often taken as a laxative to promote gut health and treat constipation. It increases the amount of water the intestines absorb, softening the stool and making it easier to pass. However, excessive magnesium citrate can lead to side effects such as nausea, headache, muscle weakness, and trouble breathing.
Regarding cancer treatment, magnesium does not prevent nerve damage caused by certain cancer drugs, such as oxaliplatin. However, it has been found that magnesium given intravenously (by IV) can help relieve nerve pain caused by cancer. Additionally, early research suggests that taking magnesium by mouth may prevent immune system damage in children receiving the cancer drug cisplatin, which is known to deplete magnesium levels.
Magnesium's role in cancer prevention and treatment is still being studied, and it appears to have a complex relationship with cancer. Some population studies have indicated that higher dietary magnesium intake is associated with a lower risk of certain cancers and cancer-related deaths. On the other hand, magnesium deficiency has been linked to an increased risk of certain cancers.
In summary, while magnesium does not prevent nerve damage from specific cancer drugs, it can help alleviate nerve pain caused by cancer when administered intravenously. The potential of magnesium in preventing immune system damage from certain cancer treatments is also promising. However, further research is needed to fully understand magnesium's role in cancer prevention and treatment.

High magnesium levels can cause muscle weakness
Magnesium is a mineral that the human body needs to function properly, especially for healthy muscles, nerves, bones, and cardiovascular systems. Magnesium citrate is a supplement that can be taken to maintain adequate magnesium levels in the body. It is also used as a laxative to treat occasional constipation.
While magnesium is essential for muscle health, high magnesium levels can cause muscle weakness. This is one of the symptoms of hypermagnesemia, or too much magnesium in the body. Other symptoms include nausea, headache, confusion, drowsiness, facial flushing, redness, sweating, fast or irregular heartbeat, and trouble breathing. Hypermagnesemia is quite rare, and most people with higher-than-normal blood levels of magnesium have kidney failure or are taking too much magnesium in supplements or certain medications.
The daily upper intake level (UL) for magnesium is 350 mg for anyone over 8 years old, including those who are pregnant or breastfeeding. However, daily supplements of less than 350 mg are generally considered safe. For those with certain health conditions, such as kidney disease, it can be challenging to get the right amount of magnesium, and monitoring blood levels is crucial.
Physically active individuals may require more magnesium than the recommended dose to prevent muscle soreness and improve recovery and training. However, it is important to maintain magnesium levels within the recommended range during the off-season. Additionally, magnesium can interact with other medications, such as muscle relaxants, increasing the risk of side effects. Therefore, it is essential to consult a healthcare provider before taking magnesium supplements, especially if you have any underlying health conditions or are taking other medications.

Magnesium supplements can be dangerous if you have kidney disease
Magnesium is a mineral that the human body needs to function properly, especially for a healthy cardiovascular system, nerves, muscles, and bones. While most people get enough magnesium from their diet, some individuals may require supplements. However, magnesium supplements can be dangerous if you have kidney disease.
Magnesium supplementation has been shown to prevent and reverse vascular and soft tissue calcifications in uremic rats. This is particularly relevant for individuals with chronic kidney disease (CKD), as vascular calcification is a serious complication of the condition. Magnesium's role in inhibiting calcification makes it a promising therapeutic candidate.
However, it is important to note that too much magnesium could have adverse effects on bone metabolism. The majority of magnesium in the body resides intracellularly and in bones as a component of minerals. Therefore, an excess of magnesium could disrupt the delicate balance of mineral metabolism, especially in individuals with CKD.
Additionally, individuals with kidney disease may find it challenging to regulate magnesium levels in their bodies. Kidney disease can cause excess loss of magnesium in urine, and certain types of medications for kidney disease may further impact magnesium levels. As a result, monitoring blood magnesium levels is crucial for those with kidney disease who are considering magnesium supplements.
In summary, while magnesium supplementation may offer potential benefits for individuals with kidney disease, it is essential to proceed with caution. The right dosage and administration of magnesium supplements should be determined in consultation with a healthcare professional, who can monitor blood levels and advise on potential side effects or interactions with medications.
