Is Epsom Salt a Safe Substitute for Magnesium?

SadaNews - Despite the widespread use of "Epsom Salt" as a quick solution for relieving constipation and muscle pain, health experts warn against considering it a safe alternative to magnesium supplements. Its active ingredient, magnesium sulfate, may not be absorbed sufficiently, and excessive use can lead to serious side effects, including heart disorders and magnesium toxicity. A report published by "Verywell Health" reviews the benefits and uses of Epsom salt, the risks of excessive use, and the safe dosages that should be observed. Why is using Epsom salt as a magnesium supplement considered risky? There are several reasons why substituting magnesium supplements with Epsom salt is unsafe: You may not get enough magnesium: When taken orally, Epsom salt acts as a laxative that aids bowel movements; this means that part of its active ingredient (magnesium sulfate) is not absorbed in the body. Therefore, it may not provide a consistent daily dose. Risk of serious side effects: Epsom salt should not be taken for several consecutive days as it can harm the digestive system and other body systems. Regular use may cause stomach pain, chronic diarrhea, electrolyte imbalance, and disruptions in heart rhythms. Risk of overdosing on magnesium: Epsom salt contains a high amount of magnesium in each dose. Although some of it may be lost due to its laxative effect, the remaining amount may accumulate in the body, especially in individuals with impaired kidney function, posing a risk of toxicity even in healthy individuals. Uses of Epsom Salt Epsom salt can be mixed with water and consumed to treat constipation, or used topically by soaking in warm water or applying it to the skin with a cloth. Magnesium sulfate, the active ingredient in Epsom salt, is also used in some emergency medical cases, such as treating severe asthma attacks or certain heart rhythm disorders, under medical supervision. How much magnesium does Epsom salt contain? A teaspoon of Epsom salt contains about 495 milligrams of magnesium, which exceeds the safe upper limit for daily consumption among adults. Guidelines vary by product, but some types recommend adults take one to three teaspoons mixed with water, up to twice a day for treating constipation. It is important to note that the absorption of magnesium sulfate in Epsom salt is lower compared to other forms of magnesium, such as citrate, lactate, or chloride, making it difficult to determine the actual amount absorbed by the body. Risks of Excess Magnesium Adults need between 310 and 420 milligrams of magnesium daily, which can be obtained from food and supplements. The upper limit for dietary supplements is about 350 milligrams per day. High doses of magnesium are associated with several risks, including: - Digestive issues: Such as diarrhea, stomach pain, and nausea. - Toxicity at very high doses: Which can lead to vomiting, low blood pressure, difficulty breathing, kidney damage, cardiac disturbances, and even death in some cases. The role of the kidneys in regulating magnesium The kidneys remove excess magnesium from the body, so individuals with kidney failure are most at risk for accumulation and serious complications.
