Short answer: Drinking Epsom salt is generally not recommended. It can cause unpleasant and potentially serious side effects, and there are safer, better- supported ways to address constipation or magnesium deficiency if needed. Details

• What Epsom salt is: Epsom salt is magnesium sulfate. When taken by mouth in recommended doses, it can act as a laxative or to raise magnesium levels in certain medical conditions, but dosing must be precise and supervised (especially in children or people with kidney problems) [health sources]. It should never be used as a routine daily remedy without medical guidance [medical sources].
• Common risks of oral use: Nausea, stomach cramping, bloating, and diarrhea are common with oral Epsom salt. More serious risks include electrolyte disturbances (like high magnesium levels), dehydration, dizziness, fainting, and potentially dangerous heart rhythm changes, particularly if misused or taken in excess [health sources].
• When it might be used medically: In certain healthcare settings, magnesium sulfate is used under medical supervision for specific conditions (e.g., certain obstetric or seizure-related indications). This is far from a general home-use practice and involves careful dosing and monitoring [health sources].
• Safer alternatives for constipation: For occasional constipation, consider higher-fiber diets, hydration, OTC laxatives with guidelines appropriate for your situation, or consulting a healthcare professional before using any laxative beyond labeled directions [medical sources].
• Special cautions: People with kidney disease, older adults, and those on certain medications are at higher risk for complications from magnesium-containing products. Always check with a clinician before taking Epsom salts by mouth [medical sources].

Practical guidance

• Do not drink Epsom salt unless a healthcare provider explicitly recommends it and provides exact dosing instructions tailored to the individual’s health status [health sources].
• If constipation is the goal, start with safer first steps (fiber, fluids, physical activity) and consult a doctor before using any laxative regularly or in large amounts [medical sources].
• If any signs of adverse effects occur after ingestion (nausea, vomiting, severe stomach pain, weakness, confusion, slowed heart rate, or irregular heartbeat), seek urgent medical care [health sources].
