Epsom salt can be taken by mouth as a magnesium supplement or as a laxative.Most brands recommend taking 2–6 teaspoons (10–30 grams) per day, dissolved in water, as a maximum for adults.Approximately 1–2 teaspoons (5–10 grams) is generally enough for children.Consult with your doctor if you need a more individualized dosage or if you want to increase the dose to more than what is listed on the package.Unless you have the consent of a doctor, never ingest more than the upper limit of intake stated on the package. Taking more than you need could lead to magnesium sulfate poisoning.If you want to begin taking Epsom salt by mouth, start slowly. Try consuming 1–2 teaspoons (5–10 grams) at a time and gradually increase the dose as needed.

If you use it as a laxative, make sure to drink plenty of water, which may reduce digestive discomfort. Furthermore, never take more than the recommended dosage without first consulting your doctor.
