Many people turn to magnesium supplements to improve sleep, but this trend may not be safe for everyone. According to a medical article published on Verywell Health, taking magnesium without an actual deficiency can have side effects, most notably gastrointestinal disturbances.
Magnesium
Experts explain that the most common symptom is diarrhea, especially with poorly absorbed forms like magnesium oxide. Doses exceeding 350 mg daily, the recommended upper limit, can also lead to significant health problems in some cases.
In certain instances, excessive magnesium intake can lead to a condition known as hypermagnesemia, particularly in individuals with kidney problems. Mild cases may be asymptomatic, but moderate or severe cases can cause confusion and excessive drowsiness.
Magnesium and Potassium
The supplement may also interact with certain medications, so it's essential to consult a doctor before starting it, especially for those with chronic illnesses.
Data indicates that assessing magnesium levels is not a simple matter. Traditional blood tests don't accurately reflect the body's true magnesium stores, sometimes making deficiency diagnosis unclear. In these cases, supplementation may be permissible under medical supervision, with regular monitoring of magnesium levels to prevent excessively high levels.
When should you stop?
Symptoms such as nausea, dizziness, or confusion may indicate high magnesium levels, and it's advisable to discontinue supplementation and consult a doctor.
Ultimately, magnesium may help some people, especially those with a genuine deficiency, but its use without a clear need is not without risks. Most importantly, there's no proven causal link to improved sleep; it depends on each individual's condition and response.
