Chelated magnesium is a form of magnesium supplement in which an amino acid or another organic molecule has been bonded to it. This procedure, known as chelation, aids in the absorption and bioavailability of magnesium in the body. Magnesium citrate supplements are beneficial. Low magnesium levels are characterized by muscle tightness and discomfort caused by physical effort. Magnesium is just as crucial for bone health as calcium. Magnesium Citrate pills also relax blood vessels, which helps maintain a healthy blood pressure, promotes heart health, and improves sleep. Antacids can make chelated magnesium absorption more difficult. Before using an antacid, consult your doctor. Avoid taking an antibiotic within 2 or 3 hours after taking chelated magnesium.
