What is Magnesium (Lactate)?

Magnesium (Lactate) is a magnesium salt that provides elemental magnesium in a form commonly used in dietary supplements. It helps support normal muscle, nerve, and cardiovascular function.

What are the main benefits of magnesium lactate?

It can help correct or prevent magnesium deficiency and support muscle function, normal heart rhythm, and bone health. Benefits are most noticeable when intake is low or deficiency is present.

How much magnesium lactate should I take?

Supplement doses are typically based on elemental magnesium, often around 200–400 mg per day. The exact amount depends on diet, individual needs, and product labeling.

What are common side effects or precautions?

Magnesium supplements can cause gastrointestinal upset such as loose stools, especially at higher doses. People with kidney disease or those taking certain medications should consult a clinician before use.
