Magnesium Lactate

Magnesium lactate is the magnesium salt of lactic acid. While the name "lactic acid" might make you think of sore muscles after a workout, this form is actually most famous for being incredibly gentle on the digestive tract. It is often the "secret weapon" for people who need to take large amounts of magnesium but find that every other form—even the gentle glycinate—gives them stomach issues.
