Frequently Asked Questions
Which magnesium form is best for sleep?
Magnesium glycinate (or bisglycinate) is generally preferred for sleep because it combines magnesium with glycine, an amino acid that promotes relaxation and tends to be gentle on the digestive tract.
How much magnesium should I take at night?
Common supplemental ranges for sleep support are 100–400 mg elemental magnesium per day. Start low and increase gradually, and discuss higher doses with your healthcare provider—especially if you take other supplements or have kidney issues.
Will magnesium make me sleepy the next day?
Most people report improved sleep without next-day grogginess when using appropriate evening doses. If you notice daytime drowsiness, reduce the dose or try taking it earlier in the evening.
Can magnesium cause digestive side effects?
Yes—some forms (like magnesium citrate or higher doses) can cause loose stools or cramps in sensitive people. Chelated forms such as glycinate/bisglycinate are typically gentler. If GI issues occur, lower your dose or switch to a chelated form.
