Two magnesium forms, usually one is enough.

Both are magnesium, just bound to different carriers: glycinate is gentle and calming and favours sleep and stress, while citrate draws water into the gut and is more laxative. Stacking both mainly adds elemental magnesium and digestive effects rather than new benefit.

What to do

Pick the form for your goal: glycinate at night for sleep and stress, citrate for occasional constipation. If you ever take both, keep the combined elemental magnesium sensible to avoid loose stools.
