MinorCan you take Calcium and Magnesium together?
Large calcium doses crowd out magnesium
What happens

How far apart?
Leaving at least 2 hours between them avoids most of the effect.
What to do about it
Split calcium and magnesium into different slots - magnesium is a good bedtime nutrient anyway.
