This is the current "Recommended Daily Allowance of Magnesium" table:
Age Male Female Pregnancy
≤6 mo 30 mg 30 mg …
7-12 mo 75 mg 75 mg …
1-3 y 80 mg 80 mg …
4-8 y 130 mg 130 mg …
9-13 y 240 mg 240 mg …
14-18 y 410 mg 360 mg 400 mg
19-30 y 400 mg 310 mg 350 mg
31-50 y 420 mg 320 mg 360 mg
≥51 y 420 mg 320 mg …
But that's something approved for the mass public with normal lifestyles and this table assumes no additional factors that drain magnesium (e.g. chronic stress).
Let's assume that due to chronic stress and mental effort a person is symptomatic with magnesium deficiency symptoms like muscle weakness and fatigue and muscle twitches.
So, in such case how much magnesium can a person really eat daily? Does this make any sense whatsoever to eat for example 600 mg of Mg citrate daily or the body doesn't need more than 420 mg daily regardless of the situation?
