How much calcium i need ? Here's an age chart as to the daily need of calcium and ages 9-18 need 1300 M/G , 19-50 ,1000, 51 or older 1200 so any time during the day you can take the needed supply in pill form that you need but i would take a dose or one pill when i get out of bed and another if 1000 M/G if needed at 6 PM and this would space it till it would get you at the right times of the day for complete benefit . but you can take it all at one time. but i dont like to because it seems to make my stomach hurt somewhat when i dose to large . now i dont know the foods that you eat but you know that and can take this even when eating a meal and adjust this to you .
