normally stomach and small intestine absorb the nutrients like fat, Carbohydrate (CHO) and protein, vitamin and minerals.
the body cannot absorb the nutrients ........... normally happen on cancer and tumour patient.......they will take the supplement like vit and min tablets.........
If you feel you are not got sufficient nutrients, I advice you get it from natural food......
Because tablets only copy the 3-4 substance of the nutrient........ for example like vit C....it have 20 or 30 different kinds of shape but vit C tab only copy the 3-4 of them.....it is still not sufficient..........but in the cancer patient..better than deficiency........
so a lot of dietitians are not advice their clients to take the supplement........
if you need to take supplement.......I advice you to drink more water to avoid kidney stone....
By the way, you pay attention not overdose, because your body will tend to excret the extra vit (esp water souble).........
For example .... If you intake 1500 vitC a day(actually your body need 800 per day),
then your body will have memory that...." I will excret 700 vit C per day ".....after you stop the vit after intake for 1 year.........then your body will continuous excret 700cc vit C......
Anyways, take care .....
