when to take vitamins?

[brutesinme]

I usually take all my vitamins right when i get up 3g vit c, multi, chrom. Does taking them all at the same time produce competition for absorbtion? Should i spread them out through the morning? My stomach is pretty strong, even on an empty stomach all three do not produce any ill feeling, i'm just considering optimal absorbtion.

multi at night and split up the rest during the day although it really isnt going to make too much of a difference to tell you the truth


the most practical thing to do though is morning and before bed.

personally i take them in the morning with breakfast then right before i go to bed

do you guys take 2 multi's a day? one in the a.m. and one before bed?

[THE_DOME]

yes i do

maybe i'll give it a shot... i never thought of doing that...

all accordin to the doseages in the vitamins i would think.......

btw, i dont think you should take 3 gr. vit C all at once.

Iv read that the body can only absorb between 500-1 gr. at once.

I split my vit C about 5 times throughout the day.

you can be sensible......

where did you read that the body could only absorb .5-1 g vit C at once?

You may have a point....

Transport of vitamin C is a saturable and dose dependent process that occurs by active transport. At the intestine and cells AA is oxidized to DHAA, which is more quickly transported across the cell membrane. Once inside the tissue or intestinal epithelium the vitamin is reduced back to AA. | The degree of intestinal absorption decreases as intake of AA increases. Intakes of 1 to 1.5 grams results in 50% absorption, but at intakes over 12 grams only 16% of the vitamin is absorbed. In contrast, an intake of less than 20 mg, has a 98% absorption rate (13). Absorption of vitamin C is greater when several individual doses of vitamin C, in quantities less than one gram, are taken throughout the day rather than one megadose (17). Eighty to ninety-five percent of the vitamin C found in foods is absorbed (13). Furthermore, the bioavailability of synthetic and "natural" forms of the vitamin differ very little despite the claims made by manufacturers (13,17). Vitamin C absorption can be impaired by a number of factors. A single large dose saturates the enzyme kinetics for vitamin C, leading to excess AA in the intestinal lumen, which causes numerous gastrointestinal problems. Pectin and zinc also inhibit AA absorption, but this mechanism is not well understood. A high iron concentration in the gastrointestinal tract may cause oxidative destruction and in turn impair uptake (13).
