Have a look at your multi and don't take too much vitamin A:

Middle-aged men with high levels of vitamin A in their blood are more likely to break a bone in later years than those with lower levels of the vitamin, report Swedish researchers this week.

The authors point to current food fortification and widespread supplement use as a possible cause of the raised levels of vitamin A.
[...]
The team concluded: “Our findings suggest that current levels of vitamin A supplementation and food fortification in many western countries may need to be reassessed.”
"One may conclude from such data that supplements containing vitamin A should not be routinely used by men or women and that fortification of cereals with vitamin A should be questioned," writes Lips.

why dont they just supplement with beta carotene. ok, its orange....but its a Vit A precursor and can be ingested in much larger amounts?

as it goes i get a lil nervoud when they fortify everything, more reason to try and watch whats in all the processed foods i guess
 
yes yes..I also read about it...my multi vit provides 15,000 IU per serving..that seems pretty much ....Read from many places that the recommended dosage is NOT more than 5000IU
