I see all kinds of multi-vitamins, some very expensive, others less so. My doctor told me that if I want to take one not to spend too much as most of it just goes thru your system and you urinate it out of your system (very yellow urine). In fact he said that Centrum is fine compared to some that you see at the vitamin specialty stores. It seems some doctors say go ahead if it makes you feel better, others say it's a waste of money as 98% is excreted.
Also can you take multi-vitamins on an empty stomach? I thought someone said you're wasting them if you don't take them with food and a full glass of water.
