Centrum multi-vitamins for men, what about the gender neutral multi's...??? Maybe a whole new marketing scheme coming.
I've become a bit of a supplement fool, on a search to try and resolve my tinnitus, taking taurine now with no improvement... so my two cents/research has led me to realize/focus more on empty stomach vs. full stomach for absorption.
-high level view is water soluble nutrients absorb better on an empty stomach with lots of water, dahhh, and some nutrients need fat to bind to for improved absorption.
There are tons of scholarly articles on this topic, and for B12 it apparently should be taken on an empty stomach for best absorption. Not sure I would look at it as right or wrong, just improved uptake.
-and just food for thought: water soluble nutrients are not stored in the body, hence required every day with higher chance of having a deficiency and fat soluble nutrients are stored in the body tissue: liver, fatty tissue, unlikely for the body to experience a deficiency.
And as Stu points out there may be nutrient interactions that interfere with one another, but I've found that matrix is too overwhelming to put together as I'm no PhD candidate...
