For taking 2 multis a day, what if your multi already has maxed out your daily intake? I know that the numbers they put on there are not the actual numbers required for your body. Would it be bad to take it again or is it not that much of an increase and your body will probably take care of it?

And also notes I took during Nutrition class.  Although its possible the teacher's notes were skewed from whatever source she was viewing.

Correct me if I'm wrong, but doens't sodium deter calcium absorption?

I was told (and don't accept with much truth) that too much sodium pulls calcium away from the bone, so in the end it would slow down bone growth

After doing a little research, it turns out there's actually an almost-significant amount of sodium in bones as a whole. So, using critical thinking, I'd have to say that it makes no sense that sodium would go against bone growth.
But, in the world of health, it's not always as things seem.

The final answer is that milk is a very good source of calcium and it's absorbed well by your body, it's been measured and compared to the absorption from many other sources in several studies.

People can come up with all sorts of theoretical reasons why it might not be absorbed, just like I could come up with all sorts of reason why you shouldn't be able to see something as far away as the sun ("stellar dusk could block our view!","light could get 'dimmer' in that huge distance", etc, all sounding semi-plausible) but obviously they are not sufficiently relevant factors because the simple fact is that you can see the sun just fine from earth, and you do get high amounts of calcium absorbed by drinking milk.
Some of the effects people mentioned might even happen, but if they each reduced your absorption by just say 2%, who cares...
In fact even if calcium absorption from milk was only 50% and from vegetables it was 30% with most vegetables containing very little calcium and milk containing a lot, the conclusion would still be the same, drinking milk is a good way to get and absorb a lot of calcium in your body.

There are often ulterior motives for at least a few of the crazier arguments on either side of a question, too.
For example there are vegetarians that would like to convince others that any non-vegetarian diet is also unnatural and nutritionally bad even when it's not true, because they wish it was the case.  That's why it's important to actually consider the relevance of each argument or evidence and see if it really matters.
I don't eat meat/fish or wear leather (just because I don't like to hurt things if I can avoid it), which I guess technically makes me a vegetarian, but I would never claim that it's a nutritional advantage to give up meat (well aside from a small risk of prions hehe). In fact if you are trying to gain muscles you'll have a difficult time trying to compensate for all the good things that come with meat (for example the naturally occurring creatine which you can't get from just plants, etc). If you have a strong reason not to use milk (allergy etc) you can compensate in other ways, but it's not really easier or better for other reasons, and if you are not allergic and find it delicious and it makes you feel great, you definitely don't have any health reason to deprive yourself of such a great food.
It's really about being realistic and not going overboard believing something just because you would like it to be true.

Throwing my own experience in there, it's not just about the calcium intact of milk.  All those other nutrients included in the process of taking in calcium need to be of proper amounts as well.  I used to have osteoporosis (yes, the old people disease..) even though I drank about 1/2 to 3/4 gallons of milk a day.  The reason?  Vitamin D deficiency.  I have no idea about milk itself being beneficial or not to the bones, but just getting a lot of calcium by itself is not necessarily enough.
