What level of vitamin D is considered normal?

I recently had lab work done that identified a vitamin D deficiency. My level was eight and my doctor says that 30 is considered a normal level. I was then prescribed a vitamin D2 pill to help bring my levels up. I just read something that said vitamin D3 is the preferred type to use as a supplement and that 30 isn’t considered the “normal” level anymore, that the number should be closer to 40 or 50.

A few questions: Is it better to use D3 or D2? What level is considered normal? What are the effects of vitamin D deficiency?


Does ingesting semen have a laxative effect?

1) I have asked this question to many sites with no response, but came (sorry:) ) upon your site which seems to be willing to post just about any question and answer them too, so here goes:

Is there a laxative effect of ingested ejaculate, or is it ALL in my head (oh gosh, another one :) )? I have found that when I ingest my own ejaculate, almost invariably within a matter of a few minutes, I have loose bowels.

2) My boyfriend and I have been exploring oral sex for a couple months — but I've only just noticed that when I swallow I seem to experience a bout of diarrhea within a couple hours of doing so. Is it normal to have diarrhea from swallowing ejaculate?


Does eating ice correct an iron deficiency?

My sister has been told by one doctor that eating ice is effective for an iron deficiency. Another doctor says that this is balderdash and not effective.

What is the deal? Which opinion is correct? Why is there no consensus on the feedback physicians give for this subject?

I also would like pointers to more information for this topic.

Thanks.


Why do people find fatty or sugary foods comforting?

Why do people find fatty or sugary foods comforting? I mean, what is it in these types of foods that causes the body / mind to see this type of food as comforting or pleasurable? Surely from the point of view of the body, it prefers foods that are high in nutrients — so why do people who turn to food for comfort always turn to fatty or sugary foods that don't offer the body anything? just wondering??? and I hope that made sense because I'm sorry it's quite badly worded!


Why do my bowel movements stink so much?

I am living in a residence hall, and I never realized this until now, but my bowel movements are really smelly. It has gotten to a point where if I don't find a place to do it secretly, it becomes a great source of embarrassment. Could I be eating something that causes my bowel movements to be really smelly?


Do diet sodas spike insulin levels?

I have heard that the main reason why diet drinks, like a diet soda, can be bad on a diet, is that it can spike insulin levels and then your body expects sugar that it does not get. I have taken to the habit of only occasionally having diet drinks with meals, so that any increase in insulin is actually met with food in my system. My question is whether or not this is a good/workable strategy, or whether a diet soda is a diet soda no matter when you drink it and is therefore always a bad idea. Thank you for your time.
