My Vit D is the D3...I take it and the multi in a gummie form ...cause I have such a hard time swallowing the BIG white pills...I take them with breakfast and supper and as for the sun I have a lovely front porch that is where I sit and look at my new books or work on some projects....:-)

My Daughter told me to take it, Her Husbands friend said its good for arthritis to..

Those of us who live in the deserts of Arizona don't worry too much about getting enough sun exposure. We would love some more cloudy days with rain. lower temperatures and a need for vitamin D supplementation.

There were several articles that came out about ayear ago that showed that over 80% of Americans are low in Vitamin D.
Vitamin D helps with bones, muscle, intenstinal function and yes, your feeling of well being....and it is because we have become a society of computer users, and indoor techno junkies....My Doctor said to take at least 1,000 units per day and to try for 10 to 15 minutes of sun....He put my mother on 50,000 units per week for three months, her level was so low...she was checked this week and her levels are now normal, so he reduced her dosage to 2000 per day. My doctor told me to tell all of my friends and relatives they need to take Vitamin D.

How would you know if you were over dosing on vitamin D? Any symptoms?

Yes, you can overdo it, but you wouldn't overdose by takling too much at one time. It would happen gradually that you'd build up an excess.

You'd also build up a toxic level of calcium. Symptoms: "Anorexia, nausea, and vomiting can develop, often followed by polyuria, polydipsia, weakness, nervousness, pruritus, and eventually renal failure. Proteinuria, urinary casts, azotemia, and metastatic calcifications (particularly in the kidneys) can develop."

This doesn't happen from too much sun, but from too much supplement taking for months on end.

A Normal daily dose of 1,000 is just fine every day. Per doctor.
My mother took 50,000 per week for months with no ill effects. She too, was under doctor's care because of the extemely low reading of Vitamin D in her blood. Her level is now normal...as long as she continues her daily dosage.

I take 1000 units a day--and get hours of sun with no suncreen--so I think I'm covered.
