Excessive vitamin D3 in postmenopausal women may increase the risk of kidney stones. Research by Rebecca Jackson published in the "New England Journal of Medicine" in 2006 studied the effects of vitamin D3 supplementation and calcium on the risk of hip fractures in postmenopausal women over 7 years and found that supplementation of 400 IU of vitamin D3 and 1000 mg of calcium carbonate did not significantly reduce hip fractures, but did increase the risk of kidney stones by 17 percent.
Well personally Mags I don't take any vitamins nor would I. I believe that if you have a healthy varied diet you don't need to take any supplements. I only take joint tablets to help my knee which is nothing to do with diet.

Kidney stones are of many types and have many causes.
The most common types in the US are calcium oxalate stones.
The stone should be analyzed so as to determine the approach to treatment.
Whatever the stone type, stone formers have a defect in kidney production of a solution stabilizer, normally secreted into the urine. This keeps the commonly supersaturated urine from forming precipitates (which then aggregate into stones).
There are two basic approaches indicated in most cases.
One is to drink large amounts of water each day to keep the urine diluted
The second is to reduce the urine content of components that form precipitates. For example, if the stone is a urate stone, medicines will be prescribed that reduce the body's production of uric acid. Or if the stone is calcium oxalate, large quantities of calcium should be ingested to block absorption of oxalic acid from the intestinal contents, thereby reducing the amount of oxalate that will have to be excreted through the kidneys. While high calcium intake sounds counter-intuitive, there is a solid scientific base for the recommendation, and persuasive clinical trial data showing that it works. Placing patients on low calcium diets will actually double the risk of having a second stone.
There are several other approaches that might be taken, but the foregoing hit the main points. It's important to remember that the basic defect (absence of a solution stabilizer) persists, so whatever strategy works will have to become permanent.
Vitamin D, in doses producing desirable serum levels of 25(OH)D (40-60 ng/ml or 100-150 nmol/L), does not adversely affect any of the components of this system
Sarah darlin' - you'll have to go the same route I did - have had both hips and both knees surgicaly replaced with titanium implants. I can even recommend a lovely Surgeon to do the job for you!!!
Sarah darlin' - I didn't have a lot of choice in the matter. It was either undergo the surgery and be uncomfortable for a few weeks or be in excruciating pain for the rest of my life and be permanently house-bound into the bargain. I can now get about (albeit with a walking stick) and whilst not totally without pain, it is controllable with some DF118 tablets from time to time.
