Hi Kak,
I have been on Lupron since Apr. 2009. From the beginning, I have been on a supplement consisting of Vit. D, Calcium, Magnesium, Strontium, and Boron on the recommendation of my uro. The product is called Prosteon and is available from Theralogix in Rockville, Md. I should emphasize that I cannot personally recommend the product and have no definite info that it is helping me. However, I will continue to take it. My uro says it's the best supplement that he knows of.
In addition, though, it is important that your husband get regular exercise (don't overdo it) such as walking, swimming, etc. and light weight lifting. I use a treadmill and lift 5 lb. weights for a few minutes using various motions.
Check with your uro to see if supplements will suffice.
