Help for Osteoporosis?

Yeshaya 66:14
"And you shall see, and your heart shall rejoice, and your bones shall bloom like grass ..."

Metzudas Dovid says that since worry and sadness dry up bones, the verse says at a time of simcha, the bones will be strengthened.

Do doctors recommend simcha and bitachon as ways to strengthen bones or only exercise and Vitamin D and calcium?
