I have 3 bottles of Dr. Weil's Juvenon. I am taking the first bottle and 1/2 + through it.They do not expire until 06/2015. I have been getting other supplements thru "Vitamin Shoppe".I would like to be on a more uniform program. I have osteoporsis and have broken a number of bones,but do not want to take the severe drugs/injections that traditional Doctors prescribe. I try and take up to 1800 to 2,000. mg. of calcium daily. I am 81 yrs. old, and in good shape for someone my age. I exercise at a gym 2-3 days a week for 1 hour. Perhaps you might assist me in suggesting supplements.
