## Description

OsteoThera™ is formulated with a two-fold purpose: 1) to help teenagers and young adult women optimize peak bone mass and 2) to support optimal bone mineral density in older men and women. Highly bioavailable forms of minerals essential for bone health plus synergistic nutrients are included to maximize mineral absorption using the least number of pills. Calcium and vitamin D support bone mineral density, magnesium supports bone strength and remodeling, boron promotes calcium and magnesium balance, and vitamin K activates proteins used in bone metabolism.* OsteoThera™ is formulated to combine with average amounts of calcium and magnesium in the diet, taken along with MultiThera® multivitamin to provide optimal amounts of calcium and magnesium.

Thank you so much for this amazing product. It definitely works for me! When I forget to take a pill in the evening, my husband will ask me first thing in the morning if I missed a dose. I definitely sleep much better (and cooler) with Stay Cool. 😀
