Bluebonnet Calcium Citrate Plus Magnesium Caplets contain calcium in a chelate of calcium citrate plus magnesium in a fully reacted chelate of magnesium aspartate. Available in easy-to-swallow caplets for maximum assimilation and absorption. The most in-depth and clinically accurate research on bone health and its maintenance has been attributed to several important nutrients, including calcium and magnesium. Together, they are the winning ticket to bone health. In fact, there is no substitute for what these nutrients can do in the remodeling of bones, making them dense and strong for later years.* Calcium, a macromineral, is the most abundant mineral in the body. Found primarily in teeth and bones, calcium supports their maintenance and growth. Getting the proper amount of calcium every day-along with weight-bearing exercise-is essential for preventing bone loss in later life. Bluebonnet has employed calcium citrate, which is believed to be a more easily absorbed and digested form of calcium-particularly by postmenopausal women and people over 65.* Magnesium, another macromineral, not only helps maintain muscles, nerves, bones and teeth, it is essential for carbohydrate and protein metabolism, cell reproduction, and smooth muscle action, specifically the heart. Furthermore, it facilitates absorption of calcium and potassium and the processing of vitamin D. In fact, magnesium is present in every cell of the body. Over half is found in the bones, combined with calcium and phosphorus. The remainder is in soft tissue, including red blood cells and muscles.*
