For Girls AND Women Of All Ages
Approximately 150,000 people in the United States are diagnosed with colorectal cancer each year and half of them are women. 
According to a recent study conducted at the University of Minnesota Cancer Center, calcium supplementation can significantly reduce the risk of colon cancer, and the combination of dietary and supplemental calcium resulted in the greatest effect. While women consuming more than 800 milligrams of dietary calcium each day reduced their risk of colon cancer by 26%, women who consumed more than 800 milligrams of calcium through a combination of diet and supplements reduced their risk of colon cancer by 46%!
"It is especially notable that the risk reduction was present regardless of the source of the calcium, and that simultaneously consuming high levels of calcium from both diet and supplements further reduced risk," said Dr. Andrew Flood of the University of Minnesota Cancer Center and School of Public Health. Flood continued, "These observations suggest that it was the calcium per se, and not merely dairy products or some other variable, that accounted for the reduction in risk."
The data from this study is substantial: More than 45,000 women were included in the study, which lasted ten years. Dr. Flood admits that more research is needed to determine specifically how calcium works to prevent this disease. (Colorectal cancer is the second-leading cause of cancer death in the United States.) One theory Flood offers is the idea that, "Calcium has a direct impact on a whole series of biochemical pathways within the cells that line the colon and rectum. These pathways play important roles in regulating how these cells grow and mature, and thus can be important components of the cancer process."
In addition to cancer prevention, calcium has longed been linked to the prevention of osteoporosis, and new research indicates that calcium supplements should begin at an earlier age than previously believed. Over a period of seven years, Dr. Velimir Matkovic, Director of the Osteoporosis Prevention and Treatment Center and the Bone and Mineral Metabolism Laboratory at Ohio State University,  conducted a clinical trial of girls aged eight through thirteen to determine the impact of calcium supplementation on bone density.  Dr.Matkovic explains, "The pubertal growth spurt accounts for about 37 percent of the gain in the entire adult skeletal mass, meaning inadequate calcium intake during the period compromises the bone mineral accumulation rate."
Researchers found that calcium supplementation significantly increased bone mass development. Of the 354 girls in the study, the calcium-supplemented group showed a faster rate of bone mass development.  These findings suggest that elevated calcium use by pre-adolescent girls is likely to help prevent fractures and osteoporosis later in life.
"Because most bone mass is accumulated during this phase of growth, preadolescence may represent the time of highest need for calcium in a female's lifetime," concludes Matkovic. 
GNLD has understood the importance of calcium supplementation for many, many years. For that reason, calcium is included in several GNLD products.
As new research continues to affirm the importance of quality nutritional supplements, GNLD once again finds itself at the forefront of nutritional science.
