Backed by over 25 years of nutritional science research, you can feel good about choosing Caltrate calcium supplements.
Calcium-containing dietary supplements, taken throughout life in conjunction with a healthy diet and regular exercise, can help people meet their recommended daily calcium requirements and may help reduce the risk of osteoporosis.^ Calcium and vitamin D supplementation, when used as directed, has a long history of established bone health benefits.* And, taking Caltrate is a good way to help obtain adequate levels of these essential nutrients for populations whose intake from diet alone is insufficient.
Caltrate is formulated to meet the calcium and vitamin D recommendations from the U.S. Institute of Medicine to support bone and overall health* while staying well-below upper levels. Always talk to your doctor, or other healthcare practitioner, if you have concerns or questions regarding your personal health, and to ask if supplements are right for you.
