Helps send nerve impulses*

Calcium facilitates the messages that must be sent through the nervous system. Calcium is necessary for proper communication through the nerves. Calcium transmits impulses so nerve fibers can share information and function properly.*

Helps stimulate hormone secretions*

Calcium plays a critical role in hormone secretions. Our calcium levels are maintained under tight regulation. In the blood, hormones regulate this balance. If calcium levels are low or high, hormones are secreted or suppressed.

Helps your muscles contract*

Thanks to the role calcium plays in muscle contraction, with adequate calcium, through stimulation, your muscles will be able to contract, which pulls on your joints and allows your bones to move.

Helps regulate your heartbeat*

The beat goes on, thanks in part to calcium, which along with sodium, potassium and proteins plays a role in heartbeat regulation.

Helps maintain peak bone mass*

Throughout life, bones are constantly remodeling: Old cells are reabsorbed, and new bone is formed. As early as our 30s, we may start to lose bone. Consuming a healthy diet that provides adequate calcium and performing regular, weight-bearing exercise are important ways to help your body reach maximum bone mass and strength.

Helps build stronger bones early in life*

Calcium is the main building block of bones. Ninety-nine percent of the calcium we consume is stored in our bone warehouse; the more we have earlier in life, the more we can borrow when our bodies need it.*

Activates enzymes*

Calcium is needed to serve as a chemical signal for biological functions in the body such as activating enzymes vital to enabling your blood to clot properly.

Caltrate® 600+D may help support breast health*

Emerging science suggests that vitamin D3 may help support breast health. Caltrate® contains advanced levels of vitamin D3, and just two Caltrate® tablets provide more calcium and vitamin D3 per tablet than any other leading calcium supplement brand.

Plays a role in the blood-clotting process*

Calcium plays an important role in the blood-clotting process, and our bodies need calcium to support this process.

Plays a role in maintaining healthy teeth*

Calcium helps build and maintain healthy, strong teeth. Both baby and adult teeth need calcium to grow and develop. Calcium can also help protect against tooth loss associated with age.*

Helps maintain a healthy colon*

Calcium may be good for your colon, too. According to a major clinical study, two Caltrate® tablets a day helped maintain a healthy colon.*
