Calcium is an important mineral that helps your teeth and bones stay strong and healthy. About 99 percent of the calcium in your body is stored in your skeleton; the rest of it helps your body perform other important functions‚ like allowing your muscles to perform and making sure that blood can flow throughout your body. Calcium also helps your nerves send messages from your brain to the rest of the body.

Symptoms of very low calcium levels include tingling or numbness in your fingers‚ muscle spasms‚ and abnormal heart rhythms. Although these symptoms are serious and require prompt medical attention‚ they mainly occur in people who have other severe health problems.

For a minor lack of calcium‚ Douglas Laboratories’ Calcium Citrate helps your body get enough calcium.

Each capsule contains 250 mg of calcium citrate‚ which is easily absorbed by your body on a full or empty stomach. Each bottle of Calcium Citrate by Douglas Laboratories contains a 250-day supply when taken at the recommended dosage once daily.
