C-M-K Citrate - Support for Healthy Bones and Muscles

Progressive Laboratories' C-M-K Citrate provides calcium, magnesium and potassium, three important minerals that work together for better absorption and bioavailability.

Sufficient levels of calcium, magnesium and potassium are needed to support healthy muscle and nerve function, strong bones and teeth, and overall health and well-being.


The body requires calcium to maintain strong bones and to carry out various functions. Practically all the calcium in our bodies is stored in bones and teeth, where it supports their structure and hardness. We also need calcium for muscles to move and for nerves to transport messages between the brain and body parts. And, calcium helps blood vessels carry blood around the body and supports the release of hormones and enzymes that affect almost every function.


Almost half of the magnesium in the body is stored in our bones. Most of the rest of what is the fourth most abundant mineral in the body is found inside the cells of body tissues and organs, with just one percent located in our blood. However, the body works hard to maintain blood levels of magnesium.

Magnesium supports normal muscle and nerve function, a steady heart rhythm, a healthy immune system and strong bones. It also helps regulate blood sugar levels, supports normal blood pressure, and plays a part in energy metabolism and protein synthesis.


An essential mineral, potassium plays a critical role in the manufacture of protein, and maintenance of blood pressure, water balance, pH, and nerve function. Potassium also helps regulate heartbeat, blood pressure and salt levels.

C-M-K Citrate capsules provide 100mg of calcium, 100mg of magnesium and 25mg of potassium, all pH-balanced. Try it to see the difference it can make for your health!

Recommended Use: Adults: One capsule daily, or more, as directed by a doctor.
