Cal Mag delivers a balanced 2:1 ratio of calcium and magnesium to support bone health, muscle function, and cardiovascular wellness. Each 4-capsule serving provides 600 mg of elemental calcium and 300 mg of elemental magnesium, using highly bioavailable chelated forms to promote optimal absorption and cellular energy metabolism. Additionally, this formula includes vitamin D3, vitamin K1, vitamin K2 (MK-7), boron, and silica (from horsetail extract) to further support calcium utilization and bone strength.
Calcium is the most abundant mineral in the human body, making up 1.5% to 2% of total body weight, with 99% stored in bones and teeth. It plays a critical role in:
Magnesium is an essential mineral that serves as a cofactor for over 300 biochemical reactions and is necessary for every organ to function properly. The adult body contains approximately 25 grams of magnesium, distributed among bones, muscles, blood, and tissues. Magnesium plays a key role in:
Calcium and magnesium work together to support muscle function, nerve signaling, and cardiovascular health. Calcium is essential for initiating muscle contraction, allowing muscles to tighten and perform movements. In contrast, magnesium serves as a natural counterbalance by promoting muscle relaxation, which helps prevent cramps and supports proper muscle coordination. This balance is especially important for heart health, as the heart—a muscle itself—depends on calcium for contraction and magnesium for relaxation to maintain a steady rhythm.
The body’s need for calcium is typically higher than its need for magnesium, which is why a 2:1 ratio is considered optimal. This ratio aligns with how these minerals are naturally utilized in the body, ensuring adequate calcium intake without overshadowing magnesium’s vital role in muscle relaxation and bone metabolism. Furthermore, magnesium plays a key role in calcium absorption and regulation, helping direct calcium into bones rather than soft tissues, where it could contribute to imbalances. By maintaining this 2:1 calcium-to-magnesium ratio, individuals can better support bone density, muscle performance, and overall wellness while reducing the risk of nutrient deficiencies.
For maximum calcium absorption and bone health, Cal Mag includes:
Cal Mag is manufactured in a US FDA-inspected, GMP-compliant facility using the highest quality raw materials. Testing is conducted at multiple stages of production to ensure purity, potency, and efficacy.
