Magnesium and calcium work synergistically in the body’s muscle cells – magnesium causes muscle fibers to relax, while calcium causes them to contract – helping to prevent muscle cramping and supporting healthy heart rate and rhythm (the heart is a muscle too!).* 

The ratio of calcium-to-magnesium in Cal-Mag Citrate is ideal for individuals who want a higher amount of calcium but, due to magnesium's potential laxative effect, can’t tolerate an equal amount of magnesium.* Because of the highly absorbable forms of these two minerals, you get higher amounts of essential minerals and minimize capsule fatigue. 

Why is calcium important?
•  Studies on calcium and bone mass show that daily supplementation of a well-absorbed form of calcium promotes bone mass in adolescents, young adults, older men, and postmenopausal women.* 

Why is magnesium important?
•  Magnesium is crucial for the body to function properly because magnesium is involved in more than 600 of the body's enzymatic reactions.
•  Magnesium is essential for the health of the heart and blood vessels, brain, bones, muscles, and lungs. It also supports healthy blood sugar levels.*
•  It enhances the relaxation of smooth and skeletal muscles.*
•  Magnesium is a cofactor, along with multiple enzymes, in cellular energy production.* 

Why add vitamin C?
•  Vitamin C promotes optimal immune function.*
•  Vitamin C supports healthy collagen formation, which benefits wound healing and injury repair.*
