Bone health; Muscle function; Nutritional replenishment
Adults with low dairy or mineral intake and people seeking simple daily bone and muscle support.
Take 1 tablet 1 to 3 times daily with meals; taking with food may improve mineral absorption and reduce stomach upset. If using other mineral supplements or medications, take at different times to minimize competition for absorption.
Contains: Soy. No yeast, egg, gluten, or wheat. No artificial color, flavor, or fragrance.
Calcium provides building blocks for bones and teeth and participates in muscle contraction and nerve signaling.
Caution: Take with food to enhance absorption and reduce stomach discomfort; separate from high‑dose iron or zinc as they may compete for absorption.
Magnesium acts as a cofactor in hundreds of enzymes, supports muscle relaxation, and helps regulate normal nerve and muscle function.
Caution: May loosen stools at higher intakes; take with food and separate from some medications to avoid interaction.
Vitamin D-3 enhances intestinal absorption of calcium and supports normal calcium balance for bone mineralization.
Caution: Avoid combining with high-dose vitamin D supplements unless advised, as excessive intake may raise calcium levels.
Vitamin D-3 promotes intestinal calcium uptake, while calcium supplies the mineral needed for bone structure and muscle contraction. Magnesium complements calcium by supporting muscle relaxation and participating in enzymes that manage calcium transport and balance.
Label Warning: If you are pregnant, may become pregnant, or breastfeeding, consult a healthcare professional before use.
Who should be cautious: People taking thyroid medications or certain antibiotics may need to separate calcium and magnesium by at least 2 hours to avoid reduced absorption. Those on high daily vitamin D from multiple products should be mindful of total intake. People with soy allergy should note this product contains soy. If using medications that may interact with calcium or magnesium, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place.

Calcium and magnesium work together in several key physiological processes. They are important in the regulation of blood pressure and are responsible for healthy muscle function. Calcium is needed for muscle contraction and magnesium for muscle relaxation. In addition, they are both components of skeletal tissue, and magnesium is necessary for calcium's absorption into the bones.
