Calcium is a structural mineral that helps mineralize bone and teeth and participates in nerve signaling and muscle contraction.
Caution: Take with food if you experience stomach upset, and separate from high‑iron supplements by a few hours because calcium can reduce iron absorption.
Magnesium serves as a cofactor for enzymes involved in energy production and muscle and nerve function, and helps regulate calcium movement in the body.
Caution: High doses may cause loose stools, especially from magnesium oxide; start with the lowest effective dose and take with food if sensitive.
Calcium citrate supplies readily absorbable calcium for bone mineralization, while magnesium supports enzymes that manage calcium transport and muscle and nerve function. Together they cover complementary roles in skeletal and neuromuscular balance.
Label Warning: If you are pregnant, nursing, taking any medications, or have a medical condition, consult a healthcare practitioner before use. Stop use and consult a healthcare practitioner if adverse reactions occur.
Who should be cautious: People taking thyroid medications or certain antibiotics may need to separate calcium and magnesium from these by at least 2 hours due to reduced absorption. Those with kidney concerns or a history of kidney stones should discuss use with a healthcare provider before use.
Storage: Store at room temperature.

Calcium provides the building blocks that help keep bones and teeth strong and healthy. It also supports the musculoskeletal and nervous systems, and is involved with heartbeat regulation. Magnesium helps to regulate calcium transport and stimulates the secretion of calcitonin, a hormone that aids in the influx of calcium into bone. It plays an important role in protein formation and healthy muscle function. This formulation contains the highly absorbable citrate form of calcium.
Adequate calcium throughout life, as part of a well- balanced diet, may reduce the risk of osteoporosis.
As a dietary supplement for adults, take five (5) tablets daily, preferably with a meal or as directed by a healthcare practitioner.
