Product Overview


  • Dietary Supplement
  • Hypoallergenic

Calcium bound to citric acid is a well-absorbed form of calcium. Citric acid is a naturally occurring organic acid that is able to efficiently bind three mineral molecules for every one of its own molecules. Studies have shown significantly more calcium is absorbed in the body from calcium citrate than from calcium carbonate. One study found patients with low hydrochloric acid levels absorbed an average of 10 times more calcium from citrate than from carbonate.

According to the U.S. Food and Drug Administration, adequate calcium throughout life, as part of a well-balanced diet and physical activity, may reduce the risk of osteoporosis later in life.

Take 1 capsule one to three times daily or as recommended by your health-care practitioner.
