Cal-Mag FIZZ™ contains its nutrients in a more highly bioavailable form which is gentler to the stomach, and often more suitable than solid supplements, especially for children and the elderly. Our special blend of 4 different forms of ionized calcium in our exclusive effervescent formula is the most absorbable & bioavailable form of calcium available today. This means stronger bones and a much healthier lifestyle for both young and old alike.
