Sea-Cal is a highly absorbable calcium supplement sourced from Lithothamnion spp., a species of red marine algae harvested off the clean, cold waters of Iceland. Unlike many calcium supplements that rely on bone meal, oyster shell, or limestone—sources that can carry environmental toxins or lack proper mineral balance—Sea-Cal delivers naturally occurring calcium in a porous, plant-based matrix that enhances absorption and utilization by the body.

In addition to calcium, Sea-Cal contains naturally occurring magnesium, boron, and trace minerals that work synergistically to support strong bones, joint function, and healthy nerve transmission. This full-spectrum mineral profile is especially important for pets on homemade or raw diets that may be calcium-deficient, as well as growing puppies and kittens, seniors, or pets recovering from injury or illness.

Easy to mix with food, Sea-Cal is gentle on the stomach and safe for daily use. It helps maintain proper calcium-phosphorus ratios in meat-based diets and supports balanced bone development and long-term musculoskeletal health in both cats and dogs.
