Calcium (Ca) is a mineral found in food and is required for muscle contractions, nerve impulse transmission, blood clotting and regulation of cell metabolism. The amount of calcium in our bodies are regulated by hormones that control intestinal absorption, bone calcium release and kidney excretion. A lack of this mineral could contribute to the development of osteoporosis which is a progressive loss of bone mass, resulting in fragile bones and fractures. Dairy foods and fortified foods are a major dietary source of calcium in the US. Vitamin D helps the body absorb and retain calcium. Please keep in mind that calcium supplements can produce side effects, such as bloating and gas.

Who knew?
- Metabolic Bone Disease occurs usually in pet turtles and is the outcome of not enough calcium circulating through their blood, also known as Soft Shell Syndrome. This can lead to repeated tremors, severe weakness, and bone fractures. This disease can be prevented with a proper diet and adequate sunlight and an additional lighting for reptiles.
