Intracal (Plain) 400 mg is a dietary supplement that primarily contains calcium, which is essential for maintaining healthy bones and teeth, as well as supporting various bodily functions, including muscle contraction and nerve transmission. This formulation is often used to prevent or treat calcium deficiencies, particularly in individuals who may not get enough calcium from their diet, such as postmenopausal women, the elderly, or those with certain medical conditions. Intracal helps to promote bone health and may reduce the risk of osteoporosis. It is typically taken orally, and the dosage may vary based on individual needs and healthcare provider recommendations. Common side effects can include gastrointestinal discomfort, such as constipation or bloating, especially if taken in excessive amounts. It is important to follow the recommended dosage and consult a healthcare professional if there are any concerns or if additional supplementation is needed.
