Gemcal DS Capsule belongs to the class of dietary supplements primarily used to treat low blood calcium levels. It effectively treats various conditions caused by low calcium levels in the body, such as osteoporosis (weak and brittle bones), osteomalacia/rickets (weak bones), hypoparathyroidism (low levels of parathyroid hormone), and latent tetany (a muscle disease with low blood calcium levels). Gemcal DS Capsule can also be given to pregnant, nursing, and postmenopausal women to ensure that they are getting enough calcium.
