Calcirol Granules Sachet 1 gm is to treat low blood calcium levels. Vitamin D deficiency, osteoporosis (weak and brittle bones), hypoparathyroidism (the body's parathyroid glands produce low levels of calcium), latent tetany (a muscle disease with low blood calcium levels), and rickets or osteomalacia are among the conditions that Calcirol Sachet 1 gm successfully treats (softening or deforming of bones due to lack of calcium). A vitamin D deficiency happens when your body has low levels of the vitamin, which can be brought on by poor diet, poor intestinal absorption, or a lack of sun exposure. Cholecalciferol, a type of vitamin-D, is present in the Calcirol Sachet, 1 gm. It works by facilitating the uptake of calcium, phosphates, and vitamin A from various organs.Disclaimer:For more information contact your physician.
