About Shell-CT Tablet

Shell-CT Tablet belongs to the ‘nutritional supplements’ class, primarily used to treat nutritional deficiencies. Shell-CT Tablet effectively treats various conditions caused by low calcium levels in the body, like Vitamin D deficiency, osteoporosis (weak and brittle bones), and rickets or osteomalacia (softening or deforming of bones due to lack of calcium).
