Which element is lacking to get rickets easily

For patients with rickets, vitamin D and calcium are the main elements lacking, because vitamin D and calcium deficiency will cause cartilage dysplasia in the bone joint, and it is easy to cause rickets in the later stage. And in infants who are in the growth period, if vitamin D is deficient, rickets will occur, thus causing bone joint deformation. Therefore, patients with vitamin D and calcium deficiency are prone to rickets, so patients with rickets can eat more foods containing vitamin D and calcium in their daily lives, and can supplement calcium and vitamin D to alleviate the symptoms of rickets.
