According to the Cleveland Clinic, feeling cold, particularly in the extremities, can be a sign of a common blood disorder called iron-deficiency anemia. Anemia and certain vitamin B12 deficiencies are the primary nutritional culprits when asking what vitamin deficiency makes hands cold, as both can impair the body's ability to produce healthy red blood cells and transport oxygen effectively.

According to the National Center for Biotechnology Information, micronutrient deficiencies can significantly affect thermoregulation, the body's ability to maintain a stable core temperature. If you're constantly asking "what are you lacking when you are cold?", the answer can involve various factors, ranging from diet and metabolism to underlying medical conditions.
