I'm worried that I have a vitamin deficiency. What are the symptoms?

The most common symptom of a vitamin deficiency is fatigue, weakness, and lack of energy. Other signs can include headaches, dizziness, digestive issues, skin problems, hair loss, dry or brittle nails, and difficulty concentrating. If you experience any of these symptoms, it's important to talk to your doctor to determine if you may be suffering from a vitamin deficiency.
