Vitamin Deficiency: Recognizing Signs and Symptoms

Sometimes there are aspects of our health that we easily write off as part of normal life. Everybody experiences this, right? But sometimes it could actually be a warning sign of a more serious problem related to nutritional deficiencies or other health problems.

One of the key problems with identifying nutritional deficiencies lies in the fact that nutrients are used for so many processes throughout the body, so deficiency can appear in a wide variety of seemingly harmless symptoms.

Please note that the below list primarily focuses on nutrients with well defined recommended daily intakes and deficiencies, but there are also nutrients that we are only beginning to understand like plant-based antioxidants, polyphenols, amino acids and more that can also contribute to some of these symptoms. If you are experiencing any of these symptoms, you should always check with your doctor or trusted health care provider before attempting to self diagnose or treat.
