2. Symptoms of Folate Deficiency
Dr. Axe outlines nine signs of a folate deficiency, some that you might blame on other causes. Some of the more obvious ones are pale skin, chronic fatigue (which is also a sign of anemia), poor digestion, and changes in mood, says the source.
However, there can be other not-so-obvious signs involved – you may get sick often due to poor immune function, have canker sores or a swollen tongue, or have prematurely graying hair. Folate is also very important during pregnancy; having too little can lead to developmental issues, it adds.
