Folate Deficiency: A Hidden Driver of Fatigue, Headaches, and Cognitive Hurdles

Folate deficiency can cause fatigue and headaches by leading to anemia and reduced oxygen delivery, and it may also impair memory and cognitive function. True folate deficiency is rare in the US thanks to food fortification and a varied diet, though it can accompany other nutrient gaps. Folate is found in leafy greens, beans, and fortified foods, and alcohol consumption can worsen risk when intake is low. Addressing overall nutrition and hydration is important if fatigue, headaches, or memory concerns arise.
