Headaches
Headaches, common among adults and children with B12 deficiency, have been linked to this condition. A 2019 study involving 140 participants, half of whom suffered from migraines, found significantly lower B12 levels in those experiencing migraines. Participants with the highest B12 levels had an 80% lower chance of migraines than those with the lowest. This suggests that B12 supplementation could potentially alleviate migraine symptoms for some individuals, although further research is needed. [2]
Pale or Yellow Skin
Anemia caused by B12 deficiency can result in a pale skin appearance, similar to iron deficiency. Additionally, B12 deficiency can lead to jaundice, which gives the skin and the whites of the eyes a yellowish hue. This is due to an accumulation of bilirubin, a byproduct of red blood cell breakdown. The lack of healthy red blood cells caused by B12 deficiency not only affects skin color but also can signal more severe health issues that require attention.
