According to a study published in the journal *Indian Dermatology Online Journal*, nutritional deficiencies like Vitamin B12 and iron are among the less common reasons for nail hyperpigmentation.

According to medical professionals, iron deficiency anemia typically causes pale nail beds and spoon-shaped nails, not dark discoloration.

According to the National Institutes of Health, vitamin B12 deficiency is a known cause of cutaneous hyperpigmentation, including nail and skin changes. This essential vitamin plays a crucial role in cell metabolism and red blood cell formation, and when levels are insufficient, the body sends clear signals, often starting with your nails.

According to case reports, a vitamin B12 deficiency can cause a specific type of nail hyperpigmentation. While the most common presentation is pale or yellowish nails due to anemia, individuals—especially those with darker skin—may develop bluish-black, brown-gray, or dark streaks on their nails. These changes are often one of several indicators of an underlying deficiency.
