According to a 2021 study, deficiencies in certain nutrients, such as vitamin B12 and folate, can cause hyperpigmentation, potentially leading to dark lips. While not the only cause, this confirms that yes, a vitamin deficiency can cause dark lips.

Up to 1 in 5 patients with vitamin B12 deficiency may experience mucocutaneous hyperpigmentation. This makes B12 a prime suspect when asking the important question, 'Which vitamin deficiency causes lip pigmentation?', but it is not the only one. A deeper dive reveals that other nutritional shortages can also play a role in altering your lip's natural color.

Case reports and medical studies have documented that vitamin B12 deficiency can cause skin hyperpigmentation, including on the lips, though it is considered a rare manifestation. While many factors influence lip color, a nutritional imbalance is a less common cause. We address the question, **Does B12 deficiency cause lip pigmentation?**, and examine the underlying physiological mechanisms and dietary strategies involved.

Research shows that up to 20% of patients with vitamin B12 deficiency may experience cutaneous hyperpigmentation. This pigmentation, which can appear on the lips, is a notable and reversible symptom, making it a key answer to the question: **What vitamin deficiency causes lip pigmentation?**
