Riboflavin deficiency (also called ariboflavinosis) results in stomatitis, symptoms of which include chapped and fissured lips, inflammation of the corners of the mouth (angular stomatitis), sore throat, painful red tongue, and hair loss. [3] The eyes can become itchy, watery, bloodshot, and sensitive to light. [3]
The mouth is the most noticeable feature; both upper and lower lips are full, and the mouth is wide. The mouth curves downwards and the upper lip curves outwards, due to a fleshy philtrum .

Megavitamin-B 6 syndrome has been reported in doses as low as 24 mg/day. [34] Symptoms may also be dependent on the form of vitamin B 6 taken in supplements. [27] [35] It has been proposed that vitamin B 6 in supplements should be in pyridoxal or pyridoxal phosphate form rather than pyridoxine as these are thought to reduce the likelihood of ...
Niacin deficiency is a consequence of a diet low in both niacin and the amino acid tryptophan, a precursor for the vitamin. Low plasma tryptophan is a non-specific indicator, meaning it can have other causes. The signs and symptoms of niacin deficiency start to revert within days of oral supplementation with large amounts of the vitamin. [23] [24]
The symptoms range from a minor nuisance to being disabling in their impact on eating, swallowing, and talking, and the severe forms can cause people to lose weight. There is no cure for aphthous stomatitis, [ 5 ] and therapies are aimed at alleviating the pain, reducing the inflammation and promoting healing of the ulcers, but there is little ...
Atrophic glossitis is a non-specific finding, [16] and has a great many causes, usually related to iron-deficiency anemia, pernicious anemia, B vitamin complex deficiencies, [16] unrecognized and untreated celiac disease (which often presents without gastrointestinal symptoms), [17] [18] [19] or other factors such as xerostomia (dry mouth).
The median time interval between the onset of symptoms and the diagnosis was 6 years, with a range of 26 days to 14 years. This suggests that the symptoms of MAGIC syndrome may manifest relatively long after the initial onset of symptoms. During the course of MAGIC syndrome, the signs and symptoms of BD may typically occur before those of RP. [4]
Pellagra is a disease caused by a lack of the vitamin niacin (vitamin B 3). [2] Symptoms include inflamed skin, diarrhea, dementia, and sores in the mouth. [1] Areas of the skin exposed to friction and radiation are typically affected first. [1]
