Symptoms of deficiency
Inherited metabolic disorders characterized by deficient activities of biotin-dependent carboxylases are termed multiple carboxylase deficiency. Partial biotinidase deficiency is defined as 10% to 30% of normal serum activity. Neonatal screening for biotinidase deficiency started in the United States in 1984, which as of 2017 was reported as required in more than 30 countries. Biotinidase deficiency is a deficiency of the enzyme that recycles biotin, due to an inherited genetic mutation. Without biotin, the pathway diverts to 3-hydroxyisovaleric acid.

In the United States, biotin is promoted as a dietary supplement for strengthening hair and fingernails, though scientific data supporting these outcomes in humans are very weak. However, serum testing can be useful for confirmation of consumption of biotin-containing dietary supplements, and whether a period of refraining from supplement use is long enough to eliminate the potential for interfering with drug tests. When consumed as a biotin dietary supplement, absorption is nonsaturable, meaning that even very high amounts are absorbed effectively.

Studies have shown that people with MS respond positively to daily biotin doses of up to 300 milligrams (mg). This process is important for maintaining healthy skin, and it may be impaired in people with low levels of biotin. Researchers have also studied how biotin supplements affect blood sugar levels in people with type 2 diabetes.

Overconsumption of 5 mg/day or higher causes elevated concentration in plasma that interferes with biotin-streptavidin immunoassays in an unpredictable manner. Holocarboxylase synthetase deficiency prevents the body’s cells from using biotin effectively and thus interferes with multiple carboxylase reactions.
