Biotin is a water-soluble, B-complex vitamin. It’s found in all living cells and is essential for cellular metabolism. Biotin is also known as vitamin H, coenzyme R, and vitamin B7. Confusingly, it is also sometimes called vitamin B8, but this is unofficial and relatively uncommon (B8 more often refers to inositol). Biotin is used by all living creatures—plants, animals, and even single-celled organisms.
In animals, biotin is essential for metabolizing proteins and converting sugar into usable energy. It’s necessary for hormone production and helps maintain healthy blood sugar levels. Biotin promotes healthy hair, skin, and nails. Mammals, including humans, cannot synthesize biotin and must obtain it from dietary sources.
Biotin deficiency is rare but dangerous. The vitamin is crucial for normal fetal development and a deficiency during pregnancy can result in birth defects. Symptoms of biotin deficiency include brittle nails, hair loss, muscle pain, nausea, fatigue, anemia, and dry skin.
