                                Oral biotin supplements demonstrate nearly complete absorption, even at high pharmacological doses, with one study showing 100% bioavailability. This water-soluble B vitamin, whether from dietary sources or supplements, is efficiently absorbed by the body through multiple digestive pathways to support cellular health and metabolism.
