Sodium-dependent multivitamin transporter is a protein that in humans is encoded by the SLC5A6 gene.^[5]^[6]^[7]

The SMVT is a transporter for pantothenic acid (vitamin B5) and biotin (vitamin B7) at the blood–brain barrier.^[8] It is also a transporter for alpha lipoic acid^[9] and iodide. Transport of these nutrients is competitive^[10] and a surplus of a given nutrient may saturate the transporter and prevent the uptake of other nutrients.
