<p><b>New page</b></p><div>Absorption occurs via a rapid [[active transport]] system, with some additional [[passive transport|passive diffusion]] occurring at high concentrations. Bile salts facilitate uptake, so absorption is improved when the vitamin is consumed with a meal. One small clinical trial in adults reported that the maximum amount of riboflavin that can be absorbed from a single dose is 27&nbsp;mg.> The majority of newly absorbed riboflavin is taken up by the liver on the first pass, indicating that [[prandial|postprandial]] appearance of riboflavin in [[blood plasma]] may underestimate absorption. Three riboflavin transporter proteins have been identified: RFVT1 is present in the small intestine and also in the placenta; RFVT2 is highly expressed in brain and salivary glands; and RFVT3 is most highly expressed in the small intestine, testes, and prostate. Infants with mutations in the genes encoding these transport proteins can be treated with riboflavin administered orally.</div>FuzzyBot
