Abstract
The present invention relates to a novel process for preparing 2-hydroxy-4-methylselenobutyric acid from 3-methylselenoproprion-aldehyde. The 2-hydroxy-4-methylselenobutyric acid is obtained alone or as a mixture with its sulphur-containing analogue. The invention also relates to the compositions, in particular nutritional compositions, comprising a mixture of 2-hydroxy-4-methylselenobutyric acid and 2-hydroxy-4-methylthiobutyric acid, and a physiologically acceptable medium, and to the use of this mixture as a dietary ingredient.
