Abstract
Nutritional or therapeutic compositions are provided for increasing ketone body levels in the blood of mammals by providing a source of ketone bodies in the form of linear or cyclic oligomers and/or derivatives of 3-hydroxyacids. The 3-hydroxyacid can be in the form of a linear oligomer of 3-hydroxyacids other than linear homo-oligomers of 3-hydroxybutyric acid if administered in combination with acetoacetate, cyclic oligomers of 3-hydroxyacids, esters of the linear or cyclic oligomers, esters of 3-hydroxyacids other than 3-hydroxybutyric acid, and combinations thereof. An oligomer generally refers to a polymer of three or more hydroxyacids. Preferred 3-hydroxyacids include 3-hydroxybutyrate, 3-hydroxyvalerate, 3-hydroxyhexanoate, and 3-hydroxyheptanoate. Oligomers of odd-carbon number 3-hydroxyacids such as 3-hydroxyvalerate have advantages since they have a higher energy content than oligomers of 3-hydroxyacids having an even-number of carbons. The cyclic oligomers have advantageous properties since they result in a sustained, and/or controlled, ketone blood level over a period of hours. The compositions can be administered orally, for example, as a nutritional or dietary supplem…
