title: L-Carnitine L-tartrate (LCLT) and dehydroepiandrosterone sulfate (DHEAS) affect red and white blood cells in aged Sprague-Dawley rats.
abstract: Supplementation with either L-carnitine or DHEAS was separately suggested to counteract age-related declines. However, little is known about any interactive effects of these substances, independently promoting mitochondrial energy metabolism, in older individuals. We thus studied the effects of 3 months of daily oral combined supplementation with LCLT and DHEAS on red (RBCs) and white blood cells (WBCs) in male Sprague-Dawley rats by determining RBC and WBC counts, lymphocyte proliferation and interleukin-2 (IL-2) synthesis in spleen lymphocytes after Concanavalin A (ConA) stimulation. Supplementation with LCLT in addition to DHEAS decreased RBCs and increased platelets in the blood of 25-month-old Sprague-Dawley rats, whereas supplementation with DHEAS alone shifted the balance from segmented neutrophile granulocytes to large lymphocytes in differential WBC counts. Based on these results, interactive effects of supplementation with L-carnitine and DHEAS on RBCs and platelets are suggested.
