A new study confirms previous research that daily supplementation with two grams L-Carnitine in the form of Carnipure™ tartrate during pregnancy can significantly reduce the increase of plasma free fatty acid levels frequently observed during pregnancy. Increased levels of plasma free fatty acids are thought to be the main cause of insulin resistance, a major factor in developing gestational diabetes. The new research was conducted at the Medical University of Vienna (Austria) and published in the Journal for Obstetrics and Gynecology (Gynäkologisch-geburtshilfliche Rundschau; Vol. 49, No. 4, published May 2010).
As early as the 12th week of pregnancy and up to delivery, plasma total and free LCarnitine levels drop significantly. Low free L-Carnitine levels have been shown to result in a 2- to 3-fold down regulation of the expression of carnitine acyltransferases, the enzymes involved in fatty acid oxidation in the mitochondria. When the relative mRNA levels of these enzymes are low, the plasma levels of free fatty acids increase.
Supplementation with Carnipure™ tartrate resulted in a significant increase of the expression of these enzymes, thus resulting in significantly decreased levels of plasma free fatty acids. Additionally, the plasma levels of L-Carnitine were found to be higher after supplementation.
“Carnipure™ tartrate has clear benefits for pregnant women. It not only maintains normal L-Carnitine levels but also decreases plasma free fatty acids, thus potentially decreasing the risk for developing insulin resistance,” commented Prof. Dr. Alfred Lohninger, lead author of the study.
A nutrient produced in the body and found in some dietary sources, L-Carnitine plays a critical role in fat and energy metabolism. It shuttles long-chain fatty acids into the cells’ mitochondria where they are broken down for energy generation. Extensive research has shown that supplementary Carnipure™ plays a supportive role in many areas of health, including sports nutrition and exercise recovery, cardiovascular health, weight management and healthy aging. Carnipure™ is easily integrated into dietary supplements as well as functional foods and beverages.
