Citrulline promotes fat loss in the abdominal area

Citrulline is an amino acid that promotes protein synthesis and fat breakdown.

A study conducted at the French Decartes University in Paris with overweight rats fed a high-fat diet found that supplementation with citrulline reduced blood sugar production in the liver and stimulated fat loss in the abdominal area. Citrulline increases the activity of brown adipose tissue, which increases calorie consumption and promotes fat burning.

Brown adipose tissue is a highly thermogenic tissue that releases energy as heat instead of storing it as fat. Citrulline increased levels of hormone-sensitive lipase by 150 percent, which also promoted the mobilization and utilization of fat.
