Lipotropics are substances which play fundamental role in the lipid metabolism of the organism. They are food supplements which help lipolysis. This is the process through which the fats are disintegrated and transformed into energy. Lipotropic agents achieve this as they improve the transportation of products from the lipid metabolism: ketones and the fatty acids inside the cells and in the intercellular space. They are contained in a variety of foods (mainly in meat and fish) and the easiest way to supply with enough quantity is through supplementation. Lipotropics are recommended for weight loss programs as they speed up the reduction of body fats.
