When buying Caralluma fimbriata extract, look on the label for the source of the product, the active ingredient, the concentration of Caralluma and the extraction ratio. Also look for a reputable manufacturer of the product, according to Dr. Tim Boyer for eMaxHealth.
The source of Caralluma fimbriata extract should be a reputable company such as Gencor. The desired active ingredient is Slimaluma. Sold under the names Slimaluma Plus, GenaSlim and Slenderluma, Slimaluma has generally been recognized as safe since 2006 and is kosher, organic and halal. Concentrations of at least 500 milligrams in each capsule and an extraction ratio of 10 to 1 for Slimaluma should be displayed on the label, says Dr. Boyer
