Hydroxycitric acid (HCA), a derivative of citric acid, is found primarily in a small, sweet, purple fruit called the Malabar tamarind or, as it is most commonly called, Garcinia cambogia.hat Is the Scientific Evidence for Hydroxycitric Acid? It remains unclear whether HCA offers any weight-loss benefits. In an 8-week double-blind, placebo-controlled trial of 60 overweight individuals, use of HCA at a dose of 440 mg 3 times daily produced significant weight loss as compared to placebo.
Humic Acid. Humic acid is a liquid organic acid derived from decayed organic matter (humates or leonardites). It is the most important components of Potassium Humates. The humic acids group is defined not by chemical structure, but rather by the process through which it is isolated.he humic acid used in the manufacture of Potassium Humate is derived from a type of leonardite lignite blend that differs from its theoretical formula: part of its chemical structure has been oxidized away. These broken bonds create places on the molecules where micronutrient ions can be absorbed.
