One of the main and most active components of Garcinia cambogia, a native fruit of Southeast Asia, is hydroxycitric acid or HCA.
Hydroxycitric acid is believed to not only suppress appetite, but to prevent the body from creating fat, but is it true? How does the original Garcinia cambogia work?
It is believed to influence enzymes found in the body that convert unused energy, known as glucose, into fat.
Glucose is the body’s main energy source, and when glucose, broken down from carbohydrates from the foods we eat, is not consumed through exercise or energy, it is typically stored as fat.
Hydroxycitric acid contained in the rind of the fruit is believed to block the ability of those enzymes to convert unused glucose into fat.
More precisely, the main enzyme responsible in the process of converting carbohydrates into fat is known as citrate lyase. Hydroxycitric acid is believed to inhibit the ability of citrate lyase to do this.
The extract is believed to help the body break down stored fat cells as well as increase metabolism, or the rate at which the body burns or uses fat for energy.
In addition, it is believed to increase production and levels of serotonin in the brain, improving mood and act like an appetite suppressant, which can lead to a reduced risk of “comfort eating” and in turn, prevent consumption of excess calories, leading to weight loss.
It’s easily available for sale at GNC and Walmart.
A number of clinical studies have been conducted in relation to the effect and effectiveness of hydroxycitric acid from Garcinia cambogia in regard to weight loss.
In an article published in Critical Reviews in Food Science and Nutrition (“Evaluation of the safety and efficacy of hydroxycitric acid extracts in humans.“) the abstract of the article mentions several studies that showed that it did play a role in lipid biosynthesis regulation.
However, caution is also recommended when interpreting results in regard to fat loss and body weight index when it came to experimental processes on animals and humans, because results have been erratic.
Many of the studies that have been completed to date have been short term and performed on small groups, and no results have yet determined that the effects of Garcinia cambogia in this regard is effective beyond three months.
Consumers can access a number of abstracts and journal articles regarding the extract and hydroxycitric acid as a weight-loss supplements at PubMed.gov.
This is the US national Library of Medicine National Institutes of Health.
But reviews and analysis of approximately 23 small yet eligible clinical trials have determined inconclusive results.
One article was published in the Journal of Obesity in 2011 (“The use of Garcinia extract (hydroxycitric acid) as a weight-loss supplement: a systematic review and meta-analysis of randomized clinical trials.”).
It stated that while analysis of some of these clinical trials did show favorable weight-loss when utilizing hydroxycitric acid over placebos, adverse events or side effects related to the gastrointestinal tract were twice as prevalent in that group compared with those taking the placebo in one of those studies.
For this reason, among others, further studies regarding Garcinia cambogia for weight loss continue.
Because verifiable scientific evidence regarding the efficacy and safety of long-term use (longer than 12 weeks) of Garcinia cambogia for weight loss is questionable, discuss use of hydroxycitric acid when it comes to weight-loss efforts with your doctor.
Side effects, interactions, and contraindications depend on age, current health status, contributing medical factors such as disease processes or use of prescription or over-the-counter medications.
Dosages in a number of clinical trials of Garcinia Cambogia extract averaged between 1,500 mg to 4,667 mg per day. Equivalent doses of HCA ranged 900 to 2,800 mg a day.
Common Garcinia cambogia supplements available in tablet or capsule form on shelves today come in a maximum dosage of 1,500 mg per day.
