Hydroxycitric Acid

Hydroxycitric Acid

Burn Fat / Lose Weight

Hydroxycitric acid (HCA) is, as the name applies a type of citric acid. Hydroxycitric acid is typically associated with the fruit from the garcinia cambogina plant but can be found in other tropical plants as well.

Hydroxycitric acid is commonly sold as a weight loss product and a life extension product. There are also other benefits being claimed about HCA that will be discussed later in this article.

You can purchase hydroxycitric acid most commonly in pill form as a dietary supplement but you can also find it in powder and liquid forms. Generally, when HCA is found in a liquid it is a secondary ingredient rather than the primary selling point.

Not all types of physical activity are suitable for everyone. Users take training advice at their own personal risk.

Hydroxycitric Acid and Scientific Study

You will often see supplement company websites or affiliate websites tout the benefits of hydroxycitric acid citing that in studies it has been shown to do this and that. The truth is that the only successful studies of hydroxycitric acid are animal and test tube studies.

When trials are put forth for any product, the first step is, generally, laboratory studies using a test tube or Petri dish study, or sometimes both. Human or animal fat, tissue, cells, etc. are used in the test tube or Petri dish and then combined with the intended product, or a variety of variations of the product to see what the results will be.

In this type of study, hydroxycitric acid reacted to animal cells prompting the company to conduct animal studies using hydroxycitric acid injection. The results showed that in these animals serotonin levels were increased. Because it is believed that increased serotonin levels will reduce appetite, it is believed that hydroxycitric acid will do the same thing; that is why it is primarily sold as a weight loss product.

Hydroxycitric Acid and Human Studies

When hydroxycitric acid was tested in humans, there were no increases in serotonin. If fact, none of the results that occurred in lab or animal studies were repeatable in human trial.

Unfortunately, this is a common occurrence of supplements and potential new drugs. This is why it is important that you determine whether a company has conducted any successful human trials before you determine whether the product will work. There are many other weight loss supplements with better proven science behind them.

In addition, any studies that would meet FDA approval will take several years and use a large population base when all is said and done. A 12 week trial with 50 people, for example, is not a strong or valid study.

There have been no long term studies on hydroxycitric acid to determine the possible implications of the effects of long term use of hydroxycitric acid.

Hydroxycitric Acid and Possible Benefits

In non-traditional medicine hydroxycitric acid has been used for hundreds of years by Native Indians to settle the stomach. Even today, lab and animal studies show that hydroxycitric acid can prevent stomach ulcers and aid in relief from existing stomach ulcers.

Some people claim that hydroxycitric acid can help prevent the body from storing fat, allowing you to eat more fatty foods without fear of it sticking with you. This is not a proven claim, but it is one of the claims used to sell products with HCA.

In addition, it is believed that hydroxycitric acid will use fat for energy before it will use other sources, such as muscle and carbs. If this were true, then during exercise you would be losing fat faster when taking HCA.

Hydroxycitric acid is also sold as an appetite suppressant. As mentioned above, hydroxycitric acid raises serotonin levels in animals. As such, it is marketed as a product that can do this in humans as well.

Hydroxycitric Acid and Diabetes

Studies conducted by Dutch researchers on rats in 2005 showed that HCA delayed the glucose levels in rats after a meal was eaten. The implications of this are many, especially for diabetics.

Simply put, when a diabetic eats a meal, the body is unable to properly release the glucose in the body, often releasing it all at once or not releasing it at all. It is believed that HCA controls the release of glucose over a two hour period, enabling the proper amount of sugar to be disbursed in the body preventing hypoglycemia or a need for insulin.

Again, these results were from animal studies, not in human trials, although it is very likely that human trials are being conducted in other countries for the benefits of hydroxycitric acid for diabetes

Hydroxycitric Acid and Interactions, Warnings, and Side Effects

Because there are no published human studies for hydroxycitric acid, there are no known side effects, interactions or warnings applied to this product.
