Citrimax is a hydroxycitric acid (HCA) supplement made from the Indian Garcinia Cambogia fruit. It is commonly used in weight loss products as a carb blocker. However, this carb blocking ability was based on animal studies.

The early animals studies using Citrimax showed that it was very effective at keeping carbs from being converted to fat. The results also showed it capable of suppressing appetite. Thus it began to be used in weight loss products for humans without any double-blind, placebo-controlled clinical trials.

There have since been studies on its effectiveness in humans and they results show that it does not help with weight loss in humans. Additionally, it does not seem to have any ability to suppress appetite. However, there is a small European study that saw appetite suppression and improved energy intake results.

Some still have hope for Citrimax and HCA supplements to be effective for weight loss. It is thought that the studies just have not used large enough doses to see the same results as were seen in animals. Additionally, there are now improved forms of Citrimax that are more easily absorbed, thus providing improved results.

There is at least one clinical study (J Med. 2004;35(1-6):33-48) that shows the improved formulas do prove to be much more effective than the original. The study used a much higher dose than early human studies, thus showing that a large dose can be effective at helping with weight loss at least when the users keep a 2,000 calorie daily diet and walk at least 30 minutes five times a week.

Citrimax does not seem to provide major results, but in highly concentrated doses it does seem to be effective at helping with weight loss. However, it is still important that you eat a healthy diet and exercise regularly to get any results. (Posted on 2/12/11)

I was looking for a substitute for my SOBE Lean drinks that have become impossible to locate. I noticed that they contain the product lsited above, so I decided to try it. It is a good product but does not give the same lift , energy, and appetite suppressant that the drink does. (Posted on 7/12/09)
