What is CLA Extreme?

The first thing you need to know is that the common CLA Extreme ingredients. These include conjugated linoleic acid, L-carnitine, guarana, green tea extract, and chromium. Some have significant research to back them up, but they are also found in numerous weight-loss supplements.

CLA Extreme is made by several companies and is available online and at many local retailers. The cost and exact ingredients used will vary based on the manufacturer. One of the good things about the products is that the formulas are all natural, but read on…

Lack of Originality– “These Ingredients Are Everywhere”

Our first concern is the fact that CLA Extreme uses ingredients that are found in many of their competitors’ products. A lot, like green tea extract, do have solid science behind them. Unfortunately, this formula doesn’t offer much in the way of innovation. According to our Research Editor, “This isn’t necessarily a bad product. The problem is, none of the various manufacturers provide clinical proof that their version is more effective than others on the market.”

One consumer noted, “I used it for a month and to be honest it was nothing special. I wouldn’t buy it again.”

Another commented, “CLA Extreme didn’t have anything revolutionary to offer. I want something innovative and cutting edge.”

Some dieters are reassured by familiar ingredients. According to one, “I’ve used products with green tea before and had a lot of success. I like that CLA Extreme uses it and other ingredients I recognize.”

A pleased customer said, “CLA Extreme works great for me. Sometimes tried and true is the way to go.”

Side Effects– “That’s a Lot of Stimulants!”

The use of stimulants in weight-loss supplements isn’t new. But, the CLA Extreme side effects due to their inclusion bothers some users.

One frustrated reviewer said, “I get so tired of companies adding more and more ingredients that act like caffeine. They make it impossible for me to sleep and I feel jittery all day when I take them. It isn’t worth it.”

A similarly disappointed customer pointed out, “My heart flutters off and on whenever I have too much caffeine and these supplements did the same thing to me. I had to stop taking them.”

Interestingly, some reviewers actually prefer products with stimulants. One said, “I need a little extra energy boost before I hit the gym in the afternoon so I like that it does that and helps me lose weight at the same time.”

“This helped me kick my soda habit because I didn’t get the withdrawal headaches. That helped me lose even more weight so it was a win-win,” said another of the CLA Extreme reviews.

According to our research, innovative formulas and fewer side effects make customers happy. Most CLA Extreme formulas rely on routine ingredients and stimulants, which could cause issues for some. That could turn dieters away.

The Science – “Reliable Research?”

At DietSpotlight, it is important that we have proof that the ingredients being used in a product work the way they are supposed to. For most of those found in a typical brand of CLA Extreme this seems to be true, though effective amounts aren’t always added. However, many of them rely heavily on stimulants, which while proven, may be an issue for those sensitive to them.

What Users Are Saying

"This is the best CLA product I’ve tried, and I’ve tried many. Of course with any diet supplement it’s important to maintain a healthy diet and exercise regimen. This CLA helps achieve results much quicker than dieting alone."

"Could not tell any difference."

"These made me gain weight so I stopped taking them. The label on the bottle looked faded as if the bottle was sitting in the sun. Also, there wasn`t an expiration date printed on it. Maybe they sat on the shelf too long."

The Bottom Line – Does CLA Extreme Work?

Is it time to clear the shelves of CLA Extreme? If you have had extremely good experiences with the ingredients in it, you may be considering it. However, it is important to look carefully at the label and how much of each is used. There can be a big difference between formulas which is why we have reservations about giving it the green light.

If you really want to drop those extra pounds why not try a product that has tested ingredients that are carefully selected to provide optimal results. Avoid harmful side effects and look for an innovative formula.

Among the best products we’ve researched this year, one of the best is Dietspotlight Burn. The four key ingredients have been shown in documented clinical tests to help boost fat loss and kick-start metabolism. During our research we didn’t find any negative user reviews online but we did find many consumers sharing their excellent results.

The makers of Dietspotlight Burn are so confident in how well their product works that they’re offering a Special Trial Offer, which is very reassuring.

What You Should Know

There is no official website for the product CLA Extreme. It is however sold by a number of online shops, particularly online shops which are dedicated to bodybuilding and working out. We are told that CLA Extreme is a fat burner which also contains Conjugated Linoleic Acid as a major active ingredient. We are told by those who sell CLA Extreme that Conjugated Linoleic Acid will increase energy levels.


CLA Extreme contains Conjugated Linoleic Acid, L-Carnitine, Guarana, Green Tea Extract, and Chromium Picolinate.

Product Features

CLA Extreme is certainly not the only product of this type for sale on the market which contains Green Tea Extract and Guarana. Both of these ingredients contain caffeine, so you certainly may want to cut down on the amount of coffee that you drink if you decide to use this product. Chromium Picolinate which is present in CLA Extreme is also a popular ingredient in weight loss products. Chromium Picolinate is said to stabilize glucose levels in the blood. Products which contain Chromium Picolinate are not always suitable for those who suffer from diabetes and thus anyone who is diabetic should seek their Physicians opinion before using this product. Those who sell CLA Extreme tell us that it will increase energy levels due to the inclusion of Conjugated Linoleic Acid. Certainly some clinical studies carried out on mice would seem to suggest that Conjugated Linoleic Acid can increase energy levels. However the results of tests carried out on animals are not necessarily the same when it is humans involved. CLA Extreme can be purchased at a price of $16 for ninety capsules. There does not seem to be a money back guarantee upon purchase of CLA Extreme. Those who live in Canada will not be able to order this product online. As Canadian Laws state that it is illegal to ship products containing L-Carnitine into Canada.


  • There are full and comprehensive ingredient details given for this product.
  • CLA is reasonably inexpensive to purchase.
  • CLA Extreme can be ordered directly on line.


  • There is no concrete evidence that Conjugated Linoleic Acid can increase energy levels in humans.
  • If you live in Canada you will not be able to order this product on line.
  • CLA Extreme is certainly not the only product of this type to contain these ingredients.
  • We are provided with no information to explain why the manufacturers of CLA Extreme believe that it is more effective than other similar products for sale on the market.


There are a large number of other products available for sale which contains the same ingredients as are present in CLA Extreme. We have no evidence that CLA Extreme is more effective than these other similar products and so we cannot recommend it over and above them.
