You’re about to learn everything you need to know about CLA Core. We delved deep into the ingredients, side effects, clinical studies and customer service. Furthermore, we concentrated on hundreds of consumer comments and reviews. We then scrutinized and summarized to give you the info you need. We’ve heard from so many dieters who’re tired of trying one thing about another only to end up right back at the start. After walking through everything we found, we’re not positive this one will work any better.

CLA Core Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is CLA Core?

First off, MusclePharm CLA Core is a weight-loss supplement consisting of Conjugated Linoleic Acid, Extra Virgin Olive Oil and Avocado Oil. The recommended serving size is one to two capsules per day, which supposedly helps dieters lose more weight. One important benefit for the busiest of people is portability.

The supplement, introduced by MusclePharm in 2008, does not use synthetic ingredients, a bonus. You can buy the product on the official website and through trusted retailers. We like that there are some favorable customer comments and a money-back guarantee, but if you’re looking for that definite connection with weight-loss, keep reading…

Poor Customer Service – “Hello? Anyone There?”

The first negative aspect of CLA Core service was an unwillingness to resolve concerns. “When dieters purchase supplements from a company, there’s a chance there will be questions,” said our Research Editor. “Customers expect exceptional care or they’ll spend their money elsewhere.”

  • “I ordered some products and did not receive them. I’ve contacted the company and they are refusing to assist me,” commented one user.
  • “Muscle Pharm failed on their claim to respond to their contact us form within the 24 hour claim. I have YET to receive a response from your company,” said a customer.

We looked around for positive experiences with the MusclePharm customer service department, but we were unable to find any.

FDA Judgments –  “Is This a Concern?”

On November of 2014, MusclePharm was involved in a lawsuit about a supplement other than CLA Core. The premise of the complaint related to the amount of protein in a formula. This may not directly pertain to this product, but it’s a concern because it measures the company’s honesty. The issue has yet to be resolved.

Side Effects – “Any Reported Reactions?”

According to multiple consumer comments, CLA Core side effects can be troublesome.

  • “Started taking this with my vitamins and eating a well-balanced diet and after a week of use I notice that it got harder and harder for me to go to the bathroom,” reported a dieter.
  • “It started giving me a rash on my face so I couldn’t continue using it, unfortunately I was excited to use it as well, but I have to pass on it,” said a user.
  • “This made me break out in pimples like crazy!,” said a consumer.

Though there are some negative experiences, we can’t help but share the positive ones, too.

  • One person said, “No side effects other than constant burping the first week or so.”
  • “Easy to use with little to no side effects” according to another.

Our research shows that if any part of a supplement is a concern, such as side effects, dieters may not experience long-term success. If CLA Core does in fact cause reactions, the dieter, without a doubt, will go with a formula that’s clinically tested and safe.

Is There Any Legit Science?

Although the official CLA Core website states the supplement aids in weight-loss, we couldn’t find any published science supporting the claims. That’s a shame because all the dieter wants is a product that will help them reach weight-loss goals. Having another option that may not live up to claims is a disappointment. At DietSpotlight, locating research is critical. If a company can’t provide clinical studies, we move on.

Does CLA Core Really Work?

So, we gave this one the once over and after careful consideration of CLA Core, we’ve come to a conclusion. The positives include the money-back guarantee and the availability of the product, but we are hesitant about it because the formula is not linked to published clinical research showing a strong connection with weight-loss. Plus, we have concerns about the poor BBB rating, customer service complaints and reported side effects.

If you’d like to slim your waistline and you’re tired of trying one product after another, we suggest looking for a formula with clinically tested ingredients and customer support that’s strong and positive.

We’ve been through hundreds of products this year and the best we’ve found is called Dietspotlight Burn. The four-ingredient proprietary blend has been shown in clinical testing to help boost metabolism and fat loss, exactly what the dieter has been looking for. Reports of side effects are nearly non-existent, but customer support is through the roof as more and more people report weight-loss.

The company behind Dietspotlight Burn shows confidence in the supplement by providing a special trial offer, which means that extra weight is ALL you have to lose.

Dietspotlight Burn orders are available with fast, reliable worldwide shipping. So, customers in India, Saudi Arabia, or others, can choose a country from the drop-down menu on the order page – it’s really that simple!

Previous CLA Core Review (Updated October 16, 2014):

What You Should Know

CLA Core is a conjugated linoleic acid fat burner. There are tons of these products on the market and while CLA used to be the biggest ingredient in weight loss, research does not back up the claims of many supplement creators. Conjugated linoleic acid is commonly found in meat and added to some protein supplements. The most common source of the acid, however, is safflower oil. MusclePharm, the creator of CLA Core, combines CLA with olive oil and avocado oil. While the supplement may support heart health, there is very little impact, if any, on weight loss.

List of Ingredients

  • Conjugated Linoleic Acid
  • Extra Virgin Olive Oil
  • Avocado Oil

Product Features

MusclePharm sells CLA Core on Bodybuilding.com where a complete list of ingredients is offered in label format. The product description is tiny and offers no evidence that any of the claims are clinically proven. The main ingredient in CLA Core is conjugated linoleic acid or CLA. CLA is clinically proven to boost lean muscle mass and reduce body fat in athletes and fit users. The same results are not proven in the overweight population. Olive oil and avocado oil provide a good source of fatty acids, ideal for promoting overall health, but not great for weight loss. If a dieter is following a low-carbohydrates diet plan like Atkins, this supplement is completely within the rules of the diet and may help the dieter lose more weight by providing a healthy fat to the diet. However, each softgel contains only one gram of fat, so the impact even with a low-carb diet is minimal. When we searched the official website for MusclePharm, we did not notice CLA Core listed as one of the products. Either MusclePharm is no longer producing the supplement or they are not promoting it actively online. If MusclePharm is not willing to stand behind the product on the official website, why should the dieter trust the supplement?


  • Ingredients are listed online.
  • CLA may improve lean muscle mass and decrease fat stores in athletic users.
  • Some clinical testing has been completed on CLA.
  • Fatty acids support cardiovascular health.


  • Will not impact metabolism for the average dieter.
  • CLA may cause some gastro or stomach side effects.


CLA Core is another conjugated linoleic acid supplement that claims to help the dieter burn more fat. This supplement is not listed on the MusclePharm website so either the company has chosen to sell it under the radar or it's not the hit they thought it would be. With so many CLA supplements available, this one does not stand out above the rest.
