Look Slim 90 Review - Does This Weight-Loss Supplement Work? Are poor customer service and lack of results deal breakers?

Editor's Review: 3.5 / 5.0
Look Slim 90 Review

There’s some buzz surrounding Look Slim 90, so we took a detailed look at the ingredients, side effects, clinical research and customer service. We scoured hundreds of user reviews and comments. We then took our findings, condensed and summarized to give you the info you need.

EDITOR'S TIP: Combine Look Slim 90 with a proven fat burner such as Leptigen for better results.

What You Need to Know

To start, Look Slim 90 is a weight-loss supplement that contains raspberry ketones. If you take two before bed each night, the company claims it will “assist the body in shedding excess body fat naturally.” The pills come in a small bottle so there’s no trouble traveling with it.

The product, which is created by an unknown company, appears to use only natural ingredients, a good decision. You can buy it from the official website, but it is not available anywhere else. We like that some users report positive effects and the price is reasonable, but read on…

Customer Service – “Supportive?”

The first thing we worry about with Look Slim 90 is the customer service department. “Representatives are the dieter’s connection to a company,” says our Research Editor. “If a business is not willing to give support, that can cause a serious trust issue.”

“Funny thing was the number you called day or night was the same old man voice on the phone. My had gotten lost in the mail and I had called several times before it got here and when I would ask him about it and give my name you could hear paper in the back ground like he was looking through his notes..lol,” offers one buyer.

“I returned the 3 month supply, they can not find the package that I sent and have not credited my account as of today. It has been a 3 month process and multiple calls and they still have not found the package and have not credited my account. I am frustrated beyond belief and feel as if they are waiting for me to just give up,” says another.

Lack of Results – “May Not Work”

You don’t spend your money on a supplement because you just want to. You’re looking for results, but users claim you won’t find any when you take Look Slim 90 ingredients. “I took your product for three months and absolutely los only three pounds. Only thing I got out of it was heartburn each morning. Think I really wasted my money here,” a dieter explains.

“It is a joke…it does not work….I gained 10 pounds on this junk!!!,” another user complains.

Our research shows a connection between a negative, like poor customer service, and a lack of long-term success. If Look Slim 90 representatives can’t be there for dieters, there’s really no reason to give this one a try.

What Does Science Say?

Look Slim 90 diet is not backed by clinical support and the company doesn’t bother trying to say it is. According to the National Institutes of Health, there is “insufficient research to draw firm conclusions” about raspberry ketones. All of the studies we found on the ingredient were completed on mice and rats, not humans. DietSpotlight looks to the science to back up a product’s claims. If that’s not there, the dieter needs to think twice about buying the supplement.

The Bottom Line – Does Look Slim 90 Work?

Our deep dive into Look Slim 90 was interesting. We like that the ingredients are shown on the official website and we did find a few positive comments, but we have doubts about a product with absolutely no clinical support. We are also a bit concerned that there is no information on the company behind the supplement and raspberry ketones are considered a “fad”.

If you’re ready to slim down, we suggest trying out a product that combines a clinically proven formula that doesn’t include “fad” ingredients. We also think a supportive customer service department is a big deal.

Among the best products we’ve seen in 2016 is one called Leptigen. The proprietary blend of four ingredients has been proven in published studies to help support metabolism and fat loss. We found no dieters mentioning a single negative side effect, but we did find quite a few users who’ve seen great results.

Also, the makers of Leptigen are confident enough in the supplement to offer a Special Trial Offer, a great sign.

What You Should Know

Click Here To See Our Highest Rated Review

Look Slim 90 is a night time weight loss supplement that claims to work while the dieter is sleeping. The dosage instructions tell the dieter to stop eating at least three hours before bedtime. This could be the reason dieters lose weight taking the supplement as the ingredient list is lacking any metabolism boosting ingredients. There are no sleep aids or stimulants in the formula. Metabolism boosters that you could use are products like Puregenix Garcinia Cambogia or Phenelite. The official website for Look Slim 90 is a bit difficult to navigate. There are a few product claims of weight loss, but no clinical references to studies that support the use of the primary ingredient for weight loss.

List of Ingredients

Collagen Protein, Gelatin, Magnesium Stearate and Cellulose.

Product Features

There is only one ingredient in Look Slim 90, collagen protein. Collagen protein naturally occurs in the muscles of mammals. There are various health benefits and medical uses for collagen protein, but none have anything to do with weight loss. Typically, collagen protein is included as an ingredient in anti-aging supplements. When consumed, collagen protein is broken down during digestion the same as any other protein. This results in an increase in amino acids, but not a direct link to weight loss. Look Slim 90 sells for $50 for a one-month supply. There is more protein in a protein shake than there is supplied by Look Slim 90. The product costs more than the typical protein powder and offers none of the weight loss benefits of protein. When protein shakes are taken as meal replacement, it digests very slowly leading to reduced hunger between meals. This is a fantastic benefit of protein, but not a benefit associated with Look Slim 90. A similar product that is also a protein shake is 18 Shake. Dieters who want to lose weight need two main ingredients in a supplement - fat burner and appetite suppressant. Fat burners cannot be taken at night because they increase heart rate. Appetite suppressants can be taken at any time of day and some dieters find they reduce the need for late night eating and overnight snacking.

  • Supplies a source of protein.


  • Collagen protein will not increase weight loss.
  • None of the ingredients will boost metabolism.


Look Slim 90 claims to use the power of collagen to boost weight loss. The fact that collagen breaks down in the digestive system to amino acids ruins these claims. Protein shakes can be utilized to reduce hunger and even work as a late night snack to reduce the need to snack late at night. Look Slim 90 is priced higher than any other protein supplement out there, because very little protein is included in each serving. Dieters would see better benefits from taking a green tea, caffeine and chromium-based supplement.

Look Slim 90 Ingredients:

We dug deep into the Look Slim 90 ingredients to give you the details you need.

Raspberry Ketone

There are dozens of plant extracts used in diet supplements. One of them is raspberry ketone, which is a chemical taken from red raspberries. It’s also used in some colas, cosmetics and ice creams to add flavor and/or fragrance.

What is it Supposed to Do?

This chemical is often added to supplements to help with the breakdown of fat cells. This way the body can burn off excess pounds more quickly. Furthermore, raspberry ketone may help boost adiponectin levels. This is a hormone that helps regulate metabolism.

Clinical Research

There is some evidence that supports this fruit chemical as a weight-loss aid. According to one study that was conducted with mice being fed a high-fat diet, “Raspberry ketone prevents and improves obesity and fatty liver.” This research has not been supported in human research.

Actual scientific research is an important part of the equation when searching for the right diet supplement. Therefore you might want to take a peek at Leptigen. This weight-loss formula contains ingredients that have been researched.


Also referred to as collagen hydrolysate, gelatin is basically a protein that is produced from animal products. It’s both colorless and translucent.

What is it Supposed to Do?

Well, typically gelatin is used to make the capsules for numerous supplements. This is the casing that holds in the key ingredients, vitamins and minerals. It dissolves in the stomach, releasing the inner components. However, it does not aid with weight management.

Clinical Research

We were unable to find any clinical studies that support the effects of gelatin for weight-loss. Put simply, this substance is used to create the outer shell of capsule supplements.

Magnesium Stearate

Sometimes called octadecanoic acid, magnesium stearate is a salt. It is a white powder substance that’s found in nutritional supplements, powders and medical tablets.

What is it Supposed to Do?

Often magnesium stearate is used as a lubricant for pills and tablets. Furthermore, this substance can affect the release time of key ingredients used in weight-loss supplements and diet pills.

Clinical Research

There is no clinical research that supports magnesium stearate as an effective weight-loss ingredient. On the other hand, “The 1985 edition of Pharmaceutical Technology has been used to suggest that magnesium stearate impacts absorption of nutrients.”

Is There Anything Out There That We Think TRULY Works?

There is one weight-loss supplement that caught our eye. Leptigen, which offers ingredients that HAVE been clinically tested, may be a solid option. All customers can benefit from a Special Trial Offer, currently available. Click here to give it a go.

    I ordered the slim 90 PM and it left a bad taste in my mouth so I sent it back. They have had it for almost a month and I haven’t received a refund yet. They keep telling me that it will be done in a couple of days! So Frustrated! I will never buy anything from this company again!!!

    Just a comment about the customer service. I am very frustrated with the whole process that it has taken to return the 3 month product that we accidentally purchased. We purchased 6 months by accident on the website, my husband said the amount had switched without him knowing when he ordered. He had wanted to only have a 3 month supply. So I called and they said that it would be taken care of, they would only send 3 months and credit our account. They sent out the full 6 months and even though I returned the 3 month supply, they can not find the package that I sent and have not credited my account as of today. It has been a 3 month process and multiple calls and they still have not found the package and have not credited my account. I am frustrated beyond belief and feel as if they are waiting for me to just give up.

    It is a joke…it does not work….I gained 10 pounds on this junk!!! I was dumb enough to let Lewis talk me into buying 5 bottles of LookSlim 90 PM + 5 bottles of Lookslim 90 AM. This was $309.80. Then last month I noticed a charged from Healthy Me in the amount of $57.90 & I called and told them that was not a authorized charge. I also contacted my credit card co…I see where I received a credit on this.

    Look Slim 90 – In February of 2012 you went into my bank account and stole $57.90 out of it. I have called you over 50 times and have been promised a refund and still to date 02/06/2013 have not seen it. I have been lied to over and over again about it being in the mail and now they won’t answer the phone. I assume they have caller I.D. as if I use someone elses phone they pick up. I will give you 1 week to return the money or I will find every page on the internet to let people know about this company stealing from bank accounts. Very unsecrue company. I HAVE BEEN MORE THAN PATIENT FOR YOU STEALING MY MONEY AND NOT RETURNING IT. OVER 1 YEAR ALREADY.



    Thanks Cathy this does it for me. I am not even goin to try the program. Thanks for the review!



    Thanks for the warning Cathy. I won’t order this for my husband. I’d rather try something from a company you can actually trust!


    Your Name

    Thanks for the heads up Cathy! I’m glad I read the reviews.
