Look Slim 90 Review - 6 Things You Need to Know


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.

What is Look Slim 90?

To start, Look Slim 90 is a dietary supplement. The ingredients are collagen protein and 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.

Look Slim 90 was created by Healthy Me, Inc. around 2013. You can only buy it from the official website. We like that some users reported 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 person on the phone. My shipment hadn’t arrived and I called to see why. Never received an answer,” offered a customer.

“I returned the 3 month supply, they can not find the package that I sent and have not credited my account as of today,” said another.

On the other hand, we found that some customers had better experiences dealing with the customer service team.

“Called the 800 number and reached an agent within a few minutes,” said a consumer.

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 lost only three pounds,” reported a dieter.

“It is a joke…it does not work…I gained 10 pounds,” commented another.

Lack of results wasn’t an issue with some users. “Lost a few pounds. It made we look at food differently,” said a customer.

“Not dropping a ton of weight, but I did lose some,” stated a dieter.

Our research shows that if a weight-loss supplement is connected to anything negative, like lack of results, the chances of long-term success is limited. So, if Look Slim 90 doesn’t help you lose weight, is it really worth your time?

What Does Science Say About Look Slim 90?

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.

What Users Are Saying

"”Haven’t finished the book yet, but it is loaded with information. Dr. Fife is the authority on anything coconut, but here, he also shows his knowledge about chemistry of foods and elements in our bodies, such as cholesterol. Looking forward to completing the book and following his advice.”"

"”Great book. could not find it anywhere else.”"

"”In my opinion, ANY book by this author is outstanding but the market is so saturated with weight loss books it’s hard to sift thru the overwhelming amount of information. I have not used coconut oil for weight loss but the title intrigued me.”"

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 this year is one called Dietspotlight Burn. 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 Dietspotlight Burn are confident enough in the supplement to offer a special trial offer, a great sign.

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 Dietspotlight Burn. 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. Dietspotlight Burn, 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.

Previous Look Slim 90 Review (Updated March 11, 2014):

Look Slim 90: What You Should Know

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 in Look Slim 90

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.

Advantages of Look Slim 90

  • Supplies a source of protein.

Disadvantages of Look Slim 90

  • 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.

    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. Followed your way of taking it too.
