Avesil Review - Does This Weight-Loss Supplement Work?

By Summer Banks Sep 07, 2017

Don’t laugh, but well over 50% of diet products simply don’t work. So what about Avesil? We at DietSpotlight conducted a thorough review, investigating the ingredients, side effects, clinical research and overall customer service. We additionally looked at countless dieter comments and user experiences from all over the web. Finally, we compressed all of the facts and feedback we collected to give you the important information you need.

What is Avesil?

First off, Avesil is marketed as a fast and safe weight-loss formula for women and men. This supplement assists by reducing appetite, boosting energy levels and burning off unwanted body fat. It contains four key ingredients, which include Meratrim (400mg), Green Tea Extract (200mg), Chromium (100mcg) and Natural Caffeine (75mg). This product aims to boost thermogenesis so your body burns off more calories and fat. One capsule of Avesil is a serving, and this product can be taken twice daily, 30 minutes before meals for maximum results. While it is not mandatory, you may see better weight-loss results if you follow a healthy diet plan and exercise at least three times a week.

Avesil was originally released back in 2008, and this supplement is readily available online through the official website and on Amazon. Furthermore, you can receive a 14-day trial of Avesil for only $5.95 if you fill out your name and address on the official website, but read on…

Mild Side Effects – “A Consideration?”

The first minor issue was with Avesil side effects. According to our Research Editor, “There have been a few minor complaints about mild reactions. For instance, some users mentioned stomachache, nausea and intestinal discomfort.”

“It seems to work, but it gave me a slight tummy ache,” said one user.

Another customer commented, “Definitely reduces my appetite, but causes a bit of nausea as well.”

Lack of Availability – “Not in Stores?”

Some dieters will be disappointed that Avesil is not sold in stores. It must be obtained online. One person stated, “It would be nice to see this product available in drugstores, but it’s apparently only sold on Amazon.”

“You have to buy Avesil online, which is kind of disappointing. I prefer when products are available locally,” mentioned another individual.

The extensive research we’ve done has shown if there is a certain facet of a diet program or product that is quite concerning or bothersome (mild side effects, lack of availability, bad taste) the probability of lasting weight-loss results is low. In other words, if the fact that Avesil is not found in stores does bother a lot of people, this could be a real problem.

Is There Any Solid Science?

At DietSpotlight, we need to see some real clinical research that supports the weight-loss product. Fortunately there are some solid clinical studies that back the claims regarding Avesil ingredients. The four key pieces of the formula are part of valid clinical studies, which is certainly reassuring.

The Bottom Line – Does Avesil Work?

So, should you buy Avesil? Well, first and foremost, we appreciate that Avesil contains clinically tested ingredients that are completely natural. On the other hand, it’s unfortunate that this weight-loss formula is not readily available in stores. Then again, we like that it is suitable for women and men trying to lose weight, and it’s easy to find on major websites such as Amazon. There are even some customer testimonials posted on the official website.

If you’d like to get rid of some serious pounds, we suggest you go with a diet product that is backed by solid clinical testing, does not cause any harsh side effects, based on user review, and is easy to use anywhere.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula is a unique but powerful blend of four key ingredients that have been shown in published clinical testing to help ignite metabolism and speed up fat loss. You should also be aware that we found few complaints of side effects and the customer feedback posted on the web indicates people are seeing solid results.

The makers of Dietspotlight Burn are so satisfied with their product they’re offering a Special Trial Offer, which is a good sign.

Previous Avesil Review (Updated May 1, 2014):

What You Should Know

avesil-bottleAvesil is an innovative new thermogenic weight control product designed to increase your metabolism and reduce body fat percentage. The first thing we noticed was that the company has clearly gone to a lot of effort and expense in research and development. Avesil’s primary ingredients include, Meratrim (recently featured on Dr. Oz), which is a metabolism booster, as well as the fat burner Chromium and Green Tea Extract which also speeds up your metabolism and helps you continually burn fat. Get started with Avesil today by clicking here. It was refreshing to see a weight loss supplement with product claims so deeply rooted in real science, instead of the usual fluff.

How Does Avesil Work?

Avesil has been formulated to work on the basis of thermogenesis - the process that increases the rate at which fat is burned. Currently, research on the process of thermogenesis within the human body has captivated the diet aid industry, and many see understanding this process as the key to developing effective weight loss supplements. With this in mind, the makers of Avesil have included only thermogenic ingredients backed by scientific data showing how the ingredients help support a healthy metabolic rate. The result is a formula which causes your body to burn food as energy, rather than storing it as fat. These ingredients also help suppress your appetite and break down stored fat, a process called lipolysis.Additionally, Avesil claims that it does all this while helping to preserve and maintain lean muscle mass. One of the issues users have found with many weight loss supplements is that they draw water off of the muscles, making it difficult to maintain a healthy overall physique. Avesil seems to do a good job answering this challenge.Finally, regarding our last review criteria -- company customer service -- our experiences with Avesil have been positive. Filling out the trial offer is simple- just enter your address in the "SHIP MY TRIAL TO:" form. With other products, we've had to wait on hold for 20 minutes or more, but several test calls to Avesil customer service were always answered under the 1:00 minute mark. We canceled our order easily, and got both an email and phone confirmation of cancellation.

Product Features

There are only four ingredients in Avesil, and the simplicity of the formula seems to work much in the product's favor. Many other diet supplements include lots of filler ingredients of questionable efficacy that accomplish little when it comes to weight loss. A trick favored by many manufacturers is to include literally dozens of individual ingredients, though in such small amounts that they don't actually produce any benefit, but still look impressive on the product packaging. In these cases, you end up paying for exotic-sounding ingredients that don't do anything except take up space. We were happy to see that with Avesil you are getting only proven dietary ingredients in exact dosage quantities which are consistent with dosages administered in the most significant published research studies that back up the product claims. The four dietary ingredients in Avesil are: Patented Meratrim, Green Tea Extract, O-polynicotinate Chromium, and Caffeine. Here are some of the highlights of how each ingredient works.Patented Nutraceutical Meratrim:1) It is a metabolism booster that has been shown in clinical trials to help people who followed diet and modest exercise programs lose 30 pounds within 90 days. 2) Supported by randomized, double-blind, placebo controlled human clinical trials.Green Tea Extract:1) Has been shown in clinical trials to product up to 3 times the weight loss of just a reduced calorie diet program when taken with a similar diet and moderate exercise program. 2) Has been shown in clinical trials to accelerate weight loss after 45 days 3) Increases energy. 4) Supports stabilized blood sugar levels, which can help those with both blood sugar and weight control issuesO-polynicotinate Chromium:1) Helps control blood sugar and glucose tolerance within normal levels. 2) Supports conversion of body fat to energy when working out.Caffeine (it should be noted that the modest amount of caffeine used in Avesil has been shown to produce the following effects without an unpleasant “jittery” feeling): 1) Increases production of ATP (adenosine triphospate), a key in energy production. 2) Stimulates the metabolism of fatty acids. 3) A mild stimulant, increasing energy. 4) Enhances neuromuscular coordination and motor performance.

There are hundreds of weight loss products on the market that make a lot of promises. The Avesil formulation reflects a massive amount of scientific research to certify the product claims, all without added fluff ingredients that cost extra money and do nothing for you. By using only thermogenic and cortisol-reducing ingredients, Avesil appears to provide an effective, safe way to maximize the results of healthy diet and exercise. The manufacturers don’t claim that this will work without some effort on the user’s part, but it will certainly boost any weight loss efforts. In addition to its simple and well-researched product formula, Avesil seems to have superior customer support. All of our calls to their customer support center went through quickly, compared to 20+ minute hold times that we've experienced with other product's help lines. The $3.95 that you spend on shipping gets you a professionally mailed and packaged product; it's affordable and costs about the same as a latté-a-day habit. We tried three sample orders before writing this review and, two times, it took three business days (during the work week) and one time it took five business days (order placed over the weekend) to get to our office. The product's manufacturer references a large amount of published research to back up their product claims, and they also offer a trial for consumers to try the product without having to pay for it if they aren’t happy. We can’t find any other product capable of competing with Avesil on all of these levels, making it our top choice for a weight-control product.Click Here to Buy Avesil

Hello, I have a hard time taking pills and either have to crush them or open them and put them in yogurt or small amounts of food. is it safe to do that with this product?

Victoria (Editor)

Hi Amber,

We recommend to take the pill in its whole form as instructed so that the key ingredients can be released into the body in the time they were designed to be released. Consult with your doctor if crushing the pill would be safe for you if you absolutely cannot take the pill in its whole form.
