Best Slim Review – How Safe and Effective is it?

While there are undoubtedly many diet pills that are known to be beneficial for not only weight management but overall health as well, there are also products out there that are known to be that in image only. These concoctions may look very similar to exceptional products, because that is there purpose. They rely on images and superbly written marketing copy to get people to buy them. Sometimes however they copy that is written on these products is not that good. There are grammatical errors abound and it seems as if you may be reading material that was written by someone who has English as their second language, or even that they are still in the process of learning it! Such is the case with Best Slim, which comes off to me as a company that should have done a bit more editing before publishing their text online. With the word “diet” misspelled as “died” and “health care professional” being written as “healthy care professional”, on the official website, these are just a few examples of obvious red flags. Just by this alone you already know there is something wrong.

But instead of just passing this up, I decided to write a full review on this product, so that you, the consumer, may be more aware of what a bad product looks like, so you may better avoid it in the future.

What is it?

Best Slim is a product that alleges that it may magnify energy levels, quash hunger pangs, accelerate the metabolic rate, decimate fat deposits and prohibit fat absorption into the body. And these are just how this product effects weight management! There are also declarations that this may govern cholesterol and blood sugar levels, as well as “antioxidant” and “result immediately”. These last two points it’s pretty obvious what they are saying, but I’m just taking verbatim what I see on their website. With grammar like this, it’s only natural to be skeptic.

Another reason to be a bit cautious about using Best Slim, is that in 2023, the company had to recall this product because the FDA (Food and Drug Administration) found sibutramine, a banned substance, in this product. This was specifically for the bottles of Best Slim that contained 40 capsules, which I still do find available for purchase from third party retailers.

EDITOR'S TIP: Combine this supplement with a proven fat burner such as Sletrokor for better results.

I’m not saying that the current itineration of this product still contains sibutramine, but I would exercise caution when looking into this product, as it has a history of rather seedy practices.

Who makes it?

CTV Best Group is the Duluth, Georgia based company that is known for manufacturing Best Slim. The company does feature an About Us page, but all there is to it, is an image that fails to load. No other information is provided about this company. From the looks of it’s official website, the company also sells other products that pertain to facial and hair care products, as well as supplements that contain antioxidants. Also strangely enough, it seems that you may be able to purchase Zippo lighters from their website, although the connection this has to wellness and overall health, I have no idea. The website itself is rather confusing, as half of it seems to be written in English, and the other seems to be written in Vietnamese. Furthermore, it does not seem that the company has a social media presence in any way.

Does Best Slim work?

While there are bullet points that market Best Slim to be an incredibly dynamic product, no where are there any clinical studies provided that would verify any of this being true. Just looking at the grammatical errors that are present in the text should give off more than a hint of what is to come with this product. If the makers can’t even spell words right, that’s never a good sign. While there are fabulously positive reviews that I was able to find on a third party supplier’s website, I did notice that of the five that showed up all of them were reviewed by people are marked as “Unknown”. This is hardly an example of something that may seem legitimate. Past these high rated, questionable reviews, I was not able to find any other independent reviews on this product.

Best Slim Ingredients and Dosage

There are 6 different ingredients that are mentioned to be found within Best Slim. Of these ingredients, there are no ingredient amounts listed, so we have no way of knowing which ones are truly competent substances and which ones are more used as filler if anything because they come in such small amounts. These substances include mulberry leaf extract, cassia seed extract, medical amylum, mustard extract, coicis extract and lotus leaf extract. Mulberry leaf is known to regulate blood sugar levels, while cassia seed has been known to be used as a laxative. While this may help with short term weight loss, it is not advised to use laxatives too much, as there may be dangerous health complications that may arise. Lotus leaf extract may have some relation to weight management while medical amylum is believed to prohibit fat intake. Mustard extract may enhance the metabolic rate and coicis extract may provide fiber to the body, which also acts as a laxative.

What makes this all a bit confusing, is this information that I was able to gather was from a third party supplier, not from the official website. Furthermore, in terms of dosing, there are two different amounts given, depending on where you are looking! The amount on the official website says to take 2 capsules a day, while the instructions on the third party website say to only take a single capsule a day. With such confusion, need I go into further detail about why this product is advisable to be avoided if anything?

I was unable to find a supplement label for this blend.

Are there potential side effects?

Best Slim is known to operate through the use of laxatives, which is not the safest route to weight loss. Health complications may arise from dependence on such substances, which may be incredibly detrimental to overall health. Severe dehydration may result from abuse of such substances, as well as blurred vision, kidney damage, tremors, fainting and in rare extreme cases, even death.

When looking over the product descriptions of this concoction, it is stated that there are no adverse reactions that are associated with use of this product, but with ingredients that are known to be laxatives, it seems that this may not necessarily be so. In the past, Best Slim was also known to contain, sibutramine, which was known to cause serious adverse reactions in the people that used it.  These side effects include, dilated pupils, nausea, hallucinations, arrhythmia (irregular heartbeat), shortness of breath, palpitations (rapid heart rate), vomiting, loss of coordination, diarrhea, fever and agitation. It is unknown at present time if this blend still does carry the banned substance, but it is important to stay aware of the symptoms that may potentially be experienced.

Top Rated Products would never hide illegal substances within them.


Just a look at the poorly written product descriptions should in itself be enough to deter people from purchasing this product. And that’s notwithstanding that Best Slim was known in the past to carry within the illegal substance, sibutramine, within it. It may not be within the product now, but there always is a level of uncertainty that arises. Going back to the poorly written descriptions, it really feels harder to trust that any of what is said about this product is indeed true. There are a lack of clinical trials that aren’t so much as mentioned which pushes the legitimacy of this concoction even further away from the realm of believability.

With two separate website asserting different directions as to how to take Best Slim, it’s as if the makers of the product itself are confused as to what they even created. If there was ever an clear example of a diet pill that should be avoided, this would be it. There is no way of knowing if what is said is truly valid or not, plus this may even be dangerous to consume. The only thing you should use this product for, is as an example of what to stay away from when you are shopping for weight management products.

Top Rated Products would come off as the exact opposite of what this example has demonstrated.
