Slimfy is a controversial weight loss brand claiming to offer a full three stages for maximizing weight loss. Three different brands are offered, each one claiming to help provide unique weight loss benefits, though this has not been proven.

Stage one is for detoxifying, stage two claims to enhance weight loss, and stage three maintains weight reduction. It’s said to be effective for improving metabolism, mood, fat burning, energy, and motivation. Diet and exercise are advised in order to experience the full effects. It’s possible to purchase each bottle individually, but it’s built as a total weight loss experience. This controversial company was poorly reviewed by consumers and they tried to deny consumers this review by attempting cyber-attacks to our website. They are serious scammers which many consumers said were difficult to deal with who forge their positive reviews.

After reviewing several weight loss supplements we concluded that Sletrokor was the best for weight loss. We favored its natural formula and high dosage strength which consumers often had good things to say about. For more information on Sletrokor you can examine our official review here.

Unethical Behavior and DDoS Attack Attempts:

UPDATE: We had to update this review after Slimfy owners launched what is known as a DDoS or cyber-attack that scammers use to make a website no longer usable. This means that instead of improving their long history of scam like practices, they instead want to deny consumers the knowledge of their shady business practices through reviews like this.

On 3 separate attacks they tried to bring down our website to prevent consumers from knowing the truth about their scams.

Here’s an example of message that we received from Slimfy owners:

We hope that those scammers will enjoy this updated review on Slimfy diet pill.

Slimfy Ingredients and Side Effects 

Here are the ingredients to all 3 of the supplements:

Green Coffee Bean Extract Hydrangea Root Milk Thistle Seed Organic Ginger Root Saffron Extract
Raspberry Ketone Extract Resveratrol Organic Maqui Berry COQ10 Organic African Mango Extract
Green Tea Extract Caralluma Fimbriata Lychee Extract

Green Coffee Bean Extract: Unroasted immature coffee beans used to decrease appetite and to help with fat burning.  Since it contains caffeine, it’s possible for it to lead to side effects such as:

  • Rapid heart rate, irregular heartbeat, and cardiovascular damage.
  • Vomiting, nausea, and upset stomach.
  • Ringing in the ears, anxiety, and agitation. 

It’s unknown exactly how much caffeine is added to this brand. There’s no way to determine the total caffeine content, its’ impossible to determine if it’s included in safe amounts.

People have different reactions to caffeine, and this can cause serious problems in certain people. Also, caffeine is not considered an effective weight loss ingredient. Many of its effects are diminished with repeat use. Often the only benefit to caffeine will be increased energy and focus, but habitual use can cause withdrawal effects.      

Hydrangea Root: Plant extract used to help reduce urinary problems; it also acts as a diuretic.

It can produce many possible side effects, and Web MD adds:

“LIKELY UNSAFE to use hydrangea for long period of time” 

Possible side effects may include:

  • Dizziness, nausea, and vomiting.
  • Chest tightness and agitation. 

Our research team has compiled a top 10 list of the year’s best weight loss supplements.

Milk Thistle Seed: Plant extract used to produce many effects such as to improve blood sugar, and to support liver health.

Studies have shown it to be the highest mycotoxin plants, meaning it may have toxic effects in the body. In animal studies it was shown to block oxygen transport, which can lead to death.

There’s no information provided by the makers of Slimfy to suggest they have treated this ingredient to get rid of its mycotoxins. 

Saffron Extract: Plant often used as a spice. Though it’s claimed to have numerous health benefits, Web MD adds:

“There isn’t enough information to know how saffron might work” 

There are also safety concerns. Web MD mentions:

“Taking large amounts of saffron by mouth is POSSIBLY UNSAFE” 

Possible side effects are many and they can include:

  • Yellowing of the skin and eyes.
  • Poisoning.
  • Numbness.
  • Vomiting and dizziness.
  • Allergic reactions.
  • Dry mouth and nausea.
  • Bleeding from the lips, nose, and eyelids. 

Large amounts may potentially lead to death. 

COQ10: Energy source used by the mitochondria in the human body. mentions:

“does not necessarily need to be supplemented” 

“There is no evidence that COQ10 improves life expectancy or is able to induce fat loss” 

Since it’s already produced by the body and it’s found in many foods, it’s not considered a necessary ingredient. When supplemented it’s possible for there to be no benefit at all. 

Green Tea Extract: Common tea made from the Camellia sinensis plant, it contains more antioxidants than the black or white tea.

Caralluma Fimbriata: Succulent plant used to help decrease hunger. Possible side effects can include:

  • Constipation, stomach pain, and gas. 

Web MD also mentions:

“The long-term safety is not known” also mentions that it can take up to a month for there to be any appetite suppressing properties. Though since only one month long Slimfy bottle has this additive, it’s not enough for it to produce such an effect.

Our featured top 10 list has some of the most highly regarded supplements for weight loss.

Slimfy Quality Of Ingredients 


Many of the ingredients including COQ10, saffron, resveratrol, and others have not been seen as necessary, since either they’re not yet proven, or they can be already found in foods.

Then there are ingredients like green coffee bean and saffron which may be potentially unsafe.  It’s unknown how much caffeine comes from either green tea extract or green coffee bean. It’s very important to determine this amount, as repeat use of caffeine can promote many unwanted side effects.

The ingredients included are commonly featured in many other weight loss supplements. There’s no indication that this brand is more suitable for weight loss than any other standard supplements.

Several of these ingredients lack evidence to prove them to be either effective or safe.

The Price and Quality of Slimfy 

When purchased via the manufacturers, 3 bottles lasting a month sell for $261.90.  

Many of these ingredients are cheap to purchase on their own, and this brand does not add any unique additives to their formulas.

This brand is one of the most expensive supplements on the market, and though it’s said to work in stages, there’s no proof that this is really necessary. Many of these ingredients are added to other supplements in just one bottle. There’s no reason to believe it’s better to separate these additives.

Also, claims of it sustaining, detoxing, and promoting weight loss are not yet proven and likely fraudulent.

The best weight loss pills are highlighted in our experts top 10 list.

Customer Opinions of Slimfy 

Many reviews are available on Slimfy. Here’s some customer reviews listed on their webpage:

“I have not lost anything” 

“These products did nothing for me” 

“This did not work for me” 

“Very costly. No difference” 

Though there were some positive reviews listed online, one customer mentions:

“some of the same exact word for word reviews” 

This customer read through all the positive reviews, and concluded that it’s likely these are not real. This is due to the similar sounding reviews which copy the exact same claimed benefits in the same style of writing and tone. After analyzing these reviews it’s clear that this is a likely scam the company uses.

Conclusion – Does Slimfy Work?

When considering a supplement like Slimfy, it’s important to examine how the company operates, customer reviews, and what kinds of ingredients are added.

Sade Badmos says:

I did not experience any weight loss. It made me feel restless. My food cravings, if anything, increased.

Von says:

Thankee for the text!Suzanna don’t like it their customer support is worthless!
My friend Suzanna had a disgusting effect to this product with problems in digestive system and had an issue delivery.

Katherine says:

Be careful with this company! They charged my credit card without my authorization to deliver the Stage 3. The money back guarantee is not true. This product didn’t work at all!

charissa angela says:

they did the same with my card too! do you know how to get our money back?

Gretchen says:

Have experienced this. I just emailed the company about my complaint and they have refunded me. Thank goodness.


This company has charged my credit card without any authorization for Stage 3.

I still have all the prdocucts unused.

Not ethical at all.

Trupti says:

I just purchased it today online at 28.94$ at around 4:41 pm & I had not purchased it again but I got a text saying they deducted another 87.30$ for the second stage..why without me even knowing abt it

Beverly says:

I was sucked into a “FREE TRIAL” – the next day I noticed $112 had been deducted from my credit card. The company said it was for Stage 1 and 2 – Interesting, as I did not sign up for this but was willing to pay the $49 if I kept the product. I complained but unfortunately didn’t know that I had to put it legally that I wanted to delete my account.
One month later I was charged $126 for Stage 3 – again complained and was told I should have read the small print. THIS IS A MONEY GENERATING SCAM. I have tried Optifast and had better results. Do not get involved with this company. You will need to close your account to stop them from debiting every month forever.

Mike says:

Hi Beverly,

Thank you for this information. I have a similar experience where I subscribed to their free product trial which I agree to pay only for the shipping of the product with a cost of only $18.94. The next day they send an email saying that NS2 was included in the package and USD87.30 was charged to my credit card without my authorization. This surprised me since I did not agree to have NS2 included in the package and I definitely did no agree to pay USD87.30 for it.
I followed your suggestion to close my credit card account.
I wanted to know if I can get my USD87.30 back from them. Did you try asking them to return your money?

Derek Collins says:

I have just been scammed by them, I paid 18$ for a free trial and so far in 5 days they took 5 transactions totaling 132 euro and I have not received any product from them. I have cancelled my card. Huge scam!!

charissa angela says:

they did the same with my card too! do you know how to get our money back?

Ben says:

Anonymous says:

I ordered the free sample for $18.00 and they took money from my credit card for stage 1 and stage 2 which I did not order. Spoke to them on the telephone and they told me to return the items which I did immediately and it is almost one year now and I still have not gotten back my money of $152.00. I have sent several emails that they haven’t responded to. Their products are no good. THEY ARE SCAMMERS SO DO NOT USE THEM. CUSTOMER SERVICE STINKS.
