Natural Trim Review - Does This Fat Burner Actually Work? Are side effects and discouraging user comments deal breakers?

By Summer Banks on Sep 15, 2016
Natural Trim Review

You may be surprised by what I say in this Natural Trim review. We dug deep and conducted a thorough investigation, examining the ingredients, side effects, customer-service quality and scientific studies. We additionally looked at numerous user comments and remarks from around the web. Lastly, we compacted all of the data we collected to give you the facts you really need.


What is Natural Trim?

First off, Natural Trim ingredients include caffeine, 3-acetyl-7-oxo dehydroepiandrosterone, evodia fruit, yohimbe bark, rhodiola rosea root, vinpocetine and black pepper extract. The directions say to take two-three capsules per day, along with meals. This supplement is claimed to help you drop three times more weight than diet and exercise alone. It’s also supposed to provide sustained energy and improve mental focus. You are encouraged to diet and exercise while taking this formula.

It’s unclear when Natural Trim was initially released. The company that makes this diet aid is Starlight International LTD. You can buy this weight-loss supplement directly from the main website. Also, there is a 30-day refund guarantee provided with this product. There are some user success stories posted on the website as well, but read on…

Side Effects – “Is It Safe?”

One concern we have is with Natural Trim side effects. According to our Research Editor, “Some users have reported adverse reactions such as rapid heartbeat, anxiety, headache, stomach pains, nausea, jitteriness and dizziness. Naturally this is concerning.”

One customer stated, “It will give you a boost, but gives me a bad headache as well.”

But, a different user said this, “Natural Trim helps curb my food cravings. I’ve lost a few pounds over the past few weeks.”

Another posted, “Makes me a bit jittery, but I do think it helps.”

Discouraging User Reviews – “Another Issue?”

Sadly we did find some negative customer comments posted on the web for Natural Trim 3x weight-loss pills. In fact, one person reported, “I don’t think this product works as claimed. Been taking it for three weeks now, and nothing.”

Then again, a different customer posted, “I would compare this to a cup of coffee or an energy drink. Wakes you up. Don’t take it near bedtime.”

Another commented, “It’s okay, but I won’t spend the $50 again. Not sure it’s worth that much.”

According to our research, if there is a specific part of a diet product or program that’s very burdensome or difficult (adverse reactions, discouraging user reviews, low Amazon star rating) the likelihood of long-term success is slim. In other words, if Natural Trim weight-loss pills do in fact cause unwanted side effects in a lot of people, this could be a serious issue.

The Science – “Solid?”

Firstly, there is clinical testing mentioned on the official website. However, from what we gathered, there is not much solid evidence that supports Natural Trim capsules for long-term weight-loss, other than that available for caffeine. Though, there is some support for black pepper extract that’s in its infancy. For us at DietSpotlight, we like to see some real science that backs up the diet product and it’s marketing claims.

The Bottom Line – Does Natural Trim Work?

So, should you whip out your credit card and order a bottle of Natural Trim? Well, we like that this supplement is easy to use anywhere, and it is sold with a money-back guarantee. On the other hand, we have some doubts about this diet product because several people have complained about side effects. Also, we’re concerned about other discouraging user comments we found posted on the web.

If you really want to get rid of some excess fat, then we recommend you select a product that does not cause any harmful reactions, is supported by numerous customer testimonials and contains clinically tested ingredients for weight-loss.

Among the best products we’ve seen in 2016 is one called Leptigen. This formula contains a combination of four unique ingredients, which have been shown in documented clinical studies to help speed up fat loss and spark metabolism. Also, we have not discovered any negative user comments at all, and customer remarks posted online express people are seeing real results.

The makers of Leptigen are so positive about their product they’re offering a Special Trial Offer, which is uncommon.

How Does Natural Trim Compare?

Previous Natural Trim Review (Updated August 29, 2015):

What You Should Know

Starlight is the manufacturer of Natural Trim. The weight loss supplement has an official website with before and after photos from dieters who claim to have lost weight taking the supplement. According to information on the website, the thermogenic complex can help the dieter to lose three times more weight than any diet and exercise program followed without the supplement. Direct supplement ordering is supported via the website, and customer service contact information is provided.

List of Ingredients

Chromium, Proprietary Fat Burning Complex - 3-Acetyl-7-Oxo Dehydroepiandrosterone, Evodia, Yohimbe Bark Extract. Proprietary Sustained Energy Blend - Rhodiola Rosea Extract, Caffeine, Vinpocetine and Bioperine.

Product Features

Aside from Chromium, which we can assume is the appetite suppressant used in Natural Trim, all other ingredients are listed as part of proprietary blends. Proprietary is a simple way to include ingredient names that may be proven and trusted without telling the dieter how much of the ingredient is added to the supplement formula. We tend to avoid products unwilling to share ingredient specifics. The first proprietary blend is the Fat Burning Complex. 3-Acetyl-7-Oxo Dehydroepiandrosterone, also known as 7-Keto is thought to promote weight loss without the side effects associated with DHEA. DHEA converts to 7-Keto in the body. Animal studies have proven a slight increase in weight loss, but animals has a far different genetic makeup than humans and no human trials have been completed regarding weight loss and 7-Keto. Evodia comes from a seasonal tree and if often used in alternative medicine to treat stomach ailments. Evodia is known to increase appetite, which does not help a dieter lose more weight. Yohimbe is a stimulant that increases heart rate. The Sustained Energy Complex in Natural Trim contains caffeine, a natural stimulant. Rhodiola Rosea Extract is a slight stimulant and mood elevator. Vinpocetine is an interesting ingredient that is often used as a memory-enhancing supplement. There is a long list of potential side effects from taking Vinpocetine including nausea, dizziness and anxiety. Bioperine is simple black pepper and is supposed to increase fat burn though this effect is not proven. Natural Trim sells for $50.00 for a one-month supply.

  • Ingredients are found online.
  • Stimulants may increase metabolism.


  • Vinpocetine is known to cause a long list of side effects.
  • Several ingredients in the energy complex are not commonly used for energy.
  • The supplement contains more than one stimulant.
  • Natural trim costs $50 per bottle.


If a dieter is going to pay $50 per month for a weight loss supplement, the claims made by the manufacturer should be proven. Testimonials and before and after photos do not always provide enough support for a supplement's claims to convince a dieter to spend money on a specific product like Natural Trim.

Evodia Fruit

The evodia fruit is grown on a tree native to China and Korea. It is used primarily in traditional Chinese medicines. It can also be used as an herbal alternative for certain treatment.

What Is It Supposed To Do?

Evodia has been used to treat a variety of things, including nausea, vomiting, obesity, high blood pressure, and infections. It is also used by women as a contraceptive.

Clinical Research

In a study published in Planta Medica, researchers tested the dietary effects of evodia on mice. In conclusion, they stated, “Evodiamine [a chemical in evodia fruit] would induce heat loss and heat production at the same time and dissipate food energy, preventing the accumulation of perivisceral fat and the body weight increase.” There are no studies published relating these effects to humans.

You may want to try out Leptigen, a weight-loss supplement with ingredients that have been clinically tested on humans.

Yohimbe Bark Extract

Yohimbe bark is grown naturally in Africa. It can be found in dietary supplements.

What Is It Supposed To Do?

Yohimbe bark extract has been proposed to help in the treatment of erectile dysfunction. However, it can be associated with some negative side effects, including high blood pressure, chest pain, upset stomach, and more.

Clinical Research

According to the National Institutes of Health, yohimbe bark has, “No effect on body weight; insufficient research to draw firm conclusion.”

Rhodiola Rosea Fruit Extract

Rhodiola is a plant native to the arctic regions in Europe, Asia, and Alaska. The root is most often used for medicines, but extracts from the fruit are also used, just not as much.

What Is It Supposed To Do?

Rhodiola rosea fruit extract has been used medically for treating cancer, diabetes, common sicknesses, irregular heartbeat, and high cholesterol.

Clinical Research

According to a study published in Nutrition Research, “These initial findings suggest that treatments of C aurantium + R rosea have actions on central monoamine pathways and have the potential to be beneficial for the treatment of obesity.” However, the research was performed on mice. No studies were done with rhodiola rosea fruit alone to test its individual weight-loss capabilities.


Caffeine is a stimulant found in many beverages, including soda, tea, and coffee. It usually has a bitter taste and is common in dietary supplements.

What Is It Supposed To Do?

As any other stimulant, caffeine can increase mental alertness, energy, and focus. Taking too much, though, can result in negative side effects.

Clinical Research

In a study published in Obesity Research, researchers concluded, “High caffeine intake was associated with weight loss through thermogenesis and fat oxidation and with suppressed leptin in women. In habitual low caffeine consumers, the green tea-caffeine mixture improved WM, partly through thermogenesis and fat oxidation.” However, NaturalTRIM does not contain enough caffeine to warrant these effects.

Is There Anything Out There That TRULY Works?

Right now, the makers have a Special Trial Offer available to all new customers, something we think you should take advantage of. Click here to learn more.
