You’re about to learn everything you need to know about the fat-binding supplement Proactol XS. We took a deep dive into ingredients, side effects, and clinical research. We analyzed hundreds of consumer comments and reviews. We then refined and summarized to give you the info you need.

What is Proactol XS?

To begin, Proactol XS is a dietary supplement containing chitosan. The recommended serving is two capsules before a meal, which supposedly reduces food cravings. One of the benefits is you can take the pill on the go.

The supplement, introduced as a fat binder in 2005 by Bauer Nutrition, doesn’t appear to add artificial ingredients, a good decision. You can shop for the product on the official website and retail sites. We do like that the company has been in business for ten years and that we found some positive customer comments, but read on…

Constipation – “I’m Stuck?”

The first negative relating to Proactol side effects was constipation. “Maybe you don’t want to talk about it, but it happens to us all,” said our Research Editor. “Getting bound up by a weight-loss supplement is not something you have to settle for.”

“I can safely say I will never be trying Proactol again! I started taking them and rather than weight loss all I experienced was really bad constipation. I drank as much water as I could to try and ‘smooth things out’ but it was no help,” commented a customer.

“When they say “constipation” is a side effect of this product, they are not kidding. Plan on drinking HUGE amounts of water (well over eight glasses a day),” said a dieter.

Effectiveness of Proactol – “Does It Really Work?”

Another issue is that some customer comments say Proactol ingredients aren’t useful. “I have dieted for two months now and taken these tablets that entire time. It’s very disappointing and disheartening. This product had no benefit for me, I’ll have to keep looking,” commented a customer.

“So far I’ve been taking Proactol for a couple of weeks and I’ve yet to see any real effects,” reported a dieter.

“I’ve been taking Proactol for 6 whole months. I’ve kept going in the hope that it is just a slow working pill and the weight loss will eventually pick up but now after six months I’m considering giving up. I’ve not really seen any major effects and no dramatic weight loss so I don’t know how effective it is,” said a user.

Our research has found if there’s an issue with a product, like ineffectiveness, there’s a slim chance of long-term success. If Proactol Plus doesn’t live up to the hype, dieters will leave it behind.

The Science – “Anything Proven?”

Based on the official Proactol website, the supplement is “clinically proven,” yet the company doesn’t provide scientific evidence to support the claims. We found research stating the active ingredients in Proactol are ineffective. According to the Journal of the International Association for the Study of Obesity states, “results obtained from high-quality trials indicate that the effect of chitosan on body weight is minimal and unlikely to be of clinical significance.” At DietSpotlight, finding studies to link the formula to weight-loss claims is imperative. If a company can’t provide proof, we have concerns.

The Bottom Line – Does Proactol Work?

So, what’s the final take on this one? After taking a hard look at Proactol Plus, we’ve reached a conclusion. There are some positives like the time the company has been in business, and we located a few favorable customer comments, but we are hesitant about recommending it because there’s no published scientific research supporting weight-loss claims. We also find the reported side effects to be a little concerning.

If you want to drop extra weight, we recommend going with a product with no known side effects, with a formula supported by published clinical research.

Among the best products we’ve seen this year is one called Dietspotlight Burn. The formula consists of a four-ingredient proprietary blend, which has been shown in published studies to help promote fat loss and enhance metabolism. Dieter’s aren’t mentioning harsh side effects, and reviews on the web show people see excellent results.

The company that makes is so confident in Dietspotlight Burn that they’re offering a Special Trial Offer.

Previous Proactol Review (Updated June 13, 2014):

What You Should Know About This Proactol Review

The manufacturers of Proactol tell us that it is a daily supplement which will help reduce your body weight. They say that it will burn off to 28% of your fat intake and also reduce your food cravings. They go on to tell us that their product not only helps you lose weight, but that those who have taken Proactol have also experienced greater joint flexibility, lower cholesterol, and higher energy levels. Sounds like a miracle! The main active ingredient is Proactol is a patented fiber complex known as Neopuntia.


The main active ingredient in Proactol Plus is a patented complex called Neopuntia, which is derived from the Optuntia Ficus India Cactus. Optunia Ficus India is also more commonly known as Prickly Pear, and has since been cultivated to grow in other climates.

Product Features

There is a very detailed official website for Proactol. It can be ordered directly on line for a price of $89.95 for one hundred and twenty tablets. When you order Proactol you also receive a free toning belt. The official website also states that there is a one hundred percent money back guarantee. The manufacturers advise that three to four Proactol tablets should be taken after each meal. They also say that those who have kidney disease, are breast feeding, or are taking medication for high cholesterol, should seek medical advice before taking Proactol.

Prickly pear which is the main active ingredient in Proactol is said to have weight loss properties. The Prickly Pear plant is rich in Vitamin B1, Vitamin B6, Niacin and Pathothenic Acid. The manufacturers say that it is one hundred percent natural. The manufacturers present us with a number of clinical trials on the website claiming that Proactol and its active ingredient Neopuntia do help to stimulate weight loss.


  • There is an official website for Proactol RX.
  • You can order the product directly on line.
  • There is a free gift with purchase and also a money back guarantee offered by the manufacturer.


  • Prickly pear, when taken too often, can cause stomach problems.
  • This product may not be suitable for those who have kidney problems or high cholesterol.
  • Those who are breast feeding will need to seek medical advise before taking this product.
  • Proactol does not seem to contain any unique proprietary ingredients that set it apart from other weight loss supplements.


There are a number of things in favor of this product. For starters, there is a money back guarantee and a very detailed website full of information. The official website also presents us with the results of clinical trials that do seem to indicate that the product will help result in a certain amount of weight loss. However there are other products on the market which will also help users to achieve this weight loss. The question we are concerned with is whether Proactal is actually superior to other weight loss products on the market. Considering that the manufacturers recommend taking three or four pills after each meal, undertaking a full Proactol Plus course could become tedious. We also have some hesitations about consuming that quantity of prickly pear essence, since this can result in negative health effects in some users.

Proactol Side Effects:

Proactol is a dietary supplement that supposedly blocks the absorption of fat; similar to the products like Alli. If you eat higher fat foods, the excess is eliminated from the body in the form of waste.
