Proactol XS

Proactol XS is a fat binder supplement, that according to the advertising will help you lose weight quickly and safely. It contains Chitosan, usually derived from shell fish but in this case is derived from fungus, so is suitable for vegetarians. Proactol XS is not the same supplement as a previous product on the market called Proactol Plus.

Proactol XS is only on sale from Bauer Nutrition, a supplement retailer with a red cross logo that looks as if it should be a company based in Switzerland, but seems to be based in Larnaca Cyprus. Bauer Nutrition both produces their own supplements as well as stock other brands. There is no information about which category Proactol XS falls into.

Proactol XS Pros

  • Unlikely to cause major side effects

  • Suitable for vegetarians

Proactol XS Cons

  • The evidence for chitosan as a fat binder is conflicting
  • Misleading claims in the advertising about clinical testing
  • Unlikely to work as well as claimed

What You Need To Know About Proactol XS

Proactol XS is a fat binder that contains chitosan derived from fungus as the sole ingredient. Proactol XS is not the same supplement as Proactol Plus, a fat binder marketed by a different company which contained a cactus fibre. This has led to confusion for some customers, especially as Proactol Plus is no longer available. That said Proactol XS does not look very impressive. The clinical evidence is not outstanding for chitosan, and although the product advertising claims that this supplement has undergone 40 clinical trials there is no evidence that this is true.

What Are The Side Effects Of Proactol XS?

Potential side effects may include; gas, constipation, stomach upset, and nausea.

How Much Does Proactol XS Cost?

Proactol XS is expensive and although you can buy this supplement worldwide, all prices are solely in USD.

1 x 60 capsule tub of Proactol costs $49.95.

Each tub contains 60 capsules, which if you take as recommended (up to 6 capsules a day, it will only last you 10 days.

You can make savings on larger orders.

If you buy 2 x bottles you get 1 free bottle. So this option costs $99.00 for 3 x bottles.

If you buy three bottles, you get three free bottles (6 bottles in total). This option costs $149.85.

Worldwide shipping is free.

Our Verdict On Proactol XS

We are not overly impressed with Proactol XS. This weight loss supplement seems a bit lacklustre, and is unlikely to really help you lose much weight. We are frankly appalled that the advertising claims that Proactol XS has undergone 40 clinical trials, when it so obviously has not. In addition, the research into chitosan has displayed a wide variety of results, with some testing suggesting it is effective and others stating the weight loss is minimal at best.

We are not impressed that to take Proactol XS as recommended, your 60 capsules bottle could only last 10 days, making this supplement very expensive especially if it does not work. Even the Daily Mail article about a celebrity endorsing this supplement, only mentioned losing 4lbs in weight so it does not seem very effective.

Finally, there is something a bit shadowy about this supplement. It is only on sale via Bauer Nutrition rather than stocked by other retailers, and there is no independent feedback available. Even the so called guarantee is questionable; it is supposed to be valid for 60 days, yet the terms and conditions tell a different story.

Frankly we are sceptical about chitosan and until some concrete evidence comes along about this ingredient, we just cannot approve supplements such as Proactol XS which contain only this ingredient.

Overall, we do not recommend Proactol XS to our readers.

Proactol XS Review

Proactol XS is a fat binder, so may suit you if you struggle with too much fat in your diet. A fat binder will only work on fat, so if you eat a lot of carbs or sugars for example, this weight loss method will not help. However fat can be a major contributor cause to weight gain and many people do lose weight using this method.

Fat binders contain certain types of fibre, that when ingested trap dietary fats and make them pass through the system as waste. One of these fibres is Chitosan.

Proactol XS Facts

  • Proactol XS is not the same supplement as similarly named fat binder Proactol Plus
  • Each bottle contains 60 capsules – only 10 days supply if you take as recommended
  • Only on sale from Bauer Nutrition a supplements company based in Cyprus
  • UK customers can return unwanted supplements to Glasgow

Proactol XS contains Chitosan as the active ingredient. Chitosan is a fibre usually derived from sea shells and exoskeletons of shrimp and crab which are high in glucosamine. However this substance is also present in some types of fungi, and can be produced by fermenting some types of wheat and grain.

Proactol contains chitosan derived from Aspergillus Niger Mycelium. This is a black mould that adversely affects fruit and vegetables, and it is a waste product derived from citric acid production.

According to some clinical studies, Chitosan may be an effective fat binder, helping to reduce body weight by 3 k over a 90 day period.

How to Take Proactol XS

  • Take 2 x capsules 15 minutes before a meal
  • Take with a large glass of water
  • Use up to 6 capsules a day; 2 capsules before each meal

Proactol XS has been featured in the Daily Mail, which covered a story about minor celebrity Mischa Barton who used Proactol XS to lose weight. She reported losing 4lbs in a week and reported no side effects. Although we are impressed by Proactol XS making it into the national press, 4lbs weight loss is not quite as awe inspiring. There was no follow up story to say whether Mischa Barton’s weight loss continued, or if she was paid to endorse this supplement. Source

Proactol XS Concerns:

  • The guarantee policy. Will you really be able to obtain a refund within 60 days? The terms and conditions advise only 14 days
  • The so called clinical evidence quoted in the advertising, does not seem true. We can find no record for 40 clinical trials being carried out on Proactol XS
  • Confusion for customers between Proactol XS with Proactol Plus. These are not the same product

We covered the similarly named Proactol Plus in a previous Watchdog review. Proactol Plus, also billed as a fat binder, was derived from a cactus based fibre called Opuntus Ficus India (Prickly pear). However Proactol Plus is no longer available for sale and was not a Bauer Nutritional supplement. Despite the similarity of the two names, there seems to be nothing to link these two products.

Bauer Nutrition has the look of a major supplements company. It provides contact details for customers and we were impressed with the live chat facility on the website, finding the customer service operatives helpful. The company provides full contact details too, such as an address in Cyprus and contact phone numbers.

However it is important to note that Bauer Nutrition sell only via their own website and despite sounding like a household name, really is just yet another online supplements company despite looking a lot more professional than most. Other supplements stocked by Bauer Nutrition include
Meratol, another product we have previously covered.

You are highly unlikely to find Bauer Nutrition supplements on sale in any shops or stores. The company is based in Cyprus and ship worldwide. There is a wide range of supplements regarding general health, weight loss, and sports nutrition.

What Does Proactol XS Claim To Do?

According to the advertising,

Proactol XS is a medically certified fat binder which enables you to lose weight effectively and easily by reducing your fat intake.

It explains how the supplement works,

Proactol XS contains a natural source of fibres that bind fat from your food into molecules too big to be absorbed by your body. By reducing your daily fat intake, Proactol XS allows you to lose weight quickly, effectively and safely, whilst still enabling you to enjoy your favourite foods.

There have been clinical studies carried on Proactol. The advertising reads,

Backed by over 40 clinical studies showing it to be more effective than any other fat binder, Proactol XS is a natural, safe and powerful weight loss solution.

Does Proactol XS Work?

Worryingly, we cannot find any record of these 40 clinical trials carried out on Proactol XS. We would have expected at least one of these clinical trials to have been noted somewhere, but the only references to this impressive sounding clinical evidence are provided by the advertising.

There have been clinical trials carried out on Chitosan, but this is not the same as claimed by the advertising which clearly implies that Proactol XS, and not Chitosan, have been tested.

In truth, the evidence for Chitosan is conflicting.

One clinical trial looked at a supplement called Ki Onutrime, also based on Chitosan derived from fungus. This was a 90 days clinical study conducted in India. Participants took 500mg of chitosan in capsules five times a day.

Conclusions suggested that over 90 days chitosan did reduce overall body weight in the control group. This included the reduction of muscle mass on average 0.74kg and on average 3k of weight. Source

Other clinical trials have not been as impressive. An independent study followed similar serving size and duration found that,

The fat trapped was clinically insignificant. For men, it would take more than 7 months to lose 1 pound of body fat. For women, no fat was trapped. This product, as with other similar products, fails to meet claims.


Other studies have had similar underwhelming outcomes. Scientists suggest that the better the quality of the trial, the less impressive the results!

What Are The Ingredients of Proactol XS?

Proactol is a weight loss supplement. Serving size is equal to one capsule.

  • Chitosan (500mg): Derived from Aspergillus Niger Mycelium a type of black mould that is familiar to gardeners and vegetable producers, it is also a source of chitosan, a type of fibre is derived from the cell walls of plants. It is a natural sugar that may help prevent fat absorption, but the clinical research is very conflicting. Some of the clinical trials have not been of high quality and although chitosan may generate some weight loss, in many clinical trials effects were seen to be minimal. Source

Does Proactol XS Have Any Side Effects?

The clinical trials found that Chitosan derived from Aspergillus Niger Mycelium was reasonably safe for most people.

Potential side effects may include mild digestive issues such as;

  • Gas
  • Constipation
  • Stomach upset
  • Nausea

Not suitable for individuals under 18. Avoid if you are pregnant or breast feeding. Speak with your doctor first if you have an underlying medical condition or are taking prescription medication in case of interactions.

Are There Any Customer Reviews For Proactol XS?

There are no independent customer reviews for Proactol XS, because this supplement is on sale solely from the official Bauer Nutrition website.

There are a few customer testimonials on the website, but we cannot guarantee they are genuine or that any adverse comments have been filtered out.

Comments include,

Like nothing that’s on the market. Great to have before a meal as it stops you over eating

Worked wonders for me so far. Tried it for a month without changing anything else in my diet or doing any extra exercise and lost roughly 10 lbs which is amazing! Just re-ordered the 90 day supply since that seems like a great deal and just help me lose enough weight in the next 3 months.

There are six customer reviews in total and all are equally positive.

Does Proactol XS Offer a Money-Back Guarantee?

According to the advertising there is a 60 Day Guarantee.

The information reads,

If you are not completely with your purchase simply return it with 60 days for a full refund.

We would advise acting pretty fast if you want to return your item, because in the Terms and Conditions it states that you should contact customer services within 14 days.

We were concerned that customers would have to return their packages to Cyprus. However for UK customers, the return address is actually in Glasgow.

Where Can I Buy Proactol XS?

Proactol XS only seems to be available via the Bauer Nutrition website. It is available to worldwide customers including the USA, UK, Australia, Canada, the Euro zone, and Mexico.
