XLS Medical Max Strength is available in the USA, UK and mainland Europe. It is one of the most recognizable weight loss products on the market. A fat blocker by definition, XLS has positives and negatives – find out what they are in this review

XL-S Medical Max Strength is a weight management tablet produced in Europe by Omega Pharma.
The company produces a vast amount of products under several different brand names. The XLS Medical range of products are all designed to provide weight loss.
As is usually the case with XLS Medical products, Max Strength is designed to work as a blocking mechanism.
The company already markets a fat blocker and a carb blocker, so the fact that they have now developed a product that is designed to block carbs, fats, and sugars could be seen as a natural progression.
The latest product to hit the shelves is XLS Medical Ultra 5 with a new ingredient called Okranol.

How the Formulation Works
Fats, carbs, and sugars all share a common quality—they are calorie providers.
Calories are the fuel that is necessary to keep the body functioning, but when the body gets more calories than it needs it stores them away and gets fat.
XLS Medical Max Strength is designed to limit the amount of calories fats, carbs, and sugars provide by blocking their assimilation.
XLS Medical are responsible for serval other slimming products including XLS Medical Carb Blocker, Calorie Reducer as well as arguably the best selling of the range
Active Ingredients
The tablets only contain one active ingredient.
It’s called Clavitanol and one clinical trial, conducted in 2013, suggests its use can improve dieting success by 33% (compared to the placebo group).
Once ingested Clavitanol gets to work inside the stomach and inhibits the function of alpha amylase, alpha glucosidase and lipase.
These are the digestive enzymes that are responsible for the smooth digestion of fats, carbohydrates and sugars.
By impeding the function of these important enzymes, Clavitanol causes the aforementioned nutrients to pass through the digestive system more or less untouched carrying their calorie content with them.
Because the calories are not released they are lost and the body is then more likely to be starved of energy and forced to commence fat burning to compensate for the deficiency.

How to use XLS Medical Max Strength
XLS Medical Max Strength should always be taken with water.
Two tablets are required twice per day and should be consumed before the two main meals of the day.
The manufacturers also recommend drinking plenty of water throughout the day.
XLS Medical Max Strength Customer Testimonials
Although there are a few extremely positive reviews, the majority of past customers appear to either be unsure about how well the product has worked for them or slam it for not working at all.
“I can’t leave a positive review. I did not notice any weight loss while I was taking the tablets even though I followed the advice about diet and exercise.”
DD, London UK
“My wife took these for a month. She works out regularly at the gym and eats a healthy diet, but needed a little extra help to shift some belly fat. These tablets turned out to be a complete waste of time and money.”
Alan G, Detroit USA
XLS Medical Max Strength Side Effects?
The tablets are unsuitable for pregnant or breastfeeding mothers and should also be avoided by anyone who is allergic to corn, grapes, or any product that contains their derivatives.
Use of the tablets could also present issue for diabetics and some adjustment of medication may be necessary to prevent hypoglycaemic attacks.
However, overall the formulation should be tolerated well by the majority of users, with the most likely side effect being intestinal wind, caused by the presence of partially digested carbohydrates.
XLS Medical says such a reaction is only likely to be a problem during the first few days of supplementation, but a number of customer reviews indicate otherwise.
Anyone who is taking medication or has existing health issues should always seek medical advice before using any form of weight management supplement.

FAQ’s
The manufacturer admits XLS Medical Max Strength may cause gas, but assures potential customers the problem will only last a few days. Most products that offer a carb blocking action present this kind of risk. It’s how the body responds to the presence of undigested carbohydrate in the gut.
The fat that is blocked passes through the intestines in an unprocessed state. Eventually, it leaves the body as part of the stool. However, its presence is likely to make the stool softer and greasier than normal. It’s also possible that small amounts of fat may exude from the rectum and cause greasy spots to appear on the underwear.
InQpharm state it’s 33% more powerful than the original product. However, the product offers a combination of fat blocking and carb blocking. It seems probable people who have a specific need for fat blocking would find the original product may be most suitable for their needs.
It’s made by InQpharm Group. XLS Medical is just a brand name the company uses for marketing certain products. The company is based in Kuala Lumpur, Malaysia, and operates on an international level. It maintains offices in the USA, United Kingdom, France, Germany, and many other countries all over the world.
Products that block fat and/or carbohydrate absorption assist weight loss by providing calorie control. A gram of fat contains 9 calories. A gram of carbohydrate has 4. When you eat food that provides fat and carbohydrate, after the nutrients are processed, the energy (measured in calories) is absorbed and used for energy. If the body does not need the energy it stores it as fat. Nutrient blocking supplements prevent some of the nutrients from being processed. This is how they control calorie intake.
Although exercise may not be strictly necessary, upping levels of physical activity always aids the weight loss process. A low-calorie diet is more important. All weight loss supplements only work when used alongside this type of diet. They cannot replace it.
If you are serious about losing weight, there should be no cheat days. Using this type of product while eating large quantities of fat or carbohydrate is not healthy and may upset the stomach. Furthermore, eating too much fat with any brand of fat blocker can result in explosive diarrhea.
No. XLS Medical Max Strength is only available in tablet format and as a powder. The powder is packed in individual one-shot sachets that are poured into the mouth and can be taken without water.
Both contain the same ingredients, so they should work in a similar manner. However, the sachets will be a much better option for anyone who finds it difficult or unpleasant to swallow pills.
It blocks both nutrients by suppressing the abilities of the digestive enzymes that break them down into particles small enough to be absorbed. There are many digestive enzymes involved in digestion. The enzyme lipase is responsible for processing dietary fat. Amylase processes carbohydrate. XLS Medical Max Strength works by inhibiting both enzymes. The proteases and peptidases that breakdown protein are not affected, so protein is digested as normal.
It only contains one active ingredient. It’s a proprietary blend called Clavitanol. This, in turn, may contain other ingredients. Such is the case with proprietary blends. The problem is, InQpharm is very cagey about revealing the true nature of the ingredient. Apparently, it’s a plant-based phenol. Nothing else is known. This is a very poor state of affairs because there is no way of knowing what plant it has been taken from.
You take two tablets or one sachet two times each day. The best time to use the product is 30 minutes before the two largest meals of the day.
Although some degree of appetite suppression may be possible, this is not an area in which the product is likely to excel. If you are trying to lose weight and find it hard to get to grips with your hunger, there are other products that will help you more.
Only in an indirect fashion. When used alongside a low-calorie diet, the nutrient blocking action of the product will further lower the calorie intake. The extra shortfall of calories will cause a greater need for fat burning. Genuine fat burning supplements attack the problem of weight loss from the other side. Instead of reducing calorie intake they speed up metabolism to increase calorie burn.
No. XLS Medical products never have a money back guarantee.
No. Like all the XLS Medical products, it’s possible to buy Max Strength in most good pharmacies. You can also find it on the shelves of many supermarkets chains.
InQpharm never offers any special deals. It’s possible that certain third-party retailers may do so but any savings involved are likely to be quite small. The retailers’ ability to make any kind of price reduction will be limited by their own purchase costs, which are likely to stay pretty much the same.
