XLS Medical Max Strength Ingredients

XLS Medical Max Strength ingredients include:


Clavitanol is a patented organic plant-based complex; with the active component being IQP-VV-102 (Arabinose (600mg) and Grape Marc Extract (45mg)).

Other ingredients in the supplement include microcrystalline cellulose, HPMC, tri-calcium phosphate, and magnesium stearate.

Does XLS Medical Max Strength Work?

XLS Medical Max Strength contains Clavitanol, a patented ingredient supposedly helping block the activity of digestive enzymes, including lipase and amylase. It may help reduce the breakdown of sugar, carbohydrates, and fat. Since these nutrients are too large to be absorbed by the body, they are left undigested and pass naturally through the digestive system.

If you’re using XLS Medical Max Strength capsules, you’ll take two tablets before two of your daily meals. The company recommends not exceeding four XLS Medical Max Strength capsules per day.

Those using XLS Medical Max Strength sachets will take two sachets 30 minutes before two of your daily meals. Again, it’s recommended not to use more than four sachets per day.

XLS Medical Max Strength Lawsuits

In February of 2016, XLS Medical Max Strength was banned by the Advertising Standards Authority, according to Business Insider. The controversy started after a commercial for the pill aired.

The advertisement, which sparked more than 200 complaints, featured two healthy women talking about their upcoming holiday. One of the characters depicted communicated that she was miserable because she would never fit into her “holiday clothes,” and a friend offered her XLS Medical Max Strength.

Later in the video, the pair seem to be laughing and smiling on the beach. However, the already healthy and slim women were the same size after. The ASA claimed this promoted a poor body image and lack of confidence, and that the use of the products were not in a socially responsible way.

XLS-Nutrition Powder

A meal replacement shake available in flavors including chocolate, strawberry, and vanilla. It provides 28 grams of high-quality protein, B vitamins, and various nutrients to boost energy levels, control appetite, reduce calorie intake, and aid with weight loss.

XLS-Medical Fat Binder

It is a fat-binding supplement for weight management and weight loss. It binds up to 27% of the dietary fat you consume, so the body won’t absorb it. It also helps reduce appetite and may encourage up to 3 times more weight loss than diet and exercise alone.

XLS-Medical Hunger Buddy

A supplement helping fight food cravings and “snack attacks.” Aside from promoting satiety, this product enables you to cut your portion sizes, so you consume fewer calories each day. It helps you lose weight over time.

XLS-Medical Appetite Reducer

This is an appetite suppressant claiming to fill up 30-43% of your stomach, which helps you eat smaller portions and control hunger pangs. This product is mainly for dieters who have trouble controlling their appetite.

Look at other products helping with appetite control and weight reduction. Some even contain alternative fat and carbohydrate blocking ingredients such as Chitosan and White Kidney Bean Extract. This way, you can compare prices, customer reviews/results, and ingredient labels to determine the best choice for you and your weight loss goals/needs.

What Users Are Saying

“I tried for 4 months and lost about 3 lbs in all.”

“Absolutely worthless, don’t waste your money. Both me and my aunty tried it for at least a month and it didn’t boost our weight loss. We ate healthy and work out 4-5 times a week so it wasn’t because we ate unhealthy or being lazy. Please don’t waste your money on this product, it is too pricey and it does nothing.”

“I have taken these whenever I want to lose weight and find they really help, the downside is they make me constipated but if you eat vegetables regularly this does not happen. Very expensive but they help me.”

9 XLS Medical Max Strength Reviews

    Pat robinson (Verified Purchase)

    I am an extremely fit woman of 75…having run 15 marathons and 20 half marathons and other distances up to the age of 72. I still train (power walk, cycle, swim) for minimum of 1 hour EVERY DAY. I put on 10lbs when I stopped racing and have managed to lose 5lbs but thought I’d try this max strength tabs for 7 days. I HAVE NOT CHANGED MY HEALTHY EATING HABITS (I don’t have sugar and don’t drink and eat lots of fruit and veg and 3 slices of bread a day. MY WEIGHT REMAINS THE SAME AFTER TAKING FOR 1 WEEK …so total waste of money.

    Lesley (Verified Purchase)

    Have been taking the powder form of max strength as I hate taking tablets. Lost 5lb in 6 days so seems to be working along with a calorie controlled diet. Just wondered if anyone was having hot flushes as this seems to happen once I’ve taken a sachet then eaten

    • Annabel

      OMG! I’ve been psychologically hooked on this stuff for a year now and have spent a fortune. I am 46 and thought my hot flushes were the perimenopause. I am going to stop them and see if the flushes stop. My anxiety and moods have been incontrolable. It could be one or the other, or BOTH! It has kept my weight down but I have been sweating so much it is not a surprise.

  • Manish

    Not sold in my country-a friend puchased in Uk and I was super excited to lose weight n followed diet also- to my shock I bloated extremely had lots of stomach pain and at the end I gained almost 4 kilos! Disappointed esp for the price……

    • Montana (Editor)

      Hello Manish! We’re sorry to hear about the side effects you’ve experienced with XLS Medical Max Strength. If you haven’t already, we suggest discontinuing use. You might want to try another weight loss supplement that’s more affordable and is backed by clinical research; Dietspotlight Burn.
