XLS-Nutrition Meal Replacement Shake

Updated May 22, 2019.
Published Jul 9, 2018.

Advertised on TV, XLS-Medical is a very well known brand across the UK and Europe with products available from High Street stores, supermarkets, and online stores. XLS-Nutrition is manufactured in Germany and appears to have dropped the Medical part of the name for this particular supplement. XLS-Nutrition Meal Replacement Shake is, as you probably gathered by the name, a milkshake-type drink that you consume in place of your usual meal. This actually seems to be a decent product, but meal replacement shakes border on fad diet territory, as it is hard to stick to such a diet.


  • May help weight loss as described
  • Safe and unlikely to cause any side effects
  • Easily available to buy in the UK and across Europe


  • Some customers have complained about the flavour and consistency
  • Use incorrectly and you could put on weight
  • Could lead to yo-yo weight gain
XLS-Nutrition Meal Replacement Shake
XLS-Nutrition is a meal replacement shake which is available in a choice of three flavours and is high in protein and vitamins, yet only contains 250 calories per serving. It comes with a free weight loss plan to help you on your way.

So, is it worth a try? We take a look at XLS-Nutrition to find out more.

XLS-Nutrition Meal Replacement Shake Overview

What you need to know about XLS-Nutrition Meal Replacement Shake

XLS-Nutrition is a meal replacement shake that contains a blend of protein, vitamins, and minerals. The idea is that you use it to replace up to three of your meals a day and if you use as recommended you should lose weight, hopefully without feeling too hungry. Protein shakes can be effective for many people but it will depend upon your own habits, willpower, and lifestyle as to whether it will work for you. XLS-Nutrition is easily available to buy in the UK and across Europe and is a well-known brand, so you have the assurance that it is safe and tested. XLS-Nutrition is manufactured in Germany.

What are the side effects of XLS-Nutrition Meal Replacement Shake?

Potential side effects may include constipation, bloating, nausea, thirst, cramps, fatigue, headache, stomach cramps, and increased bowel movements.

How much does XLS-Nutrition Meal Replacement Shake cost?

Each tub of XLS-Nutrition contains 10 servings so if you use it to replace three meals a day, it will obviously be a lot more costly than if you just use once a day.

Prices vary depending on where you buy and there is some variation to prices for the flavours. It costs £15.99 per tub (10 servings) on Amazon UK for Vanilla flavour. Chocolate or strawberry flavour costs £16.10.

Use three times a day for a week as advised adds up to 21 servings so you will need to buy 3 tubs, making the cost around £48.00!

You can also pay £18.10 for vanilla flavour if you want the Shaker. Many customers have said this is very useful. You will need to check the product details when you buy to see whether or not the shaker is included.

Elsewhere, prices are comparable and you can shop around to make additional savings.

XLS-Nutrition Meal Replacement Shake Key Features

XLS-Medical Nutrition is a meal replacement shake and the idea is that you can replace up to three meals a day without missing out on vital nutrients such as vitamins and protein, yet reduce your calorie intake to less than 1000 a day. You don’t have to do this. You can just use XLS-Nutrition once a day in place of a meal; it all depends on how much weight you want to lose and how you feel about replacing a normal meal with what looks and taste like a milkshake.

XLS-Nutrition Meal Replacement Shake Key Points

  • Three flavours: vanilla, strawberry, or chocolate
  • You can buy an additional Shaker to make mixing easier
  • Contains 250 calories per serving, including milk
  • Contains 15g of sugar per serving

There are three flavours; strawberry, vanilla, and chocolate, and you can also buy a shaker for easy mixing. There is also a free weight loss plan, although this is not very informative and simply advises that you replace 3 meals a day with the Shake for the first week, and replace 2 meals a day with the Shake on the second week. The continuation weight loss plan is much the same. However, there is a list of healthy recipes on the XLS website that you can access and use in combination with the Shakes.

Meal replacement shakes can be very effective for some people but it is important to remember that they are designed to replace a whole meal. If you drink the shake and then continue to eat, you will put on weight because there is nothing “slimming” about the shake. As a meal replacement, 250 calories is good. As an additional drink, it is extremely fattening! Oddly enough, the vanilla flavour is the only one where it recommends you add 1/2 teaspoon of oil along with 200ml semi-skimmed milk.

How to Take XLS-Nutrition Meal Replacement Shake

  • Shake the XLS-Nutrition tin before use
  • Pour 200ml semi skimmed milk (1.5 % fat) into your XLS-Nutrition shaker
  • Add 4 heaped measuring spoons (40g) to your shaker
  • Finally, add 1/2 teaspoon (1.5g) unsaturated vegetable oil (e.g. sunflower, safflower, rapeseed or olive oil)
  • Tightly close the lid and shake it vigorously
  • If XLS-Nutrition is prepared with water instead of milk, a prepared portion contains: Vanilla Shake: 592 kJ (140 kcal)
  • The preparation with water is not a replacement for a complete meal

The ingredients profile of XLS-Nutrition looks good. The protein is provided by soy protein isolate and lactose-reduced whey protein concentrate, both rich in amino acids and nutrients. There is also an extensive vitamin and mineral profile. Not so good is the addition of sugar at 15g per serving. Take a look at the ingredients profile to find out more.

XLS-Nutrition Meal Replacement Shake Concerns:

  • You need to add the powder to milk in order to make a complete meal replacement but will customers realise?
  • Could cause rapid weight loss if used correctly which could lead to yo-yo weight gain
  • Use incorrectly and you probably will put on weight
  • Very little fibre so may cause constipation

XLS-Medical is a very well known weight loss brand across the UK and Europe with supplements on sale from just about everywhere including ASDA, Tesco, Superdrug, Holland & Barrett, and Amazon. We have covered many XLS supplements before, including XLS-Medical Carb BlockerXLS-Medical Appetite Reducer, XLS-Medical Direct, and XLS-Medical Max Strength.

What does XLS-Nutrition Meal Replacement Shake claim to do?

According to the product information, XLS-Nutrition is a “healthy and simple weight loss shake”

The key features are as follows:

  • Nutritionally complete
  • 31g High quality protein for optimal health
  • B-Vitamins for energy release
  • Scientifically Proven

The information explains further,

As part of a calorie reduced diet, XLS-Nutrition replaces an entire meal and has fewer than 250 calories while providing you with all your essential vitamins and minerals. Vitamin B5 and B12 promote normal energy metabolism, and vitamin B6 promotes normal protein and glycogen metabolism. Ultimately maintaining your energy requirements and helping you reach your weight loss goals whilst utilising your fat reserves from day one.

The proteins are explained too,

The complete proteins in XLS-Nutrition are rich in essential amino acids which are well used by your body and have been specially selected for their high biological value. As a result, these proteins help maintain your muscles while our scientifically proven formulation helps you lose weight.

Does XLS-Nutrition Meal Replacement Shake work?

If you use XLS-Nutrition to replace meals, you will lose weight. The first week of the diet plan advises that you replace ALL three meals a day with the Shakes so if you can stick to this, your calorie intake will be greatly reduced to less than 1000 calories a day, so you cannot really fail.

The fact that the Shakes contain protein with added vitamins should help you maintain good health and energy levels without too much hunger. Some people will manage to stick at this and then gradually reintroduce ordinary food over the next few weeks. Do this and it may work.

The problem is that replacing meals with Shakes can be extremely hard going, and it does rely on a lot of willpower to keep to this liquid lunch in place of food. In addition, it is a type of fad diet so in common with all fad diets, it may help you lose weight quickly, only to pile it back on once you have finished.

We question the statement that this “scientifically proven formulation helps you lose weight”. What will help you lose weight is the way you use it because there is nothing at all slimming about the Shakes. Use incorrectly and you may find you put weight on and not lose it.

The best way to lose weight and to keep it off is to change your eating habits to something that you can live with on a permanent basis. That way you do not need any special willpower and although weight loss may be slower, it is more likely to be permanent. That said, XLS-Nutrition will probably work if you can stick to it and it does provide an easy structure for you to follow without the need for too much preparation or thought about calorie counting. In addition, you may find it useful to replace a meal with a shake when you are time-pressed or faced with more unhealthy options.

XLS-Nutrition Meal Replacement Shake Ingredients

Serving size is equal to 4 scoops of powder added to low-fat milk.

The nutritional breakdown is as follows:

  • Calories: 247
  • Fat: 5.4g (2.8g saturated fat)
  • Carbohydrates: 18.1g (sugar 15.2g)
  • Fibre: 0.9g
  • Protein: 30.8g
  • Salt: 1g

The protein is provided by:

  • Soy protein isolate: Derived from Soybean flour, Soy protein isolate is a highly refined form of protein which has had most of its fats and carbs removed and it is a complete protein because it contains all of the essential amino acids needed for health. Some people have health concerns about taking soy protein isolate long-term (over 6 months) because of a perceived hormonal effect. It contains natural chemicals called isoflavones which mimic oestrogen in the body. Source
  • Lactose reduced whey protein concentrate (milk): This is the most common form of whey protein and the cheapest. Whey is a by-product of cheese production and is often used in bodybuilding and replacement meal supplements because it is a cheap and reasonably effective source of protein but it does contain fat.

The Shake has an extensive mineral and vitamin profile derived from the following ingredients:

  • Honey (15%), maltodextrin, flavour, dipotassium phosphate, magnesium hydroxide, anti-caking agent (silicon dioxide), calcium chloride, rapeseed oil, vitamin C, tricalcium phosphate, zinc gluconate, vitamin E, ferric phosphate, nicotinamide, manganese gluconate, antioxidant (DL-alpha-tocopherol), soy oil, vitamin B5, colour (beta-carotene), vitamin B6, vitamin B1, vitamin A, cupric gluconate, vitamin K, sodium selenite, folic acid, vitamin B2, potassium iodide, vitamin D.

XLS-Nutrition Meal Replacement Shake Customer Feedback

Yes, there are plenty of reviews for XLS-Nutrition available. We took a look at Amazon UK to find out what people are saying about this supplement.

There are some weight loss success stories.

I started using this on 5th June and was 104.8 Kg – using it twice a day for breakfast and evening meal replacement. For lunch I’m having soup and salad so I think it’s a fairly healthy diet. Yesterday 16 June I weighed 99.4 Kg – very pleased to lose 5.4 Kg that’s nearly 10 pounds in old money!

I’ve got both the vanilla and the chocolate – not tried the strawberry yet. I prefer the vanilla – tastes good with semi-skimmed milk. There are cheaper shakes but this seems to be working for me.

This works! Lost 9lb in 2 weeks However it tastes a bit floury and for me it was better half milk half water. The results were good hence rating as it does what it says but I think it is a bit pricey unless on offer.

Some reviewers felt it was OK but nothing special, such as this customer,

Tastes ok but quite hard to mix properly; have to proper shake it up to make it dissolve. Does seem to work, but I did feel hungry a bit as not used to the portions I suppose. Did lose weight. The shaker is ok but you can use any old gym/bike water bottle really. Main gripe is the price per serving.

One woman could not actually drink it!

This product is absolutely gross. Even if you follow the mixing instructions, the drink is powdery and sickening. I can’t even tell of it helps with weight loss or not because it’s vile to drink.

Other customers have enjoyed the flavour,

This tasted really nice and had a much “fresher” taste than other drinks like Slimfast. At the end of the day it’s down to personal willpower I guess, but this did help me lower my daily calorie intake. Bit of a hassle washing the container, but apart from that was very convenient. PS. you can take this with either milk or water.

In the UK it is on sale from major supermarkets such as Asda and Tesco, as well as pharmacies such as Boots and Superdrug. You can also buy from these retailers’ online outlets and Amazon. Across Europe, it is equally easily available from similar outlets.

American customers can find XLS-Nutrition on sale from Amazon USA.

Watchdog Verdict

XLS-Nutrition is a good quality shake supplement. We like that the calorie count of 250 per serving includes the milk content, and we feel that you could lose a lot of weight by using it especially if you replace three meals a day over a week. There is some good customer feedback and it could be a good way to make a very effective start to your weight loss plan.

However, meal replacement shakes do not work for everyone. A lot will depend upon your willpower and whether or not you enjoy the flavours. A big problem with using a program of meal replacement shakes is that it is venturing into fad diet territory where you lose a lot of weight quickly only to pile it all back on once the regime is over. If you do continue to eat on top of taking the shakes, it will add to weight gain.

We quite like XLS-Nutrition and feel that for some people it just may work. However, in our opinion losing weight by meal replacement shakes is not as easy as it sounds and for some people requires far too much willpower for it to be successful.

Overall, we do not recommend XLS-Nutrition to the Watchdog readers.

1 comment on 'XLS-Nutrition Meal Replacement Shake'

  1. I have used XLS meal replacement shakes and lost loads of weight. I started with 3 shakes a day for a couple of weeks and then I started an exercise routine so changed to 2 shakes a day with a healthy meal or meal type soup, I didn’t have enough energy to exercise on 3 shakes a day. It does take a lot of will power & effort but I’ve seen quick results, a big beer belly to a flat stomach in a couple of hard months, I’m not talking abs but no bulge.

    Regarding yo yo this should only happen if I’m stupid enough to go back to my old lifestyle. Losing the weight has inspired me to keep it off. I’m still using the shakes once or twice a day with a normal meal and am fitter so can exercise more which I’m loving.

    I’ve had none of the side effects listed and I use a small blender to mix the shake so it’s not powdery at all and I actually enjoy them.

    Would thoroughly recommend this product but it’s not fairy dust you have to follow it properly and watch your diet and exercise. What this has given me is quick results which has boosted my motivation to succeed and continue.

    For ref: I’m 60 and have had 2 half knee replacements so can so have to monitor my style of exercise.
