Evolution Slimming Glucomannan Plus is a high-fiber supplement that’s primarily aimed at people who need something to control their hunger and make it easier to lose weight.

Like most similar supplements, it comes in the form of a capsule. However, in somewhat of a break from tradition, Glucomannan Plus is sold in boxes instead of bottles. Each box contains four blister pack cards, there are 15 capsules per card, and 60 capsules per box.

The other difference is, each box only contains a 10-day supply of capsules. Most supplements come in a 30-day supply. However, this is not a big issue because the monthly cost of using Glucomannan Plus is still less than that of using most alternative products.

This review explains how Evolution Slimming Glucomannan Plus works, evaluates the potential of the ingredients, and provides other information you may need to help you decide it’s the right product for you. Additionally, it provides price information and tips on getting the best possible deal.


A Look at the Company Behind Glucomannan Plus

Glucomannan Plus is manufactured in the UK by Evolution Slimming. The company is based in Kent and operates worldwide.

Evolution Slimming Trustpilot RatingEvolution Slimming is a respected manufacturer that’s been active in the supplement industry since 2007 and provides a wide range of products that aim to help people lose weight, get fitter, and enjoy optimum health. The company also offers a range of skin and hair care products.

One of the good things about Evolution Slimming is it doesn’t use its brand reputation as an excuse to inflate prices. Nor does it cut corners when it comes to quality. It aims, instead, to provide good value for money.

At the time of this review (June 2020), the Trustpilot website was showing 1,976 reviews. Seventy-two percent of the customer ratings were “excellent” and a further 16% of customers were saying Evolution Slimming is “Great”.

That’s a lot of positive feedback. It’s rare to find a company that’s such a big hit with consumers. Especially in the supplement industry.



Glucomannan Plus: The Promised Benefits

There is not a lot of hype with this product. Evolution Slimming simply makes a brief statement about who it aims to help.

It’s for people who:

  • Need help reducing or managing their weight
  • Are troubled by hunger in between meals
  • Suffer from diabetes and are looking for a safe & natural way to regulate blood sugar levels
  • Have a problem with constipation or soft stools

Although the following things are more selling points than benefits, the formulation is also:

  • Vegan and vegetarian-friendly
  • Free from dairy and caffeine

Many diet pills are loaded with caffeine and/or other stimulants. A lot of people don’t want that. If you are looking for a stimulant-free weight-loss experience, Glucomannan Plus is a product you may want to consider.


How Does Glucomannan Plus Work?

Glucomannan Plus Appetite Suppressing CapsulesEvolution Slimming Glucomannan Plus contains a water-soluble fiber called glucomannan. When you swallow glucomannan with water, the fiber expands and creates a feeling of satiety that reduces the desire for food.

Glucomannan is one of the best natural appetite suppressants in the world and there’s plenty of research that proves that it works.

Research also proves glucomannan’s ability to reduce cholesterol. That’s not likely to be overly interesting to the average person seeking information at DietPillNija.com. However, it’s important that I mention it because lowering cholesterol is one of the claims Evolution Slimming is making for this product.

There are plenty of weight management products that contain glucomannan and many of them provide the same dose. This one is called Glucomannan Plus because it provides additional benefits as well.

In addition to glucomannan, the formulation also provides green tea. It’s a proven fat burner that may allow this product to do a little more for dieters than a standard glucomannan product can.

The formulation also contains chromium, which is sometimes used for managing diabetes. Chromium is also an incredibly popular diet pill ingredient because it may help reduce carb cravings, along with sudden desires for sugary treats.

Make no mistakes about it, though. If you choose this product, you need to be looking at its ability to control hunger. Anything else is just a bonus. However, it’s a bonus you won’t get if you go with a basic glucomannan product.

Things to Bear in Mind

Like other weight management products, Evolution Slimming Glucomannan Plus is a supplement. It’s important to understand what a supplement is and never to see any form of supplement as a magic pill.

The word “supplement” refers to something you get or use in addition to something else. For instance, Some people work two jobs to “supplement” their income.

Diet pills and other weight loss supplements, supplement the efforts you are already making by controlling your diet.

In this case, it’s important not to see Evolution Slimming Glucomannan Plus as a product that provides an excuse not to try and eat healthy foods. The pills will work best if you use them alongside a healthy diet that contains nutritious foods that are low in fat and sugar.


Glucomannan Plus: List of Ingredients

Each (2-capsule) dose provides:

  • Glucomannan/Konjac Powder    (1000 mg)
  • Green Tea Extract                             (100 mg)
  • Chromium                                              (12 μg)


How Good Is Glucomannan Plus?

This is the part of the review where we take a closer look at the abilities of the ingredients and see if they can enable Glucomannan Plus to do the things it’s meant to do.



Glucomannan is the name supplement manufacturers often use for the ingredient you get when you mill the roots of a plant called konjac and reduce them to powder.

Glucomannan is super-absorbent. It can absorb up to 50 times its own weight in water. When this happens, the glucomannan fibers expand. The resulting compound is a jelly-like mass. When this mass forms in the stomach, it makes it feel full.

Many studies prove glucomannan is an appetite suppressant that works. The European Food Safety Authority (EFSA) has evaluated all the claims made for glucomannan. It states a dose of 1 gram, taken three times per day, with sufficient water can suppress appetite and help people to lose weight.

Each dose of Glucomannan Plus provides the right amount of glucomannan and Evolution Slimming provides instructions that ensure people use it correctly.

The EFSA has also evaluated the data from studies exploring glucomannan’s ability to reduce cholesterol. It agrees it can do this too so all the glucomannan-related claims for this product pan out. It should do what it’s meant to do.

If you want more in-depth information about glucomannan and its ability to help you to lose weight, I have an article about it on a different page of this site. Needless to say, the article provides links to the EFSA’s evaluation.

Green Tea Extract

Has anyone ever told you green tea is a healthy beverage to drink? If so, they were telling you straight. It’s one of the healthiest beverages in the world. The antioxidants it provides (green tea catechins) reduce oxidative stress, enhance the immune system, purge the body of free radical toxins, and help prevent disease.

Green tea is also one of the most popular diet pill ingredients in the world. There’s a good reason for this. There’s a mountain of evidence that shows green tea is a fat burner that works.

Green tea supports fat loss in two ways. Firstly, it accelerates metabolism. When your metabolism is faster you burn more calories. Even when you are asleep.

Burning more calories is good. It can help you to lose weight faster, but you’ll only see the benefit if you are following a low-calorie diet that’s already helping you to lose weight.

Don’t think of green tea as a magical weight-loss provider. Accept it for what it is—something that can aid your existing efforts and help you to lose weight faster.

Research shows green tea also increases thermogenesis. By doing this, it causes you to lose extra energy (measured in calories) into the air around you, in the form of heat.

Some research suggests the fat-burning benefits of green tea can last for up to 24 hours so it’s a good ingredient to have. Here’s a link to a study you may find interesting: https://academic.oup.com/ajcn/article/70/6/1040/4729179



Chromium is a mineral. Do you need it in a supplement? Possibly not because you can get it from broccoli and many other foods. However, it’s still a very popular diet pill inclusion.

So, why do so many diet pills contain chromium? It’s because of the relationship it has with blood sugar and insulin.

This relationship is not fully understood but there is limited evidence to suggest supplementing with chromium may lower glucose intolerance sufficiently to be helpful to people suffering from Type 2 diabetes. (https://pubmed.ncbi.nlm.nih.gov/15296075/)

Chromium is added to diet pills because its presence may help prevent the battle between blood sugar and insulin that sometimes occurs after a meal. If you have ever eaten a meal and then been hit by a craving for something sweet or high in carbs, you will have experienced the result of this battle.

If your meal (or choice of food) causes your blood sugar level to rise too fast, your body will respond by instructing your pancreas gland to pump out extra insulin.

Insulin brings blood sugar levels down. However, if it brings blood sugar levels to low (a blood sugar crash), your body will try to restore normality by making you crave foods that are high in sugar and carbs.


How to Use Evolution Slimming Glucomannan Plus

When you are using Glucomannan Plus to support weight-loss, the dose is two capsules, three times per day. You take the doses 15-30 minutes before meals with a large glass of water.

If you are using the product to lower cholesterol, the dose is eight capsules per day.
Evolution Slimming also provides guidelines for using Glucomannan Plus to treat constipation and help with Type 2 diabetes.

Although the guidelines for diabetics seem very level-headed, it would be unwise to use this product to manage diabetes without getting a doctor’s approval first.

Words of Wisdom:

If you are pregnant or nursing a child, please don’t take any kind of supplement without getting clearance from your doctor first.

If you have an existing medical condition of any kind at all, it would also be unwise to use supplements without checking with your doctor first.

Certain supplement ingredients can present interaction issues when combined with medication. It doesn’t matter if the medication has been prescribed by a doctor, a dentist, or another medical professional. If you are taking medication, don’t use it with supplements without asking a doctor first.

Does Glucomannan Plus Have Honorable Customer Reviews?

It’s hard to find independent sources of customer feedback. At the time of this review, the Glucomannan Plus sales page at Amazon only had one comment and it was short and sweet:

Glucomannan Plus Customer Review (From Amazon)


I have to see the Evolution Slimming website as a biased source, but it does provide plenty of reviews from customers who are saying the product works well.

Here’s a couple of examples:

Glucomannan Plus Customer Reviews (From the Evolution Slimming Website)


Does Glucomannan Plus Cause Side Effects?

Side effects are unlikely but Some people find glucomannan makes them feel bloated and/or causes wind or diarrhea but negative issues are rare.

Green tea is unlikely to cause side effects either. Nor is chromium but, due to the way it interacts with blood sugar and insulin, if you are diabetic it makes a lot of sense to consult a doctor before using any product that lists chromium amount the ingredients.


The Best Place to Buy Glucomannan Plus

If you want to buy Glucomannan Plus online, the best option is to get it via the Evolution Slimming website. Buying direct will enable you to be certain you are getting the genuine product.

In the UK and certain other countries, it’s also possible to buy the product via Amazon. However, to avoid counterfeit products you need to certain you are buying Glucomannan Plus from Evolution Slimming’s official Amazon Store.*

If you buy via Amazon, the price per box is the same as when you buy directly from the manufacturer’s site so, for single-box purchases, it won’t make a lot of difference which option you choose.

However, a box of Glucomannan Plus contains 60 capsules. That’s only enough to provide 10 days of appetite control.

Bearing this in mind, it may be best to buy three boxes. When you buy Glucomannan Plus from Amazon, the cost per box remains the same (information correct at the time of this review). There are no bulk-buy discounts or incentives.

Buying directly from the Evolution Slimming website allows you to get a modest discount when you purchase more than one box. That’s one of the reasons, I think buying direct is the best way to go. The other reason is, when you buy direct (from any company) it allows you to remove the middle-man and deal one-on-one with the company if any queries arise.

At the time of this review, the Glucomannan Plus prices, for single and multiple box purchases via the Evolution Slimming website, looked like this:

  • 10-Day Supply (60 Capsules):   £9.99 / $12 / €11
  • 20-Day Supply (120 Capsules): £17.99 / $22 / €20
  • 30-Day Supply (180 Capsules): £24.99 / $31 / €28

The savings are not dramatic, but they are certainly okay and it’s occasionally possible to get an even better deal if there’s a promotion. Evolution Slimming doesn’t run many promotions but you’ll know if it is because a pop-up will appear and offer a discount.

Evolution Slimming Promotion

If there is a promotion, see it as a bonus and grab a bargain if you can. The next time you visit the site, the option may not be there.


After the Sale (What Happens Next?)

Customer Service

Evolution Slimming offers an excellent level of customer service. Site visitors can contact the customer services team via Live Chat. The site also provides a UK 0800 freephone number you can use between 9 am and 5 pm (UK time).

The Evolution Slimming website also provides an alternative number for international visitors. You can also get in touch with the company via Facebook Messenger or by using the online contact form.

Guarantee and Product Returns

Unfortunately, Evolution Slimming doesn’t offer a money-back guarantee. It’s a pity, but that’s the way it is.

However, the amount of glucomannan Evolution Slimming’s product provides has been proven effective in many clinical trials, as has the dose and dosing schedule. The EFSA states you need to take 1 gram, three times per day, before meals, and that’s what Evolution Slimming is telling its customers to do.

Glucomannan Plus also contains green tea, which is a proven fat-burner. With a product as good as this, the lack of a guarantee should not be an issue. If you are following an energy-restricted diet it will help you to do what you need to do.


Glucomannan Plus – Diet Pill Ninja Review Conclusion

The Diet Pill Ninja: Honorable Diet Pill ReviewsThis is a good product. It’s also one that’s reasonably priced and it comes from a very credible manufacturer.

I am not qualified to comment on its abilities in other areas, but Glucomannan Plus is a great option for anyone who needs help getting their appetite under control.

The presence of chromium in the formulation should offer additional help by reducing the likelihood of post-eating hunger urges but, if you are planning your meals correctly, such urges are unlikely to be an issue.

The formulation also contains green tea. The dose is not particularly high but it may be enough to provide a slight increase in metabolism and provide additional health benefits as well.

However, a product like this one is best suited to people who are primarily interested in hunger control. If that’s what you need, this is a good option for you. If you are primarily looking for a fat burner, you may be better off going with something like Phen24 instead.

Nevertheless, if you want a powerful natural appetite suppressant that offers a few extra whistles and bells Glucomannan Plus is and excellent choice. Click here to get up-to-date price details from the manufacturer’s site.


Some FAQs

Is Glucomannan Plus suitable for vegetarians and vegans?

Yes. Neither the capsule contents nor the casings contain any gelatin or other animal extracts. If you are vegan or vegetarian, this is a diet pill that you will be able to use.


Do I need to use Glucomannan Plus with diet and exercise?

You will need to use the glucomannan alongside an energy-restricted diet. The main thing the product will do is make your diet easier by controlling hunger.

If you exercise it will help you to burn extra calories and lose weight faster. It will also help make you fitter and improve your overall health. However, if you are unable to exercise due to mobility issues or health problems, you will still be able to lose weight by dieting and using the pills to control your hunger.


Is it safe to use Glucomannan Plus during pregnancy?

It would be unwise to this or any other supplement while pregnant without a doctor’s approval. Equal caution will be necessary if you are breastfeeding a child.
