Slim Fizz Facts

  • Each pack contains 30 tablets. 10 days supply.
  • £19.95 per pack.
  • On sale from British company Proto Col.

Slim Fizz is an orange flavoured appetite suppressant drink that comes from British company Proto Col. If you don’t like taking pills but still want the support of a supplement, it offers an easy solution because you just add a tablet to water and drink in the same way as an Alka Seltzer or soluble aspririn.

Slim Fizz contains just one active ingredient; Glucomannan a water-soluble substance that is classified as a dietary fibre. This natural sugar is derived from the root of the Konjac plant a type of Japanese yam that is becoming popular as a weight loss ingredient.

Glucomannan is an indigestible fibre that stays in the stomach for a long time. It is in powder form that once added to water, forms into a gel like consistency giving you the sensation of feeling full. It helps maintain blood sugar levels too and may help reduce cholesterol.

Glucomannan has been reviewed by the European Food Standards Agency (EFSA) and the scientific opinion is that when taken regularly and in sufficient quantities, it may be effective for weight loss.

How to Take Slim Fizz

Dissolve 1 (one) tablet in a large glass of water (at least 200ml) and drink straightaway. Take 3 (three) times a day at least 30 (thirty) minutes before meals.

Slim Fizz comes from British company Proto Col. The company was founded in 2003 and is based in Bradford on Avon in Wiltshire. Proto Col specialise in skin care products such as collagen capsules, creams and moisturisers, as well as a range of cosmetics made from natural minerals.

There is also a nutrition range, which includes sports and weight loss supplements. We covered a weight loss supplement called Proto Col Thermo Lite in a previous review and although we felt that it had some good points, we did not add it to our approved list.

Overall Proto Col gives the impression of being a well-established and reputable company. There is full transparency regarding contact details and there is a designated sales and customer service phone line.

Proto Col is not associated with any scam issues around billing and payment.

Slim Fizz Concerns:

  • There is a choking risk associated with Glucomannan. You must ensure you dissolve the tablets in at least 200ml of water.
  • Could be a waste of money. Not all customers are satisfied and clinical evidence is based on consuming Glucomannan over months rather than weeks.
  • Expensive. Will cost you nearly £60.00 for just one month’s supply

What Does Slim Fizz Claim To Do?

According to the advertising, there are six key points about Slim Fizz:

  • Only 6 calories per serving.
  • Helps control hunger cravings.
  • Helps you lose weight.
  • Helps reduce cholesterol.
  • 10 day supply – includes 30 tablets.
  • FREE – Challenge Diet Plan included.

The way that it works is explained:

Once dissolved in water, Slim-Fizz forms a high-viscosity gel that expands in your stomach to help simulate the feeling of fullness. The gel forms what can be described as a temporary gastric band within the stomach and intestine track.

There are no details about the Challenge Diet Plan but it comes in the packaging with each box. According to Proto Col, it will help you:

Kick start your healthy living regime and achieve quick weight loss.

The tablets are gluten free, dairy free and are suitable for vegetarians.

So What Is Slim Fizz and What Are The Ingredients?

Slim Fizz is an effervescent food supplement that you add to at least 200ml of water in order to create an orange flavoured weight loss drink.

Each tablet is equal to one serving.

  • Glucomannan (1.58g): This indigestible fibre is derived from the Konjac root a natural plant which grows in Asia, is well known for its effect upon appetite. Because the stomach cannot digest Glucomannan, it stays in the gut for a long time and creates a feeling of fullness thus leading to the appetite suppressant effect. In addition, Glucomannan is known to reduce cholesterol levels and may be effective at maintaining blood sugar levels.
    Glucomann has been studied by the European Food Safety Agency (EFSA) to find if the weight management claims are true. The EFSA panel advised that in order to benefit from this ingredient “at least 3 g of Glucomannan should be consumed daily in three doses of at least 1 g each, together with 1-2 glasses of water before meals, in the context of a calorie-restricted diet.”
    In addition, “A claim on Glucomannan and maintenance of normal blood cholesterol concentrations has already been assessed with a favourable outcome.”

Slim Fizz also contains added sugars and salts. These are to provide the sweet orange flavouring and the fizzy effect.

  • Energy 24kj (6 kcal)
  • Carbohydrate (500mg) of which sugars make up 400mg.
  • Salt (233mg)

So What Does All This Mean?

With just one active ingredient and only 6 calories contained in each serving, Slim Fizz is a very straightforward looking supplement. The quantities of Glucomannan contained in each tablet are in line with EFSA findings and you may find that this orange flavoured drink may help reduce your hunger pangs and prevent low blood sugar spikes. As a result, this may help keep you on track on your weight loss diet.

If this is something you struggle with, you may find that Slim Fizz provides some support.

There have been issues with Glucomannan as a supplement ingredient. It has been known to pose a choking risk if taken with insufficient water because it can swell in size in the throat.

It is important to ensure that you always take with sufficient water as the information advises and possibly drink additional water afterwards to stay on the safe side.

Does Slim Fizz Have Any Side Effects?

Slim Fizz should not cause any side effects. According to clinical research, it can be taken safely for up to four months.

Not suitable for individuals under 18. Avoid if you are pregnant or breast-feeding.
See your doctor first if you are taking any sort of prescription medication because Glucomannan may interfere with the way that your medication works and reduce absorption. This also applies to the contraceptive pill.
Some doctors recommend taking oral drugs one hour before or four hours after Glucomannan to avoid decreased or delayed absorption.
Glucomannan may affect blood sugar levels so speak with your doctor if you are taking medication for diabetes.
Do not take if you have difficulties in swallowing.

Any Slim Fizz Reviews From Customers?

There is not much customer feedback for Slim Fizz. There is a five star review on the product website, which reads:

perfect for when I starting eating healthier foods to curb my sugar cravings and appetite. I used to use it everyday but now that my appetite is under control, I only use it when I feel my cravings coming back. I have lost 10lbs since February and it is now April. To say I’m happy with this product is an understatement. I will defiantly be purchasing this again.

Other reviewers are less positive elsewhere but in fairness, they do not appear to have given this supplement much of a chance.

One customer was disappointed after the second day, writing:

This is my second day of using Slim Fizz and I can honestly say I don’t feel any different in terms of hunger pangs!

However after contacting Proto Col she was advised to “eat lots of green vegetables and to lay off the stack of high fructose fruit and eat low glycemic food such as porridge etc.”

Another customer is still awaiting results:

Still to see results but I could definitely tell the difference on day one. I felt immediately full after drinking and it lasts me a good 4-5 hours. Interested to see what happens at the end of the week.

So Does Slim Fizz Work?

We think that Slim Fizz will certainly help some people, especially if you combine it with a diet and exercise programme… However many of the clinical studies have been carried out over months rather than weeks, so you could be in for a long haul.

One preliminary study concluded that:

At doses of 2-4 g per day, Glucomannan was well-tolerated and resulted in significant weight loss in overweight and obese individuals. There is some evidence that Glucomannan exerts its beneficial effects by promoting satiety and faecal energy loss. Additionally, Glucomannan has been shown to improve lipid and lipoprotein parameters and glycemic status

Another test, carried out over two months found that Glucomannan was most effective when combined with an exercise regime, although it did not cause weight loss, only fat loss.

…. exercise appeared to augment the reduction in fat mass (by 63% and 50%; men and women, respectively) and waist circumference, but did not affect total weight loss. Addition of a resistance and endurance exercise training program to a Glucomannan diet regimen significantly improved measures of body composition

What About A Guarantee

Slim Fizz does not come with a guarantee.

Watchdog Verdict

Slim Fizz looks to be a reasonably good supplement. Its one active ingredient Glucomannan has been clinically tested and may help support a weight loss regime. The European Food Standards Agency have investigated Glucomannan and reported that it may help promote weight loss. It seems fair to say that if you combine Slim Fizz with a diet and exercise plan you may find that this supplement offers some support.

However, we do have some reservations. Most of the clinical trials into Glucomannan have been carried out over months rather than weeks so you may have to take this long term in order to see results.

In addition, you will need to be careful to ensure that this supplement does not interact with other medication you may be taking, including the contraceptive pill. Proto Col should have warned customers to take medical advice before using and we are not impressed with this omission.

However If you are interested in trying Glucomannan, Slim Fizz could be a good choice. It is safer in the form of a drink than as a solid supplement. This ingredient is known to cause choking if taken with insufficient water – a fact that does put many people off.

Our major issue with Slim Fizz is the price. At £19.95 for just 10 days supply, it is very expensive. If you take this over months as all the clinical evidence suggests you should, it will work out as a very expensive option.

Our opinion is that although Slim Fizz may be worth a try if you are specifically looking for a Glucomannan supplement, we are not so sure it is good enough to add to our approved list.
