Obethin Facts

  • The supplement is manufactured in the Czech Republic by Medinox s.r.o.
  • Costs £29.00 for 120 capsules (20 -40 days supply)
  • The principle ingredient of Obethin is Glucomannan

Obethin looks like a relatively new diet pill on the market that offers a simple and easy way to lose weight. It is in capsule form and contains fibre and gum ingredients that when ingested will swell up and fill in your stomach. The result is that you will feel fuller before each meal and in addition, it may help prevent against hunger pangs and stomach acid that many people experience when they are hungry.

According to the Obethin website, Obethin is new to the UK. It is supplied by Pharma Danare Ltd a company who are based in Henley on Thames and listed, according to business sources as pharmacy goods wholesalers. However, Obethin is based in Durham.

The supplement is manufactured in the Czech Republic by Medinox s.r.o. for Danare Pharma UK Ltd in a pharmaceutical manufacturing facility that fully meets the strict quality standards of ISO 9001:2009.

According to the product information. Obethin contains;

A vegetable complex of natural polysaccharides that are not absorbed or digested by your body. These natural polysaccharides safely absorb large quantities of water and form a stable, viscous gel which partially fills the stomach and produces a sense of fullness.

This seems like a fair description to us and although we were unable to see an ingredients list on the website, this information was available on where a clearly printed label was visible complete with amounts quantities.

Your body goes through three stages when you take the capsules.

  • In the first period and before you eat your food, the capsules dissolve and increase in volume forming a “stable and viscous” gel. Your stomach is then half-full and you feel less hungry when you eat.
  • As you eat, the gel mixes with the food and slows down the digestion process.
  • Your stomach signals your brain that you are full and even though you have only eaten a small meal you feel satisfied.

The problem with this method of weight loss is that we don’t always eat because we are hungry.

You will need to add some willpower to cut out fattening snacks and drinks and for some people simply cutting back at meal times may not actually help them lose weight. There are many reasons why we over eat. Hunger at mealtimes is not always the main culprit.

To use Obethin, take 1 or 2 capsules with a glass of water, 30 minutes before you eat.

Obethin Concerns:

  • We would have liked to have found out more about the origins of the Spirulina
  • May pose a choking risk if you do not take with sufficient water
  • May not work quite as well as described

So What Is Obethin and What Are The Ingredients For Obethin?

Obethin is a diet capsule that may help cause feelings of satiety.

Each Obethin capsule contains 670mg of active ingredients.

  • Glucomannan (500mg): This is the principle ingredient and a pectin-like, indigestible fiber believed to cause weight-loss. Because the stomach cannot digest Glucomannan, it stays in the gut for a long time and creates a feeling of fullness and appetite suppressant effect.
    Glucomann has been studied by the European Food Safety Agency (EFSA)/ They report that 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 order to get any effect from this ingredient.
    If you took two capsules of Obethin, this would tie in with this recommended amount.
  • Flax Seed Fibre (70mg): Flax is a great source of fibre and also contains omega 3 fatty acids when the whole seeds are taken. There is evidence that that flax seed fibre can help to reduce cholesterol.
  • Sodium Alginate (35mg): Seaweed extract that absorbs water very quickly and will help create the viscous gel in the stomach. According to a study by the University of Newcastle Sodium Alginate may help reduce human fat intake by up to 75% but it requires further evidence.
  • Xanthian Gum (30mg): Polysaccharide derived from natural bacterial sources and commonly used as a food-thickening agent. Here to add bulk to the capsules.
  • Spirulina Platensis (30mg): Natural algae produced for consumption and mainly found in USA, China, Thailand and India. It is a complete protein so called because it contains all essential amino acids and it may have health benefits. However there are some concerns about contamination found in supplements and Spirulina from China has been found to contain lead, mercury and arsenic. We do not know where this Spirulina comes from.
  • Chromium Picolinate 0.161mg.: Chromium. This may help reduce carb cravings but there is no real evidence that it does. At high levels, Chromium can be dangerous for health (it is a trace mineral) but here in low and safe quantities.

Obethin also contains 5mg magnesium Stearate.

So What Does All This Mean?

Obethin looks pretty good. If you take two capsules each time you will be taking the recommended dose of Glucomannan as advised in European guidelines (although clinical studies are showing you need to consumer 3g per day). It may help weight loss because Glucomannan does seem have proven effects in helping to reduce the appetite.

The other ingredients will help create the gel and we can see that this will probably work as described by swelling in your stomach to cause a feeling of satiety.

We are not so keen on the Spirulina. Many people take Spirulina as a supplement and it has been investigated as a stopgap protein for famine victims but there are concerns about contamination. If Spirulina is uncontaminated, it is probably safe but contaminated Spirulina is potentially dangerous, can cause serious liver and kidney problems. We would like to have seen more details about the origins of this ingredient (preferably USA produced) in order to guarantee its safety.

Does Obethin Have Any Side Effects?

There may be side effects. According to the product website, you may experience mild intestinal problems such as constipation, diarrhoea and acid reflux as a side effect from the Glucomannan.

It is essential to ensure you take with plenty of water to prevent Glucomannan posing a choking risk as it swells. It is important to make sure you swallow the capsule whole so that the swelling effect takes place in the stomach and not the throat.

We were unable to find any independent customer feedback so we cannot bring you any real life experiences.

Caution: Avoid if you are pregnant or breast-feeding. Seek medical advice if you are taking prescription medication because Glucomannan can prevent ingredients from being absorbed. If you are taking the contraceptive pill, you are advised to take 20 -30 minutes before you take Obethin. Ensure you drink plenty of water to prevent choking.

Any Obethin Reviews From Customers?

We could not find one independent customer review. There are customer testimonials on the Obethin website and unsurprisingly these customers have found that this supplement helps.

One customer reported;

I am 58 years old and I have been trying to lose about 5 kg. I have done sports regularly, I played tennis, but I was not able to reduce my weight. Approximately, in the mid August I have started to apply Obethin treatment. At this point, I am minus 5 kg. It works great. I recommend it to everyone.

Sounds good but there are very few testimonials and most of them date back a few years. This one was written by “Stan” in 2012.

So Does Obethin Work?

We think it may work to reduce your appetite and if you use this in combination with some exercise and a sensible diet it may help you lose weight. The problem may be that your stomach will be dependant on the full feeling and may adjust to compensate. You may find that it does not work as well once your body becomes accustomed to this artificially full effect. You may also find that it does not prevent you from snacking.

We feel that really the best way to reduce your calorie intake is to eat more dietary fibre to get the fuller feeling naturally. That way you can change your eating habits gradually and find a healthy way to live without becoming reliant on pills.

Where Can I Buy Obethin?

You can buy Obethin direct from the product website.

One bottle of 120 capsules (between 20 – 40 days supply) costs £29.00 and includes free shipping to UK addresses.

Obethin is also available via for £17.57, which is a much better deal and also includes free shipping.

Obethin is not available direct to US customers so you would have to contact the company to find out costs and shipping details.

What About A Guarantee

There appears to be no money back guarantee on offer.

Watchdog Verdict

We quite like the look of Obethin. This supplement will probably help you to lose weight and it may help reduce hunger pangs. Taken in combination with some diet and exercise it may help you. However, the principle weight loss ingredient here is Glucomannan and this is an expensive way of buying this ingredient, which is obtainable from health food shops.

We are concerned about the Spirulina and although it is probably safe we would liked to have seem some assurance that it is free from contamination and where it was harvested from.

We do not like the fact that we were unable to find a single independent review and we do not like that it comes without a guarantee.

Obethin might be worth a try but when it comes down to it, we do not think it is quite good enough to make onto our approved list.
