N1
Irritable bowel syndrome capsules

The N1 irritable bowel capsules made a good impression in our test. The product is a good size for convenient use. The capsules are intended to relieve thepainful symptoms of irritable bowel syndrome, the pressure of excess gas in the digestive tract and abdominal pain in patients with irritable bowel syndrome and normalize bowel activity. According to the manufacturer, when taken up to three times a day, toxins, bacteria and viruses can be adsorbed, preventing them from adhering to the intestinal mucosa. They also allow the gas bubbles in the stomach and intestines to bind more easily, making it easier for gas to pass through. The product is convenient, easy to use and tasteless.

Advantages

✅ Easy to swallow capsules
✅ convenient and easy to use
✅ natural active ingredients
✅ German pharmacy quality

Disadvantages

❌ Small pack size for the specified macimal dose
❌ No indication of the quantity of ingredients

The first impression

Packaging and labeling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

Packaging

The N1 irritable bowel capsules arrived for our test in a typical shipping carton. This was undamaged on arrival and could be easily opened by removing the adhesive strip. This type of packaging optimally protected the product from external influences. Product protection was therefore fully guaranteed and the irritable bowel capsules were delivered in perfect condition .
The packaging is also recyclable. In this respect, the product leaves a very good first impression.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

After unpacking, two blisters containing 15 irritable bowel capsules each and the instructions for use are on the table. The instructions for use provide information on how to use the product. Various free e-books on the manufacturer’s various medical products can be downloaded via a QR code. Contact information can be found on the product packaging and in the instructions for use. However, there is no customer hotline or e-mail address. Overall, this is a well thought-out and customer-friendly way of sending a product.

in the hand

The irritable bowel capsules are supplied in two blister packs. The labeling is discreet and limited to the essentials. Everything that must be stated on a medical product is on the product. As with a medicinal product, the instructions for use are very detailed with general information, explanations of the product and the areas of application, the composition, warnings and possible side effects. There is no information on the sustainability of the product.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

The irritable bowel syndrome capsules from N1 are a medical product with special, tested ingredients such as natural mineral clay and simethicone. The capsules are intended to relieve thepainful symptoms of irritable bowel syndrome, the pressure of excess gas in the digestive tract and abdominal pain in patients with irritable bowel syndrome and to normalize bowel activity. To achieve the greatest possible success, the product should be taken a maximum of three times a day over a period of up to 4 weeks . One pack lasts for about 5 days at maximum intake. The capsules are easy to remove from the blister and can be taken with a glass of water. The taste is neutral.
The company takes customer service very seriously and is happy to answer any questions about the productor treatment.
In order to obtain a meaningful result about the success of the treatment, the test must be carried out over a longer period of time. According to the manufacturer , the active ingredients can adsorb toxins, bacteria and viruses and thus prevent them from adhering to the intestinal mucosa. They also allow the gas bubbles in the stomach and intestine to bind together more easily, making it easier for gas to pass through.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioAppropriate70 points
Rating cut3.9 out of 5.0 on Amazon45 points
Total58 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 3.9 stars. One criticism is that the effect does not occur as hoped. Other reviewers, however, confirm the stated effect and recommend the product. In our test, we were able to confirm that the active ingredient simethicone can indeed alleviate bloating symptoms, but due to the lack of quantity information on the product, it is not possible to check whether the dosage is sufficient.

Prices of up to €25 are charged on the Internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €8. The N1 stimulant bowel capsules are therefore in the middle price segment with a current price of €14.90. Consequently, the price ratio is reasonable for the quality and scope of services that you receive.
