Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. 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 maximum score is 100 points

The vitamin A 10,000 IU capsules from R(h)ein Nutrition can be taken simply with water. The recommended intake is one capsule per day.
The capsules are approx. 19 mm long and 6 mm wide. The size, the pleasant fruity smell and the daily quantity make it easy to take and thus increase the consumer-friendliness of the product.
Each capsule contains 10,000 IU of vitamin A, which corresponds to the usual market dosage. For adults, the tolerable total intake of vitamin A is 3,000 µg/day (=10,000IE).
The filling and coating agents contained are also harmless and have no harmful effects on health.
Unfortunately, the product is only available in a pack of 120 capsules and there are no capsules with other dosages.
This could be a limitation for consumers who want an alternative dosage.
In terms of storage, the manufacturer recommends keeping the tablets out of the reach of children in a cool, dry and dark place. These storage recommendations are sometimes cumbersome but important to ensure the shelf life and efficacy of the product.
The tablets have a shelf life of two years, which is a reasonable period for consumption.
Our practical test shows that the vitamin A 10,000 IU capsules from R(h)ein Nutrition are convincing in terms of ingredients and ease of use.
However, a greater variety of pack sizes and dosages could increase the attractiveness of the product for different target groups.
It should also be noted that it is always recommended to consult a doctor before taking such dietary supplements.
The practical test does not provide any information about the effectiveness of the capsules, as it was not possible to test them during the intended test period.
