First of all, there is no right and no wrong.
If you wan’t to fulfill the daily nutrition recommendations for an average adult, you have to consume one bag of BERTRAND.
If you want to consume three meals a day, you have to:

  • Fill up with cold water. Marker 750ml.

Prepared BERTRAND must be kept refrigerated (40 degrees Fahrenheit or below) and consumed within 6 hours.
When stored in a cool, dry place BERTRAND pouches have a shelf life of at least 6 month. The refridgerator is a good place for BERTRAND pouches in general.
Yes, we have a vegan version. You can find this option and the considered composition of ingredients in the detail view of the particular package. For our normal BERTRAND we use organic milk powder from German agriculture.
BERTRAND is gluten-free. For an independent analysis of our product, we authorized the Intertek Institute in Bremen, which has many years’ experience as an international company in the field of food analysis. Intertek will be making inspection analyses at regular intervals, the results of which we will provide to you in our FAQ.

We have decided against advertising with the trademarked AOECS Seal, and against applying for AOECS certification. The costs of certification with world-wide distribution would have resulted in our having to raise our prices. That seems imprudent to us at this time, and we hope to win our customers’ trust through the regular release of the independent analysis results.

This analysis is accredited according to DIN EN ISO/IEC 17025.

We use real and healthy foods with no artificial additives or synthetic vitamins.
There are probably two possible opinions one could have about the product safety of the various full-nutrition shake approaches. On the one hand you could be of the opinion that human nutrition has been sufficiently researched. In this case it is possible to select the RDI nutrition recommendations as the sole list of ingredients for your daily food intake. However in our opinion this is not the case. We are assuming that other micro-nutrients will be discovered in future as well. And what will be the situation in five years if perhaps three new essential vitamins are discovered? We think that the chance that these are already contained in a product made of many different natural ingredients, that people have been using as food for centuries, is far higher than in a synthetic product with only the isolated vitamins from the 2015 food recommendation.
A few of the vitamins and mineral nutrients in BERTRAND exceed the recommended guidelines, sometimes considerably. It is obvious that cereal plants like oats do not care about what the recommended guidelines are, for example for Manganese. The exceedance of the recommended guidelines is also not hazardous to your health, because we do not exceed the daily maximum value or TUL (tolerable upper limit) with any of the nutrients.
The glycemic index of BERTRAND has not been tested clinically. A simple calculation of the GI on the basis of the ingredients makes little sense but is requested more often in the support, so here the answer: 42
The organic certification obligates us to act by the rules of the EU-Eco-regulation.
For our product it means that we have to use ingredients from controlled ecologic agriculture. Furthermore, we don’t use synthetic vitamins or minerals, what makes the composition of BERTRAND difficult and more expensive than other products. BERTRAND consists of healthy ingredients like grains, nuts, fruit powder as well as canola- and algae oil.

By the certification it is also secured that no genetically modified organisms are used in our product.
