Biest Booster – an all natural high-tech product

Biest Booster – an all natural high-tech product

Many of you have been receiving experiment packages during the last months. Therefore we once again want to outline what the BOOSTER actually is and how you can take it to get the optimum out of it.

Hard to believe but true, the BIEST BOOSTER is a high-tech product even though it is also a truly natural product. Biestmilch is natural through and through and so are the 100 mg of caffeine contained in the Booster and the sweetener Stevia. They originate from the natural caffeine extract of the guarana fruit and the stevia plant form North and South Amercia. The BOOSTER’s matrix is composed of a dextrose derivative called Emdex®. So in the end, what makes the Booster a high-tech product, is the art of combining 4 grams of Biestmilch with 500 mg of Guarana extract into an edible small shape.


The idea of designing a product that may be able to facilitate the a breakthrough for Biestmilch, had been on our minds for quite some time. Even back in the first days of Biestmilch back in the year 2000, we had thought a product that would able to generate instant gratification for our customer, while Biestmilch regular takes 10 days up to round about 3 weeks to kick in.
After a couple of years of experience we decided to take up the idea of »a product for the impatient« again. We knew enough about Biestmilch and its efficacy to finally dare to develop such a product.

We knew that 4 grams of Biestmilch lift the spirits and help to improve the general well-being under the various conditions such as issues with immunity. Guarana is well known to you as a natural caffeine extract and stimulant supporting cognition. Now the basic idea was there and along with it the problems that usually emerge, when moving from theory to reality. All of a sudden the Biestmilch powder put up some resistance. So did the sorbitol, shape, structure, taste, solubility, brittleness and stability… a number of various problems suddenly popped up and put our theoretical concept to the test.

How to put 4 grams of Biestmilch into an edible shape?

In April 2006 we developed granules, which were neither edible nor possible to swallow in the respective amount. It foamed and frothed inside the mouth in a strange manner and gave any observer a hearty laugh.
As we already had some experience with developing bars, the next test product was a bar with 4 grams of Biestmilch and 500 mg of Guarana. The tiny Biest Booster bar was finished by June 2006. It tasted of bitter orange and was a bit hard, but we quite liked the taste. I am afraid to add, that we remained the only people with this opinion.

A chocolate coating gave the Booster a tastefulness that threatened the healthy aspects of our product. To much guarana may induce flushes, headache and restlessness. We took a step back from this kind of Booster. Another reason to distance ourselves from the bar was that we would then be compared with the gigantic market of bars. But the Booster is unique and incomparable, so we moved to the next testing phase.
In September ’06 we had made it to the first tablet, a square block. It was based on a sorbitol matrix. Because of its laxative effect, if consumed in large amounts, sorbitol was not exactly an option. And sorbitol has a rather narrow bandwidth concerning stability and consistency. Once the machine was even run down, because the block was simply too thick and the sorbitol jammed the machine’s extruder. So we had rock hard bricks, with which one could have very well killed somebody.


This thinking and testing process resulted in the first octagon version. The experiments lasted from February till April 2007. A huge breakthrough for the Booster development was the choice of the matrix Emdex® instead of sorbitol. Emdex® is a very modern dextrose derivative and a far better matrix than sorbitol. Taste and feeling in the mouth were improved greatly. At last, after a series of 8 to 10 different kinds we ended up with a product that could be considered for a broader range of testing. We still had massive problems with the stability of the tablet when trying to pack it. The octagon constantly broke into two pieces when put into the side sealed bag.

When eating the 7,8 g heavy Booster we also still had the problem of a kind of »suffocating sensation« and taste of mouth.


Instead of Biestmilch powder we used agglomerated colostrum. In this testing series all of a sudden the Booster was stable and good to chew. Series 11.1 and 11.2 were mere variations in taste and mouth feeling to optimize »edibility«. With the Booster 11.2.4 the final decision was made for marketing the product. A first production of 4200 pieces left the factory in August 2007.

Since then we have been fine-tuning still, and worked on the mouth feeling. All the years that passed by until today show that those who once tried the BIEST BOOSTER and felt the instant positive effects become loyal consumers.
But the slight bitterness of its taste has ever since been a handicap for the first time user in specific.


Since the beginning of the year it is legal to use Stevia in Germany. Now, finally we could take the last step in the BOOSTER’s development until now, add a very very little amount of Stevia to it. Stevia is 400 times as sweet as sugar. So we had to be very careful in applying it. Now its done, no bitter taste anymore, enjoy chewing the new BOOSTER!
But as you all confirmed in the passed tests the BOOSTER should not become really sweet. So what we did is we only removed the bitter part. The BOOSTER should be still a relief for your gustatory sense that after all the sweet gels and bars you eat.


Guarana from the Portuguese guaraná (Paullinia cupana) is a climbing plant in the maple family, native to the Amazon basin and especially common in Brazil. Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean. As a dietary supplement, guarana is an effective stimulant. It contains about twice the caffeine found in coffee beans (about 2–4.5% caffeine in guarana seeds compared to 1–2% for coffee beans). Compared to the caffeine from coffee beans caffeine in guarana is slowlier released and is therefore active between 4 to 6 hours.
As guarana is rich in caffeine, it is of interest for its potential effects on cognition. In rats, guarana increased memory retention and physical endurance when compared with a placebo. A 2007 human pilot study assessed acute behavioral effects of guarana extract. Memory, alertness and mood were increased confirming previous results of cognitive improvement following the consumption of guarana.

A cup of coffee (150 ml) contains ca. 30 to 100 mg a small Espresso (30 ml) ca. 40 mg caffeine.

Products with natural caffeine content

A cup of black tea contains an average of 50 mg

In former days the caffeine in tea leaves was called theine, chemically its exactly the same as the caffeine in coffee. Only 100 g of dried tea leaves contain more caffeine than the same amount of roasted coffee beans.

Guarana contains 4 to 9 g caffeine per 100 g dried weight.

Cacao contains with 6 mg per cup a little bit of caffeine, but mainly theobromine.

Chocolate contains caffeine as well (milk chokolate ca. 15 mg/100 g, bitter choclate ca. 90 mg/100 g), moreover theobromine and other stimulant substances.



Susann is the biest prototype and head of the team. She is Austrian, has studied medicine, meaning she is a medical doctor and the Biesters' alpha wolf. Susann continuously produces new ideas, is strong in making concepts and is practically always ON FIRE. Without her BIESTMILCH wouldn't be where and what it is today, and anyway - not possible.
