During the many years we are marketing BIESTMILCH now and have been building up a small but powerful brand we collected lots of positive experiences with BIESTMILCH. Especially in endurance sports it can make a difference as athletes' immunity due to the workload they expose themselves to often happens to be on the edge.

The personal experiences of endurance athletes with BIESTMILCH all over the world encouraged us to pursue our next goal and launch the BIEST BOOSTER as integral part of the race nutrition. First our BIEST BOOSTER Experiment BBEX served the purpose to confirm our assumption that the BIEST BOOSTER makes the difference many athletes need. The feedback we got was overwhelming and left us without any doubts.

Then we did a survey asking athletes some questions related to crucial bodily problems during a competition. The questions pointed to the symptoms that frequently occur in people under enormous stress, and where we assumed the BIEST BOOSTER may unfold its potential and ameliorate the irritating symptoms. 565 people answered to the questionnaire*.

The survey was launched under the title "Are you happy with your race nutrition?"

The results are casting an interesting light upon what's happening to an individual on these long hours until crossing the finish line. The results are surprisingly drastic. Just imagine, 75% of the athletes that took part in the survey experience gut issues during a race. 70% stated that they suffer from cramps. Half of them even complain of cramps and gut issues. 59% are unhappy and 41% seem happy with their race nutrition.

The paramount question that arises from these results is:


Does race nutrition play a central role here?

We think yes, beside the heavy workload, the high body temperature and the fatigue, the food incompatibilities due to stabilizers, preservatives, artificial flavors, underlying food allergies or simply due to the intake of too many carbohydrates compared to the performance intensity and the time needed for the course, the total power put in and the speed one is going in a race can cause these problems.

And one should not to forget that the general condition of the gastro-intestinal system in everyday life and shortly before the race influences the situation during the race.

The answers to the question that was related to the carbohydrate intake during the race varied a lot. 22% of you ingest 35 grams per hour, 23% take 70 grams, 6% take less, and 8% ingest more than 70 grams an hours, while 41% eat carbs when needed.

The next step would be now to find out whether there is a correlation between the amount of carbohydrates taken, the time racing and the problems occurring. This would need a controlled set-up and a meticulous documentation of the race nutrition (at what time, how much). This survey cannot give an answer to this question.

Another interesting question was asking our participants whether they lose focus or concentration respectively once during the race. The majority of 70% (391 people) are drifting away foremost after the first half of the bike course and several times on the run.

The reasons given are fear of having eaten too little food, simple distraction due to fatigue, stomach and/or gut issues, boredom, no motivating competitors around, heat, or feeling the first signs of exhaustion. All the mentioned problems cannot really be cured by taking more gels or electrolytes.

We are convinced, that BIESTMILCH is a serious option to ameliorate the problems that may occur during a race, and therefore is worthwhile to be considered as integral part of the race nutrition.


Looking at the published papers the results are quite homogenous. Gut issues are an extremely widely spread problem among endurance athletes. GI* distress in some studies reaches up to over 80%.

Our own data gave us the figures 75% for GI problems and 70% of problems with keeping up concentration.

The BIEST BOOSTER and BIESTMILCH can make the difference and help you break 75% - 70% barrier.

The BIEST BOOSTER Experiment "BBex" in 2012 with its stunning feedbacks, the drastic result of our own survey on health issues during the race and the study by Raymond J Playford published in May 2010 about the leaky gut syndrome encouraged us to do the next step and promote the BIEST BOOSTER as an integral part of the race nutrition.

The BIEST BOOSTER is unique by interacting with the endurance athlete's physiology in a very special way.

In endurance races the body faces mainly two critical conditions, one is fatigue** and the other are gastrointestinal complications.

Both issues have serious consequences that may finally lead to a DNF.

Brain and gut are tightly connected by hard-wired nerve connections that are essential for well-being during endurance performance. If you are aware of this close relation, you won't be amazed that all kind of stress factors along this path can jeopardize the fragile balance athletes' find themselves in during a competition.


Brain activity and neuromuscular recruitment are interdependent. During racing your brain has to be fully present and awake to guarantee optimal muscular recruitment. If the control circuits of the signal transmission from the brain to the muscle and back are fatigued, cramps may occur followed by exertion and finally exhaustion.

Under the condition of fatigue storms of signals can reach the muscle without being filtered. That brings up cramping. This fatigue is located in the central nervous system not in the muscle. Consequently, you need your brain working at full capacity to retrieve your personal best.


Endurance performance affects the integrity of the intestinal barrier. The prolonged strenuous exercise per se, heat stress, mechanical shearing forces, oxidative burst, reduced blood flow, too high an intake of carbs or drugs such as non-steroidal anti-inflammatory agents are only a few of the many stress factors that may induce an integrity loss of the intestinal barrier.

Integrity loss regardless of its cause is associated with an increased intestinal permeability. Stomach and/or gut start leaking. The selective absorption of nutrients from the gut stops. On the other hand bacteria and toxins penetrate non-selectively into the body interior and harm its balance. The immediate symptoms athletes then are bothered by are cramps, diarrhea, bloating, nausea, vomiting, pains or/and stomach bleeding.

Issues that arise with a time lag are problems that occur due to dysregulations of the immunity.

The BIEST BOOSTER can delay the onset of fatigue and protect stomach and gut

Firstly, the BIEST BOOSTER with its 4000 milligrams of Biestmilch and 500mg Guarana helps keeping you alert and focused, exactly what is needed to get your muscles going. It supports the bidirectional communication between the brain and the muscles.

Secondly, the power of BIESTMILCH unfolds its stabilizing effects along the gut by making the cells more stress- and heat-resistant. Brain and gut are two organs that have hard-wired connections and are influencing each other to a great extent. Fatigue kicks in later or is less pronounced and the gut gets more stable, if you integrate the BIEST BOOSTER into your race nutrition.


a study by Raymond J. Playford and co-workers published in 2010

This study gives evidence about the effects of orally administered bovine colostrum on gut permeability, exercise-induced temperature rise, and gut hormonal profiles in athletes undertaking heavy exercise. The protective effects of colostrum have not only been observed in athletes but also in in vitro gut cell lines.

The harming effect of temperature rises on the cell functions could be buffered by Biestmilch*** (bovine colostrum). It was also able to increase the stress resistance of the epithelial cells. The cells became more temperature resistant and cell death was significantly reduced.

In conclusion, the findings show that in a physiologically relevant sports model, Biestmilch appears beneficial in maintaining the gut stability.

** Fatigue is here used as central or mental fatigue and defined from a physiological viewpoint. Fatigue that affects the communication circuits from the brain to the neuromuscular junctions, that in turn affect neuromuscular recruitment.
*** Biestmilch is particularly rich in immunoglobulins, antimicrobial peptides (e.g. lactoferrin, lactoperoxidase), and other bioactive molecules including cell differentiation factors essential for cell regeneration. Therefore was the proposition that Biestmilch could be helpful in protecting all mucosal linings was very likely.
