Big Zone Shelter 2.0 450g

The new Big Zone Shelter
If you don't move with the times, you'll be left behind. And so we constantly strive to adapt our formula to the latest scientific findings, trends, and legal requirements. Who wants products that are no longer up to date? We always strive to be the best and offer you state-of-the-art products, which is why we've also given our popular pre-workout booster, the Shelter, a makeover.

The new BigZone Shelter now relies even more on the synergies between the individual ingredients to make what's inside even more effective.

What exactly is in it?
L-Citrulline DL-Malate
These days, citrulline is a must-have in any booster. This amino acid plays a key role in our body, serving as a precursor to arginine, which in turn can be converted into nitric oxide (NO). NO, in turn, has the function, among other things, of promoting vasodilation of blood vessels, i.e., widening them. This is intended to increase blood flow and thus the pumping effect.

The reason why we rely on citrulline in our BigZone Shelter instead of using arginine directly is that studies have observed that taking citrulline increases the arginine level in the blood more than taking arginine itself. The reason for this is that citrulline is better absorbed through the intestines and is less broken down by the liver through the so-called first-pass effect.

By using L-citrulline, more substrate is available in the blood to efficiently promote the pump effect.

L-tyrosine
L-tyrosine is another important amino acid in our metabolism and is involved, for example, in the synthesis of thyroid hormones and also serves as a precursor to dopamine, adrenaline and noradrenaline.

Studies have shown that taking L-tyrosine before training not only reduced the perception of stress but also increased alertness and thus improved training performance, especially under extreme conditions.

Guarana extract
Guarana is a natural source of caffeine, where the stimulant is bound to natural plant compounds and is therefore released more slowly into the bloodstream. Almost 150 mg of the total 399.6 mg of caffeine in BigZone Shelter comes from guarana, ensuring a consistent effect even during longer workouts, without a sudden drop.

OxyStorm®
OxyStorm® is a patented amaranth extract that contains high levels of natural nitrates. Studies have shown that natural nitrates can increase blood flow and thus enhance the pump effect. Researchers have also observed a reduction in blood pressure and an improvement in the work capacity of athletes.

L-theanine from green tea extract
Studies have shown that the amino acid L-theanine has calming effects without causing drowsiness. Research has also shown that it can reduce the subjective perception of stress and thus also exert significant adaptogenic effects.

Furthermore, recent study reviews show that L-theanine may act synergistically with caffeine and that the two substances in combination improve attention, cognitive performance and subjective perception of mental fatigue more than both substances considered in isolation.
caffeine
Caffeine is probably THE core ingredient of any workout booster. In fact, it's also one of the few effective stimulants approved for use in supplements and arguably the most widely consumed stimulant worldwide. It not only helps increase alertness but also concentration.

The mechanism of action is based on caffeine blocking the receptors for adenosine. Adenosine serves as a signaling molecule in our body, signaling tiredness to our brain so we can rest. If its receptors are blocked, the tiredness signal is no longer transmitted, and, in simple terms, we simply stay awake.

For this reason, studies have also shown that caffeine in amounts of 3 to 6 mg per kilogram of body weight increases strength performance and work capacity during strength training. BigZone Shelter contains almost 400 mg of combined synthetic and natural caffeine per serving, the maximum permitted amount. This amount should correspond to the 3 to 6 mg/kg limit for most athletes.

Cognizin®
Cognizin® is a patented raw material that provides citicoline, also known as CDP-choline. This substance consists of cytosine and phosphocholine and is broken down in the body into choline and cytosine. The cytosine is then later broken down into uridine, which plays an important role in our central nervous system.

The choline from the Cognizin® in the BigZone Shelter, in turn, serves the brain as a basic substance for the production of acetylcholine, an important neurotransmitter that plays a key role in concentration and cognitive performance.

L-Norvaline
Contrary to what its name suggests, L-norvaline is not an analogue of the amino acid valine, but of isoleucine. L-norvaline is able to inhibit the enzyme arginase and thus reduce the breakdown of arginine in the blood. This makes more arginine available in the blood to be converted into nitric oxide by the enzyme NO synthase. We used it in the BigZone Shelter with the intention of synergistically supporting the effectiveness of L-citrulline.
Pine bark extract
The main active ingredient in pine bark extract is a series of proanthocyanidins. These have been shown to increase the activity of the enzyme NO synthase, thus enhancing the conversion and production of nitric oxide. Thus, pine bark extract represents another potentially synergistic substance in the BigZone Shelter pump matrix.

KannaEase®
KannaEase® is a patented raw material derived from a traditional South African medicinal plant called Sceletium Tortuosum, also known as "Kanna." Research has shown that this herb improves mood and concentration, among other things, which we believe can only benefit productive training.
Black pepper extract
Black pepper, or rather the piperine it contains, is known to promote the bioavailability of various substances. Scientific studies suggest that piperine supports the effects of the amino acids and pine bark extract contained in BigZone Shelter, among others, and could thus contribute to an improved effect.

Vitamin B6
Like all vitamins, vitamin B6 is, among other things, an important cofactor for activating metabolic processes. Strictly speaking, vitamin B6 is involved in over 100 metabolic reactions in our body. One of these, which we wanted to harness at the BigZone Shelter, is the conversion of the amino acid L-tyrosine into dopamine and later into adrenaline and noradrenaline by the enzyme L-dopa decarboxylase.

How do I take the BigZone Shelter?
As a pre-workout booster, BigZone Shelter should be taken approximately 30 minutes before training. One serving corresponds to 15 g of powder, or 1 level scoop, in 500 ml of water.
