Zero-In from ROOT for a sharp mind and awake spirit

Reduce brain fog, regain a clear mind and be able to concentrate on what is important: That is the goal of the product Zero-In from the U.S. company ROOT. A natural alternative to synthetic stimulants, Zero-In uses a special formulation of amino-acids, turmeric, pine bark, velvet bean seeds, coffee-extract and vitamin D to help our brains fundamentally and quickly. You get the feeling that “a few more lights are on” and a boost of energy has been activated.

Advantages of Zero-In:

  • Strengthens cognitive function: increases attention span and concentration.
  • Provides mental sharpness: increases brain activity, creativity and provides a significant boost of energy

How does Zero-In work?

To understand how and why these rapid effects on brain activation and energy boost are possible, let’s briefly review the messengers. These important substances, also called neurotransmitters, are formed in the brain / nerve-cells. Neurotransmitters transmit information and electrical impulses between the approximately 100 billion nerve cells in the brain. The better and faster the communication between the nerve cells, i.e. the signal processing, the better the regulatory and control functions for the entire body.

Whether coordination of our limbs, thoughts, feelings, mood, hormone formation, digestion, sleep, learning ability, addictions or repair processes: If the messengers themselves or the building substances for the messengers are not sufficiently present, functional disorders with a variety of disturbances inevitably occur. Our physical and mental performance is significantly influenced by neurotransmitters.

About 100 neurotransmitters are known, and the existence of thousands more is still suspected. Neurotransmitters can be classified according to function and structure. The structural differentiations are: Amino acids, peptides and monoamines. As always with natural polarities, a distinction is made between excitatory and inhibitory. However, there are also neurotransmitters that can mediate both functions.

Zero-In: For the increase of the most important neurotransmitters

    • Acetylcholine
      promotes concentration, cognitive processes and is important in learning processes. Acetylcholine is formed from the amino acids glycine and serine via further conversion processes. Forgetfulness and poor brain performance are a clear sign of acetylcholine deficiency.
    • Serotonin
      also known as the happiness hormone. It ensures good or bad moods and also good or bad sleep, because serotonin is converted to melatonin (sleep hormone) in the evening. Cravings for carbohydrates, indigestion, anxiety and low self-esteem as well as difficulty falling asleep, and reduced libido are symptoms of a serotonin deficiency.
    • Dopamine
      Self-drive, motivation, interest, curiosity and ambition are controlled by dopamine. Too low a level usually leads to a downward spiral with apathy, frustration and demotivation. If, on the other hand, the dopamine level is increased, or the basic elements for the formation of dopamine are supplied in greater quantities, love of life, motivation, joy and ambition return – the start of a steep upward spiral. Dopamine is formed from the amino acids tyrosine and phenylalanine, and vitamin C, copper and iron are also important in dopamine metabolism. Note: Dopamine mediates the reward effect of achieving one’s goals. According to our definition, success = goal achievement. Do you prefer to achieve one “big” goal a day or ten “smaller” goals, with the consequence of more reward effects? Are your goals realistic or rather wishful thinking?
    • GABA
      As a counterpart to serotonin and dopamine, GABA (gamma-aminobutyric acid) ensures activation of relaxation and recovery. The vagus/parasympathetic nervous system becomes dominant, the body shuts down into rest mode, which leads to increased repair and regeneration processes. The following symptoms indicate a lack of GABA: excessive feelings of stress, irritability, problems falling asleep because thoughts do not settle down, and shortness of breath.


Our experience with Zero-In

With Zero-In, the effects on the brain and energy balance are very quickly noticeable. From our point of view, the brain metabolism is quickly activated, there is a clearly noticeable boost of energy (physical and mental) and finally a mood lift also follows. The effect has started after 1 capsule in about 15-30 minutes and the lasting effect was felt for 4-6 hours.

Since 1-4 capsules can be taken daily, individual dosage and adaptation to one’s own rhythm is very easy. The brain is the main regulatory and control centre and thus influences all subordinate organs, systems and cells. If the control centre functions better again, the subordinate organs and systems also function better again, from our point of view bio-logically well to understand.
