This formula is designed to support the neurotransmitters dopamine and serotonin, with the potential to improve problems with sleep and anxiety.* Neurotransmitters are natural messengers in the nervous system that send signals from one nerve cell across a synapse to another nerve cell or target organ. Serotonin plays a role in sleep, mood, intestinal function, pain control, and inflammation. Dopamine plays a role in cognitive function, memory, learning, and pleasure. In our bodies, dopamine is released as a result of rewarding experiences. Certain nutrients and amino acids may help to balance levels of neurotransmitters by providing co-factors that assist in the body’s ability to manufacture neurotrasmitters.* About the Ingredients 4-amino- 3-phenylbutyric acid- Research has shown that 4-amino-3-phenylbutyric acid crosses the blood/brain barrier, and it can also be absorbed more efficiently than GABA (gamma aminobutyric acid). This anxiety-reducing and cognitionenhancing agent is also called phenibut or fenibut. Fenibut has been studied for its ability to prevent the negative effects of sleep deprivation, namely protecting the adrenal glands and reducing cognitive and emotional disorders caused by lack of sleep.(i) It has also been researched for its ability to reduce anxiety.(ii) Phenibut is commonly used in Russia to improve anxiety, sleep disorders, depression, post-traumatic stress disorders, and more.(iii) L-Taurine- is an essential amino acid and a GABA-receptor agonist, meaning it produces a GABA-like effect in the body. GABA is a sedating, inhibitory neurotransmitter. In animal studies, application of taurine with GABA, or taurine with glycine produced stronger effects than taking either glycine or GABA alone.(iv) Taurine is used to enhance sleep quality.(v) L-Glycine- is a non-essential amino acid. It has been used to protect brain cells after ischemic stroke. Glycine is also thought to promote a sense of well-being and reduce anxiety. Research has shown that glycine can subjectively and objectively improve sleep quality.(vi) In a study where people’s sleep was restricted, glycine also reduced daytime sleepiness.(vii) Vitamin B-5 (as d-calcium pantothenate)-is a water-soluble B vitamin with numerous biological roles. Vitamin B-5 is used by the body to manufacture, among other things, coenzyme A which is an important compound for energy metabolism and the production of fatty acids, cholesterol, and the neurotransmitter acetylcholine. D-Calcium pantothenate the preferred, metabolically active form of B-5 used in higher quality nutritional supplements. Vitamin B-6 (Pyridoxal 5-phosphate) – is a water-soluble B vitamin that performs many functions in the body, including as a co-factor in several reactions of amino acid metabolism. Specifically, B-6 – dependent enzymes assist in the biosynthesis of the important neurotransmitters GABA, dopamine, serotonin, epinephrine, and norepinephrine. Pyridoxal 5-phosphate is the preferred, metabolically active form of B-6 used in higher quality nutritional supplements.
