Biotics Research DopaTropic Powder – 4.7 oz. (132g) Biotics Research DopaTropic Powder contains a naturally occurring source of L-Dopa from the Mucuna pruriens plant. Dopamine is largely responsible for regulating physical movement, emotion, and the pleasure and motivation centers of the brain. Why you may need DopaTropic Powder: Vastly complex, the human nervous system coordinates innumerable processes via a host of chemical messengers called neurotransmitters. Neurotransmitters are used for everything from signaling the heart and lungs to function, to enabling the body to sleep so regeneration and repair can occur. Emotions, affect, mood, appetite, and even energy levels are also regulated by neurotransmitters. Unfortunately, neurotransmitters operate within a very narrow confine, and their balance can be easily disrupted by a variety of factors including genetics, immune function, diet, stress, and general chemical toxicity. Dopamine is an excitatory neurotransmitter that is important for regulating physical movement, emotion, and pleasure and motivation centers of the brain. It also plays a neurocognitive role, particularly with memory, problem solving, motivation, learning, and the ability to focus. Additionally, dopamine acts on the sympathetic nervous system, thus it impacts physiological functions such as heart rate, blood pressure, and libido. Why your healthcare practitioner recommends DopaTropic Powder: DopaTropic Powder is one of the newest additions to the Biotics Research line of fine nutritional supplements and is part of the NeuTropic triad of products (PheniTropic, NeuPerzine, and DopaTropic Powder). L-Dopa, (aka levodopa; L-3,4-dihydroxyphenylalanine) is a naturally occurring dopamine precursor that is derived from the Mucuna pruriens plant. L-Dopa is an amino acid which is converted to the catecholamine neurotransmitter dopamine.
