Dopamine is a neurotransmitter affecting brain activity and the cardiovascular system. Exposure to polychlorinated biphenyls (PCBs), a form of toxic chemical pollution, can reduce dopamine to dangerously low levels, affecting the cardiovascular system. Increased dopamine levels can elevate blood pressure and heart rate. Dopamine at high levels is linked to excitability and alertness. Excessively high dopamine levels have been associated with psychosis, so reducing dopamine levels may be a desirable outcome in treating individuals with mental issues. Natural ways to reduce dopamine levels include a balanced diet. Medical intervention in the form of prescription treatments may also be necessary.
Eat a balance of carbohydrates and proteins. Carbohydrates can lower dopamine levels to induce a calmer state of mind. Protein-rich foods like lean meats and nonfat dairy products absorb amino acids that regulate dopamine production in the brain.
Eat vitamin-rich green vegetables to release endorphins that counter-balance carbohydrates.
Be aware of external factors that reduce dopamine, such as chronic stress, B-vitamin deficiencies, low iron and zinc levels, estrogen deficiency (in women), excessive alcohol and narcotics consumption and flu.
Know that illegal stimulants, such as amphetamines, can spur dopamine production and worsen the effects of excessive dopamine.
Consult a physician who can prescribe a dopamine blocker or inhibitor in pill or injection form. These blockers can last up to sixe weeks between doses and are designed to complement therapies for medical conditions including psychosis, hyperactivity and cardiovascular disorders.
