Vitamin D
Vitamin D has many roles in your body, including the regulation of certain neurotransmitters like dopamine ( 37 ).
Normal, healthy dopamine production depends on a wide variety of factors, but many medical professionals believe that your brain's dopamine production will return to pre-substance misuse levels over a period of 90 days.
This could be a mental illness, stress, not getting enough sleep, drug abuse, being obese, or eating too much sugar and saturated fat. Low dopamine can also be caused by a problem with the adrenal glands.
Getting enough sleep, exercising, listening to music, meditating, and spending time in the sun can all boost dopamine levels. Overall, a balanced diet and lifestyle can go a long way in increasing your body's natural production of dopamine and helping your brain function at its best.
Sex, shopping, smelling cookies baking in the oven — all these things can trigger dopamine release, or a "dopamine rush." This feel-good neurotransmitter is also involved in reinforcement.
Meth and the Brain. Meth releases a surge of dopamine, causing an intense rush of pleasure or prolonged sense of euphoria. Over time, meth destroys dopamine receptors, making it impossible to feel pleasure.
Research has shown that the drugs most commonly abused by humans (including opiates, alcohol, nicotine, amphetamines, and cocaine) create a neurochemical reaction that significantly increases the amount of dopamine that is released by neurons in the brain's reward center.
Try these supplements
Mucuna, known as the velvet bean plant, contains L-dopa, another essential amino acid. Like l-tryptophan, mucuna supplements increase dopamine which can decrease depression. Other helpful supplements include magnesium, Rhodiola Rosea, and St. John's Wort.
However, magnesium inhibits dopamine release. Therefore, magnesium may inhibit calcium-dependent brain function through dopaminergic neurons, and consequently reduce the effect of calcium on ethanol activity.
Results: Serum levels of 25(OH)D and dopamine significantly increased in the vitamin D group, compared to the placebo group (p < 0.05). However, serum BDNF and serotonin levels did not change significantly.
A diet rich in fruits and vegetables can boost dopamine levels, specifically apples, bananas, oranges, watermelon, strawberries, avocados, beets, tomatoes, green leafy vegetables, velvet beans, lima beans, and peas. It is also a good idea to eat foods like milk and dairy products that contain tyrosine.
Dopamine agonists are prescription medications that can be used alone or in combination with other medications to treat a variety of conditions that are a result of dopamine loss.
There is no reliable way to directly measure the levels of dopamine in a person's brain, but there are some indirect ways. Some blood tests measure the levels of neurotransmitters, such as dopamine. However, these do not represent the levels of neurotransmitters in the nervous system itself.
What are the signs of a lack of serotonin and dopamine? Deficits in serotonin and dopamine can cause a host of signs and symptoms, including depressed mood, fatigue, lack of motivation, decreased sex drive, and difficulty concentrating.
Conclusion: Amongst the SSRIs examined, only fluoxetine acutely increases extracellular concentrations of norepinephrine and dopamine as well as serotonin in prefrontal cortex, suggesting that fluoxetine is an atypical SSRI.
Given time and treatment, the dopamine receptors can heal, but damage to an addict's cognitive centers could be lifelong. Research suggests that damage to motor coordination through chronic meth use is similar to what individuals suffering from Parkinson's disease go through.
So how long for dopamine receptors to heal? On average, it may take approximately 14-months to achieve normal levels in the brain with proper treatment and rehabilitation.
Methylphenidate (Ritalin), a stimulant drug used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy, also inhibits the reuptake of dopamine and norepinephrine but is generally not used to treat depression.
