Drugs are often prescribed to balance brain chemistry. Depressed
patients are given medication to restore balance to the neurotransmit-
ters. Prozac, Elavil, Buspar, Aventyl, Tofranil and Zoloft are antide-
pressants that affect the balance of serotonin and norepinephrine.
(Tranquilizers, such as Valium and Ativan, have a different function
and affect other neurotransmitters.) But these medications have side
effects, including reductions in glutathione, the most powerful
antioxidant that protects the brain from damage.
Brain Function and EPA
One of the most important brain nutrients is the omega-3 fat EPA
(along with DHA). Most people won’t get enough from food, so sup-
plementation is often necessary. The omega-3 fats are key ingredients
for the development and repair of the brain, especially the eyes.
Imbalances in essential fatty acids — particularly deficiencies in
omega-3 fats — have been implicated in depressive disorders in
adults and behavioral problems in children and adolescents, includ-
ing Attention Deficit Hyperactivity Disorder, difficulties with learn-
ing, impulsivity, hyperactivity, aggression and anger.
Researchers continue to identify the positive effects of EPA on the
brain and also have established a direct link between an imbalance in
fatty acids and depressive disorders. In fact, it appears that these fats
regulate neurotransmitters in ways that mimic the effect of some anti-
depressant medications. These fats coat the brain-cell membrane,
serving a protective function when neurotransmitters are fired in the
synaptic phase.
EPAand DHAhave other benefits in brain function as well. They
are most vital for the fetus and child during development of the brain.
They may also help control the release of the stress hormone cortisol,
resulting in improved brain function. And, they may help reduce the
severity of degenerative brain diseases that lead to memory loss and
dementia, including Alzheimer’s disease.
Other Brain Requirements
The brain’s 200 billion cells also have numerous nutritional require-
ments for good function. These include a number of vitamins and
minerals, and most importantly, water. Any dietary inadequacy can
