The variety of supplements available at local pharmacies and health food stores may confuse average consumers seeking to improve their moods. The most popular supplements for mood are amino acids, herbs, oils, vitamins and minerals. Some supplements work to directly increase levels of neurotransmitters in the brain, while others work indirectly to support your overall system. Be up-front with your physician about your use of supplements, as they may react with other prescription medications or interfere with treatment of other illnesses.
Types of Depression
Different types of depression, such as anxious depression and low energy depression are caused by different imbalances in the neurotransmitters serotonin, norepinephrine and dopamine, according to Dr Henry Emmons in "The Chemistry of Joy." Serotonin deficiency can leave you feeling lethargic, sad and inadequate. Too much dopamine and norepinephrine can cause irritation and anger, whereas deficiency in these chemicals causes people to feel confused and emotionally absent. Symptoms in depression vary over time, requiring a continuous, mindful effort to create balance.
Amino Acids
Amino acids commonly used in treating mood disorders are 5-HTP, L-phenylalanine, L-tyrosine, L-tryptophan and SAMe. L-tryptophan and 5-HTP increase serotonin. SAMe enhances serotonin and dopamine. L-phenylalanine and L-tyrosine increase dopamine and norepinephrine. Consult your doctor before taking amino acids, and do not take more than one amino acid at a time unless directed by a doctor. Be very careful taking amino acid supplements if you have been diagnosed as bipolar, as they can cause mania, according to Dr. Emmons.
Herbs
The most popular herbs for treating mood disorders are St. Johns wort and kava kava. According to University of Maryland Medical Center, St. John's wort is beneficial for mild depression, but researchers are unsure why. St. John's wort has a long list of side effects and drug interactions, so it should be taken only under the supervision of a doctor. Kava kava is best known for its relaxing properties, making it good for temporary relief of insomnia and anxiety, according to the University of Maryland Medical Center. Long term kava kava use may cause liver damage, and it should be taken under doctor's supervision.
Fish Oil
Fish oil gains more acclaim over time and is even prescribed medically for depression and attention deficit disorder in other countries. According to the article "Fish Oil May Aid Against Manic Depression" in the Washington Post, a Harvard University study showed that bipolar patients had fewer mood swings while taking significant doses of fish oil.
Vitamins and Minerals
According to Dr. Emmons, getting the right amounts of vitamins and minerals is important for balancing mood. B vitamins facilitate the creation of neurotransmitters, reduce stress and prevent depression. Vitamin D helps to treat winter depression. Other important vitamins and minerals include C, E, beta-carotene, selenium, calcium, magnesium, chromium, copper, zinc and manganese.
Considerations
The best source of enzymes, vitamins and minerals is a healthy, balanced diet. Other factors such as exercise, stress, addiction, relationships and emotional trauma affect mood. If you are concerned about your mood, see your doctor for professional help and advice.
