The human brain uses essential nutrients, such as folic acid and the omega-3 fatty acids found in cod liver oil, to function properly. Folic acid, or vitamin B-9, helps your body produce and maintain new cells. Both nutrients also play crucial roles in maintaining cognitive and behavioral functions. Not getting enough omega-3 fatty acids and folic acid may make you irritable and mentally sluggish.
Uses of Cod Liver Oil and Folic Acid
Cod liver oil is purportedly useful in alleviating depression, psychosis and attention deficit-hyperactivity disorder, notes MedlinePlus, a service of the National Institutes of Health. Cod liver oil may also be used in lowering blood pressure and triglyceride levels. Cod liver oil also seems useful in lowering the risk of developing heart disease and stroke. Folic acid may also be helpful for treating depression. Studies suggest that 15 percent to 38 percent of people who suffer from depression have low levels of folic acid, reports the University of Maryland Medical Center. Low levels have folic acid have been correlated with the inefficacy of antidepressant medication.
Dose
When taking it as a general supplement for health, the recommended dose of cod liver oil is 3 g per day. The dose of cod liver oil used to fight depression is 9.6 g per day, according to MedlinePlus. The recommended daily adult dose of folic acid is between 400 mcg to 500 mcg. Pregnant women need about 6 mcg of folic acid. When folic acid is used in tandem with antidepressants the daily dose is increased to between 200 mcg to 500 mcg. Despite their purported benefits, cod fish liver oil and folic acid are meant to complement and not replace conventional antidepressants.
Side Effects
Cod liver oil may have side effects such as allergic reactions resulting in hives, breathing difficulties and swelling of the face. Seek immediate medical assistance if you experience irregular heartbeats, fever and chills and chest pain. Both folic acid and cod liver oil cause stomach upset, nausea and diarrhea, although side effects due to folic acid are rare, reports the University of Maryland Medical Center
Dietary Sources
Cod liver oil comes from codfish but the omega-3 fatty acids in cod liver oil can also be found in tuna, herring, trout, anchovies and salmon. Folic acid is contained in cereals as well as leafy green vegetables like spinach, broccoli and lettuce. You can also find folic acid in bananas and melons.
