Here is a list of safe supplements for depression:
The B vitamin family is a group of water soluble vitamins that are extremely important for all individuals, even our youngest neighbors in the womb. We now know that birth defects of the central nervous system can occur secondary to a lack of folate B-9 during the early development. B-9 folate , B-12 cobalamin, and B-6 pyridoxine are most commonly researched B vitamins.
Folate is found in whole grains, beans and fruits and vegetables. B-6 is found in beans, fish, poultry, dark leafy greens, papayas and oranges. B-12 is naturally found in animal products such as fish, poultry, meat, eggs, and dairy. I would recommend a simple B-complex vitamin if your diet is less than adequate (Fast food 1 – 3 times per week) if you want to emphasize these vitamins I would not go beyond these daily amounts unless prescribed by a physician: Folate 1000 micrograms, B-12 1000 micrograms, B-6 50 milligrams. These are conservative but absolutely safe numbers.
Essential fatty acids are found in all cell membranes. They represent the building blocks of the brain tissue. Barry Sears has demonstrated the effects of omega fatty acids on brain and heart health. I recommend up to 4000 mg of commercial grade fish oil daily. Commercial cod liver oil will give you a boost of vitamin A and vitamin D as well as omega 3 fatty acids. As for omega three fatty acids look at the EPA vs. DHA types. Buy fish oil that has twice as much EPA vs. DHA. The research on the ideal ratio is still out but this is a good rule of thumb. PS remember no more than 400IUs of Vitamin E per day.
