My psychiatrist recommends folic acid - the daily minimum requirement. I take a Woman's formula that has folic acid and B;s; also I take Omege 3 Fish oil supplement. When you chose a fish oil supplement, be sure to only take pharmaceutical grade - free of mercury and other contaminants....that's very important.
I researched it throughly - you can get some good info. on the Environmental Defense Fund's site - they thoroughly researched all of the commercially available ones - you can see this run-down there.
Good luck...
When I took Prozac, I took B vitamins at the suggestion of my shrink. Back then Omega 3 wasn't really used.
Maybe the best thing is to ask your dr or pharmacist.
I would google that. I know that some supplements are ok to take,but need to be spaced out in order to prevent absorption issues.
I too, take b complex and fish oil, vit c, spirulina, adrenal support, magnesium, calcium, zinc, the list goes on and on...
Good luck.
