Folate has been recommended to help in depression and may have a calming effect. There is a prescription form of Metafolin called Deplin which comes in 8 milligrams (or 8000 micrograms), but there is a disclaimer that Metafolin may aid in the growth of tumors/cancer, especially in the GI tract (which makes sense because Metafolin is used in DNA synthesis and rapidly dividing cells need to make DNA). Note it won't cause cancer, but it may aid in the growth/spread of a tumor if it is there. Also if you are going through cancer treatment, don't take folate supplements. Anyways, if you want to see if Metafolin may help your symptoms, this could be a good starting dose with less risk.
