What is Deplin?

Folate is a type of B vitamin that is naturally found in many foods. Folic acid is the synthetic version of folate that is added to processed foods or vitamin and mineral supplements. The body needs folate to produce red blood cells.

Not having enough folate (folate deficiency) can be caused by certain diseases, by taking specific medications, or by not consuming enough folate in your diet. Folate deficiency can result in a lower number of red blood cells, known as anemia. It can also lead to high levels of a certain amino acid in the blood, a condition called hyperhomocysteinemia (HYE-per-HOE-moe-sis-tin-EE-mee-a).

Deplin is a medical food for people who have conditions related to folate deficiency. This medicine is also used in individuals with major depressive disorder who have folate deficiency, or in those with schizophrenia who have hyperhomocysteinemia related to folate deficiency.

Deplin is not an antidepressant or anti-psychotic medication. However, it may enhance the effects of antidepressant medications.

Deplin may also be used for purposes not listed in this medication guide.
