I've been taking 15 mg deplin for nearly 6 months and it seems to be working quite well. I'm a single and disabled mom and don't get child support. My parents have been paying for itit, but it isn't fair to them. I went to see my psychiatrist yesterday who looked it up. He thinks that if I were to take folic acid, calcium and magnesium that it would be equivalent to the active ingredients in deplin. Is this true? If it is, what would the amounts of each supplement be to equal the 15 mg deplin? I can't afford to stay on the deplin anymore, so any information will be greatly appreciated!!! Thank you in advance for any and answers, information and time.
