Question:
Has anyone had any success trying high doses of folate/folic acid as a supplement to Prozac/other SSRIs? FOLIC ACID SUPPLEMENTS FOR DEPRESSION A November 2000 study shows that folic acid supplements are a simple way to greatly improving the antidepressant action of fluoxetine (Prozac) and probably other antidepressants. In addition to improving the effectiveness of fluoxetine, folic acid supplements also greatly reduced the side effects of fluoxetine. This study concludes that folic acid levels used should be sufficient to decrease plasma homocysteine and that men require a higher dose of folic acid to achieve this than do women.

I haven’t used them for depression, but my folate level (along with B12) is one of the things that my pdoc screened for the first time he saw me. And when my depression recently got worse again, he got another level, because he said that anticonvulsants, which I take for bipolar, often decrease folate levels. However, mine was fine. But I do take B-complex.

I’m not familiar with use of folic acid. But I do know women respond better to different B vitamins than men do. B-6 is one that most women find very effective. Christina

I don’t know the ideal dose of folate supplementation. It looks like 500 microgram of folate per day is sufficient for most women, according to the trial (below), with men requiring more. Folate is usually sold by pharmacists in tablets of around 500 microgram — typically taken once daily by women (for pregnancy/menstruation). But it’s also sold by pharmacies in 5 milligram tablets, which is 10X that dose. There are no adverse effects from taking a high dose of folate in a healthy person — it’s a water-soluble vitamin. So men could probably do with taking that sort of dose (5 mg) daily. Enhancement of the antidepressant action of fluoxetine by folic acid: a randomised, placebo controlled trial. Coppen A, Bailey J MRC Neuropsychiatry Laboratory, West Park Hospital, KT19 8PB, Surrey, Epsom, UK. BACKGROUND: A consistent finding in major depression has been a low plasma and red cell folate which has also been linked to poor response to antidepressants. The present investigation was designed to investigate whether the co-administration of folic acid would enhance the antidepressant action of fluoxetine. METHODS: 127 patients were randomly assigned to receive either 500 microg folic acid or an identical looking placebo in addition to 20 mg fluoxetine daily. All patients met the DSM-III-R criteria for major depression and had a baseline Hamilton Rating Scale (17 item version) score for depression of 20 or more. Baseline and 10-week estimations of plasma folate and homocysteine were carried out. RESULTS: Patients receiving folate showed a significant increase in plasma folate.This was less in men than in women. Plasma homocysteine was significantly decreased in women by 20.6%, but there was no significant change in men. Overall there was a significantly greater improvement in the fluoxetine plus folic acid group. This was confined to women where the mean Hamilton Rating Scale score on completion was 6.8 (S.D. 4. 1) in the fluoxetine plus folate group, as compared to 11.7 (S.D. 6. 7) in the fluoxetine plus placebo group (P<0.001).A percentage of 93. 9 of women, who received the folic acid supplement, showed a good response (>50% reduction in score) as compared to 61.1% of women who received placebo supplement (P<0.005). Eight (12.9%) patients in the fluoxetine plus folic acid group reported symptoms possibly or probably related to medication, whereas in the fluoxetine plus placebo group 19 (29.7%) patients reported such symptoms (P<0.05). LIMITATIONS AND CONCLUSIONS: Folic acid is a simple method of greatly improving the antidepressant action of fluoxetine and probably other antidepressants. Folic acid should be given in doses sufficient to decrease plasma homocysteine. Men require a higher dose of folic acid to achieve this than women, but more work is required to ascertain the optimum dose of folic acid. J Affective Disorders 2000 Nov;60(2):121-30

Yeah the ideal dose of folate is a mystery to me too. I’d like to thank whoever posted the original reference. I chow down 10 or more 400 mcg folates whenever I remember; I’d like to take a higher dose supplement but for some reason the federal legislature thought they could be better health care providers than doctors and limited pill forms to that amount.

Andy, The amount you’re taking is a huge overdose and can be harmful! Please, cut it down to 1000 or maybe 1500 mcg at most. Here’s an abstract that should be of interest (emphasis added): Prog Neuropsychopharmacol Biol Psychiatry 1989;13(6):841-63 Folic acid and psychopathology. Young SN, Ghadirian AM Department of Psychiatry, McGill University, Montreal, Quebec, Canada. 1. The incidence of folic acid deficiency is high in patients with various psychiatric disorders including depression, dementia and schizophrenia. 2. In epileptics on anticonvulsants, folate deficiency often occurs because anticonvulsants inhibit folate absorption. In these patients folate deficiency is often associated with psychiatric symptoms. 3. In medical patients psychiatric symptoms occur more frequently, and in psychiatric patients symptoms are more severe, in those with folate deficiency than in those with normal levels. 4. Many open studies have demonstrated therapeutic effects of folate administration on psychiatric symptoms in folate deficient patients. 5. SEVERAL PLACEBO-CONTROLLED STUDIES HAVE NOT DEMONSTRATED THERAPEUTIC EFFECTS, POSSIBLY BECAUSE THE DOSES THEY USED (15-20 mg/day) ARE KNOW TO BE TOXIC AND TO CAUSE MENTAL SYMPTOMS. 6. Two placebo-controlled studies have demonstrated beneficial effects of folic acid administration, one in patients with a syndrome of psychiatric and neuropsychological changes associated with folate deficiency and the other in patients on long-term lithium therapy. In the latter study the dose was only 0.2 mg/day. 7. Folic acid deficiency is known to lower brain S-adenosylmethionine and 5-hydroxytryptamine. S-Adenosylmethionine, which has antidepressant properties, raises brain 5-hydroxytryptamine. Thus, depression associated with folate deficiency is probably related to low brain 5HT. 8. S-Adenosylmethionine is involved in many methylation reactions, including methylation of membrane phospholipids, which influences membrane properties. This may explain the wide variety of symptoms associated with folate deficiency. 9. Because the costs and risks associated with low doses of folic acid (up to 0.5 mg/day) are small, folic acid should be given as an adjunct in the treatment of patients with unipolar or bipolar affective disorders and anorexia, epileptics on anticonvulsants, geriatric patients with mental symptoms and patients with gastrointestinal disorders who exhibit psychiatric symptoms. 10. Although the majority of the patients listed above will probably not be helped by folic acid therapy, a significant minority are likely to have folate-responsive symptoms. good to "see" you <g>, -elizabeth
Response:
Some studies have shown that people who are nonresponsive to SSRIs, in particular, tend to improve with folate — that folate deficiency is what keeps them from responding to the ADs. As many as 2/5 of patients with major depression may be folate deficient (probably more like 1/4). Men appear to require higher doses than women. In general, around 500-1000 mcg is probably adequate for anyone with a folate deficiency. (That’s *micrograms*, not milligrams (the equivalent in mg is 0.5-1000 mg). Don’t take 5 mg of folic acid! It can be toxic.) I think most folate supplements you can get in drug stores over the counter are 400mcg (0.4mg); my dad takes a 1mg supplement by prescription (he has well-controlled heart disease, thanks to meds, surgery, dietary changes, and exercise). I don’t think it works terribly well except in people who are deficient in folate so you shouldn’t expect miracles if your folate levels are normal. BTW, this might be a first step in explaining the connection between depression and cardiovascular disease. That’s pretty cool. Here’s an abstract that explains a little about the current theories regarding folate and depression: Nutr Rev 1996 Dec;54(12):382-90 Folate, vitamin B12, and neuropsychiatric disorders. Bottiglieri T, Kimberly H. Courtwright and Joseph W. Summers Institute of Metabolic Disease, Baylor University Medical Center, Dallas, Texas, USA. Folate and vitamin B12 are required both in the methylation of homocysteine to methionine and in the synthesis of S-adenosylmethionine. S-adenosylmethionine is involved in numerous methylation reactions involving proteins, phospholipids, DNA, and neurotransmitter metabolism. Both folate and vitamin B12 deficiency may cause similar neurologic and psychiatric disturbances including depression, dementia, and a demyelinating myelopathy. A current theory proposes that a defect in methylation processes is central to the biochemical basis of the neuropsychiatry of these vitamin deficiencies. Folate deficiency may specifically affect central monoamine metabolism and aggravate depressive disorders. In addition, the neurotoxic effects of homocysteine may also play a role in the neurologic and psychiatric disturbances that are associated with folate and vitamin B12 deficiency. -elizabeth

Folate 5 mg tablets should not be toxic to a healthy person. The 5 mg tablets are sold over-the-counter in Australia. It is a water-soluble, B vitamin. However, folate interacts with the trimethoprim/sulphonamide antibacterials, some anticonvulsants, sulphasalazine, methotrexate and other drugs.

Elizabeth, Thanks for taking the time to point this out to me. I had no idea and will cut the dose down to 2X 400mcg a day. I hope all is well. Andy

Response:
The reference below says that 15-20 mg folate/folic acid is toxic. But not 5 mg, or 10 X 400 micrograms. I have the label of the over-the-counter folic acid 5 mg tablets from Sigma Pharmaceuticals, 1408 Centre Rd, Clayton, Vic 3168, Australia — a reputable manufacturer of ethical pharmaceuticals: "Dose: Take one tablet daily or as directed by physician." There is a rigorous Poisons Act in Australia. If folic acid was toxic at this sort of dose, it would certainly not be available in pharmacies over-the-counter, to say the least. The B-vitamins (including folate) are water-soluble. It is generally the fat-soluble vitamins (eg A and D) that can have serious toxicity problems. The trial below states that: "Folic acid should be given in doses sufficient to decrease plasma homocysteine. Men require a higher dose of folic acid to achieve this than women, but more work is required to ascertain the optimum dose of folic acid." The dose given in the trial was 500 microgram daily, but this was insufficient for most men in the study. A significantly higher dose may be required. – Hide quoted text — Show quoted text -> Elizabeth, > Thanks for taking the time to point this out to me.
