Just read an article in this month's  Nutrition Action Health Letter  that said that a 3-year study of people taking high doses of folic acid were at greater risk of certain cancers, including colon cancers. Although 400 micrograms a day was found to prevent neural tube defects, higher doses were linked to higher rates if cancerous polyps and prostate cancer. The article said that if you were already taking a multivitiamin with 400 micrograms of folic acid in it, you should not take more, because there is also nautally occurring folic acid an a lot of foods. I know a lot of people have advocated taking up to 1 mg of folic acid, particular when they had hair loss. Just wanted folks to know.

Sounds like an interesting newsletter.

The recommendation to take higher amounts of folic acid is because: a) Crohn's patients have problems with absorption of vitamins and minerals, absorbing less than the average person and b) some medications, like sulfasalazine, interfere with folic absorption.

So while 400 might be OK for a healthy person, it might not be enough for a Crohn's patient. Blood tests can reveal whether serum folate is low or falling.

Folic acid deficiency can cause anemia, cognitive decline, and increases the risk of cancer according to the following article:

Hey Squattie, I thought I was the only one who couldn't tolerate Folic Acid. My GI was stunned I couldn't take it, because he said its the easiest supplement to tolerate for most folks. Except you and me of course. LOL
