Taking folic acid supplements may not cut your risk of cardiovascular disease or cancer, according to a recent report.
Analyzing eight clinical trials (with a total of 37,485 participants), the report's authors found that folic acid supplementation was linked to 25 percent drop in homocysteine, an amino acid thought to raise heart disease risk when it occurs at elevated levels. However, they also found that study members given folic acid supplements weren't any less likely to suffer a major heart or blood vessel event than those who took a placebo. What's more, subjects assigned to folic acid supplements did not show a reduced risk of stroke or cancer. In the analyzed trials, folic acid doses ranged from 0.8 mg per day to 40 mg per day.
Previous research suggests that folic acid supplements may be useful in treatment of conditions like ulcerative colitis, asthma, and allergies.
