Researchers at Johns Hopkins University Children's Center found folic acid may suppress allergic reactions and lessen the severity of asthma symptoms. They studied more than 8,000 patients between the ages of 2 and 85 and discovered that those with high levels of folates in their blood reported fewer allergies and were less like to develop asthma.
Researchers say it is too early to recommend treating allergies with folic acid. The study adds to previous research showing the vitamin can help regulate inflammation.
