Feeling anxious before a big event is completely normal, but for millions of people, anxiety becomes a daily struggle. Those living with generalized anxiety disorder or panic disorder can experience overwhelming fear, racing thoughts, and sudden panic attacks that make even simple tasks feel impossible.

Researchers from Okayama University have uncovered a possible connection between panic attacks and low levels of vitamin B6 and iron. In their study, patients treated for panic attacks or hyperventilation had significantly lower levels of both nutrients than healthy participants. Because vitamin B6 and iron help the body produce serotonin—a brain chemical linked to mood regulation—scientists believe deficiencies may contribute to severe anxiety in some people. More research is still needed to confirm the findings.

Experts stress that these results don’t mean vitamin supplements are a cure for anxiety. However, maintaining a balanced diet rich in foods such as leafy greens, beans, fish, and other iron- and B6-rich foods may support overall health. Regular exercise, quality sleep, stress management, and seeking professional help when needed also remain important parts of managing anxiety.

While anxiety disorders affect millions worldwide, this research offers another clue into what may influence panic attacks. Scientists hope that understanding the role of nutrition could eventually lead to better prevention and treatment strategies, giving people new hope for managing anxiety and improving their quality of life.
