Vitamin B (referring to the B vitamin complex, which includes B1, B2, B3, B5, B6, B7, B9, and B12) has been explored for its potential role in managing symptoms of Attention Deficit Disorder (ADD) or Attention Deficit Hyperactivity Disorder (ADHD). The rationale stems from the role of B vitamins in neurological function and neurotransmitter synthesis, particularly vitamin B6 (pyridoxine), which is involved in the synthesis of serotonin, dopamine, and norepinephrine—neurotransmitters implicated in ADHD. A few small studies and case reports have suggested that some children with ADHD might have lower levels of certain B vitamins, and supplementation may lead to mild behavioral improvements, especially when a deficiency is present. For example, some research indicates that vitamin B6, combined with magnesium, may reduce hyperactivity in children. However, these studies often have methodological limitations, such as small sample sizes, lack of rigorous controls, and inconsistent results. Larger, well-designed clinical trials have generally failed to show a significant benefit of B vitamin supplementation in reducing core ADHD symptoms in the general population of individuals with the disorder. Major guidelines and expert reviews do not recommend routine use of B vitamins for ADHD management except in cases of documented deficiency. Therefore, while there is a theoretical scientific basis and limited preliminary evidence, the overall scientific validation remains weak.
