• B Vitamins help the body convert food into energy (metabolism), create new blood cells, and maintain healthy skin cells, brain cells, and other body tissues.

  • Deficiencies in B complex vitamins can cause delayed development or worsen symptoms related to learning differences and attention issues in Adults with ADHD.

  • Adequate B Vitamin levels can increase alertness and decrease anxiety-like symptoms in those with ADHD.

The B All & End All

The B Vitamin complex, a group of eight water-soluble vitamins, plays a crucial role in maintaining overall health, particularly in supporting metabolic processes, energy production, and neurological function. These vitamins include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). Each vitamin in the complex has specific roles, but they collectively contribute to critical bodily functions such as red blood cell formation, DNA synthesis, and the proper functioning of the nervous system.

Modern uses of B Vitamin complex supplements often focus on addressing deficiencies, supporting brain health, and enhancing energy levels. They are commonly used to alleviate symptoms of fatigue, improve mood, and support cognitive function. For instance, Vitamin B12 is essential for maintaining healthy nerve cells and can help prevent megaloblastic anaemia, a condition that causes fatigue and weakness. Similarly, folate (B9) is crucial for DNA synthesis and repair, making it vital during periods of rapid growth such as pregnancy and foetal development.

Research has shown that B Vitamins play a significant role in mental health. A study published in the Journal of Human Nutrition and Dietetics highlighted the importance of these vitamins in cognitive function and their potential in reducing the risk of neurodegenerative diseases. The study found that deficiencies in B Vitamins, particularly B6, B9, and B12, were associated with cognitive decline and an increased risk of dementia (PubMed Central, 2016).

Another study emphasised the role of the B Vitamin complex in managing stress and mood disorders. The study published in Nutrients found that supplementation with B Vitamins significantly reduced stress and improved mood in healthy individuals. This is because B Vitamins are involved in the synthesis of neurotransmitters such as serotonin and dopamine, which are critical for mood regulation (PubMed Central, 2019).

B Vitamins play a beneficial role in regulating ADHD. A review published in Functional Foods in Health and Disease indicated that children with ADHD often have lower levels of certain B Vitamins, particularly B6, B9, and B12. Supplementing these vitamins might help manage ADHD symptoms by supporting neurotransmitter function and reducing oxidative stress. Additionally, a study cited in Journal of Dietary Supplements found that a B Vitamin complex, when combined with other nutrients, improved cognitive function and behaviour in children with ADHD (Taylor & Francis Online, 2018).

What the Research Says

  • Hyperactivity and Impulsivity May be Related to Vitamin B12 Levels

  • Lower Concentrations of B vitamins Were Associated With ADHD diagnosis

  • B Vitamins Are Strongly Associated with ADHD.
