- Context: This article explores the role of dietary supplements in managing Attention-Deficit/Hyperactivity Disorder (ADHD). It highlights that while supplements are not a replacement for prescription medication, they can be a beneficial part of a holistic treatment plan, helping to achieve healthy micronutrient levels and improve focus and concentration. The discussion is particularly relevant given recent nationwide medication shortages.

- Detailed Summary:
- Omega-3 Fatty Acids: These have the strongest evidence for supporting brain function in individuals with ADHD, as many diagnosed with the condition are found to be deficient. Supplementation has shown improvements in attention, visual learning, short-term memory, hyperactivity, and impulsivity. Recommended dosage is 1.5 to 2 grams of EPA plus DHA.
- Vitamin D: Crucial for cognitive functions like serotonin production and dopamine regulation, Vitamin D deficiency is linked to ADHD, especially in children and adolescents. Studies suggest Vitamin D supplementation can improve cognitive function in those with ADHD and deficiency. Checking serum 25(OH)D levels and taking a daily supplement of 5,000 IU of D3 is recommended to optimize levels.
- B Vitamins: These are vital for cognitive function, mood, and stress management, and are involved in synthesizing neurotransmitters. Insufficiencies are common in the ADHD population, particularly for B2, B6, and folate. For individuals with MTHFR gene variations that affect B vitamin conversion, supporting methylation with specific bioactive forms of B vitamins (B2, B6, B9, B12) is important.
- Zinc: Individuals with ADHD are more likely to have lower zinc levels. This mineral is essential for neurotransmitter production and gut health, and inadequate levels may contribute to ADHD symptoms. Zinc levels should be considered in ADHD treatment plans.
- Caffeine: As a stimulant, caffeine influences the brain's dopamine system, similar to ADHD medications. Modest amounts can help improve focus, stimulate the mind, and clear brain fog, offering a "brain boost" for individuals with ADHD.
