What supplements help adhd and how

Omega-3s, acetyl-L-carnitine, L-tyrosine, and phenylethylamine (PEA) are discussed as possible supports for focus or ADHD-related symptoms, but their evidence and cautions differ.

• Omega-3s (especially EPA): About 1–3 g of EPA daily is described as potentially supporting mood and cognitive function, which can help support the brain networks involved in focus; it is not presented as a direct ADHD treatment. 1
• Acetyl-L-carnitine: In a study of children with ADHD, supplementation was associated with improved symptoms, including reduced attentional problems and aggression. The study used 100 mg/kg per day, capped at 4 g, taken twice daily after meals. 2 The discussion also describes reduced impulsivity and improved self-regulation as outcomes of the study. 3
• L-tyrosine: As a dopamine precursor, it may increase dopamine and support focus, but dosing varies widely and it can cause jitteriness, euphoria, or excessive alertness that makes focusing harder. A cited range is 100–1,200 mg; extra caution is advised with psychiatric or mood disorders. 4
• Phenylethylamine (PEA): PEA can increase dopamine transmission and is used by some as a focus aid, but the discussion frames it as a dopamine-modulating supplement rather than an established ADHD treatment. 5

These supplements affect people differently; discuss them with a healthcare professional, particularly if you have a mood or psychiatric condition. 6
