Adults with ADHD show consistent deficits in iron (ferritin <30 ng/mL in 84%), vitamin D (6.5 ng/mL lower), zinc, and magnesium. Supplementing these deficiencies produces measurable symptom improvements — particularly ferritin optimization (target >50 ng/mL), vitamin D (4000 IU/day), and zinc (15–30mg). L-tyrosine shows no benefit and develops tolerance. Screen for deficiencies before supplementing; prioritize iron and vitamin D testing.

A seven-compound nutraceutical protocol (Omega-3 EPA ≥60%, Saffron 30mg, SAM-e, L-Methylfolate, Zinc, Curcumin+piperine, Magnesium glycinate) has demonstrated adjunctive efficacy for anxiety and depression across multiple RCTs and meta-analyses. Omega-3 EPA (≥1g/day) reduces depressive symptoms with effect size d≈0.61 in meta-analysis; Saffron 30mg/day matches fluoxetine 20mg in multiple head-to-head RCTs (n=40–60 per study). SAM-e (800–1600mg) and L-Methylfolate (15mg) show strong evidence specifically as SSRI augmentation. This protocol is intended as an adjunct to, not replacement for, standard psychiatric care.

Natural interventions for attention and focus show modest but real effects — especially for non-diagnosed 'brain fog' and subclinical attention difficulties. For clinically diagnosed ADHD, medication (stimulants or atomoxetine) remains the gold standard with the strongest evidence; natural compounds are best used as adjuncts or in cases where medication is declined. The strongest-evidenced natural interventions are: Magnesium (especially in those who are deficient), L-Theanine + low-dose caffeine (best acute focus combo), Omega-3 fatty acids EPA-dominant (particularly in children), and NAC for impulsivity. Effect sizes are consistently smaller than pharmaceutical interventions.
