Methylene Blue, a synthetic dye turned drug, is gaining attention as a potent nootropic that improves mitochondrial efficiency, acts as an antioxidant, and modulates neurotransmitter systems. Clinical and pre‑clinical studies show low‑dose supplementation enhances memory, mood, and offers neuroprotective benefits in models of Alzheimer’s, Parkinson’s, and depression. The compound works by donating electrons to the mitochondrial electron transport chain and inhibiting monoamine oxidase, thereby increasing ATP production and serotonin levels. Safe dosing ranges from 0.5 to 4 mg kg⁻¹, but higher amounts can cause serotonin syndrome and other side effects.

Acetyl‑L‑Carnitine (ALCAR) is a bioavailable form of L‑carnitine that readily crosses the blood‑brain barrier, delivering energy‑boosting fatty acids to mitochondria and supporting acetylcholine synthesis. Clinical studies show ALCAR can improve memory, mood, and fatigue, and it performs comparably to antidepressants...

Sulforaphane, a sulfur‑rich isothiocyanate found chiefly in broccoli, acts as a potent antioxidant and anti‑inflammatory agent by activating the Nrf2 pathway. Clinical trials have documented up to 34% behavioral improvement in autism spectrum disorder and neuroprotective effects in Alzheimer’s mouse...
