What are best supplements to increase focus and concentration?

The options discussed for supporting focus and concentration are alpha-GPC, L-tyrosine, phenylethylamine, and EPA omega-3s.

• Alpha-GPC: 300–600 mg before a focused work bout; the host describes taking it about 10–20 minutes beforehand. He also notes concerns about possible TMAO changes and chronic use, so consider those risks rather than treating it as an everyday default. 1
• L-tyrosine: 500 mg, sometimes combined with 300 mg alpha-GPC and coffee before concentrated work. Effects and tolerance can vary; the episode cautions that dosing needs care. 2 3
• Phenylethylamine: Described as acting in the dopamine pathway and as an occasional option for intense work; the host mentions 500 mg, sometimes added to the other focus supplements. 4
• EPA omega-3s: 1–3 g of EPA daily may support mood, brain function, and cognitive function, which can support focus. 5
• Use supplements after the basics: The recommended order is behavioral tools and nutrition, including good sleep, then supplementation; prescription drugs are a later step and should be medically supervised. 6
