Why You Can’t Focus: Dopamine, BDNF & Brain Peptides Explained

ocus isn’t a willpower problem — it’s a brain biology problem.

In this video, I break down how focus actually works in the brain and why so many people struggle with attention, motivation, and mental clarity in midlife and beyond. We’ll connect the dots between dopamine, hormones, BDNF (brain-derived neurotrophic factor), lifestyle habits, supplements, and emerging research on brain peptides — all from a science-based, educational perspective.

We cover:
• How dopamine drives motivation and sustained attention
• Why hormones like estrogen, progesterone, and testosterone directly affect focus
• What BDNF is and why it’s essential for learning, memory, and neuroplasticity
• Natural ways to boost dopamine and BDNF through exercise, cold exposure, sleep, and nutrition
• Supplements commonly used to support focus and cognitive resilience, including L-theanine, teacrine, magnesium L-threonate, and methylene blue
• An educational overview of brain peptides often discussed in research settings, including Semax, P21, SS-31, Noopept, and Dihexa — with important safety considerations

This video is designed to help you understand why your brain behaves the way it does and how to support focus by working with your biology instead of fighting it.
