What is BDNF? Why is it important to my brain health?

Brain-Derived Neurotrophic Factor (BDNF) is a key neuroprotein involved in overall brain health.

There have been over 8,300 scientific researches published on BDNF since 2014, studying its importance on brain health. It plays a vital role in the development, maintenance, connection and protection of brain neurons.

Low BDNF has been associated with a variety of brain-related health concerns, while higher BDNF = Better Brain Function.

JostArriba delivers CognatiQ, a patented coffee fruit extract that has been clinically proven to boost BDNF, increase brain connectivity, and improve daily, cognitive performance.
