Probiotic bacteria As you might expect, BDNF is produced primarily in the brain, but it’s made in a long list of other places, including the muscles, heart, lungs, gut, and a few more. Unfortunately, BDNF production decreases as we age, with important implications for brain health. The upshot: Fewer neurons (and the connections between them), making learning and memory formation harder.
lack of BDNF or when something prevents it from working properly? Along with impaired learning, decreased levels have been associated with a variety of neurological/mental conditions
