Just like some people are able to drop massive amounts of weight and never gain it back, you can drop your chronic depression, anxiety and poor cognition and never have it consume you again.

One way to do this is by increasing brain-derived neurotrophic factor, also known as BDNF.

BDNF is a naturally-occurring protein in the brain that improves brain function and lowers your risk of mental disease.

BDNF protects and repairs your brain cells, increases the growth of new brain cells, and improves learning, memory and mood. In fact, many researchers consider it a natural antidepressant (12-17, 66).

Research suggests that if you struggle with mental illness or poor brain function, you likely have reduced levels of BDNF. But luckily, there are ways to boost it. And by doing so, you can reverse depression and protect yourself from Alzheimer’s disease (46-50, 31, 64-65, 67).

After suffering two concussions, living in a moldy house, and falling into a deep depression in 2010, I started searching far and wide for ways to boost BDNF and heal my damaged brain.

Below are 31 ways that significantly helped me, and they likely will help you too.
