Hi, I keep searching about the method how to increase my serotonin level inside my brain. I keep reading about food that contain rich serotonin, for example banana. But end up it's pointless because serotonin in banana cannot be blablabla transfer to the brain due to some "political/complex" issue. After reading bunch of articles, the conclusion is, you need to eat carbohydrate alone without mix it with protein. I also found few provider that selling pills to boost your serotonin. Just go to AMAZON and search for this keyword "5-htp". Anyone know what's the best brand for boosting serotonin inside my brain? It's good?
