Now, of course that's still entirely possible, but I think studies such as these increase our confidence that things like L-carnitine can be used perhaps in concert with things like omega 3 supplementation, diets that are biased towards increasing more tryptophan and therefore more serotonin, obviously avoiding things like alcohol and as it appears from the study I just described, reducing one's intake or not consuming any caffeinated alcoholic beverages seems like it would be a good idea if your goal is to reduce aggressiveness, to think about the hormone context and whether or not you tend to have higher testosterone, an estrogen or lower testosterone, an estrogen, maybe even think about the work environment, whether or not you are existing in a particularly competitive work environment and even day life, time of year and whether or not you're getting sufficient sunlight, whether or not you're avoiding light in the evening and so on.
