There's one very simple "nootropic" that I've discovered many years ago and have been doing most days of the week. Buying a cup of coffee and taking a walk in nature. It makes me feel better than just coffee or just walking in nature. Another benefit is that in the days I can do this, I have something to look forward to since waking up.
Good simple nootropic, but I like the cup of coffee even better with a 200mg capsule of a high quality L-Theanine to give a zen-like calm to the stimulation of the caffeine. Underrated as heck IMHO.
Any brands that you would consider high quality? I'm currently using Nutricost, but only because it was the cheapest, and I didn't know they were allowed to fiddle with quality on these things.
