1, 3, 7-trimethylxanthine is one of the most popular smart drugs that most folks don’t even realize that they’re taking. There’s another more common name for this concoction: caffeine. Every time somebody drinks a cup of coffee or tea they are ingesting caffeine and reaping its benefits.
Most experts agree that caffeine has many benefits as long as we consume it in moderation. It’s usually safe to drink coffee, matcha, and black tea a couple of times per day. Caffeine improves alertness and concentration. Furthermore, gymgoers even use it because it boosts energy before training (via ABC).
