“I am a linguist in the military and have only been taking NITROvit for just under a week. I have never taken nootropics before except for a caffeine/L-Theanine stack – which was great – but I felt like I wanted a bit more focus. I am the type of person who researches everything, even more when it is something going into my body. All my research led me to a handful of positively reviewed ingredients and eventually led me to NITROvit. I was a bit skeptical, but I knew the ingredients in the formula were legit by themselves so I gave it a go and bought a months worth. I am SO glad I did.
