I have been taking this vitamin supplement for over 1 year. It has drastically improved my sleep, and have noticed an overall increase in energy, which I definitely notice when I forget to take it. I also noticed an improvement in my fitness workouts with endurance, stamina, and recovery.

I'm 65 years old. Four years ago I was introduced to E18 supplements. Soon after I start taking it I notice that my sleep was improved and that had a positive change on my daily activities by gaining more energy. Also I noticed the E18 improved my digestion. I would highly recommend it.
