I've been personally taking GNC's B-Complex for about a year. Until I decided to try writing reviews, I didn't even think about how my life has changed since taking this supplement--it just happened! Before, all I could think about during the day was, "I can't wait to go to sleep." Now, even with work and school and being almost 60 years old, I only sleep at night--no more naps in the middle of the day! Another problem I've had pretty much all of my life is depression. I was prescribed more than one anti-depressant and all I got were nightmares and when I ran out of them, became violently ill (my doctor didn't tell me you can't just stop taking them). Well, I weaned myself off of them as soon as I could. I had taken other B Vitamin supplements and didn't really notice any change, but since I've been taking GNC's B Complex, I do feel much better, both physically and mentally. I would recommend this product to anyone who wishes to be more energetic or lighten their mood (after all, B Vitamins are a must for everyone's health). I've also read in the past that schizophrenia is linked to B Vitamin deficiency.
