Swear by these vitamins. I usually forgo the red pill, which is the caffeine pill for when I may need it, like before the gym at the end of the day. Make sure to take it with food as it's a lot of pills and can make you queasy without. Normally, meds on an empty stomach don't bother me, but these do. The only thing they need to fix is the white pill. There are some batches where this pill falls apart in the bag. I have been taking this for years so this is my only issue and is why I removed one star.
