Prior to starting the Peak Performance vitamins I would get so tired during the day at work to the point of taking naps in my vehicle at lunch. Since I started taking the vitamins I no longer have that after lunch crash! I feel better overall and can't imagine my life without them. I have lost weight since starting to take them as well along with the super yummy protein shakes. I love every single product I have tried so far and hope to share this information with everyone that I can! My husband even started taking vitamins for the first time in his life and I am not sure he will ever stop after feeling so good!
