I have always consider myself healthy. I exercise daily, and maintain a healthy weight. The only thing I'm guilty of is not eating a well balanced diet. I don't over eat on junk food, but I will admit that I don't get a good share of vegetables, and fruits. This is where Centrum helps out. If you're not getting your daily recommendation of vitamins, you may need to opt for this supplement. Centrum for Men is tailored specifically for men (they also feature a female version, as well as supplements for those of you over the age of 50). I have been taking this multi-vitamin for almost a year now, and I can definitely tell a difference in the way I feel, and the energy I have. Also my check-ups have improved when visiting my doctor. Centrum comes in many forms, (chewables, gummis, capsules, pills, etc), to fit your personal tastes. If there is one supplement you should take, Centrum is the one.
