Q: I'm 19, and sometimes I feel very tired at work, then at school I feel sleepy.. is there any supplement that could help me be more active..? What do you suggest I do?

A: Don't rely on supps to get you through your day! If you're constantly tired or sleepy, especially at young age like you, there's something wrong with your schedule and/or diet and/or exercise routine. Are you getting AT LEAST 7 hours of good sleep? 8 hours would be best, but at least 7. If not, can you cut something from your routine to get you extra sleep? Are you eating enough? If you're trying to lose weight, you should still eat enough to lose no more than 2 pounds/week max and slower is better. Are you exercising too much? If you spend more than 5 hours in the gym per week and more than 2 hours on cardio per week, you're most likely doing too much and it's starting to affect your everyday life. More is NOT always better. Take a week or two completely off the gym and then come back to a light volume gym program. You can find a bunch of sample programs, both high and low volume, on this page.

Examine all facets of your life to find the cause for your tiredness and fix it, don't rely on pills. There's nothing wrong with an occasional coffee, but that's as far as you should go in trying to keep yourself up when your body is telling you it needs rest.
