Caffeine is a central nervous system stimulant drug used as an aid to stay awake, for mental alertness due to fatigue, as an adjunct with other drugs for pain relief, and as a power and energy accelerate. Caffeine is available alone as a non-prescription drug over the counter medication, in combination with other non-prescription drugs, and in prescription drug combinations for relief of pain and headache.

Like Ephedra, caffeine acts to increase mental alertness while providing additional energy for weight loss and exercise training. Caffeine is more than a stimulant as it goes deep into muscles to provide long lasting power while delaying the onset of muscle fatigue. Also great before working out, caffeine fights fatigue and helps you get ready for your workout.

For dieters feeling sluggish that need just a little something extra to get them through the day, caffeine is the obvious solution. This no-calorie stimulant does the job quickly and effectively and can get the couch potato off the couch and up exercising.

Many products containing caffeine anhydrous contains as much caffeine as one or two cups of coffee. It is recommended to limit the use of caffeine containing medications, foods, or beverages while taking caffeine supplements as excess caffeine intake may cause nervousness, irritability, sleeplessness and occasional rapid heart beat.
