    Comments about Guarana Energizer™, 900 mg 200 tablets: Source Naturals:

    My 19 year old son attending a Service Academy. The hours, activities, and study requirements are very intense. Wake up at dawn, class and active all day, study until midnight, and sometimes a three hour watch between 1:00 AM to 3:00 AM.
    Fresh brewed coffee had positive effects, but would tend to peak then drop. Too much coffee made it hard to wind down or for example take a 1 hour nap in the afternoon if the opportunity arises.
    This product offers a great amount of energy that appears to be constant for around 4 to 5 hours. Coffee "Jitters" went away. Coffee has been dropped completely because this fits this specific Spartan lifestyle. For studying engineering, this product appears to be vastly superior over coffee or any other over-the-counter caffinee products. No side-effects have been noticed. Grades actually improved in direct proportion to the switch from coffee to Guarana. Teachers commented on improved alertness during afternoon class.
    Note: Son does not ever drink cola's (soda) or eat any kind of starch junk food. Very light sugar such as breakfast sweet-roll, never uses table sugar. Swims miles each week, intensive exercise, and runs many miles a week.
    This product is taken with the LEF Mix, Yohimbe-Plus. This with high protein diet has resulted in the optimum results for the lifestyle.
