A natural product energy drink is provided, which synergistically aids in (1) function of the heart, (2) energy production, such as in muscles, and/or (3) enhances removal of toxic free radicals. For example, the natural product energy drink enhances function of the heart, by the use of CoQ10 enables the body to produce more energy through enhanced efficiency of the Krebs cycle, such as by use of L-carnitine and aids in the removal of waste and/or toxins produced in the body, such as by providing anti-oxidants. Hence, the energy drink synergistically optimizes the heart, muscles, and toxin removal at the same time, which allows the user to prolong duration of exercise, increase intensity of exercise, and recover faster. The natural product, which provides nutrients, is an energy drink that optionally contains no caffeine or sugar while retaining efficacy.
