From the Manufacturer:
Peak energy contains Adrenal Triphosphate (ATP), a natural compound that is responsible for creating and transferring energy at the cellular level. The body has millions of chemical reactions that occur every second and most of them require energy created by ATP. By the time people reach 70 years old, ATP pools in the blood cells decline by as much as 50%. These declining APT levels can lead to a loss of wellness and vitality, reduced nutrient aborption, slower cellular and tissue regeneration, memory loss, muscle loss, and poor circulation.
