Altovis is designed to provide a boost to energy in two parts. The most immediate increase in energy is provided by caffeine from green tea, which enhances our perception of physical and mental energy by stimulating the central nervous system. This stimulation results in the fairly immediate effects of increased wakefulness and alertness, a decreased sense of fatigue and elevation of mood. There is often an improvement in physical performance as well. More fundamental and more subtle are the concepts of "vital energy" (a Traditional Chinese Medicine theory) and of ingredients considered to be "adaptogenic". Adaptogens support and strengthen the body to enable it to better cope with the negative effects of stress. Adaptogens are a unique group of herbal ingredients used to support the health of your adrenal system. They help strengthen the bodys response to stress and enhance its ability to cope and fight fatigue slowly and gently, without jolts or crashes. Theyre called adaptogens because of their unique ability to adapt their function according to your bodys specific needs. Though the effects may initially be subtle and take time to make themselves felt, theyre real and undeniable.*
