Many supplements claim to support physical energy and circulation, but if you really want to get your blood pumping, Swanson Maximum Strength PEAK ATP(R) 400 works like no other. Maximum Strength PEAK ATP 400 is a clinically researched, patented form of adenosine 5'-triphosphate (ATP), the energy currency of life. While other supplements work to support ATP in the body, PEAK ATP provides a direct supply for optimum cellular energy generation. ATP is the molecule that stores the energy for just about every physical function. It is constantly being used and regenerated within our cells. Every day your body turns over as much ATP as you weigh! PEAK ATP ensures that your cells are never in short supply of this basic energy currency, and research shows this extra boost results in better physical performance and quicker recovery after exertion. PEAK ATP works through three distinct mechanisms to promote physical performance, reduce fatigue and support healthy blood flow. ATP increases muscular excitability, resulting in significant gains in strength and power. ATP stimulates blood flow, resulting in better delivery of oxygen and nutrients to the muscles (including the heart). ATP is involved in anabolic signaling, thus promoting lean body mass and healthy muscle structure. ATP continues to deliver benefits after exercise as emerging research suggests it may promote both mental sharpness and muscle recovery post-workout. Our Maximum Strength 400 mg capsules give you the power to fight fatigue, promote healthy circulation and optimize your physical performance quickly, safely and easily. You'll notice the difference in just one week, and according to the research, things will just keep getting better from there! For athletes looking for a safe source of supplemental ATP to enhance their strength and stamina, Swanson Maximum Strength PEAK ATP(R) features the patented, clinically researched form of adenosine 5' triphosphate.
