  • Provides optimal cellular energy generation



  • Made with adenosine 5'-triphosphate (ATP), which stores energy for every physical function



  • Supports physical energy and healthy circulation


Many supplements claim to support physical energy and circulation, but if you really want to get your blood pumping, Maximum Strength PEAK ATP® 400 works like no other. Maximum Strength PEAK ATP 400 is a clinically validated, 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.

ATP can be synthesized intracellularly from the precursors adenosine diphosphate (ADP) and adenosine monophosphate (AMP) as well as phosphate group donors with the aid of an enzyme known as ATP synthase. During hydrolysis, the energy stored in ATP’s phosphate bonds is released as free energy, which is harnessed by the cell to fuel basic cellular functions. The ADP that remains after ATP hydrolysis is subsequently recycled back into ATP in a continuous process. Through this constant regeneration, the typical human body turns over an amount of ATP roughly equal to its own weight each day. Intracellular ATP levels are tightly controlled, ensuring an uninterrupted energy supply to power all essential cellular functions.

PEAK ATP works through three distinct mechanisms to promote physical performance, reduce fatigue and support healthy blood flow.

  1. ATP increases muscular excitability, resulting in significant gains in strength and power.
  2. ATP stimulates blood flow, resulting in better delivery of oxygen and nutrients to the muscles (including the heart).
  3. ATP is involved in anabolic signaling, thus promoting lean body mass and healthy muscle structure.

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® features the patented, clinically validated form of adenosine 5’ triphosphate.

Rated 5 out of 5 by from Works for me! Of all the supplements to increase energy I have tried ATP has worked the best!

Rated 5 out of 5 by from Peak ATP & Cordyceps before a work out I have been using Peak ATP and Cordyceps to improve my workouts for a few years. They are a great combination. I take one of each about 1 hour prior to going to the gym or on a bike ride. On a long bike ride of 3+ hours I take another set at the turn around point along with a snack. This really helps complete a demanding workout.

Rated 5 out of 5 by from One of my favorite supplements I takethis before every workout to boost my stamina and energy.

Rated 3 out of 5 by from Not sure if it works. I have a degree in exercise and nutrition and am an avid gym goer. I added this to an established training regiment. I have not seen any notable change in energy levels or endurance. I trust Swanson's quality, but as much of the research suggests, I'm not convinced an ATP supplement is effective. I will continue the 8 weeks worth I purchased, and will update if I have any changes to add.
