  • Maximum Strength Peak ATP 400 delivers a direct supply for optimum cellular energy generation*

  • Supports physical energy and healthy circulation*

  • Made with Adenosine 5'-Triphosphate (ATP)

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 Ultra® Maximum Strength PEAK ATP® features the patented, clinically validated form of adenosine 5’ triph

Customer Ratings & Reviews

Maximum Strength Peak ATP 400 is rated 4.5 out of 5 by 11.
Rated 1 out of 5 by from I Don't Notice Anything Another supplement that I am dubious of. I had high hopes from these reviews. I have taken these awhile and really don't notice anything at all. And, they ain't cheap. I'll finish the bottle, but that's it. Will not buy again.

Rated 5 out of 5 by from Great supplement to start your day I have been taking Swanson's Maximum Strength Peak ATP for about 6 months and have noticed increased energy as I take it with water as soon as I wake up in the morning. I wait for about 1/2 hour before eating anything else to allow it to get into my system. I highly recommend it!

Rated 5 out of 5 by from Brings heart rate up for cardio I've used other brands and drink before, but this is just as effective and it doesn't take up the space some of those powders or drinks do. I found that even when I'm tired and really don't want to be at the gym, this brings my heart rate up even if my body if fighting it. It's easier to keep this in my gym bag and take it about 45 minutes prior to my work out than trying to remember to mix a powder.

Rated 5 out of 5 by from Noticed a Difference I started taking one of these caps prior to my workout and it definitely made a difference in sustaining energy throughout the workout.

Rated 5 out of 5 by from HIGHER ENERGY I'm glad Swanson came out with this 400 mg. ATP capsule. I had been taking their 125 mg. ATP for as long as it has been available. I like to use ATP regularly as an natural energy source for my cells. Works for me.

Rated 5 out of 5 by from First Time Purchase I tried Peak ATP for the first time and have been happy with the product. It is the cheapest here on Swanson out of any online marketplaces and arrived in a timely fashion.

Rated 4 out of 5 by from Max Strength Peak ATP 500 I'm taking this for improved energy as I'm often very fatigued. Since I've been taking it I've still been fatigued but less so. I'm not sure if it's the ATP or just a fluke but I'll keep taking it for a while at least and see what happens. I'd love to have more energy but any increase is appreciated. Note this has not had any negative side effects so I like that, not jittery or hyper, not like a stimulant just a natural feeling extra bit of energy. I only take one pill a day so maybe I'll increase my dose and see what happens. I ramble.
