The best supplements for your muscles


Creator Jason Arntz

Jason has been involved in the sports supplement industry for over 25 years. As a top IFBB professional athlete (4x Mr. Olympia 212 competitor and 3x NPC National Champion), trainer, nutritionist and salesman I know firsthand the most important ingredients and supplements that will help you reach your goals. 

After years of seeing products that do not create any type of effect, that are copy cats and serve no purpose I took the initiative and formulated my own product line, I-Prevail Supplements™. Every product I have designed has a purpose and a signature to it that makes it unique from anything else on the market. 

I-Prevail™, we may be new to the game but we are here to stay and set a new standard

At I-Prevail™ our team has spent years studying sports nutrition and performance. We firmly believe we have created a new Golden Standard of formulated supplements developed with premium ingredients and proven formulas that are backed by science, research, clinical studies and applied use. 

Delivering QUALITY.

I-Prevail™ supplements are US manufactured in state-of-the-art, FDA-inspected facilities. Our manufacturers are Current Good Manufacturing Practices (cGMP) compliant. They are approved by leading certifying bodies, using approved Standard Operating Procedures (SOPs), which are implemented by our Quality Control team.

We spend the time to test each step of the process in developing our products. Each raw ingredient is tested to ensure it meets our high standards and specifications. All finished goods are subjected to additional in-house and 3rd party lab testing. This ensures you, our valued customers, get only our very best. We are developing products that work together and are designed to stack perfectly. This will maximize your time, energy, pumps and increase your overall performance.


 It is no secret that the fitness culture has grown immensely across the globe and those who refuse to change will only be left behind. We at I-Prevail™ want nothing but the best for our customers. This is why we offer our years of education and knowledge sculpted together to form our top of the line products. These are the supplements that work.
