Jeremy McGrath remains the undisputed King of Supercross, with 72 career premier-class AMA Supercross wins (that’s 22 more than second place, a very fast fella by the name of James Stewart). His 7 AMA Supercross Championships remain the standard to beat in the sport. And while he’s retired from pro motocross and supercross, he remains active in off-road truck and stock car racing, even recently taking a turn behind the wheel of a monster truck. Fitness and recovery are still vital issues to him, especially as he nears his upcoming 50th birthday. And that’s why he still uses ARMA products daily.

McGrath, in fact, helps with product development at ARMA, ensuring that the company’s supplements are up to snuff and that they tick all the boxes necessary for competition at the highest level of motocross/supercross and high-intensity athletic pursuits in general.

One of the things that ARMA focuses on is bioavailability—essentially, ensuring that your body can actually absorb and use all of the good stuff in the supplements you’re taking. Without the proper chemistry, it’s possible for a good portion of your supplements to simply pass right through your body, wasting money and hurting both your performance and your recovery. ARMA makes sure the amounts included in their supplements can be absorbed, and knows which ingredients can actually boost your body’s ability to absorb and utilize those ingredients.

While ARMA is popular among top pros in the sport—alongside MC, it’s championed by the likes of Chad Reed, Nick Wey, and Adam Cianciarulo, among others—it’s also popular with non-professional athletes who simply want to stay on top of their game. ARMA is made for all athletes, in all sports, participating at every level.
