ABOUT ARMA

Endurance and action sports require peak performance from athlete’s bodies and the proper nutrition before, during, and after these activities. Arma recognized a void in the marketplace and created a complete line of nutritional supplements formulated specially to help athletes and enthusiasts of all levels realize their maximum potential. They utilize not only the best ingredient combinations but clinically proven dosages. Arma nutritional supplements have undoubtedly achieved best-in-class formulations.

Arma's products were developed and tested in real-world conditions by an all-star team of athlete owners that includes Jeremy McGrath, the winningest rider in Supercross history; Chad Reed, two-time Supercross champion, who holds the record for the most career supercross starts; and Nick Wey, a former factory rider with 191 Supercross main event starts to his credit, who now trains and coaches several of the sport’s elite.
