Top Products from Klean Athlete
Klean Creatine
If your sport requires you to go 'all out' for short bursts, creatine can help you reach your strength and power objectives. A vital energy carrier, creatine ensures ATP availability during high-intensity, intermittent bouts of anaerobic or dynamic exercise. And between workouts and on rest days, creatine helps muscles synthesize new protein, facilitating gains in muscle strength, power and size.
Provides support for training performance
KLEAN ESSENTIAL AMINOS +HMB
Athletes have a unique state of mind – driven, goal oriented, and unrelenting. Day, week, and year-in and -out athletes push their bodies to perform at high levels. As athletes age, a greater effort is needed to support anabolic muscle mass. Continuing to perform at peak levels, not only requires proper training, but also demands proper fueling to build and maintain muscles. No matter if you’re in your 30’s or 70’s, Klean Essential Aminos + HMB is designed with a leucine-rich blend of essential amino acids combined with HMB®, vitamin D3 and glutamine to support building lean muscle mass and function for all adult athletes.‡
