American Beast combines bison liver (which is rich in Vitamin A, B12 and folate) with bison heart (a natural source of CoQ10, iron and taurine). Together, they support strength and endurance by fueling energy production, oxygen delivery and optimal cardiovascular function.
You push your limits in the gym. American Beasts helps you maximize your gains by fueling your body with the essential nutrients needed for muscle growth, endurance and resilience.
