Experience next-level joint care with ZENTRA JointGuard, a science-driven formula combining two clinically studied ingredients—AprèsFlex® (Boswellia serrata extract) and UC-II® (undenatured type II collagen)—to support joint comfort, mobility, and long-term cartilage health.
AprèsFlex®, a next-generation Boswellia serrata extract standardized to AKBA, is designed for fast-acting relief. It helps reduce joint discomfort and stiffness while improving mobility in as little as 5–7 days, and supports a healthy inflammatory response for ongoing joint comfort.
UC-II®, an undenatured type II collagen, works through a unique immune-mediated mechanism to promote joint flexibility and maintain cartilage integrity. At a convenient once-daily dose, it has been clinically shown to improve joint function and outperform traditional glucosamine and chondroitin in key measures.
Together, these ingredients provide a comprehensive, synergistic approach—targeting both the symptoms (pain and stiffness) and the underlying causes (inflammation and cartilage wear) of joint discomfort. The result is enhanced mobility, improved joint function, and long-term support for joint resilience.
