Fast-Acting
GNC TriFlex
Overview
GNC TriFlex Fast-Acting combines several ingredients known for joint support. Glucosamine and chondroitin are included at clinically relevant doses, while Boswellia and turmeric provide additional anti-inflammatory support. However, the MSM dose is low. The product claims to improve joint comfort and stiffness in as few as 5 days, but individual results may vary. The product may help to slow down disease progression of joint pain, rather than reverse it.
