What the Evidence Says

AI-generated · Qwen 3.6 · methodology

This formula combines collagen and eggshell membrane, which have moderate evidence for supporting joint structure. Turmeric and magnesium are included for their researched roles in managing inflammation and muscle function. Vitamin C provides necessary support for collagen synthesis, though overall evidence coverage for this specific blend remains limited.
