do vital proteins collagen peptides work?

From a clinical standpoint, yes, they work. But it’s not magic—it’s simply science.
The reason products like Vital Proteins are effective for skin elasticity and joint health is because they use true hydrolyzed collagen peptides. By breaking the collagen down to a very low molecular weight (typically under 5,000 Daltons), the protein becomes highly bioavailable. When consumers take their recommended 10g to 20g daily dose, those specific peptides survive digestion, enter the bloodstream, and effectively stimulate the body’s fibroblasts to produce new collagen.
