If you look at this from a business and market validation perspective, the answer is absolutely yes.
You don’t build a billion-dollar brand and get acquired by Nestlé if your product doesn’t deliver results. In the beauty and supplement space, the repeat purchase rate is the ultimate proof of efficacy. Consumers generally see noticeable improvements in their nail strength and skin hydration within 4 to 8 weeks. Our goal as competing brand owners is to source raw materials that match or exceed that exact level of efficacy.
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.
