They demand more than muscle building in their protein choices but also want **overall wellness and multifunctional nutrition**. To win in today's competitive market, you need a smarter formulation. A solution that protects your margins, while delivering targeted health benefits your customers crave.  Whey protein is the gold standard for muscle building, but it lacks hydroxyproline, the key amino acid in collagen associated with connective tissue support and recovery. By blending Whey and Collagen, you bypass volatile whey costs and unlock formulation flexibility. This supplementation allows you to stabilize your costs and supply, while enhancing value with added benefits.  [Connect with our experts today](https://www.darlingii.com/rousselot/contact) ### Benefits of Whey + Collagen blends: ![Untitled design (26)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(26).png?width=100&height=100&name=Untitled%20design%20(26).png "Untitled design (26)") Opportunities for cost optimization ![Untitled design (27)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(27).png?width=100&height=100&name=Untitled%20design%20(27).png "Untitled design (27)") Product differentiation ![Untitled design (29)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(29).png?width=100&height=100&name=Untitled%20design%20(29).png "Untitled design (29)") Formulation flexibility ![Untitled design (25)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(25).png?width=100&height=100&name=Untitled%20design%20(25).png "Untitled design (25)") Complete protein solution + collagen-specific bioactivity ![Untitled design (28)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(28).png?width=100&height=100&name=Untitled%20design%20(28).png "Untitled design (28)") Support beyond muscle (recovery, connective tissue, healthy living) ### Choose your upgrade: Tailored functional benefits ![Untitled design (32)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(32).png?width=700&height=150&name=Untitled%20design%20(32).png "Untitled design (32)") ![1-3](https://resources.rousselot.com/hubfs/1-3.png "1-3") [Learn more](https://www.peptan.com/) ![Untitled design (33)](https://resources.rousselot.com/hs-fs/hubfs/Untitled%20design%20(33).png?width=700&height=150&name=Untitled%20design%20(33).png "Untitled design (33)") ![Peptan (4)](https://resources.rousselot.com/hubfs/Peptan%20(4).png "Peptan (4)") [Learn more](https://nextida.rousselot.com/nextida-gc?hsLang=en) ### Application benefits ![Whey & Collagen Website Applications](https://8886786.fs1.hubspotusercontent-na1.net/hub/8886786/hubfs/Whey%20&%20Collagen%20Website%20(4).png?width=1200&length=1200&name=Whey%20&%20Collagen%20Website%20(4).png) Application versatility (powders, bars, RTD, etc.) ![Whey in Liquid ](https://8886786.fs1.hubspotusercontent-na1.net/hub/8886786/hubfs/2-4.png?width=1200&length=1200&name=2-4.png) Improved solubility ![3-1](https://8886786.fs1.hubspotusercontent-na1.net/hub/8886786/hubfs/3-1.png?width=1200&length=1200&name=3-1.png) Improved texture and palatability #### Ready to upgrade your protein portfolio?
