Colostrum, Cordyceps, and Collagen: What the Science Actually Says

Colostrum, Cordyceps, and Collagen: What the Science Actually Says

At Cerus Performance, we don’t chase trends—we chase results. That’s why Renew is built around three powerhouse ingredients with serious backing: colostrum, cordyceps, and collagen.

 

Colostrum is rich in growth factors, immune-supporting antibodies, and nutrients that can help repair the gut lining and support recovery—especially in high-stress training environments. Studies show it may even reduce the risk of upper respiratory infections in endurance athletes.


Cordyceps is the secret weapon of ancient Chinese medicine now embraced by modern athletes. It’s been shown to improve oxygen utilization and increase VO2 max, helping you go longer without gassing out.


Collagen supports joints, tendons, skin, and gut health. Athletes put stress on connective tissues daily—collagen gives your body the raw materials to repair and rebuild. Bonus: it may also aid recovery by reducing soreness.


Together, these three ingredients don’t just support your body—they prepare it to perform, adapt, and recover on repeat.


Bottom line? This trio works smarter and harder. No fluff. No filler. Just real results.
