Both bovine colostrum and whey come from milk, so they’re easy to confuse — but they serve quite different purposes. Here’s how they compare so you can decide what fits your goals.
Bovine colostrum like SonoHealth’s Cowabunga is a dietary supplement. These statements have not been evaluated by the FDA, and it is not intended to diagnose, treat, cure, or prevent any disease.

What is each one?

Colostrum is the first milk a cow produces in the days after giving birth — naturally rich in antibodies (immunoglobulins), growth factors, and proteins like lactoferrin. Whey is a protein fraction separated from regular milk, typically during cheesemaking, and is concentrated mainly for its protein content.

What do people take them for?

  • Bovine colostrum is usually taken for gut and immune support and general wellness, thanks to its bioactive components.
  • Whey protein is taken mainly to boost daily protein intake for muscle building, recovery, and satiety.
In short: colostrum is about its bioactive compounds; whey is about protein quantity.

Which has more protein?

Whey is the higher-protein choice per serving and is the better pick if your goal is simply to hit a protein target. Colostrum provides some protein but isn’t intended as a primary protein source.

Can I take both?

Many people do — for example, whey for protein and colostrum for gut or immune support — since they serve different roles. Introduce one new supplement at a time so you can tell how each affects you, and see how to take colostrum for timing.

A note on dairy sensitivity

Both are dairy-derived. If you have a milk allergy, neither is automatically safe — colostrum still contains milk proteins. People who are lactose-sensitive tolerate them differently. When in doubt, check with your doctor before starting.
