When you eat less, every nutrient has to work harder.
GLP-1 medications are designed to reduce appetite and support weight loss. Eating less can also mean getting fewer nutrients. Here is how WonderCow Colostrum can help:
Your gut depends on nutrients
The gut lining, intestinal barrier, and much of your digestive immune system rely on proper nutrition to function at their best.
This is where colostrum can help
Whole bovine colostrum is naturally rich in bioactive compounds that help nourish and support gut health.
Nutritional support throughout your weight loss journey
As you work toward your weight management goals, colostrum helps provide targeted nutritional support for overall digestive and immune wellness.
What’s inside
400+ bioactive nutrients
Whole colostrum. Nothing stripped.
Lactoferrin
Supports gut barrier integrity and iron absorption efficiency.
Proline-Rich Polypeptides (PRPs)
Bioactive peptides that help modulate immune response.
Growth Factors (IGF-1, TGF-β)
Support cellular repair and regeneration of the gut lining. Important during periods of lower nutrient intake.
MFGM (Milk Fat Globule Membrane)
A unique phospholipid-rich membrane carried in the fat fraction. We keep the fat, so you get the MFGM.

What people say
She made it through the entire winter without a sick day. I literally cried. This is the first time in 3 years that's happened.
No more stomach aches. No more constant colds. And honestly? My nails are stronger and my skin is glowing. Did not expect that.
I was skeptical. Very skeptical. One month later — better sleep, better mood, and my kid hasn't missed a day of school. We're not stopping.
Your gut does better when it has what it needs.
