It's not the bloating. It's the lining.
First it was just one food that didn't sit right. Then a few more. Then the colds that never really stop, the stomach aches before school, the skin that flares for no reason.
You're not imagining it. Your kid isn't getting more sensitive. Something underneath is changing, and that something is the gut lining.
80%of the immune system lives in the gut
Colostrum is the original gut repair
WonderCow colostrum is whole. Never homogenized, never fractionated, no fillers spiking the numbers. Sourced from US family farms. Our cows eat grass.
One supplement for the whole family
Same whole colostrum in everyone's morning, stir it into a smoothie, milk, or coffee.
Gut Health
Repairs the lining itself, not the symptoms on top of it.
Restful Sleep
When digestion settles, sleep usually follows. For your kid and for you.
Skin Health
A lot of flare-ups start in the gut. When the lining heals, skin often clears up on its own.
Brain & Mood
A calmer gut means fewer meltdowns, better focus at school, and more patience for you too.
Made by a family. For a family.
Since before you were born.
Rob is a 7th-generation dairy farmer. Seven generations on the same land in Central California, going back to his grandfather and uncle in the 1960s.
When Rob's own daughter started getting sick all the time, antibiotics had worn down her gut and her immunity. He didn't look for a new supplement. He looked at the farm he grew up on. Colostrum changed her health, her energy, her mood, and that's the whole reason WonderCow exists.
You can ask us where every batch comes from. We can tell you. We've been raising calves on colostrum for over a hundred years.

Don't take it from us, we're biased (it's our farm)
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.
