Core Colostrum: Now in Glass Jars. Shop Now →

The short list: gut lining repair, immune support, lean muscle recovery, and skin health*. The longer answer is that colostrum works because of what's inside it. Immunoglobulins fight off threats before they take hold. Growth factors like IGF-1 help repair tissue and support muscle. Lactoferrin keeps the gut barrier strong. It's not a one-trick supplement. It's the whole toolkit.*

Colostrum is incredibly versatile. You can mix it into your morning smoothie, stir it into water or juice, or blend it into coffee. One scoop daily is all you need. For best results, take it consistently and on an empty stomach when possible, which helps maximize absorption. Prefer something grab-and-go? Try our colostrum gummies.

Most people notice gut and immune changes within 2–4 weeks of daily use. Like most real-food supplements, consistency is the key variable.*

Grass-fed, pasture-raised cows in the U.S. Collected within the first 6 hours after calving, only after the calf has received its full share.

One ingredient. Five reasons it works.

Colostrum contains lactoferrin and growth factors that help repair and reinforce the gut barrier. Think of it as patching the leaks before anything else gets in.*

Rich in immunoglobulins (IgG, IgA, IgM), the same antibodies your immune system relies on to recognize and respond to threats.*

IGF-1 and other anabolic growth factors support muscle repair and lean tissue development. Used by athletes for decades for good reason.*

The growth factors in colostrum support cellular regeneration, which means better skin, stronger hair, and healthier nails, starting at the source.*

Emerging research links colostrum to potentially improve insulin sensitivity and blood sugar regulation.

Nature's first food, not a formula.

Sourced from grass-fed, pasture-raised cows, we start with the most bioactive ingredient on earth and do as little as possible to it. No fillers, no shortcuts. Just colostrum, exactly as nature intended.

How Our Colostrum Is Made

We source our colostrum from grass-fed, pasture-raised cows in the U.S. Collected within the first 6 hours after calving, when bioactive concentrations are highest, and only after the calf has received its full share. No shortcuts, no factory farms. The calves eat first. Always.


Our colostrum is minimally processed at low-temperatures to preserve the bioactive compounds nad nutrients. Many competitors use high-heat processing, destroying immunoglobulins and other growth factors, charging you a premium for a glorified milk powder.
