Naturally Balanced & in Peak Form - Immune Tree's Colostrum

by Carly Neubert, BA, NC on May 20, 2025

If you’ve been on the nutrition and supplement sides of social media, you may have seen a boost in talk about colostrum. Doctors and researchers around the world are curious about the benefits of this nutrient packed ‘food’. It’s no secret that colostrum is crucial to a newborn, but what might it do for you as you continue in your development? Colostrum can support your gut, your immune system, and has many potential benefits that we’ll explore in this blog post. Immune Tree offers colostrum in both a powder and capsule form, making it easily accessible in whichever form you prefer. First thing first, let’s learn a bit more about colostrum and even more specifically, bovine colostrum.

A Crash Course on Colostrum

Colostrum is the pre-milk fluid produced during the first few hours after birth. This is a 72-hour window for human mothers and 0-6 hours for Bovine/Cow Mothers. This fluid provides immune and growth factors that boost the health and vitality of a newborn. Colostrum is so rich in nutrients, you may have heard it regarded as ‘liquid gold’. Keep in mind, this is a pre-milk fluid produced by mammalian mothers prior to the birth of their off-spring, and thus, it is not milk. There is almost no lactose found in Colostrum allowing those who are lactose intolerant to be able to take high quality Colostrum without experiencing discomfort. We’ve written about colostrum before on our blog, you can check that out here for a refresher. In this blog, I’ll be highlighting Immune Tree’s colostrum supplements, as they are a standout in the market for a number of reasons.

6-hour Colostrum Certified

A crowning feature of Immune Tree’s Colostrum is that it is 6-hour colostrum certified. The 6 hour window for Bovine/Cow mothers is crucial. This is what ensures you’re getting true colostrum, rather than ‘transitional milk’ which is what you find in many supplements claiming to be colostrum. Transition milk is exactly what the name sounds like, it is the milk that comes between colostrum and whole milk. While transition milk has more benefits than whole milk, there is a substantial decrease in the nutritional benefits that are provided in colostrum.

Immune Tree Highlights

Immune Tree offers natural colostrum supplements that are organic, GMO free, hormone free, and gluten free. Immune Tree’s colostrum supplements were created by Dr. Anthony Kleinsmith who holds a Nutritional Science PhD with a special focus on colostrum. Kleinsmith is often regarded as a leading authority on colostrum due to his extensive study of this supplement. Immune Tree confidently notes that their colostrum is independently tested and certified as 6-hour colostrum. Packed with 97 immune factors and 87 known growth factors, Immune Tree’s bovine colostrum is marked as being up to 1000x more potent than a human mother’s colostrum, and not species specific. This means that the benefits of bovine colostrum do not only benefit other bovine, but the nutrients provided have also shown impact on humans and some studies have even used bovine colostrum in general veterinary practices.

Calf Served First

Of course, we can’t forget the main purpose of colostrum. Bodies produce colostrum to support a newborn. The nutrients, growth factors, antibodies and more that colostrum offers are crucial to the mortality of the newborn. This is why Immune Tree has a calf served first collection policy. The calf always receives what it needs from the mother, and the excess colostrum is then used to bring you those same benefits.

Immunity & Gut Health

I’ve thrown out a lot of official words in this blog when it comes to the benefits of colostrum, so let’s break those down a bit further. Colostrum contains more protein than mature milk, and the protein contained in colostrum is made up primarily of immunoglobulins. Immunoglobulins are antibodies that boost your immune system as a whole. Studies of colostrum have seen Immunoglobulins make a difference with leaky gut, IBS, and even respiratory tract infections.

Growth Factors at Work

The growth factors contained in colostrum are primarily responsible for the ‘anti-aging’ properties of colostrum. These fight against the dip in energy level, loss of skin elasticity and muscle tone that comes with aging. Growth factors affect the growth of cells. Health on a cellular level expands to systems and our body as a whole, which is why they are so important. The specific growth factors in colostrum can be seen impacting hormone synthesis, gut growth and repair, wound repair, vascular system health, and overall immune health as well.
