The colostrum boom has created more marketing than integrity. Behind glossy labels and buzzwords, many brands destroy the very bioactives that make colostrum powerful.

Take the Colostrum Quiz

Find out if colostrum is right for you — and whether your current supply is truly uncut.

What most colostrum brands don't want you to know

High heat processing & instantizing (denaturing the proteins)

Most colostrum powders are exposed to high heat, pressure, and aggressive instantizing steps designed to make them mix easily — but these steps come with a steep cost: they denature the very proteins and bioactives that make colostrum effective.

Colostrum contains fragile immunoglobulins, peptides, enzymes, and growth factors that have specific temperature thresholds. Once those thresholds are exceeded, the proteins unfold, break apart, and lose biological activity

What happens during high heat & instantizing:

  • Immunoglobulins (IgG, IgA) lose structure → reduced binding ability
  • Lactoferrin, PRPs, and enzymes become inactive
  • Growth factors degrade rapidly
  • Sensitive proteins oxidize under heat + pressure
  • The final product mixes easily… but is basically milk, not colostrum

Colostrum isn't just milk — it's a collection of delicate bioactive molecules.

If you denature them, you erase the benefits.

Defatting processes (skimmed, loss of nutrients, sacrificing the "whole food")

Many engineered colostrum powders are defatted — a process that removes the natural fat layer to create a whiter, smoother, easier-to-mix product.

But this convenience comes at a major cost: it strips away the delivery system and protective structures that make colostrum biologically powerful.

The fat fraction of colostrum carries growth factors, immune-supporting lipids, and the Milk Fat Globule Membrane (MFGM) — the multi-layered membrane that shields delicate proteins and helps them reach the gut intact.

When that fat is removed, these nutrients are either lost entirely or left unprotected.

What happens when colostrum is defatted:

  • Growth factors tied to the fat fraction disappear
  • MFGM is removed → loss of natural protection
  • IgG, lactoferrin, and PRPs become exposed and degrade easily
  • Casein-bound peptides drop dramatically
  • The result is a fractionated, overprocessed isolate — not true colostrum

Why it matters:

Whole colostrum is a *system*, not a single ingredient.

Remove the fat, and you remove the structure that keeps its bioactives active and effective.

Lack of Purity & Real Testing (The Part No One Talks About)

Most colostrum powders on the market don't undergo the rigorous testing needed to confirm purity, identity, or biological activity — leaving you guessing about what's actually in the tub.

Real colostrum requires specialized assays to verify that it's real, active, and free from contamination. Many brands simply don't run them.

What happens when purity isn't tested:

  • Is it even colostrum?

    Without radial immunodiffusion (RID), brands can't confirm colostrum identity or active IgG presence.

  • Potential contaminants go unchecked:

    Heavy metals, pesticides, herbicides (like glyphosate), and microplastics can slip through.

  • Bioactivity isn't verified:

    Tests like HPLC, ELISA, and RID are required to confirm that immunoglobulins and peptides remain intact after processing.

Why it matters:

If the product isn't tested, it might not be colostrum.

Purity and bioactivity aren't marketing terms. They're measurable.

If the colostrum is not real then it will not live up to the promise you've been sold.

Absolute Gold!

I work as a registered nurse in a hospital ER. I truly believe this has helped keep me from getting COVID/Flu/RSV this winter season.

Our ER is packed with these illnesses daily and while all of my coworkers have gotten sick, I have not!

I also give it to my 15 month old and she hasn't been sick since starting it a few months ago either. They have been gold for us!!

Great for the Whole Family

As a mom of four, we love the colostrum from Heart & Soil. I put it in smoothies and protein shakes. I add to yogurt parfaits and cottage cheese with honey!

I made homemade popsicles and added it was well! A easy way to make nutrient dense food for my kids!!

Love this stuff

My daughter and I have been taking this for about two months now… school is in full swing and everyone around us is getting sick…. I was skeptical to attribute it to this but I really do think incorporating this into our daily morning has been a huge catalyst to avoiding the back to school gunk.

The purest colostrum available.

Support immunity. Strengthen gut health. Speed recovery.

Immune Support You Can Feel

Immune Support You Can Feel

  • Whole, uncut colostrum delivers the full spectrum of bioactive immunoglobulins, peptides, and lactoferrin your immune system relies on.
  • When colostrum is kept intact, its immune-supporting molecules remain active — ready to tag pathogens, supports balanced inflammation response, and fortify your defenses from the inside out.
  • No isolates. No denatured proteins. Just nature's original immune blueprint.
  • Stronger immunity starts with keeping colostrum whole.
A Stronger, More Resilient Gut

A Stronger, More Resilient Gut

  • Uncut colostrum naturally supports gut lining integrity and a healthy microbiome.
  • The bioactive compounds in whole colostrum — including PRPs, growth factors, lactoferrin, and oligosaccharides — work together to nourish beneficial bacteria and help maintain a strong intestinal barrier.
  • When the gut is protected, the whole body benefits.
  • Support your microbiome. Strengthen your gut. Restore your foundation.
Natural Strength & Recovery

Natural Strength & Recovery

  • Growth factors preserved in complete colostrum are known to help your body repair, rebuild, and recover faster.
  • Colostrum's fat fraction carries essential growth factors like IGF-1 and TGF-β — compounds that support muscle repair, tissue regeneration, and resilience after stress.
    By keeping colostrum uncut, these molecules stay active and deliver real results.
  • Repair faster. Perform better. Recover the way nature intended.
