Take freeze-dried colostrum supplement for adults
Berg mounts a comprehensive case that colostrum is more than an infant first-food—it's a therapeutic supplement across the lifespan. He draws from its natural design: high levels of probiotics (including the oxytocin-boosting Elutery), prebiotic HMO, stem cells, cholesterol, omega-3 fats, and hormones. The colostrum essentially 'programs' the infant immune system, but its active constituents aren't fully degraded in the adult gut, where they can modulate immunity, heal intestinal permeability, and possibly influence systemic inflammation. He connects the dots to the thymus, the master immune gland that shrinks with age; colostrum contains factors that support thymic function, potentially enhancing T-cell production. The list of conditions he ties to colostrum—long COVID, Hashimoto's, Lyme, arthritis—suggests he views it as a broad-spectrum immune modulator. The practical guidance is sharp: heat processing destroys bioactivity, so only freeze-dried colostrum retains its potency. He implies that many people are missing these immune benefits, especially if they were formula-fed or took antibiotics, but supplementation can partially restore them.
Colostrum's mechanisms are multifaceted. The probiotics (like L. reuteri) increase gut oxytocin availability, contributing to stress reduction and social bonding via the gut-brain axis. The prebiotic HMO feeds beneficial gut bacteria, fostering a microbiome that educates the immune system. Stem cells present in colostrum may participate in tissue repair and immune system ontogeny. Immune peptides and growth factors directly modulate cytokines, promote intestinal epithelial repair (tight junction strengthening), and support the thymus's continued output of naïve T cells. The thymus-shrinkage with age leads to immunosenescence, and colostrum's thymic peptides or small molecules may mitigate this decline. The anti-inflammatory effects help break the cycle of chronic inflammation seen in autoimmunity and leaky gut.
Berg lives on a farm and observes that when a ewe dies, the lambs without colostrum 'a lot of times they won't make it.' He uses this to underscore the life-or-death importance of colostrum in nature, implying that humans similarly require these early immune gifts, though adult supplementation can compensate later.
If you have a leaky gut, if there's damage in your gut, you need to take colostrum. It has significant gut healing power.
