Curated, not stocked.
Colostrum is one of the more evidence-backed whole-food supplements for gut and immune support, yet it rarely appears in mainstream ranges. Heart & Soil's commitment to grass-fed sourcing aligns with the quality standards our doctors apply when selecting animal-derived products. We recommend it particularly for patients with confirmed gut permeability concerns or those in sustained high-output training who want mucosal immune support beyond what standard vitamin protocols offer.
About this product
Grass-Fed Colostrum
Heart & Soil Grass-Fed Colostrum is a bovine colostrum supplement drawn from the first milk produced after calving — a concentrated source of immunoglobulins, lactoferrin, growth factors, and proline-rich polypeptides that are not present in meaningful quantities in ordinary dairy. Colostrum has been studied for its potential to support intestinal barrier integrity, immune modulation, and recovery, making it a practical consideration for anyone dealing with gut permeability, frequent illness, or heavy physical training.
It suits a fairly broad range of people: those with a history of digestive complaints, individuals in demanding training blocks who want to support mucosal immunity, or anyone whose diet has historically been low in whole-animal nutrition. Colostrum occupies a distinct niche — it is not a probiotic, not a protein powder, and not a standard immune supplement. Its bioactive fractions work at the mucosal level in ways that more common supplements do not replicate.
Heart & Soil is a brand built around nose-to-tail, animal-based nutrition, and their colostrum is sourced from grass-fed cattle. The "grass-fed" designation matters here because the fatty acid profile and immunoglobulin content of bovine colostrum can vary with the animal's diet and management conditions. As with any product containing bovine-derived immunoglobulins, those with a dairy allergy should seek clinical guidance before use.

Common questions
Frequently asked
What makes bovine colostrum different from a standard immune supplement?
Bovine colostrum contains immunoglobulins (particularly IgG), lactoferrin, and proline-rich polypeptides that act at the mucosal lining of the gut. Most immune supplements — vitamin C, zinc, elderberry — work through different mechanisms. Colostrum is specifically studied for intestinal barrier support and mucosal immunity, which sets it apart from more general immune formulas.
Is this suitable if I have a dairy allergy or lactose intolerance?
Bovine colostrum is derived from milk and contains dairy proteins, so it is not appropriate for those with a confirmed dairy or milk protein allergy. If you are lactose-intolerant rather than allergic, tolerance can vary — check the packaging for lactose content and consult your doctor if unsure.
Who would benefit most from taking colostrum?
Those most likely to notice a difference include people with gut permeability concerns, athletes in heavy training blocks, and individuals who experience frequent upper respiratory infections. It is also a reasonable addition for anyone following an animal-based or ancestral nutrition protocol who wants to include bioactive fractions not found in muscle meat alone.
How long before I notice any effect?
Gut and immune-related changes from colostrum supplementation are generally gradual. Most people who notice a difference report it over several weeks of consistent use, rather than days. As with all supplements, individual response varies and results are not guaranteed.
Can I take this alongside other supplements or medications?
Colostrum is generally considered low-risk alongside common supplements. However, if you are on immunosuppressant medication or have an autoimmune condition, speak to your doctor before adding any immune-modulating supplement, including colostrum, to your routine.
