Colostrum and Immunity

Feel The Power of 100% Pure 4 Hour Colostrum.

While in the womb the unborn relies on the immune system of the mother. When it is born it has to fend for itself. This means its immune system has to be awakened, stimulated, balanced, and fortified immediately. That is where colostrum comes in. The first colostrum is rich in immune factors. The earlier colostrum is collected the richer it is. Colostrum transitions to plain milk hour by hour post calving, with the concentration of immune factors and other vital components decreasing dramatically around the four to six hour time frame. Goettsche Labs is collected within four hours post calving after the calves have their fill. Most colostrum on the market is harvested within a 16 to 24 hour time frame and cannot be expected to provide immunity benefits and other benefits that Goettsche Labs colostrum does.

How Colostrum4® Supercharges Immunity

Whole, intact, and pure 4 hour colostrum4® is packed with nature’s full, balanced array of bioactive components that work synergistically to fortify the immune system. These include:


IgG (Immunoglobulin G): IgG is the most abundant type of antibody in colostrum and provides passive immunity to the newborn. It is transferred from the mother to the offspring through the placenta during pregnancy and via colostrum after birth.

IgA (Immunoglobulin A): IgA is another important antibody present in colostrum. It plays a crucial role in protecting mucous membranes, such as those in the respiratory and gastrointestinal tracts, from infections.

IgM (Immunoglobulin M): IgM antibodies are also present in colostrum, although they are found in lower concentrations compared to IgG and IgA. IgM antibodies are the first line of defense against new infections.

Other Immunoglobulins: In addition to IgG, IgA, and IgM, colostrum may contain smaller amounts of other immunoglobulins such as IgD and IgE.

Cytokines: These are small proteins that regulate the immune response by promoting communication between cells. They play a vital role in modulating the immune system’s activity.

Growth Factors: Colostrum contains growth factors such as insulin-like growth factor 1 (IGF-1) and transforming growth factors, which support the development and maturation of the gastrointestinal tract and immune system.

Lactoferrin: This iron-binding protein found in colostrum has antimicrobial properties and helps in preventing the growth of bacteria and viruses.

Leukocytes: Stimulate the production of interferon which slows viral reproduction.

Lysozyme: Destroys harmful bacteria and viruses.

Proline-Rich Polypeptides: Immune system regulator, initiating and suppressing the immune system. Suppressing the immune system is necessary to prevent it from attacking harmless antigens and the body itself.

Interlukin-10: Significantly reduces inflammation cause by arthritis, infection or injury.

Lymphokines: Regulate the immune response.

Even the fat in colostrum contains various bioactives that contribute to its health benefits. Some of the bioactives found in colostral fat include:

1. Medium-Chain Fatty Acids (MCFAs): Colostrum fat contains medium-chain fatty acids such as caprylic acid, capric acid, and lauric acid. These MCFAs have antimicrobial properties and can support immune function.

2. Phospholipids: Phospholipids are a class of lipids that are essential for the structure and function of cell membranes. They play a crucial role in cellular signaling and transport processes.

3. Conjugated Linoleic Acid (CLA): Colostrum fat also contains conjugated linoleic acid, which has been studied for its potential health benefits, including anti-inflammatory and immune-modulating properties.

4. Growth Factors: Colostrum fat contains growth factors such as insulin-like growth factor 1 (IGF-1) and transforming growth factor beta (TGF-β), which play important roles in tissue growth and repair.
