Let’s take a look at that and more about this supplement.

What Is Colostrum?

Colostrum is often referred to as liquid gold because of its nutrient-rich content that is produced during the first stage of breast milk production.

Overall, colostrum plays a vital role in strengthening the immune system. There are a few things to understand before thinking about supplementing with colostrum.

Colostrum And Bacteria

Growth Factors

Colostrum carries a variety of growth factors which is beneficial for skin rejuvenation and can reduce muscle recovery time. Growth factors are essential for cell replication, decreasing information, and collagen production.


Colostrum also contains a wide range of antibodies that plays a vital role in the immune system. The main antibodies present in colostrum are IgG, IgA, and IgM whose role is to identify, destroy, and prevent pathogens that may cause diseases.


Bovine colostrum accommodates a large number of hormones such as estrogens, progesterone, androgens, glucocorticoids, prolactin, growth hormone, and more. Hormones are chemicals in the body that have an effect on the body’s activity. They function as the sender of signals to activate metabolism, sexual drive, and reproduction, appetite, body temperature, growth and development, heart rate, sleeping and waking cycles, etc.

Main Benefits Of Colostrum

Bovine colostrum is a superfood. Researches show that bovine colostrum can give benefits not just to the newborn but also throughout childhood, adulthood, and even old age. These supplements are becoming more and more popular as many discover the benefits that come with colostrum. There are a diverse amount of benefits that come with colostrum, protecting immunity just being the beginning. 

Benefits Of Colostrum

Promotes Immunity

As mentioned, colostrum contains high levels of natural immunoglobulins that can strengthen the immune system. These antibodies act as modulators that help the immune system to regain its state of balance. 

According to studies, the administration of 20g bovine colostrum supplement has increased the production of the body’s IgA compared to young women who’s receiving skimmed milk as a supplement.

Following the use of bovine colostrum, research also shows that bovine colostrum supplementation helps treat children with respiratory tract infection due to IgA deficiency and a reduction of infection severity has also been observed. It can be beneficial during cold and flu season to fight against upper respiratory tract infections in children.

Also, bovine colostrum may help in the process of fighting off an infection. A  2012 placebo-controlled, double-blind, randomized cross-over trial revealed that a single dose of bovine colostrum remarkably increased phagocytic activity. That very same study evidences a short-term growth in natural killer cell activity within one to two hours after taking colostrum, which is an indicator that colostrum braces the immune system to fight.

Aids In Gut Health

A healthy gut contributes to overall health and well-being and colostrum can help reinforce the intestinal lining of the gut. Colostrum can hinder the development of a leaky gut, a condition wherein holes or openings are formed in the gut lining. When this occurs, food and other harmful toxins can infiltrate the gut lining, accompanying inflammation that is the basis of various digestive health issues.

Colostrum can help in restoring the gut to its normal permeability levels because it contains growth factors and hormones to assist the gut in maintaining tight-junction integrity. Decreased permeability can result in altered absorption of nutrients.

Lastly, it also carries immunoglobulins that can keep the gut microbiome. Colostrum can even stimulate the growth of good bacteria in the gut.

Natural Skin Health And Beauty

Colostrum has many repair and growth factors that may assist in the healing of tissues counting the skin, muscle, cartilage, and bone. There are quite a few animal and human studies that have investigated the specific growth factors that are naturally found in colostrum to support skin healing.

Also, colostrum may bring back the natural health and beauty of the skin because of its nutrient-rich concentration of immunoglobulins IgG, IgA, IgM, lactoferrin, growth factors, and vitamins and minerals.

Increased Athletic Performance

According to various studies, colostrum supplements may boost exercise performance. In a study conducted in 2001, scientists directed a group of athletic men and women to take either colostrum or whey protein. Each of the subjects cooperated in aerobic exercise and heavy resistance training at least three times per week during the eighth-week of the study. The group that took colostrum showed an increase in lean body mass, while the group with just whey protein experienced a notable increase in body weight.

Research has also shown that consuming colostrum supplements may be most helpful during high-intensity training and when recovery from it.
