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.

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.

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.
