The researchers suggested that higher saliva levels of IgA may strengthen immunity and enhance the body’s ability to fight upper respiratory tract infections (7).
In another study with 29 male cyclists, researchers observed that taking 10 grams of bovine colostrum a day for 5 weeks prevented a post-exercise decrease in immune cells and reduced the risk of upper respiratory infection symptoms compared to a placebo (8).
Other studies have similarly linked bovine colostrum supplements with an enhanced immune response (9). The result is colostrum seems to give the immune system a boost that can reduce the risk of sickness or prevent athletes from falling ill due to a weakened immune system following heavy training sessions.
MAY BENEFIT GUT HEALTH
Research suggests bovine colostrum can strengthen your gut and fight infections in the digestive tract.
Both animal and human studies show that bovine colostrum may stimulate the growth of intestinal cells, strengthen the gut wall, and prevent intestinal permeability, a condition that causes particles from your gut to leak to the rest of your body (17, 18, 19).

These beneficial effects are likely due to the lactoferrin and growth factors bovine colostrum contains (20, 21).
One study in 12 athletes who were susceptible to intestinal permeability due to heavy exercise found that taking 20 grams of bovine colostrum a day prevented 80% of the increase in intestinal permeability experienced by those who took a placebo (18).
Another study observed that colostrum enemas may be helpful in treating colitis, a condition characterized by inflammation of the inner lining of the colon. Colitis can be associated with diarrhea, abdominal pain, bloating, blood in the stool, loss of blood supply to the colon, and more.
A study in 14 adults with colitis who were taking traditional medications found that taking bovine colostrum enemas in addition to regular medications reduced symptoms more than medication alone (22).
The potential for bovine colostrum to reduce symptoms of colitis is supported by animal studies. However, researchers agree more extensive research in humans is needed (23, 24).
For a healthy body and a strong immune system, your gut health is vital. Although research is ongoing, strong evidence has shown how much a game changer bovine colostrum can be, especially in strengthening the wall of the intestines and combating intestinal permeability.
