Scientific Name(s):Bovine colostrum
Common Name(s): Cow milk colostrum
Bovine colostrum has been used to treat diarrhea, to improve GI health, to boost the immune system.
Bovine colostrum is a difficult preparation to standardize because its antibody content may vary widely. Some clinical studies have been performed with hyperimmune colostrum, which may have a specific antibody titer; however, most products do not meet this criterion. Studies administering 25 to 125 mL of liquid formulations or 10 to 20 g of dry powder have been reported.
Contraindications have not yet been identified.
Information regarding safety and efficacy in pregnancy and lactation is lacking.
None well documented.
Bovine colostrum is well tolerated. A few symptoms, including mild nausea and flatulence have been reported.
Bovine colostrum appears to be safe and effective. There is no data in the literature concerning any toxicities.
Colostrum is the premilk fluid produced from mammary glands during the first 2 to 4 days after birth. It is a rich natural source of nutrients, antibodies, and growth factors for the newborn. 1
Colostrum contains immune factors, immunoglobulins, antibodies, proline-rich polypeptides (PRP), lactoferrin, glycoproteins, lactalbumins, cytokines (eg, interleukin 1 and 6, interferon γ), growth factors, vitamins, and minerals. 1 , 2 , 3 , 4 , 5 Specific bovine colostrum growth factor has been purified, stimulating synthesis of certain cell lines, for example. 6 Colostrokinin is also a constituent isolated from bovine colostrum, responsible for uterine and intestinal contraction, and lowering of blood pressure. 7
Uses and PharmacologyImmunostimulant
Certain immune factors and antibodies also fight a variety of organisms, allergens, or toxins including pneumonia, candida, and flu. Constituent lactoferrin prevents pathogens from getting the iron they need to flourish. Lactalbumins and cytokines (interleukin 1 and 6, interferon γ) are also important as antivirals and anticancer agents. 5Antidiarrheal and GI aid
Several studies show how bovine colostrum concentrates, including G immunoglobulin isolates, are highly successful alternative agents used to improve GI health and to treat diarrhea caused by a variety of pathogens. In > 50% of AIDS patients, diarrhea and subsequent weight loss pose a problem. The severity of symptoms in some cases and sometimes unidentifiable pathogens unaffected by antibiotics welcome alternative therapy with bovine colostrum.Animal data
Using a specialized colostrum preparation in animal studies, bovine colostrum has been shown to have a high capacity for neutralization of bacterial toxins and high effectiveness in treating severe diarrhea. 18
Bovine colostrum supplementation, in another report, has been shown to prevent NSAID-induced gut injury in various in vivo and in vitro models, suggesting its possible usefulness for certain ulcerative bowel conditions. 1Clinical data
In one study, 29 AIDS patients received a bovine colostrum preparation. The average stool per day decreased from 7.4 before therapy to 2.2 after treatment. 19 A 25-patient study of HIV subjects with chronic diarrhea administered bovine colostrum preparation also confirms therapeutic effectiveness, resulting in 64% of patients experiencing complete (40%) or partial (24%) remission of diarrhea. 20 Cryptosporidium , a human GI parasite, can also cause life-threatening diarrhea in immunodeficient patients when antibiotics or other anti-diarrheals may be ineffective. Bovine colostrum therapy has reduced significantly oocyst excretion of pathogen in stools vs placebo and relieved a previously untreatable AIDS patient of severe Cryptosporidium -associated diarrhea. 21 , 22 Lactobin , a registed bovine colostral product, shows antibody reactivity and neutralization against certain E. coli strains and shiga-like toxins. 23 Immunoglobulin preparation supplementation was found to protect against Shigellosis ( S. flexneri ), and suggests its usefulness in high-risk groups including travelers and military personnel during Shigella outbreaks. 24 Bovine colostrum use against organisms Yersinia enterocolitica and Campylobacter jejuni has also been reported. 25 Bovine colostrum also inhibits Helicobacter pylori and Helicobacter mustelae by binding to certain lipid receptors, which may modulate the interaction of these pathogens to their target sites. 26 One report investigates the bovine colostral immunoglobulin proteins and how they are subject to degradation by gastric acid and intestinal enzymes under certain conditions. 27Other uses
The immune-boosting properties of bovine colostrum have been promoted as performance enhancers and anti-aging/healing supplements. Certain Web pages, for instance, promote significant fitness gains for athletes, noting its “anabolic effects” and claiming it can “promote muscle growth.” 28 One clinical trial finds bovine colostrum supplement to increase serum IGF-1 concentration in athletes. 29 IGF-1 is a growth factor that speeds up protein synthesis and slows catabolism. 23

Information regarding safety and efficacy in pregnancy and lactation is lacking. Avoid use.
None well documented.
A few symptoms, including mild nausea and flatulence, were seen in certain trials, but most have reported bovine colostrum to be well tolerated. 18 , 19 , 20 At least 2 allerginicity studies have been performed in humans. 34 , 35
There is no major toxicity associated with bovine colostrum supplementation.
