Colostrum, known as “liquid gold,” is the first milk that mammals produce after giving birth. It is rich in antibodies, proteins, vitamins and minerals essential for the development of the immune system and intestinal health of newborns. In the case of cows, production exceeds the needs of their calves, allowing collection and processing for human consumption.

Various personalities on social networks have now taken on the task of promoting bovine colostrum as a key supplement to improve intestinal health and other benefits, draws attention to the contributor to the Science section of National Public Radio (NPR), Ari Daniel.

The influencers' claims include the possible effectiveness of bovine colostrum to treat gastrointestinal problems, strengthen the immune system and improve the appearance of the skin.

Contrary to this trend, although preliminary research suggests that colostrum could help with certain disorders, the medical community warns that current knowledge is limited, and experts note that more research is required to confirm these benefits and determine that dosing guidelines are often ambiguous.

Alternatives and recommendations

Nutritionists advise prioritizing lifestyle changes, such as improving diet, increasing physical activity and managing stress, before turning to supplements. If you decide to use colostrum, it is recommended to do so consistently and in a controlled environment to evaluate effectiveness.

“To think I can use a supplement but ignore those other factors is a big mistake,” says Rick Bloomer, a nutrition scientist and dean of the School of Health Sciences at the University of Memphis, who calls much of the marketing “overblown.”

Despite the low incidence of side effects, people with dairy intolerances are warned to avoid its consumption. Experts suggest paying attention to the cost-effectiveness of supplements, given the benefits of an adequate diet rich in fruits and vegetables.

Research on bovine colostrum continues to develop. While there is promising evidence regarding its benefits for gut health, it is essential to evaluate these findings with caution and not consider them as a quick fix to health problems.

Difference between human colostrum and human colostrum

The main difference between bovine and human colostrum is their immunoglobulin content.

Bovine colostrum is much richer in IgG (immunoglobulin G), while human colostrum has a predominance of secretory IgA, which is crucial to protect the baby's intestinal tract.

Risk groups and contraindications

Long-term theoretical concern. There is theoretical concern about bovine spongiform encephalopathy (BSE/mad cow disease), as the pathogen could be transmitted to bovine products and be linked to Creutzfeldt-Jakob disease in humans, although there is no clear evidence that this occurs with dairy products such as colostrum. It is recommended to avoid colostrum from countries with BSE cases.

Bovine colostrum appears safe for moderate use in healthy adults without dairy allergies, but human studies are still lacking to confirm long-term safety. Adverse effects are usually mild and resolve by reducing intake.
