In a recent NPR report, science reporter Ari Daniel examines whether the science behind colostrum supplements backs the hype. Colostrum, he explains, is the first milk a mammal produces after birth, long called “liquid gold” for the antibodies and nutrients that help a newborn’s immune system and gut. Daniel notes it has become a wellness trend for adults, with influencers promoting cow-derived colostrum supplements for gut health.
The claim
Daniel notes that social media is full of videos touting colostrum’s benefits, especially for gut health, as well as immunity, skin, hair, and energy. He explains that cows produce excess colostrum beyond what their calves require, and that this surplus is collected, pasteurized, dried, and sold as a supplement.
The evidence
Daniel describes the evidence for colostrum as encouraging but preliminary. He reports that animal research and a small number of human studies suggest it may benefit conditions such as inflammatory bowel disease, gastroenteritis, and respiratory infections. He quotes gastroenterologist Raymond Playford, a longtime colostrum researcher, who says it may help strengthen the gut lining and points to a pilot study suggesting it could reduce some side effects of GLP-1 drugs like Ozempic. Daniel also notes that Playford serves as medical director of of PanTheryx, a company that produces colostrum.
For a more skeptical perspective, Daniel turns to dietitian Elyce Shapiro. “I just don’t think that we know enough yet,” she told Daniel, pointing out that most of the research has focused on specialized groups rather than people seeking relief from common digestive issues.
Cautions and alternatives
Daniel reports that both Shapiro and Rick Bloomer, a University of Memphis nutrition scientist, say lifestyle comes first. Bloomer tells him much of the marketing is overblown and stresses that regular exercise, a good diet, and enough sleep matter most, while Shapiro adds managing stress to the list. If someone still wants to try colostrum, Daniel writes, Bloomer suggests taking it consistently for about two months without changing anything else, so any effect is clear.
Bloomer also points out that the cost, which can range from a dollar to two dollars a day, might be better spent on nutritious food. Daniel adds another caution from Playford: individuals with a milk allergy should avoid this product.
The bottom line
Daniel concludes that the research suggests potential benefits for gut health, but it’s still in its early stages, and colostrum isn’t a quick fix. For everyday gut issues, experts recommend lifestyle changes as the first step.
