Colostrum, often dubbed "nature's first food" or "liquid gold," is a thick, yellowish fluid produced by the mammary glands of mammals, including humans and cows, in the initial days after giving birth. While colostrum is well-known for its benefits to newborns, particularly in bolstering their developing immune systems, its potential advantages for adults, especially in areas like weight management, have garnered increasing attention. This article provides a comprehensive overview of colostrum supplements, focusing on their potential weight loss benefits, supported by scientific evidence and expert opinions.
What is Colostrum?
Colostrum is the first nourishment a newborn receives after birth. It differs significantly from mature breast milk, boasting a higher concentration of protective compounds. This includes antibodies, growth factors, enzymes, and other essential nutrients crucial for a newborn's healthy development. In recent years, bovine colostrum, derived from cows, has become a popular supplement for adults, available in various forms such as powders, pills, and topical creams.
Colostrum Composition and its Importance
Compared to mature milk, colostrum has more fat, protein, vitamins and minerals, growth factors, cytokines and nucleotides that provide immune support, and less lactose. All female mammals, including humans, produce colostrum in the days after giving birth. Colostrum provides newborns with nutrients that help strengthen their delicate immune system.
Colostrum Supplements: Potential Benefits for Adults
Colostrum supplements are widely marketed for various health benefits, including improved gut health, immune system support, and enhanced exercise recovery.
Immune System Support
Like in babies, colostrum helps support adults’ immune systems. Colostrum also has proline-rich polypeptides, which can balance the immune response by boosting an underactive immune system or calming an overactive one.

Gut Health Improvement
Colostrum is loaded with digestive enzymes that help break down proteins, fats and fiber. Bovine colostrum may reduce inflammation and gut permeability, which can help support a healthy gut microbiome. These studies show bovine colostrum may help people who have gastrointestinal issues (GI) like Crohn’s disease and inflammatory bowel disease (IBD).
Exercise Recovery Enhancement
Studies suggest that colostrum supplements help speed up recovery after intense physical activity and reduce muscle damage. Early data is most convincing in high-intensity athletes, according to Zaslow, where supplementing colostrum could curb inflammation and muscle-related injuries. One study showed squat-jump athletes slightly enhanced recovery time after an intense workout.
Anti-Aging Properties
Colostrum's growth factors also contribute to skin health. By stimulating the production of collagen, colostrum helps maintain firm, youthful-looking skin.
Colostrum and Weight Loss: Exploring the Connection
Some research indicates that colostrum supplements might help with weight management. The growth factors found in colostrum may help regulate metabolism and promote fat loss while preserving lean muscle mass.
Mechanisms of Action
- Metabolism Regulation: Growth factors in colostrum, such as insulin-like growth factor 1 (IGF-1), may influence metabolic processes, potentially leading to increased energy expenditure and fat oxidation.
- Muscle Mass Preservation: Colostrum supplementation, particularly when combined with resistance training, may help preserve or even increase lean muscle mass. Muscle tissue is metabolically active, contributing to a higher resting metabolic rate, which can aid in weight loss.
Scientific Evidence
Two small studies of active, healthy participants found that supplementing colostrum alongside resistance training for two months boosted muscle mass and lowered body fat.

Colostrum in Sports and Athletic Performance
Colostrum is also gaining ground in sports, with athletes turning to the popular supplement to level up every jump, sprint and backhand swing. Claims that colostrum supplements can boost athletic endurance are enticing but controversial, Dike said. Insulin growth factor 1 and transforming growth factor beta, which naturally aid in tissue repair and rejuvenation, are both only innate in colostrum.
Considerations before Taking Colostrum Supplements
If you’re interested in taking colostrum supplements, they are available in various forms, including powder, pill (capsule) and even creams for topical use.
Quality and Safety
When choosing a colostrum supplement, it’s important to pursue products that ensure the highest quality and safety. Look for non-GMO, organic bovine colostrum from ‘grass-fed’ or ‘pasture-raised’ cows.
Potential Side Effects and Risks
Colostrum supplements are safe for most people. However, some may experience mild digestive discomfort, such as bloating or nausea, especially when starting the supplement. Those with dairy allergies, autoimmune conditions or compromised immune systems should exercise caution.
Lack of Regulation
Food and Drug Administration (FDA). Czerwony says that the lack of regulation makes it hard to know if you’re getting what’s advertised on a supplement’s packaging. You don’t necessarily know that you’re getting 100% bovine colostrum because there’s no testing, so the potency can change from batch to batch, and certainly from manufacturer to manufacturer.

When it comes to recommended dosage and usage, Czerwony says that there also isn’t a standard on how to use bovine colostrum. It’s like the Wild West - people are taking whatever they want. We don’t know how much to take and we don’t know how long to take it for. Does it take four to six weeks to show any benefit? Are you going to see it in two weeks? You’re at your own risk trying this supplement.
Concerns about IGF-1
And there’s been some concern about a specific growth factor known as IGF-1 in bovine colostrum and if it can cause certain cancers like breast cancer or prostate cancer. Again, more research is needed to understand all the risks that come along with taking bovine colostrum supplements. The growth factors in colostrum are designed to help newborns grow, and so it’s not designed for adults. By exposing yourself to these growth factors that are designed for newborn cows, you may run the risk of turning on certain cells through these growth factors.
Dosage Information
The standard colostrum dose intended as a protein supplemented or intestinal health agent is between 20-60g. A colostrum dose intended to reduce the risk of E. coli-induced diarrhea should contain between 400-3,500mg of immunoglobulins. It should be taken shortly after a meal. Colostrum intended to reduce the risk of diseases related to E. coli must come from a cow (or similar animal) that has been immunized against E. coli.
Alternatives to Colostrum Supplements
Foods are always the best way to approach maximizing the power of colostrum. Probiotics provide beneficial bacteria to the gut.
Anti-Inflammatory Diet
Following an anti-inflammatory diet is good for your overall health. We know it’s good for your heart, it’s good for your gut, it’s good for your brain. Having a good anti-inflammatory diet, which includes the Mediterranean diet, has been shown time and time again as one of the best ways to eat.
