People are always looking for ways to improve their health, and recently, colostrum has captured global attention. To find the best colostrum supplement, it’s important to first understand what colostrum is and how it works. Often called “liquid gold,” colostrum is the nutrient-packed first milk produced by mammals—including humans—in the initial days after giving birth.

“This early milk is loaded with protein, vitamins, minerals, and growth factors, which are crucial for a newborn’s immune system and digestive health,” explains Dr. Gerda Endemann, a nutrition and health expert. “It contains oligosaccharides, special carbohydrates that feed gut bacteria, along with antibodies like IgA and IgG, white blood cells, and lactoferrin—all of which help fight infections.”

Now, researchers are exploring these benefits for adults. “While research is still limited, some studies suggest bovine colostrum may support immunity, gut health, and athletic performance due to its high levels of immunoglobulins, antibodies, and growth factors,” says registered dietitian Isabel Smith.

To help you choose, we consulted experts and narrowed down the top five colostrum supplements on the market.

### Vogue’s Top Colostrum Picks:

### Best Overall: ARMRA Colostrum Powder
Why We Love It: Developed by a pediatric neurologist after her own health struggles, ARMRA is a favorite of Dua Lipa and holistic nutritionist Chelsey Wilkens. “I recommend ARMRA because it’s hormone-free, from first-day milking, and gently pasteurized to preserve nutrients,” says Wilkens, who has been taking it daily for seven months. “Its liposomal delivery boosts absorption, and the sourcing is excellent.”

The brand uses a special low-heat pasteurization process to maintain over 400 bioactive nutrients. Their colostrum comes from grass-fed cows on U.S. family farms, using surplus milk that would otherwise go to waste (calves only consume about half of what their mothers produce).

In clinical trials, 86% of users reported less bloating after three months, while 80-87% saw improvements in muscle growth, endurance, and recovery. Vogue’s Kiana Murden tested it for six months and was most impressed by its immune benefits. “I used to get terrible winter colds, but since taking ARMRA, I haven’t been sick at all,” she wrote. Experts believe colostrum’s immune-boosting compounds, like immunoglobulins, may help reduce infections.

### Everything You Need to Know

#### What is colostrum?
Colostrum is the first milk mammals produce in the days after giving birth—it’s thicker and yellower than regular breast milk, earning it the nickname “liquid gold.”

“Colostrum is packed with polyunsaturated fats, antibodies, protein, growth factors, vitamins, and minerals that help build an infant’s immune system,” explains Smith. Bovine colostrum supplements come from cow’s milk, but other types exist. “Most colostrum supplements are from cows, but goat and sheep versions are also available,” says Endemann.

#### Are colostrum supplements worth it?
It depends on your goals. Studies show benefits for preterm infants given their mother’s colostrum, but the evidence for commercial bovine colostrum—often used for immunity and gut health—is less clear.

“It’s appealing to think we can buy concentrated antibody supplements to fight infections,” says Endemann. However, it should be used as a supplement, not a cure-all.

#### What are the benefits of colostrum supplements?
Colostrum is believed to support immunity, hair growth, skin health, bloating relief, and gut issues—though more research is needed for definitive proof.

Early studies suggest bovine colostrum may help with gastric symptoms in celiac disease and colitis, as well as reducing leaky gut. A 2024 review (sponsored by a Chinese biotech company) noted potential immune benefits.

Athletes also use it for gut health, stomach discomfort, and immune support. “Research has looked at colostrum for GI health, athletic performance, and preventing diarrhea and respiratory infections,” says Endemann. “Results are mixed, so more controlled studies are needed.”

#### Are there any downsides to taking colostrum?
Colostrum is generally considered safe, but since the FDA doesn’t regulate supplements, caution is advised—especially with products claiming to treat medical conditions.

“There’s a moderate downside because it’s unregulated,” says Wilkens. “But since it’s relatively new, there haven’t been major production issues.” If you’re pregnant, nursing, on medication, or have a medical condition, consult your doctor before use.

#### What to Look for in Colostrum Supplements
Transparency is key. “Choose a product with minimal additives, made in a GMP- and FDA-certified facility, and with high IgG content,” says Smith.Here’s a natural, fluent rewrite of your text while preserving the original meaning:

Low-heat or cold-processed manufacturing helps retain most of the benefits, and the colostrum should come from grass-fed, antibiotic-free cows.

Ethics and sourcing are also important considerations. Some argue that harvesting colostrum—which is only produced for about 1-4 days before milk comes in—deprives calves of the essential nutrients they need after birth. However, companies like ARMRA follow a “calf-first” approach. Dr. Sarah Rahal, ARMRA’s founder and CEO, explains: “We only collect surplus colostrum—what’s left after calves are fully nourished. Normally, this excess is discarded as waste, but we upcycle it to ensure nothing goes to waste while prioritizing the calves’ health.”

### Who Should Avoid Colostrum?
Colostrum supplements are generally safe for most people, but cow and human colostrum differ in composition. “Bovine colostrum is safe for human consumption, but research on its benefits and safety is ongoing,” says Gerda Endemann, PhD. “It contains higher levels of casein and antibodies than human colostrum, along with immune-regulating compounds like lactoferrin, EGF, and IGF-1.”

However, those with dairy allergies or lactose intolerance should avoid it, as it contains lactose and casein. Isabel Smith, RD, adds: “People with autoimmune conditions, histamine intolerances, or compromised immune systems should also be cautious, as colostrum may stimulate immune activity.”
