The 5 best colostrum supplements, reviewed by a registered dietitian

Colostrum is a thick, nutrient-rich liquid released by the breasts in the days after giving birth that has always been an important source of nutrients for newborns. Now, emerging research suggests it may benefit adults as well. Several small studies link bovine colostrum supplements from cows to improvements in gut health, gastrointestinal diseases, viral infections, and joint pain. (1, 2)  

Additionally, there’s evidence that the best colostrum supplements may be particularly beneficial for athletes, helping to improve exercise recovery, prevent injuries, and support immune health. However, further studies are needed to understand the relationship between bovine colostrum supplements and human health. (3)

Colostrum supplements often differ in their concentration of immunoglobulins (antibodies), form, price, and sourcing method. With a plethora of options to choose from, finding the right one can be overwhelming.

Our team of fitness and nutrition experts spent hours researching and analyzing dozens of colostrum powders to help you narrow down the best colostrum supplement for your unique needs. Here are the five colostrum supplements that came out on top.

Editor’s choice: Nutricost Colostrum

Nutricost Colostrum Powder is a well-rounded bovine colostrum supplement, standardized to deliver a high concentration of immunoglobulins in every batch. Plus, at just $0.47 per serving, it’s also the most affordable option in our lineup, earning our pick for Editor’s Choice.

What you should know

Nutricost Colostrum Powder is a budget-friendly option that’s third-party tested and standardized to contain at least 30% IgG antibodies. This potent colostrum supplement easily earns our top pick for best for gut health.

  • Nutricost Colostrum Powder is not 100% pure colostrum, as it contains milk protein concentrate, non-fat dry milk, and small amounts of medium chain triglycerides (MCTs), sunflower lecithin, and natural flavor. 
  • At just $0.79 per serving, Nutricost Colostrum is our list’s most affordable colostrum powder.
  • Folks who prefer a colostrum supplement without any additives may find better value in another brand, such as ARMRA colostrum. 

The recommended serving is one scoop mixed with 6-10 ounces of water. Avoid mixing colostrum powder with hot liquids, which may alter its effectiveness. Colostrum is sensitive to heat, with studies showing that its proteins may begin to denature when it’s exposed to temperatures above 140°F. (22)

Why we like Nutricost Colostrum as best for gut health

Nutricost Colostrum Powder is a good quality colostrum supplement that packs in 3,000 milligrams (mg) of cow colostrum per one-scoop serving. It’s non-GMO, gluten-free, and unflavored, making it easy to mix into most beverages.

This colostrum powder stands out for its high immunoglobulin G (IgG) concentration, guaranteeing at least 30% of your daily recommended amount per serving.

IgG antibodies, lactoferrin, growth factors, and other bioactive compounds provide passive immunity to offspring, protecting them against infections and pathogens. (2)

The effect of IgGs on the immune system may be one of the main contributors to the potential health benefits of colostrum supplements. Yet more research is needed to determine the most effective concentration. Generally speaking, a higher IgG concentration is considered better. (2) “It can also be helpful with decreasing inflammation from a heavy workout load,” adds Victoria Burgess, PhD, CSCS, CISSN. 

A 2022 review found that bovine colostrum supplements may improve gut health in athletes by maintaining a strong gut lining and preventing harmful bacteria from entering the bloodstream. (4)

Nutricost supplements are made in the United States in a Good Manufacturing Practices (GMP) certified facility. The FDA requires supplement companies to follow GMP guidelines to reduce the risk of contamination and ensure quality, purity, and strength. The FDA periodically tests GMP-certified facilities to ensure compliance with guidelines.

Also, each batch undergoes third-party testing to validate the quality and safety of its ingredients, although we couldn’t find details on what is tested.

Unfortunately, Nutricost doesn’t disclose whether their colostrum is sourced from grass-fed or grain-fed cows, nor do they provide details on how the colostrum is collected and sterilized. These details are important, as the cow’s diet, environmental conditions, collection time, and sterilization techniques can impact the colostrum quality. (5)

On the positive side, Nutricost offers a generous 60-day money-back guarantee if you’re unhappy with your supplement. You must purchase directly from the Nutricost website to take advantage of this offer.

What customers are saying

With over 100 reviews on Amazon, many customers are happy with Nutricost Colostrum Powder. They say it dissolves well in liquids without lumping and has a neutral taste.

“Good quality product; seems competitively priced against similar powders (sales and incentives always welcomed). Dissolves easily enough without any real lumping. No negatives in taste or smell.” 

Rob, Amazon

A few customers express disappointment with the brand’s lack of transparency. 

Amazon customer Janice G. says,” The product is advertised with a label pictured with colostrum as the sole ingredient. That is NOT what I have in front of me. The product I received, which I just opened now, indicates milk protein concentrate, non-fat dry milk, and sunflower lecithin, among other things. Misleading and disgusting. I do not want to be ingesting powdered nonfat dry milk. I know what colostrum is, consistency, taste. I have taken multiple brands. This is the only one that has the rough, grainy texture of powdered milk.”

What you should know

ARMRA’s Immune Revival Colostrum is made with pure colostrum sourced from grass-fed cows raised on family-owned farms in the United States. It utilizes proprietary technology to preserve nutrients and increase absorption.

  • ARMRA Colostrum is grass-fed, certified glyphosate-free, non-GMO, and sustainably sourced to ensure quality and animal welfare.
  • At $0.92 per serving, ARMRA Colostrum falls in the middle of the price range for colostrum supplements. However, the brand recommends gradually increasing to up to three scoops daily, tripling the daily cost.
  • ARMRA Immune Revival Colostrum may be an excellent choice for people searching for a pure, grass-fed colostrum supplement.
  • The recommended serving size is one scoop–about one-half of a teaspoon–mixed into a cool liquid or scooped directly into your mouth.
Pros
Keto-certified and soy-free
Third-party tested

No artificial sweeteners, colors, or additives
Cons
Proprietary blend makes it difficult to know the product’s exact contents
Flavored varieties cost more than the unflavored option

Why we like ARMRA Colostrum as best for adults

ARMRA’s Immune Revival Colostrum is a premium colostrum supplement sourced from grass-fed, antibiotic- and hormone-free cattle within 24 hours of delivery, making it our best pick for adults seeking superior quality.

The physician-owned company stands out for its Cold-Chain BioPotent Pasteurization–a low-temperature process designed to preserve over 400 vitamins, minerals, antioxidants, and other nutrients while improving absorption. However, the vitamin and mineral concentration is likely not high enough to replace the best multivitamins.

ARMRA claims this technology removes all of the casein, the root of many dairy allergies. However, since it is still derived from dairy and contains a small amount of lactose, people with a true dairy allergy and/or lactose intolerance should speak to their healthcare provider before use.

This colostrum supplement comes in three flavor options: unflavored, blood orange, and vine watermelon.  People looking for a clean, pure colostrum powder will appreciate the unflavored powder, free of additives and made with 100% grass-fed bovine colostrum. 

The flavored options use organic ingredients and are sweetened with stevia, a plant-based sweetener considered safe but sometimes avoided by people who may experience a bitter aftertaste.

ARMRA’s colostrum supplements are keto-certified, soy-free, and tested in-house by a third party for heavy metals, contaminants, and glyphosates (pesticides). We appreciate ARMRA’s commitment to animal welfare, making sure calves are fully fed before collecting the overflow colostrum left over.

Each scoop serving contains 1,000 mg of a proprietary blend of bovine colostrum, lower than many other colostrum supplements. ARMRA states that its colostrum is more potent than competing brands with higher amounts. But since it’s made up of a proprietary blend, we have no way of knowing its exact contents and percentage of immunoglobulins.

At $0.92 per one-scoop serving, ARMRA Colostrum Immune Revival is average in price compared to similar colostrum supplements. However, costs can add up quickly if you follow the brand’s recommendation to gradually increase to 2–3 scoops per day, which can cost up to $2.76 per day. 

Also, the flavored options are even pricier, averaging around $1.33 per one-scoop serving. However, the quality and purity may make it worthwhile if you prioritize these factors.

What customers are saying

ARMRA’s Immune Revival Colostrum has over 3,000 reviews on Amazon, with most being positive. Many customers are happy with the supplement’s quality and report noticeable improvements in hair, skin, and gut health.

“This colostrum is the best on the market! There has been so much testing on the quality and performance of this product, and you can tell! I feel way more supported having such a great superfood in my diet!!”

Sophia M., Amazon

However, not all reviews are positive. Critics complain about the price, and a few customers report gas, bloating, and itching shortly after starting ARMRA’s colostrum supplement, though several others note improvements in digestive symptoms.

“I took this product for two days. It caused considerable itching, bloating, and gas,” writes Melanie S., another verified Amazon customer. 
These effects have been observed in pediatric studies, though symptoms seem to be mild and generally go away after a few days of supplementation. One study suggests digestive symptoms may result from the repair processes in the digestive tract. (6, 7)

Elm & Rye prioritizes transparency by publishing all third-party lab results on their website. After examining these results, we believe this unflavored, single-ingredient colostrum supplement is one of the best bovine colostrum supplements on the market.

  • We love that Elm & Rye Colostrum is pure and simple, free from additives, fillers, and artificial ingredients often found in supplements today. However, this quality comes at a much higher price point.
  • Costing $70 for 30 servings, this is the most expensive colostrum supplement in our roundup.

Why we like Elm & Rye Colostrum as best bovine

If quality is your top priority in a bovine colostrum supplement, look no further than Elm & Rye. This colostrum powder is sourced from grass-fed, antibiotic-free cattle and standardized to at least 10% IgG.

The IgG concentration is lower than that of other brands, which may be due to the company’s spray-drying process, which has mixed evidence of its effectiveness at maintaining nutrient concentration. Older research shows that spray drying, which involves quickly drying a liquid with hot gas, may result in dried colostrum powder that retains immunoglobulin concentration and quality. However, newer evidence shows that it may not be as effective as once thought at preserving these proteins compared to freeze drying. (8, 21)

“It’s important to note that overdrying can alter binding properties so minimizing any extra drying than needed is important,” adds Burgess. 

Each one-scoop serving of this colostrum powder contains 2,000 mg of pure bovine colostrum without artificial additives, colors, or preservatives. Despite being labeled as unflavored, Elm & Rye says the supplement has a mild, sweet flavor that easily mixes into beverages, smoothies, and foods.

We appreciate that Elm & Rye utilizes third-party testing and displays lab results, including IgG concentration, on the company website for added transparency. 

At $2.33 per serving, Elm & Rye Colostrum is priced significantly higher than other brands we’ve reviewed. Opting for a monthly subscription will save you 25%, lowering the price per serving to $1.75. You can cancel, skip, or change your subscription at any time.

Bloom Colostrum & Collagen supplement supplies 1,000 mg of bovine colostrum standardized to 40% IgG, the highest concentration in our review. It also includes a blend of probiotics, vitamin B12, and collagen, which may help support skin, hair, and gut health.

  • Bloom Colostrum & Collagen is a decent-quality all-in-one supplement, but it doesn’t provide the same amount of collagen and probiotics that you’d normally get if you purchase them separately. The best collagen supplements generally provide at least triple the amount of collagen found in this supplement.
  • At $1.20 per serving, this supplement is on the higher end of pricing for colostrum supplements. 
  • If you’re looking for a colostrum supplement with a high IgG concentration, probiotics, and collagen to support gut health, you may find value in Bloom Colostrum & Collagen.

Why we like Bloom Colostrum & Collagen Peptides as best for hair growth

Bloom Colostrum & Collagen Peptides is an unflavored colostrum supplement featuring a unique blend of colostrum, collagen, probiotics, and vitamin B12. It’s designed to support a healthy immune system, hair growth, and gut health, making it our top choice for hair growth.

Note that even though vitamin B12 deficiencies are linked to hair loss, there isn’t any solid research suggesting that any of the ingredients in this supplement improve hair growth when there isn’t a deficiency present. (26) Collagen on the other hand, does show positive benefits for hair growth and strengthening.

Each one-scoop serving contains 1,000 mg of bovine colostrum and is standardized to provide a whopping 40% of the daily recommended amount of IgG antibodies.

Additionally, each serving delivers two billion colony-forming units (CFUs) of probiotics from Lactobacillus acidophilus, three grams of grass-fed bovine collagen, and covers 150% of the Daily Value (DV) for vitamin B12—a vitamin important for maintaining healthy blood and nerve cells.(23)

The best probiotics for women and men can promote gut health by restoring the normal, healthy balance of bacteria in the digestive system. Studies link imbalances in the gut microbiome—known as dysbiosis—to chronic diseases, including diabetes, obesity, and inflammatory bowel disease (IBD). (9)

More specifically, research shows Lactobacillus strains may be one of the best probiotics for weight loss in overweight individuals. (20)

Although a minimum of one billion CFU is recommended, data shows that a slightly higher dose of five billion CFU may be more effective for improving digestive conditions. (10)

Data shows supplementation with as little as 2.5 g of collagen per day may help improve skin elasticity and hydration and reduce wrinkles. Despite being a key component of hair, research on the benefits of collagen for hair growth is limited. (11)

The supplement’s blend of collagen and colostrum may work together, with some data suggesting that growth factors and other bioactive compounds in colostrum may stimulate collagen production. However, further studies are needed to confirm whether taking collagen and colostrum together offers additional benefits. (12)

According to Bloom, this colostrum supplement is third-party tested to ensure it’s free of heavy metals, pesticides, microbes, and gluten.

What customers are saying

On Amazon, Bloom Colostrum & Collagen Peptides is highly rated. Customers like that it’s flavorless and dissolves easily into beverages. Several reviewers say they have seen improvements in their skin, hair, and digestive health.

“I started using this collagen supplement for a while now and I have noticed an incredible difference in my gut health. I’ve experienced significantly less bloating overall. Since it’s flavorless, it’s easy to mix with anything—I usually just drink it with my protein after the gym and before my meal. One of the standout benefits has been the improvement in my skin and hair. I’ve seen a significant difference since incorporating this supplement into my routine.”

Andy J., Amazon

However, some customers report experiencing gas and/or bloating after consuming Bloom Colostrum & Collagen Peptides.

“After taking this supplement for a few days, I started noticing stomach discomfort and a little bloating. This is likely due to the probiotics, which I have had issues with before. The product appears to be of good quality/mixes well, but the servings are expensive for the quantities of collagen and colostrum. If you are looking for collagen/colostrum/and a probiotic 3-in-1, this could be a great option, though I will probably look at stand-alone supplements for myself going forward,” notes Mark L., another verified Amazon reviewer.

  • Unique to goat colostrum is its high amount of A2 beta-casein proteins, which some studies suggest may be easier to digest than A1 beta-casein found in cow colostrum. (13, 24)
  • At $1.47 per serving, Mt. Capra Goat Milk Colostrum is priced above average for colostrum supplements, but it’s one of the few quality goat milk options available.
  • Mt. Capra Goat Milk Colostrum may be a good choice for someone who has difficulty digesting cow colostrum.

Why we like Mt. Capra Goat Milk Colostrum as best goat colostrum

Mt. Capra specializes in high-quality goat milk products, offering everything from meal replacements to collagen and colostrum supplements. If you’re in the market for a cow-free colostrum supplement, Mt. Capra has you covered.

Compared to cow’s milk colostrum, which contains primarily A1 casein proteins, goat milk colostrum generally contains higher amounts of A2 casein proteins, which limited evidence suggests may be easier to digest. (13, 24)

Each two-scoop serving supplies 2,900 mg of 100% grass-fed, goat milk colostrum collected within 48 hours postpartum. 

It’s free of additives, preservatives, and artificial ingredients and gently processed using Refractance Window Drying (RWD) technology to preserve its bioactive compounds. This unique dehydration method uses infrared light, rather than direct heat, to remove water from heat-sensitive food products.

Studies show that this low-temperature method is more effective at preserving products’ aroma and nutritional properties over drum drying, freeze-drying, spray drying, and other drying methods. (14)

Although it doesn’t quite match the nutritional profile of human colostrum, studies have shown that goat colostrum is still a rich source of immunoglobulins, lactoferrin, growth factors, vitamins, and minerals. (15)

Unfortunately, Mt. Capra Goat Milk Colostrum supplements aren’t third-party tested for purity or potency, so it’s difficult to really know what we’re getting.

At $1.47 per serving, we’d like to see more brand transparency, though we appreciate that the company has a medical advisory board to help ensure quality. Additionally, purchases directly from Mt. Capra’s website come with a 30-day money-back guarantee.

What customers are saying

On Amazon, Mt. Capra Goat Milk Colostrum has over 600 reviews, earning high marks from many customers.

“I can not tolerate cow’s milk, so this is an amazing alternative for me. I have not gotten sick all winter, and I’m sure this has helped my immune system. I put two scoops in my smoothie every morning.”

Michelle B., Amazon

However, several buyers mentioned they didn’t notice any difference with the supplement and found it expensive for the small amount provided.

What are colostrum supplements

Colostrum supplements come from the “first milk” produced by cows and other mammals shortly after giving birth. After the colostrum is collected, it’s processed, pasteurized, and dried into capsules or powders that can be mixed with water or other liquids.

Colostrum supplements are often advertised to offer similar benefits human milk colostrum provides to newborns, including immune support and gut health. “Bovine colostrum has been shown to have less lactose which can be useful to those who are lactose intolerant,” adds Burgess.

Benefits of colostrum supplements

Colostrum is rich in bioactive compounds, including antimicrobial compounds, growth factors, immunoglobulins, and maternal immune cells to help protect infants from infection. Colostrum also promotes maturation of the digestive tract and helps it work optimally. (16)

Bovine and goat colostrum have a similar nutrient composition, so it’s thought to offer these same benefits (and more) in adults.

Research is still in its early stages, but colostrum supplements promise to improve immune function, promote tissue repair, and support gut health.

Immune health

Bovine colostrum is rich in immunoglobulins, especially IgG, which are antibodies that fight off infection by neutralizing pathogenic bacteria, viruses, and microbes. (17)
A 2022 review that included 445 total participants found that bovine colostrum supplementation can significantly reduce the occurrence of upper respiratory tract infections (URTIs). The studies in the trial used doses between  42 mg and 60 g, though most trials were performed using doses of at least 10 g per day. This is much higher than what’s in colostrum supplements on the shelves today. (18)

Gut health

Human and animal studies show that cow colostrum supplements may improve gut health by lowering inflammation, strengthening the gut lining, and preventing intestinal permeability. These effects have been more well-studied in athletes with increased gut permeability caused by intense exercise.  (2, 17
Several studies also show that colostrum may help reduce the frequency and severity of infectious diarrhea and alleviate symptoms of digestive diseases, though more human research is needed. (1)

Athletic performance

The compounds in colostrum may be particularly beneficial for athletes. One recent research review noted that the growth factors in colostrum may support faster muscle growth and improve recovery by supporting tissue repair. (3)
Its immunoglobulins may also help promote a strong immune system and reduce the occurrence of infections that athletes may be more susceptible to, like respiratory infections. (3)

Who should take colostrum supplements

While research is in its early stages, athletes, people with inflammatory bowel disease, and those looking for a supplement to support immune health seem to benefit the most from colostrum supplements.

Who should avoid taking  colostrum supplements

Despite their potential benefits, colostrum supplements aren’t for everyone. Anyone with the following conditions or diet restrictions should avoid them or talk with their healthcare provider before use.

  • Dairy allergy: Colostrum is produced from milk, so it shouldn’t be consumed by those with a dairy allergy.
  • Lactose intolerance: Cow colostrum contains significantly less lactose than mature milk, so some people with lactose intolerance may tolerate it well. However, it’s still a good idea to choose a colostrum supplement designed for lactose-sensitive individuals. (8)
  • Vegan diet: Since colostrum is sourced from animals, it is off limits for vegans.

Pregnancy and breastfeeding: Colostrum supplements should be avoided during pregnancy and while breastfeeding until more research is conducted in these populations.

Potential side effects of colostrum supplements

Colostrum supplements are generally safe and well tolerated. Most side effects are mild and generally resolve on their own. The most commonly reported side effects include: (1)

  • Nausea
  • Gas
  • Diarrhea
  • Abdominal discomfort
  • Skin rashes
  • Itching

Taking higher doses may increase the risk of these side effects, so it’s a good idea to start with a lower amount until you see how it affects you, and work up the dose until results are achieved.

Unfortunately, there is insufficient long-term research on colostrum supplements to establish potential long-term side effects.

FAQs

What is the best time of day to take colostrum supplements?

There isn’t an established “best time” to take colostrum supplements. You can take them whenever it’s most convenient for you. Some manufacturers recommend taking it after meals or on an empty stomach, so following the instructions on your supplement label is a good idea.

What is the best colostrum on the market?

The best colostrum supplement is one that works for your budget and lifestyle. We recommend choosing a third-party tested supplement free of artificial colors, sweeteners, and hormones. Though we chose Nutricost Colostrum as Editor’s choice, we advise you to consult your doctor before taking any new supplement.

Is colostrum anti-inflammatory?

Colostrum is a rich source of many anti-inflammatory compounds, especially lactoferrin, which can reduce inflammation by binding to the cell walls of viruses and bacteria and reducing the production of pro-inflammatory substances. (19)

Is colostrum good for joint pain?

The anti-inflammatory compounds in colostrum may theoretically help reduce joint pain and inflammation. (25) However, human research is needed to establish whether colostrum supplements improve joint pain.
