After Reviewing Dozens of Options, These Are the 9 Best Colostrum Supplements Recommended by Dietitians

We like that this product specifies the amount of lactoferrin present, unlike many other options on the market, and is third-party tested for purity, potency, and safety, with the results available on the website. However, it’s expensive, and we found that the powder requires vigorous mixing or a handheld mixer (especially since hot water is not recommended), as it tends to clump. Despite this, the product’s high-quality formulation and transparency make it our top choice for a colostrum supplement for digestive health.

While most colostrum supplements are unflavored, Armra Immune Revival stands out for its appealing flavors, with four tasty options: blood orange, chai, apricot, and watermelon. The flavored varieties are especially convenient for mixing into water for a refreshing alternative to plain powder.

Armra’s colostrum supplement is available in stick packs, making it easy to take on the go. The product is free from antibiotics, hormones, and unnecessary fillers.

The biggest downside is that flavored options cost $10 more than the unflavored supplement, but the taste, portability, and high-quality formulation may make it a worthwhile investment.

Miracle Moo colostrum powder is an excellent choice for immune health, offering 1.5 g to 3 g of grass-fed colostrum, depending on whether you have one or two scoops. This product also has ImmunoLin, a patented ingredient that contains 50 percent IgG, providing a potent dose of immunity-supporting antibodies.

While the website doesn’t mention third-party testing, an email from customer service confirmed that Miracle Moo undergoes “rigorous third-party testing” to ensure quality and safety. The brand exclusively uses surplus colostrum, ensuring that young calves are fed and well-nourished with the colostrum they need before any is collected for this product.

The powder is unflavored and free of additives, soy, wheat, nuts, and sugar. You can mix one to two scoops into 8 to 12 ounces of water, smoothies, or your favorite recipes (although we did find it can clump if not stirred well). While it may lack the flavor variety of some competitors, Miracle Moo’s high IgG content makes it a top choice for a colostrum supplement for immune health.

Wonder Cow contains 2 g of colostrum per serving, and is made up of 40 percent IgG, which is more than many other colostrum products. It’s also good manufacturing practice (GMP) certified and third-party tested, ensuring that the product meets quality, safety, and purity standards. We especially like that the company adheres to a calf-first policy, which ensures that every calf is fully nourished with the colostrum it needs before any is collected for its products.

You can mix this supplement into a glass of water, blend it into postworkout smoothies, or incorporate it into your favorite recipes. It’s also available in flavors sweetened with monk fruit and stevia, including chocolate, matcha, and elderberry. While not from grass-fed sources, this supplement is our top choice for a colostrum supplement for muscle recovery due to the high IgG content, ethical sourcing, and versatile flavors.

While the product is simple to use, one downside is its texture. Without using a blender or frother, the powder can be chunky when mixed into liquids. “I recommend adding a scoop to plain water, juice, or smoothies or mixing it into yogurt or oatmeal bowls for easy use,” says Durston.

If you’re seeking a cow-free colostrum supplement, Mt. Capra Goat Milk Colostrum is our top choice. Sourced from pasture-raised goats on a family-owned farm, this product is available in capsule or powder form.

For budget-conscious buyers seeking quality colostrum supplementation, Now Foods Colostrum Powder is our most affordable option. “I am a huge fan of Now Foods,” says Thomason. “In addition to following GMP, it also runs 10,000 tests per month on products in-house to ensure quality and purity.”

A single teaspoon delivers 1.4 g of bovine colostrum, which is naturally rich in IgG. This formulation provides the core benefits of colostrum without unnecessary frills, making it a practical choice for those on a budget. The unflavored powder can be easily mixed into water, smoothies, or other beverages, offering versatility.

Archer highlights that Now Foods Colostrum Powder contains milk protein concentrate. “Be cautious if you have a dairy allergy,” she says. While the product is affordable, it does not include some of the advanced features found in higher-end colostrum supplements, such as enhanced bioavailability or added compounds like lactoferrin. Still, Now Foods Colostrum Powder excels in providing a straightforward, affordable option for anyone interested in the potential benefits of colostrum.

According to Durston, “Bloom’s product is an excellent choice for supporting healthy hair, skin, and nails, thanks to its blend of collagen, colostrum, and probiotics.” For these reasons, it’s our top pick for people looking for a colostrum supplement to support hair, skin, and nail health.

The product is third-party tested and free from artificial additives. You can choose unflavored or orange cream (sweetened with stevia). This Bloom product also contains vitamin B12, which some people may not need or want in a colostrum supplement. Still, for an all-in-one collagen and colostrum supplement, Bloom delivers.

For a convenient, easy-to-take form of colostrum, Sovereign Labs capsules top our list. “Colostrum capsules offer an alternative to powder, especially for those who take colostrum on the go or while traveling,” says Durston.

According to Archer, who recommends this product to her clients, “Sovereign Laboratories liposomal colostrum comes from the first milk, after the calf meets its needs, from pasture-raised cows. The colostrum is tested to confirm it does not contain antibiotics, hormones, and herbicides. This liposomal colostrum is flash pasteurized to maintain bioactive substances.” These bioactive substances can include immunoglobulins (such as IgG) and other essential proteins.

While the capsule form is undeniably convenient, the serving size contains less colostrum than powders (although you could easily take more). “Unlike powders, capsules require no mixing with water and are easier to store, making them a hassle-free option for daily use,” says Durston.
