ARMRA Vs. Wondercow

These days, there’s a lot of hype about colostrum supplements – and for good reason. 

Colostrum is the first milk produced after giving birth, and it has all kinds of nutrients and properties that are absolutely vital when it comes to the growth and development of newborns. 

Because of this rich nutritional profile, colostrum is becoming increasingly popular as a health supplement for people of all ages. They have been shown to improve gut health, boost immunity, enhance athletic performance, increase energy levels, and even slow down the aging process. 

But when it comes to choosing a brand of colostrum supplement, the options can be overwhelming. In this article, we will compare two popular brands of colostrum supplements – ARMRA and WonderCow – and discuss why you should consider taking colostrum supplements.

ARMRA vs. WonderCow: About the Supplements

ARMRA, also known as ARMRA Bovine Colostrum Superfood, is a colostrum supplement that is keto-certified and also gluten-free. Its touted benefits include helping to improve the immune system functioning and gut health, along with boosting brain function. It comes in a packet of powder that can be added, one packet per day, to a glass of cold water. It can also be added to food. It’s sourced from grass-fed cows on family-owned dairy farms.

WonderCow is similar. It is also available in a powdered form, and meant to be added to a beverage. The serving size is a bit different, at two scoops per day, but this can be adjusted as needed. The colostrum for WonderCow’s products comes from sustainable farms that use ethical, humane farming practices.

Who It’s Best For Immunity and whole health supportGut health, immune system support, and muscle growth and repair 

ARMRA is a whole food ingredient that contains over 400+ nutrients and no additives, making it an excellent choice for those who want a supplement optimized for health.

It’s unique because it preserves hundreds of bioactive ingredients in its unique form – its raw, so everything is bioavailable for the maximum immune support. 

ARMRA is backed by research. In studies, it’s shown up to 32% stronger immune protection than comparable products. 

As for downsides, ARMRA is expensive compared to other colostrum products, and its powder has a tendency to get a bit clumpy when you mix it with water. 

WonderCow is a highly concentrated colostrum powder that contains an impressive 40% IgGs, twice the amount found in leading competitors, a factor that ensures maximum effectiveness. 

IgGs are critical in supporting immune system function, fortifying your gut, and promoting overall health and wellness. WonderCow provides many different benefits, some similar to ARMRA, including immune system support, improved gut health, enhanced muscle growth and repair, anti-aging properties, restorative sleep, and cognitive function improvement. 

WonderCow is backed by extensive research and has been shown to provide various health benefits. It is incredibly versatile and easy to use, as it can be added to water, smoothies, protein shakes, or any other beverage of choice. However, it is unflavored, which may not be preferred by everyone. 

And because it is only available in a single size, it may not be convenient for everyone.

Supplement Formulation

ARMRA’s primary ingredient is 1 g of pure colostrum, while WonderCow offers 2000 mg of bovine colostrum and 800 mg of immunoglobulins.

Both supplements contain colostrum, which is the first milk produced by mammals after giving birth. Colostrum is nutrient-rich and contains antibodies that help support the immune system. The natural blood orange flavor in ARMRA is a nice touch, but it doesn’t offer any additional benefits.

WonderCow, however, takes it up a notch by including immunoglobulins. These are specialized proteins that help boost the body’s natural defenses against bacteria and viruses. The addition of immunoglobulins makes WonderCow a superior supplement for immune system support.

While ARMRA’s primary ingredient is pure colostrum, WonderCow includes both colostrum and immunoglobulins. In terms of dosages, WonderCow offers a higher dose of colostrum than ARMRA.


One of the key benefits of colostrum supplements is their ability to improve the body’s immune system. Both ARMRA and WonderCow contain high levels of immunoglobulins, which help fight off bacteria and viruses. 

However, WonderCow takes it a step further by including 2000 mg of bovine colostrum and 800 mg of immunoglobulins, while ARMRA only contains 1 g of pure colostrum.

Immunoglobulins are specialized proteins that play a crucial role in boosting the body’s natural defenses against bacteria and viruses. When it comes to immune system support, WonderCow emerges as the superior supplement due to its higher dosage of both colostrum and immunoglobulins.

Another notable difference between the two supplements is the inclusion of natural blood orange flavor in ARMRA. While this may add to the taste, it again does not necessarily offer any benefits. 

Both ARMRA and WonderCow have the potential to boost the immune system, with WonderCow potentially being a more effective choice due to its higher dosage of key active ingredients.

Customer Feedback and Reviews

Both ARMRA and WonderCow have overwhelmingly positive reviews online. The main complaints about ARMRA are that the powder tends to clump when mixed with water, and that some people have reported skin reactions after consuming it (which is why it’s so important to talk to your doctor before starting any new supplementation regimen).

The major complaint about WonderCow is that the supplement doesn’t have any flavors available, and while it’s not likely to produce major side effects, some people have reported nausea and other digestive upset. Like ARMRA, it also has a tendency to clump up when mixed with water. 

Nevertheless, most reviews for both products are positive (4.1 out of 5 stars on Amazon for ARMRA and 4.5 out of 5 stars on Amazon for WonderCow). 

Other Considerations

Here are a few other things to keep in mind when you’re comparing ARMRA vs. WonderCow.

Company Reputation

ARMRA has a slight edge over WonderCow. ARMRA is a company that prides itself on providing high-quality, well-researched supplements. They have a strong reputation for producing effective products that deliver noticeable results. They’ve been in business since 2020.

WonderCow, while a reliable brand, does not have the same level of recognition or reputation as ARMRA, simply because they are a company that was launched only this year. 

Return Policies

Both ARMRA and WonderCow offer a 30-day return window, so it’s a tie in this area as well. 


Reviewers claim that neither ARMRA nor WonderCow has a taste that’s particularly appetizing – most describe the powders as being somewhat chalky, bland, and gritty. However, since ARMRA does offer one flavor beyond its unflavored formulation, it will take the win here – the blood orange might not be everybody’s favorite, but most reviewers say it’s better than the unflavored option.

Dietary Restrictions

WonderCow is safe for just about anyone, including older adults and children. It is manufactured in a GMP-certified facility. It has no GMO ingredients and is also gluten- and soy-free. 

ARMRA contains added prebiotics and is free from soy, gluten, and sugar. 

For the most part, though not approved by the FDA, these products are safe for just about anyone. The exception is for people who are allergic to dairy products or for those who have hormone-sensitive cancers, since colostrum contains trace amounts of estrogen.

Benefit Preferences

Both ARMRA and WonderCow offer high-quality colostrum supplements that provide a range of benefits for overall health and wellness. 

ARMRA has the advantage of added flavors for a slightly better taste, but WonderCow offers a more potent dose that’s better for people with very specific dietary needs.


At less than $1 per dose, WonderCow’s supplement is significantly more affordable than ARMRA’s, especially when you consider that you’re getting a more potent formulation.

However, the added prebiotics and the blood orange flavor may be enough to push some buyers toward ARMRA, even at a higher price point. It also has been around longer, so may offer the benefit of being a more reputable brand, too.

ARMRA vs. WonderCow: Which Supplement is Better?

So which one is better – ARMRA or WonderCow?

Unless you’re someone who is very easily swayed by a company’s longevity in doing business, then WonderCow will likely come out on top. Both ARMRA and WonderCow have great reviews on Amazon, but WonderCow’s are slightly more favorable, even though they haven’t been in business quite as long. 

WonderCow’s supplements offer a more affordable formulation, and while there’s only one flavor available – which might be off-putting to people who really value the taste of the supplements they take – ultimately, the lower price point is a big selling point on its own. 

If you prefer a supplement that will help a bit more with gut health, ARMRA is the best choice because it has the added prebiotics. 

Whichever you choose, both ARMRA and WonderCow offer excellent benefits as colostrum supplements – consider giving one (or both!) a try today. Additionally, you can learn more about each option by reading our full ARMRA review here and our full Wondercow review here.
