IMPORTANT: Before you pay up to $89.99 for a jar, read this. The biggest scoop in our comparison is 20 grams. The smallest is 1 gram. But scoop size didn't decide our #1. What decided it was how much each brand lets you verify before you buy.
Colostrum Is Everywhere Now. That's Exactly Why It's Easy to Overpay.
A few years ago, colostrum was a word you heard on a dairy farm.
Now it sits on wellness shelves in jars from $39.99 to $89.99, with scoops from 1 gram to 20 grams and labels that all sound about the same.
So how do you tell a well-sourced, tested colostrum from one that just has a nice label?
You stop looking at the scoop and start looking for three things most brands don't give you all at once.
The 3-Box Test (and Why the Biggest Scoop Didn't Win)
Box 1: Where does it come from? A named source, like U.S. Grade A, tells you more than a generic line about quality cows.
Box 2: How much IgG is in it? IgG is one of the main compounds colostrum is known for. A labeled percentage lets you compare one jar to the next.
Box 3: Is every batch tested? Independent testing turns a quality claim into something you can check.
Some brands give you one box. Some give you two. In our comparison, only one gave us all three.
What Colostrum Can (and Can't) Do for You
Straight talk, before we get to the rankings:
Can provide naturally occurring immunoglobulins and other colostrum compounds.*
Can add bovine colostrum to a daily nutrition routine.*
Can't replace medical treatment, a balanced diet or professional advice.
Can't guarantee the same result for every person.
If a brand promises you more than this, be careful. Now let's look at how to compare the jars in front of you.
The 5 Questions That Separated the Winner From the Rest
We scored every powder on the same five things. Take this list with you and use it on any jar you're thinking about buying.
Ask these before you buy:
How many grams of colostrum are in one serving?
Is the IgG percentage on the label, or only in the marketing?
Where does the colostrum come from, and does the brand say?
Is it independently tested, and how often?
What does a gram cost at the serving you'll take?
One powder came out ahead on almost every question. You'll see which one below, plus the cheaper option that gave it a real fight.
What to Look For Before You Buy
Grams per serving: Compare the actual colostrum amount, not just scoop size or jar size.
IgG disclosure: A stated IgG percentage makes potency easier to compare across products.
Sourcing: Look for clear information about farms, grade, feeding practices and country of origin.
Testing: Independent testing and accessible COAs make quality claims easier to verify.
Cost per gram: Compare price against the amount of colostrum you actually plan to take.
4 Red Flags That Should Make You Put the Jar Back
Vague sourcing: Premium pricing deserves more than a generic claim about quality cows.
Hidden potency: If IgG is a selling point, the percentage should be easy to find.
Price-only shopping: A low jar price means less if serving size or sourcing is unclear.
Bigger-is-better: A 20 g serving fits some buyers, but not every daily routine or budget.

Pros
2,000 mg clearly stated per scoop
Pasture-raised Grade A U.S. source
Labeled at 25% IgG
Every batch independently tested
ISO/IEC 17025 lab standard
One ingredient in unflavored
Cons

Contains milk
Powder requires mixing
Bottom Line
Earth Energy didn't win with the biggest scoop. It won because you can check almost everything about it.
Each scoop gives you 2,000 mg of pasture-raised, Grade A U.S. bovine colostrum, labeled at 25% IgG. An independent lab tests every batch to the ISO/IEC 17025 standard. And the unflavored version has exactly one ingredient: colostrum.
The honest part: Nutricost gives you more colostrum per serving (3 g) for less money ($43.97). If dose per dollar is all you care about, compare the two side by side. But if you want a named U.S. source, a labeled IgG and testing on every batch in one jar, start here: $59.95 for a 60-serving jar, or as little as $35.97 a jar when you buy 3 and get 2 free, rated 4.74/5 by 107 customers, with a 30-day guarantee.
Nutricost is the toughest value competitor in this group. You get 3 g per serving, a minimum 30% IgG, independent ISO-accredited testing and a $43.97 price. For shoppers focused on measurable dose per dollar, it may be the most attractive option here. It ranks just below Earth Energy because its sourcing story is less specific, while Earth Energy identifies pasture-raised Grade A U.S. colostrum and provides batch-level testing detail.
1,000 mg grass-fed bovine colostrum per serving sourced from Grade A U.S. dairy farms; 120 servings.
Daily serving
Unflavored powder; non-GMO, soy-free, gluten-free
Price
$54.99 one-time; 120 servings
Ratings
30-day money-back guarantee
Pros
Grade A U.S. dairy sourcing
Grass-fed bovine colostrum
120 servings per container
Calves' needs met first
Cold-chain pasteurized
One-ingredient formula
Cons
1 g standard serving
IgG percentage not clearly disclosed
Testing details less prominent
Bottom Line
Codeage is attractive if you want a smaller daily serving and a jar that lasts. Its 120-serving format, Grade A U.S. dairy sourcing, grass-fed claim and calf-first sourcing are genuine strengths. The trade-off is transparency around IgG and testing compared with the top two. It ranks third because Earth Energy and Nutricost make potency and outside testing easier to compare directly.
1.5 g bovine colostrum plus ImmunoLin per serving, with 30% IgG claimed by the brand.
Daily serving
Powder; unflavored and flavored options
Price

Ratings

Pros
30% IgG claimed
Adds ImmunoLin
Grass-fed colostrum
Multiple flavors
30-day guarantee
Lower entry price
Cons
Formula is not pure colostrum alone
Testing details are less prominent
Serving composition needs closer reading
Bottom Line
Miracle Moo stands out because it combines bovine colostrum with ImmunoLin rather than selling plain colostrum alone. That makes it genuinely different, and its lower entry price will appeal to many shoppers. The trade-off is a less apples-to-apples formula and less visible testing detail. It ranks below Earth Energy because Earth Energy is simpler to evaluate as a whole-colostrum product with named sourcing and batch testing.
Transparent Labs is the outlier here. Its 20 g serving is far larger than the rest of the field, and the company publishes third-party purity testing. That makes it worth a serious look for athletes specifically seeking a high-dose routine. The trade-off is an $89.99 price and a serving size that may be unnecessary for general wellness shoppers. It ranks fifth because this comparison rewards everyday fit as well as potency.
Want the most colostrum per dollar? Nutricost gives you 3 g per serving for $43.97. Want an athlete-size serving? Transparent Labs delivers 20 g, at $89.99.
Want a jar that lasts? Codeage gives you 120 servings. Want colostrum plus ImmunoLin? That's Miracle Moo.
But if you want to know where your colostrum comes from, how much IgG it carries and that every batch gets tested, Earth Energy is the one we'd start with.

Questions people ask
What should I look for in a colostrum powder?
Compare grams per serving, IgG disclosure, sourcing, outside testing and cost per gram. Those five details make products easier to judge than brand language alone. Also check the ingredient list and allergen statement because bovine colostrum is dairy-derived and contains milk.
Is a higher colostrum dose always better?
No single daily amount is established for every purpose. Transparent Labs uses 20 g per serving, while several general-wellness products use 1 to 3 g. A higher dose may fit a specific performance goal, but it also changes cost, jar size and routine. Compare dose in the context of how you plan to use it.
Why is Earth Energy ranked first if you own it?
We disclose that ownership on every page. Every product is scored on the same published criteria, and we show the label details and prices we compared so you can check our work.
Is Nutricost better value than Earth Energy?
On raw grams and current jar price, Nutricost is very competitive: 3 g per serving, minimum 30% IgG and $43.97. Earth Energy ranked higher overall because our scoring also gives substantial weight to sourcing specificity and batch-level testing transparency. If price and dose matter most to you, Nutricost deserves a close look.
Does colostrum contain dairy?
Yes. Bovine colostrum is derived from cow's milk and contains milk. Anyone with a milk allergy should avoid it. If you are pregnant, nursing, giving it to a child, taking medication or managing a medical condition, ask a qualified healthcare professional before using a colostrum supplement.
