Why Earth Energy ranked #1
Earth Energy ranked #1 at 9.4/10 because it balances the factors we weighted most heavily: pasture-raised Grade A U.S. sourcing, a clearly stated 2 g serving, 25% IgG, one-ingredient unflavored powder and independent ISO/IEC 17025 batch testing. Nutricost beats it on raw dose and price, while Transparent Labs is built around a much larger 20 g serving.
- Named U.S. sourcing. Pasture-raised Grade A U.S. colostrum, collected after calves are fully fed.
- Potency is disclosed. 2 g whole colostrum per scoop, labeled at 25% IgG.
- Batch testing. Every batch tested by an independent ISO/IEC 17025-accredited lab.

Why Earth Energy beat Nutricost
Nutricost is a serious value competitor. It gives you more colostrum per serving, a higher minimum IgG percentage and a lower jar price. Here is where Earth Energy pulled ahead in our scoring:
Nutricost data from its current Colostrum 30% product page, checked October 2026.
What actually matters 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.
Red flags to avoid
- 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.

4.74/5 from 107 reviews; 30-day guarantee
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
- Nutricost gives more grams per serving
- Contains milk
- Powder requires mixing
Final thoughts
Earth Energy does not win by having the biggest scoop. It wins because the product is easy to audit: the source is named, the dose is clear, IgG is disclosed, unflavored is one ingredient, and every batch is independently tested. Nutricost is cheaper and delivers more grams, so value-focused shoppers should compare both. Earth Energy is best for buyers who want the strongest overall balance of sourcing, transparency and everyday usability.

#2. Nutricost Colostrum 30% Powder
Recommended for: Buyers prioritizing dose and price

- Excellent price per serving
- Independent ISO-accredited lab testing
- GMP-compliant manufacturing
- 60-day guarantee
Cons
- Uses globally sourced ingredients
- Less detailed farm sourcing
- Unflavored only on compared page
Our take
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.
#3. Codeage Colostrum Powder
Recommended for: Buyers wanting a small daily scoop
What's inside:1,000 mg grass-fed bovine colostrum per serving sourced from Grade A U.S. dairy farms; 120 servings.

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
Our take
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.
#4. Miracle Moo Colostrum
Recommended for: Buyers interested in ImmunoLin
What's inside:1.5 g bovine colostrum plus ImmunoLin per serving, with 30% IgG claimed by the brand.
Format:Powder; unflavored and flavored options
- Transparency
- 8.3/10

Price:$39.99 current Shop listing for 30 servings

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
Our take
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.
#5. Transparent Labs Grass-Fed Colostrum
Recommended for: Active buyers wanting a 20 g serving
What's inside:20 g grass-fed bovine colostrum per serving with a minimum 20% IgG; 30 servings.
Format:Powder; unflavored and chocolate
- Transparency

- Value
- 7.4/10
Price:$89.99 one-time; 30 servings
Search Transparent Labs on Google23 brand-site reviews; 45-day satisfaction guarantee
Pros
- 20 g colostrum per serving
- Minimum 20% IgG
- Grass-fed bovine source
- Published third-party COA
- 100% pure unflavored colostrum
- Built for active users
Cons
- Highest price in this comparison
- 20 g is more than many buyers need
- Less detailed farm sourcing
Our take
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.
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.
How we compared these supplements
We compared the current product pages and published brand documentation for each formula. We weighted sourcing and testing heavily, then looked at potency transparency, value and how practical the labeled serving is for an everyday routine.
