1. Colostrum Supplement Powder Organic (73 Servings) – Best Overall
Why it stands out: This organic bovine colostrum powder delivers a generous 73 servings with comprehensive benefits for gut health, hair growth, beauty, and immune support—all in an unflavored format that mixes easily into any beverage or food.
Made from certified organic bovine colostrum, this powder prioritizes bioavailability and purity over everything else. The unflavored profile makes it incredibly versatile—add it to morning smoothies, stir into your coffee, blend with protein shakes, or simply mix with water. Users consistently report noticeable improvements in digestion, reduced bloating, and improved hair texture within 4-6 weeks of consistent daily use.
The 73-serving count makes this one of the best values per serving in the powder category. Unlike capsules that limit your dosing options, powder lets you adjust based on your goals—maintenance users can take smaller amounts while those doing intensive gut healing protocols can increase their serving size. The organic certification ensures the source cows weren’t treated with antibiotics or synthetic hormones, which matters for a product derived directly from animal milk.
Pros:
- USDA organic certified for clean sourcing

- Unflavored for versatile mixing options
- Multi-benefit formula (gut, hair, skin, immunity)
- Fine powder dissolves easily without clumping
Cons:
- IgG percentage not specified on label
- Requires measuring each dose
Best for: Anyone wanting an all-around colostrum supplement with organic sourcing, flexible dosing, and excellent value per serving.
2. Bovine Colostrum Capsules with Immunoglobulin G – Best for Convenience
Why it stands out: Pre-measured capsules eliminate the guesswork of powder dosing, and the formula includes targeted support for gut health, joints, bones, and brain function—making it a true multi-system supplement.
This capsule formula delivers bovine colostrum with standardized immunoglobulin G (IgG) content in an easy-to-swallow format. Beyond gut health, the manufacturer positions this as a “muscle builder” and includes claims for joint support, bone strength, and cognitive benefits. The growth factors naturally present in colostrum support these broader claims, making this a solid choice for those wanting systemic benefits beyond just gut health.
At 60 capsules per bottle, it’s approximately a one-month supply at typical dosing of 2 capsules daily. Capsules are ideal for travel, office use, or those who simply dislike the taste and hassle of powder supplements. You won’t need to carry a scoop or worry about mixing—just pop the capsules with water and you’re done.

For those new to colostrum supplementation, starting with 50 servings lets you properly assess tolerance and benefits before committing to a larger supply.
The organic certification ensures you’re getting colostrum from cows raised without antibiotics or synthetic hormones—an important consideration given that you’re consuming a product derived directly from milk. At roughly 6-7 weeks of daily use, this size gives you enough time to determine if colostrum works for your body. Many users find their gut symptoms improve within the first month, giving you a clear indication of whether to continue with a larger size.
Pros:
- USDA organic certified for quality assurance
- Lower upfront cost for risk-free trial
- Same quality and sourcing as larger sizes
- Unflavored and versatile for any beverage

- Smaller container less economical long-term
Best for: First-time colostrum users wanting to test the waters, or those on a tighter budget who can’t commit to larger containers upfront.
4. Bovine Colostrum Powder 3000mg IgG – Best High-Potency
Why it stands out: With 3000mg of IgG per serving and grass-fed, freeze-dried processing, this is one of the most potent colostrum powders available for those seeking therapeutic-level benefits.
Potency matters significantly with colostrum supplementation, and this formula delivers in a big way. The 3000mg IgG dosage is substantially higher than standard products, making it ideal for those with specific gut healing goals, compromised immunity, or autoimmune-related digestive issues. This isn’t a maintenance supplement—it’s designed for people who need serious colostrum support.
Grass-fed sourcing means the source cows ate their natural diet, resulting in a superior fatty acid profile and higher nutrient density in the colostrum. The freeze-drying process (vs. conventional spray-drying) uses low temperatures that preserve heat-sensitive growth factors, immunoglobulins, and lactoferrin that high-heat processing destroys. The 50-serving supply at this potency level offers solid value for what is admittedly a premium product. Users with leaky gut, post-antibiotic gut restoration needs, or chronic digestive issues report the strongest results with high-potency formulas like this.
Pros:
- 3000mg IgG per serving (significantly higher than standard)
- Grass-fed sourcing for superior nutrient profile
- Freeze-dried to preserve bioactivity and growth factors
- Supports gut, hair, immunity, and muscle recovery
- 50 servings per container
Cons:
- Higher price point than standard colostrum
- Potency may be excessive for general maintenance use
- Taste can be stronger due to concentration
Best for: Those seeking maximum therapeutic benefit from colostrum for serious gut healing or immune support needs.
5. Double Wood Colostrum Capsules – Best Third-Party Tested
Why it stands out: Double Wood’s commitment to independent third-party testing and their exclusive use of first-milking-only colostrum sets this apart for quality-conscious consumers who want verified potency.
First milking colostrum contains the highest concentration of immunoglobulins because it’s collected in the initial hours after birth when antibody content peaks. Double Wood exclusively sources this premium material rather than mixing in later milkings that dilute potency. Each serving delivers 1,000mg standardized to contain 15% IgG immunoglobulins—clearly labeled so you know exactly what you’re getting with each dose.
The 120-capsule count (2 capsules per serving) provides a full 2-month supply, making this economical for long-term use. Double Wood is known in the supplement industry for rigorous quality control, and this product undergoes third-party testing for purity, potency, and contaminants. No fillers, no binders, no artificial anything—just colostrum in a capsule. For buyers who’ve been burned by underdosed or mislabeled supplements, this transparency is worth the modest premium over untested alternatives.
Pros:
- Third-party tested for quality assurance and label accuracy
- First milking only (highest natural IgG content)
- 15% IgG standardization clearly disclosed
- No fillers, additives, or artificial ingredients
- 120 capsules provides 60 servings (2-month supply)
Cons:
- 15% IgG is lower than some concentrated competitors
- Capsule form limits dosing flexibility
- First milking sourcing means higher cost
Best for: Quality-focused buyers who prioritize transparency, testing, and knowing exactly what’s in their supplements.
6. Double Wood Colostrum Powder – Best for Athletes
Why it stands out: Standardized to 30% total immunoglobulins AND 60% protein, this powder is uniquely optimized for muscle recovery and athletic performance alongside standard immune support benefits.
Athletes and bodybuilders have used colostrum for decades due to its natural growth factors and protein content—compounds that support muscle recovery, reduce exercise-induced gut permeability, and help maintain training consistency. This Double Wood powder takes that legacy seriously with 60% protein standardization, which is rare in the colostrum market where most products don’t even disclose protein content.
The 120-gram container provides a 60-day supply at standard dosing, and the powder format allows flexible dosing based on training intensity. Heavy training days might warrant larger servings, while rest days could use maintenance doses. Mix post-workout for recovery benefits or take in the morning for daily immune support. The 30% immunoglobulin content ensures you’re still getting meaningful immune benefits while the protein content supports your training goals. Athletes report reduced illness frequency during heavy training blocks and faster recovery between sessions.
Pros:
- 30% immunoglobulins + 60% protein (dual-benefit formula)
- Optimized for muscle recovery and athletic performance
- 60-day supply for long-term use
- Flexible powder dosing for training cycles
- From a trusted, quality-focused brand
Cons:
- Unflavored taste may be “milky” or chalky to some
- Athletes doing heavy training may prefer larger serving counts
- Not organic
Best for: Athletes, bodybuilders, and fitness enthusiasts seeking recovery support and immune benefits in one supplement.
7. Vitamatic Bovine Colostrum 30% IgG – Best Value
Why it stands out: With 180 vegetarian capsules containing 30% IgG standardization, this delivers one of the best cost-per-serving ratios in the entire capsule colostrum market.
At 1500mg per serving with 30% IgG, Vitamatic delivers meaningful therapeutic dosing at a price point that makes long-term supplementation sustainable. The 180 vegetarian capsule count means this single bottle lasts 2-3 months depending on your dosing schedule—dramatically reducing your cost per month compared to smaller bottles that need frequent replacement.
Benefits span the full colostrum spectrum: gut health support, hair growth stimulation, beauty from within, muscle recovery enhancement, and immune system strengthening. The vegetarian capsules (meaning the shell itself, not the contents) use plant-based materials rather than gelatin, making this suitable for those avoiding animal-derived capsule shells for religious or personal reasons. Note that the colostrum inside is still bovine-derived—this isn’t a vegan product, just one with a vegetarian-friendly delivery method. For anyone planning to take colostrum daily for months or years, the economics of this bottle make it a clear winner.
Pros:
- 180 capsules per bottle (exceptional long-term value)
- 30% IgG standardization—double many competitors
- 1500mg per serving for therapeutic dosing
- Vegetarian capsule shells (plant-based, not gelatin)
- Multi-benefit support across gut, immune, hair, skin
Cons:
- Not certified organic
- Capsule contents are still bovine-derived (not vegetarian inside)
- Large capsule count means larger bottle size
Best for: Cost-conscious buyers wanting quality colostrum with transparent IgG levels and long-term value.
8. Bovine Colostrum for Women – Best for Women
Why it stands out: Specifically formulated and marketed for women’s health priorities, with premium first-milking sourcing and low-heat processing to maximize the bioactive compounds women need most.
While colostrum benefits everyone regardless of gender, this product is specifically tailored for women’s health concerns including hormonal balance support, gut health (which affects everything from mood to skin), immunity during high-stress periods, and overall vitality. The marketing and formulation focus on the concerns women most commonly bring to colostrum supplementation.
The 1,000mg per serving with 30% IgG immunoglobulins comes exclusively from first milking—the most nutrient-dense collection period when antibody and growth factor concentrations peak. Low-heat processing preserves the bioactive compounds that high-heat spray-drying destroys, including lactoferrin and various growth factors that support tissue repair and gut lining integrity. Made in the USA under strict quality controls and non-GMO verified. The 30-serving count works well as a monthly supply at standard dosing.
Pros:
- First milking colostrum (highest natural potency)
- 30% IgG immunoglobulins standardized
- Low-heat processed to preserve bioactive compounds
- Made in USA with non-GMO verification
- Formulated with women’s health priorities in mind
Cons:
- Only 30 servings per bottle (need monthly reorders)
- Premium pricing per serving compared to bulk options
- Smaller bottle size reduces long-term value
Best for: Women seeking a colostrum supplement specifically designed for female health priorities including gut health, immunity, and vitality.
9. Bovine Colostrum Powder 60% IgG – Best Premium Option
Why it stands out: At an impressive 60% IgG concentration with 3000mg per serving, this is the highest-potency colostrum we’ve found—designed for therapeutic applications where maximum strength matters.
When standard colostrum isn’t delivering results, or when you’re dealing with significant gut healing challenges, this 60% IgG formula delivers serious immunoglobulin content that lesser products can’t match. Most colostrum supplements contain 15-30% IgG—this one doubles the high end of that range. For people with leaky gut syndrome, severe digestive dysfunction, or compromised immunity, this concentration makes a meaningful therapeutic difference.
Organic grass-fed sourcing ensures the source cows ate their natural diet without pesticide-laden grains or feedlot conditions. Low-temperature freeze-drying preserves the delicate bioactive compounds—growth factors, lactoferrin, and proline-rich polypeptides—that high-heat processing destroys. The unflavored powder mixes easily into any beverage without altering taste significantly. At 3000mg per serving across 50 servings, this is positioned for those with significant gut healing goals or substantially compromised immunity who need the strongest available colostrum support.

10. Colostrum Powder with IgG Antibodies – Best Clean Formula
Why it stands out: A straightforward, whole-food approach with no additives, fillers, or unnecessary ingredients—just pure colostrum and its natural IgG antibodies the way nature intended.
Sometimes less is more, and this unflavored colostrum powder embraces that philosophy completely. The clean formula contains just bovine colostrum with naturally occurring IgG antibodies—nothing added, nothing taken away, nothing to worry about. No flow agents, no anti-caking compounds, no artificial anything. For ingredient-conscious consumers who read every label and question every additive, this simplicity is exactly what they’re looking for.
The whole-food nutrition approach means you’re getting colostrum as close to its natural state as possible while still being shelf-stable and convenient. At 60 servings, it’s a solid 2-month supply for daily maintenance use. The unflavored powder dissolves reasonably well and doesn’t significantly alter the taste of beverages.

Best for: Ingredient-conscious consumers who prefer whole-food supplements with nothing extra and value simplicity over concentration.
What is Colostrum and Who Should Take It?
Colostrum is the first milk produced by mammals in the initial 24-72 hours after giving birth. It’s dramatically different from regular milk—packed with immunoglobulins (especially IgG), lactoferrin, growth factors, and proline-rich polypeptides (PRPs) that help newborns develop immune function and establish healthy gut microbiomes. Bovine (cow) colostrum is remarkably similar to human colostrum in composition and is the source for all commercial supplements. The immunoglobulins in colostrum help seal the gut lining and modulate immune responses.
People typically benefit most from colostrum if they experience leaky gut or chronic digestive issues like bloating, irregular bowel movements, or food sensitivities. Those with frequent colds, weakened immunity, or recovering from illness often see immune benefits. Athletes seeking faster recovery between training sessions have used colostrum for decades. And increasingly, people wanting to support skin elasticity and hair health from within are turning to colostrum for its growth factors. It’s particularly popular among those following gut-healing protocols, recovering from antibiotic use, or dealing with autoimmune-related digestive symptoms.
How to Choose the Right Colostrum Supplement
Key Ingredients to Look For
The most important factor is IgG (immunoglobulin G) content—look for products standardized to at least 15-30% IgG for general use. Higher percentages (40-60%) indicate more concentrated formulas designed for therapeutic applications like serious gut healing. First-milking colostrum contains the highest nutrient density because antibody concentration peaks immediately after birth and declines with each subsequent milking. Grass-fed sourcing suggests better overall quality since pasture-raised cows produce colostrum with superior fatty acid profiles. Some premium products also standardize for lactoferrin (an antimicrobial compound) and PRPs (proline-rich polypeptides that modulate immune function), though IgG remains the primary quality marker most consumers should focus on.
Forms Compared
Powders offer the most flexibility and typically the best value per serving—you control the exact dose and can increase or decrease based on your needs. They mix into beverages but require measuring and may have a mild milky taste. Capsules provide convenience and consistent dosing without taste concerns but cost more per gram of colostrum and limit your ability to adjust doses. Liquid colostrum exists but is less common, requires refrigeration, and has a shorter shelf life. For therapeutic doses (2-4 grams daily), powder is most practical and economical.
What to Avoid
Skip products that don’t disclose IgG percentage—without this information, you can’t assess potency and may be paying premium prices for diluted colostrum. Avoid products processed with high heat (conventional spray-drying at high temperatures destroys immunoglobulins and growth factors). Watch for excessive fillers like maltodextrin, silicon dioxide, or magnesium stearate that add weight without adding benefit. Be skeptical of suspiciously low prices that may indicate diluted product, blended milkings, or inferior processing methods.
Side Effects and Precautions
Most people tolerate colostrum well with no adverse effects. However, some experience mild digestive upset initially—particularly those with existing gut issues or sensitivities. This often manifests as bloating, gas, or loose stools in the first few days. Paradoxically, this sometimes indicates the colostrum is working to shift gut bacteria and heal the intestinal lining. These effects typically resolve within a week as the gut adjusts to the new supplement. Starting with a half dose and gradually increasing over 1-2 weeks helps minimize this transition period and lets your system adapt comfortably.
Those with dairy allergies should approach bovine colostrum cautiously or avoid it entirely. While colostrum is lower in lactose than regular milk and most lactose-intolerant individuals tolerate it fine, true dairy allergies (to casein or whey proteins) may cause reactions. Pregnant and nursing women should consult their healthcare provider before use, though colostrum is generally considered safe. If you have an autoimmune condition, discuss colostrum supplementation with your doctor first—immune-modulating supplements require professional guidance in these cases to avoid potential flare-ups. Some practitioners recommend cycling colostrum (taking breaks every few months) rather than continuous long-term use, though research on this approach is limited.
FAQs
How much colostrum should I take daily? Most research uses 1-3 grams daily for general health maintenance, while therapeutic protocols for gut healing or immune support may go up to 4-6 grams. Start with 1 gram daily for the first week, then increase based on tolerance and goals. Consistency matters more than high doses—taking 2 grams daily for months will outperform taking 6 grams sporadically.
When is the best time to take colostrum? Take colostrum on an empty stomach for best absorption—ideally first thing in the morning, at least 30 minutes before eating, or 2 hours after your last meal. Some people split doses between morning and evening for sustained benefits throughout the day. Avoid taking it with hot beverages over 110°F, as heat can damage immunoglobulins and growth factors.
How long until I notice benefits from colostrum? Immune benefits like fewer colds may appear within 1-2 weeks of consistent use. Gut health improvements—reduced bloating, better digestion, more regular bowel movements—typically take 4-8 weeks of daily supplementation. Hair and skin benefits require the longest timeline, often 2-3 months or more before visible changes. Be patient and stay consistent rather than increasing doses prematurely.
Can I take colostrum if I’m lactose intolerant? Yes, in most cases. Colostrum is very low in lactose compared to regular milk—roughly 2-3% versus 4-5% in whole milk. Most lactose-intolerant individuals tolerate colostrum without issues. However, if you’re highly sensitive or have severe lactose intolerance, start with a small dose and monitor your response before increasing.
Does colostrum interact with medications? Colostrum has no known major drug interactions and is generally safe to take alongside most medications. However, because it modulates immune function, those on immunosuppressant medications (for organ transplants, autoimmune conditions, etc.) should consult their doctor before starting. The growth factors in colostrum are considered safe at supplemental doses and aren’t associated with interactions.
Is bovine colostrum safe for children? Bovine colostrum is used in some pediatric immune support protocols and children’s supplements, but dosing differs substantially from adults. Children under 12 should use significantly lower doses than adults, and any supplementation should be discussed with a pediatrician first. Some children’s immune formulas include colostrum at appropriate pediatric doses.
Final Verdict
For most people, the Colostrum Supplement Powder Organic (73 Servings) offers the best combination of quality, value, and versatility. Its organic certification, generous serving count, and multi-benefit formula make it our top recommendation.
Budget-conscious buyers should consider the Vitamatic Bovine Colostrum 30% IgG for its exceptional 180-capsule count and transparent IgG standardization. For therapeutic use or serious gut healing, the Bovine Colostrum Powder 60% IgG delivers maximum potency. Athletes will appreciate the Double Wood Colostrum Powder for its protein content alongside immune benefits.
