Are There Side Effects to Taking Colostrum?

Key Takeaways

  • Colostrum is basically nature’s super milk—packed with antibodies and immune-supporting goodies to keep you feeling your best.

  • It can help strengthen your immune system, support gut health, and even boost athletic performance.

  • If you notice any side effects, they’re usually mild (think slight digestive discomfort) and go away as your body gets used to it.

  • If you have a dairy allergy or lactose intolerance, be cautious since allergic reactions are possible.

  • LiveGood Whey Protein Isolate with Colostrum gives you 20g of high-quality protein plus immune-boosting colostrum, sourced from 100% grass-fed, pasture-raised cows for top-tier nutrition and absorption.

Understanding Colostrum

What It Is & Where It Comes From

Colostrum is that thick, golden liquid mammals produce in the first few days after giving birth. It’s packed with immune-boosting nutrients that help newborns thrive.

For supplements, we’re not talking about human colostrum (obviously). Instead, bovine colostrum—aka the stuff from cows—is the go-to. It’s super similar to human colostrum, easy to produce in large amounts, and widely used to support immune health and digestion in adults.

Nutritional Components

Colostrum isn’t just another dairy product—it’s loaded with nutrients that make it seriously powerful. You’ve got your basics like proteins, carbs, fats, vitamins, and minerals, but what really makes it stand out are the bioactive compounds. 

These are the real MVPs when it comes to immune support and overall health. In fact, research has shown that colostrum is exceptionally rich in N-glycosylated proteins, which may serve as a potent source of bioactive glycans.

Colostrum is also packed with immunoglobulins, which are basically antibodies that help your body fight off invaders. Then there’s lactoferrin, an iron-binding protein that makes life tough for bad bacteria in your gut. Growth factors help with tissue repair and muscle recovery, while antimicrobial peptides work to keep harmful microbes in check.

Here's a quick breakdown of the components in colostrum:

  • Proteins: Fuel for muscle repair and growth.

  • Carbohydrates: Keeps your energy levels up.

  • Fats: Supports brain function and cell health.

  • Vitamins and Minerals: Support various bodily functions.

  • Bioactive Compounds: Enhance immune response and promote gut health.

Known Side Effects of Colostrum

For most people, colostrum is totally fine, but like with any supplement, some might experience mild side effects—especially at first.

1. Digestive Issues

The most common complaints? A little digestive discomfort as your body adjusts. You might notice:

  • Bloating: Feeling a bit puffy? It usually passes.

  • Gas: Your gut is getting used to the new nutrients.

  • Diarrhea: A little too much movement? It should settle.

  • Nausea: Not super common, but can happen.

  • Abdominal cramps: Your digestive system working things out.

These are usually temporary and tend to fade as your body gets used to colostrum. Since it’s packed with bioactive compounds like immunoglobulins and growth factors, it can have a direct impact on gut health—which, for some, means a short adjustment period.

2. Lactose Intolerance Concerns

Since colostrum comes from milk, it naturally contains lactose—which can be an issue if your body doesn’t handle dairy well. If you’re lactose intolerant, you might experience:

  • Diarrhea

  • Stomach cramps

  • Bloating

  • Gas

If your intolerance is mild, small amounts of colostrum might be okay. But if dairy wrecks your stomach, you’ll want to be cautious—or look for lactose-free alternatives.

3. Allergic Reactions

Colostrum is a dairy product, so if you have a milk allergy, allergic reactions are possible. Signs to watch for:

  • Skin rashes or hives: 

  • Swelling of the face, lips, or throat

  • Difficulty breathing

  • Anaphylaxis (severe allergic reaction requiring immediate medical attention)

If you have a known dairy allergy, SKIP colostrum unless a doctor gives you the green light.

4. Possible Immune Overstimulation

Colostrum is loaded with immunoglobulins and growth factors—great for boosting immunity. But if you have an autoimmune condition, extra immune activity might not be what you want. Conditions that might be affected include:

  • Multiple sclerosis (MS)

  • Rheumatoid arthritis (RA)

  • Lupus (SLE)

If you have an autoimmune disorder, talk to your doctor before taking colostrum. It might do more harm than good if it ramps up your immune system too much.

5. Interactions with Medications

Colostrum is natural, but that doesn’t mean it plays nice with all medications. Some possible interactions include:

  • Immunosuppressants: Colostrum boosts immune activity, which might reduce the effects of these meds.

  • Antibiotics: Colostrum can impact gut bacteria, potentially affecting absorption.

If you're on any medications, check with your doctor first to make sure colostrum won’t interfere. Better safe than sorry!

Considerations and Precautions

How to Keep Side Effects in Check

Want to enjoy the benefits of colostrum without the discomfort? Here’s how to play it safe:

  • Start slow – Begin with a small dose and work your way up to see how your body reacts.

  • Go for quality – Stick with reputable brands (hint: LiveGood’s Whey Protein Isolate - With Colostrum) to avoid impurities and low-grade fillers.

  • Take colostrum with food – This can help reduce any stomach upset.

  • Listen to your body – If something feels off, stop using it and reassess.

Who Should Probably Skip Colostrum?

Colostrum isn’t for everyone. If you fall into one of these categories, it’s best to hold off or check with your doctor first.

  • Individuals with dairy allergies or lactose intolerance.

  • If you have liver conditions or elevated enzymes, avoid it unless your doctor gives the green light.

  • Pregnant or breastfeeding? Not enough research confirms it’s safe, so check with your healthcare provider first.

Quality and Source Concerns

Reliable Brands

Reliable brands don’t cut corners—they're all about quality and transparency. The best ones are upfront about where their colostrum comes from, how it’s made, and exactly what’s inside. A good rule of thumb? Stick with brands that have a solid reputation and plenty of positive reviews. 

  • Check for certifications from reputable organizations.

  • Customer feedback and independent testimonials can give you real insight into effectiveness and quality.

  • Stick to clean formulas without unnecessary additives or artificial ingredients.

Third-party Testing

A legit supplement should prove what’s in it. Third-party testing means an independent lab has checked that what’s on the label matches what’s actually in the bottle—without any sketchy contaminants. Brands that openly share these results show they’re serious about quality and safety.

Contamination Risks

Contamination can happen during processing, so stick to brands that follow strict quality control. Always check lab test results to make sure your colostrum is free from:

  • Heavy metals

  • Bacteria

  • Unwanted additives

Also, store it right! Keep your colostrum supplement in a cool, dry place away from sunlight so it stays fresh and effective.

Making an Informed Decision

Long-Term Use Perspectives

Sticking with colostrum long-term can keep the benefits going strong, but it’s always a good idea to stay in tune with your body. 

A 2022 review looked at a 90-day study on Lewis rats that were given 3% and 5% bovine colostrum powder. The results? No negative effects on food intake, body weight, or blood markers, which points to colostrum being safe for long-term use. While that’s promising, everyone’s body is different, so monitor how you feel and get regular health check-ups.

Pay attention to how you’re feeling—especially your immune system, digestion, and overall energy levels. If something feels off, regular check-ups and blood work can help catch any issues early. 

If you have liver concerns, keep tabs on your enzyme levels - and if you're prone to allergies or digestive troubles, stay alert for any reactions. Also, think about where your colostrum is coming from—sustainable and ethically sourced options not only support your health but also help protect the planet.

Frequently Asked Questions (FAQ)

What is colostrum?

Colostrum is basically nature’s supermilk! It’s the first milk that mammals (including humans and cows) produce right after giving birth. It’s loaded with antibodies, nutrients, and growth factors that help kickstart a newborn’s immune system. But here’s the cool part—you don’t have to be a baby to benefit from it! Many people take bovine (cow) colostrum as a supplement to boost immunity, support gut health, and even improve athletic recovery.

How do I know if I'm allergic to colostrum?

If you have a history of dairy allergies or lactose intolerance, you may be at risk for an allergic reaction to colostrum. Symptoms can include itching, swelling, hives, or difficulty breathing. If you experience any of these symptoms, discontinue use immediately and seek medical advice.

Is colostrum safe during pregnancy?

If you're pregnant or breastfeeding, check with your doctor first before adding colostrum to your routine. While it has plenty of benefits, you’ll want to make sure it’s the right fit for both you and your baby’s health needs.

Are there any drug interactions with colostrum?

Colostrum may interact with certain medications, especially immunosuppressants. If you're taking medication, consult your healthcare provider to determine if colostrum is safe for you. They can help identify any potential interactions and adjust your treatment plan accordingly.

Why does LiveGood pair colostrum with whey protein instead of offering it as a standalone supplement?
