Powerful Nutrients & Vitamins

Grass-Fed Bovine Colostrum

Contains 2.5 grams of cold-processed colostrum from grass-fed cows never given antibiotics, hormones, or GMOs. Colostrum is “Mother Nature’s perfect first food.” It’s the nutrient-rich fluid female mammals produce in the first few days after giving birth. It serves as the first source of nourishment for newborns and is packed with essential nutrients, antibodies, growth factors, and other bioactive compounds. Colostrum nourishes the gut microbiome, supports the mucosal barriers (e.g., gut, skin, lungs, etc.), protects against infections, and modulates the immune response.

Lactoferrin (Bioferrin®)

Contains 100 mg of lactoferrin (as Bioferrin®). Lactoferrin is a protein in the milk, tears, and saliva of mammals. It plays a vital role in defending against microbial invaders, promoting gut health, and enhancing the immune system's effectiveness. It also supports efficient iron metabolism—keeping it away from pathogens that require it and helping us to absorb it more efficiently. Lactoferrin is naturally present in small amounts (~3-5 mg per gram) in colostrum. We’ve included a much larger amount to amplify its benefits and provide better results.

Beta-Glucan (Wellmune®)

Contains 200 mg of beta-glucan (1,3/1,6 as Wellmune®). Beta-glucan is a naturally occurring polysaccharide in yeast, mushrooms, and other foods. It’s known as a “biological response modifier,” a class of compounds that regulate immune function. Beta-glucans help to “train” our innate immune cells, helping them to recognize and respond more quickly and efficiently to threats. Instead of boosting or suppressing the immune system, beta-glucans fine-tune it and restore balance.

Why Choose Bio-Avail Colostrum+?

Bio-Avail Colostrum+ contains 2.5 grams of colostrum per serving—2.5x more than most competitors. This is critical because studies documenting colostrum’s benefits typically use a dose of 2 grams or more. We source our colostrum from grass-fed, pasture-raised farms across the US, and it’s free from pesticides, heavy metals, antibiotics, and artificial growth hormones. And it’s cold-processed to keep the fragile immunoglobulins and other nutrients intact. But we didn’t stop there. We included two more compounds that support gut and immune health: lactoferrin and beta-glucan. Bio-Avail Colostrum+ is the first and only supplement that contains all three of these powerful ingredients. If you were to buy these products separately, you’d be spending well over $100—and taking more powder or pills.

FIGHT PREMATURE AGING

Want to turn back the clock and maintain your youthful glow? Bio-Avail Colostrum+ harnesses the anti-aging benefits of colostrum, lactoferrin, and beta-glucans to help you fight premature aging from the inside out.

The essential nutrients, antibodies, and growth factors in Bio-Avail Colostrum+ slow biological aging by nourishing the microbiome, sealing the gut lining, supporting the immune system, and promoting overall vitality. Lactoferrin defends against threats and promotes a healthy gut environment, while beta-glucans fine-tune your immune response to keep your body's defenses strong and resilient.

The result? A more youthful appearance, increased energy, and unstoppable vitality. Say goodbye to premature wrinkles, dull skin, and brittle hair and nails. With Bio-Avail Colostrum+, you can unlock your body's innate ability to heal, regenerate, and thrive.

Formulated to Rebuild Gut and Immune Health

From processed food to environmental toxins to chronic stress, the modern world makes health hard. Bio-Avail Colostrum+ was formulated to rebuild your gut health, fortify and strengthen your immune defenses, and restore immune balance. Supporting the “gut-immune axis” is one of the most important things we can do to improve our overall health and extend our lifespan. Bio-Avail Colostrum+ promotes enhanced vitality, a more youthful and radiant appearance, and greater protection against the challenges of daily life.

Harness Years of In-Clinic Experience and Ancestral Wisdom

Backed by Adapt Naturals' 15 years of in-clinic experience and dedicated to creating supplements that make a meaningful difference, Bio-Avail Colostrum+ combines cutting-edge research with insights from ancestral wisdom to bring you a premium-quality supplement.

Your Questions Answered

What’s the best way to take Bio-Avail Colostrum+?

You can mix Bio-Avail Colostrum+ into both foods and beverages! Recent research suggests that for generally healthy individuals, taking colostrum with food does not significantly impact its absorption or benefits. Feel free to stir it into yogurt, oatmeal, smoothies, or other foods and drinks.

However, we advise against mixing Bio-Avail Colostrum+ into hot beverages like coffee or tea, as high temperatures can degrade the delicate immunoglobulins and other beneficial proteins. Stick with room temperature or cold liquids and foods for optimal results.

If you have diabetes, metabolic issues, or simply find you get better results taking it on an empty stomach, mixing Bio-Avail Colostrum+ with 6-8 ounces of room-temperature water and drinking it 30 minutes before or 2 hours after a meal is still a great option.

Where is your colostrum sourced?

We source our colostrum from grass-fed, pasture-raised farms across the US. It’s free from pesticides, heavy metals, antibiotics, and hormones. And it’s cold-processed to keep the fragile immunoglobulins and other nutrients intact.

I’m lactose intolerant. Can I take Bio-Avail Colostrum+?

While colostrum does contain a minimal amount of lactose, it is generally well-tolerated by people who are sensitive to lactose. We recommend speaking with your healthcare provider before supplementing with Colostrum+ if you are sensitive to lactose.

Does Bio-Avail Colostrum+ contain casein?

Yes, all dairy products (including colostrum) contain casein. We do not recommend taking Bio-Avail Colostrum+ if you have a casein sensitivity or allergy.

Am I depriving newborn calves of colostrum if I take this product?

No. The pasture-based farms we source colostrum from understand the importance of colostrum to developing calves. The calves are fed 2–4 liters of colostrum shortly after birth. New mothers often produce more than 12 liters, so the farmers can harvest this excess colostrum without harming the calves.

How much lactoferrin is in Bio-Avail Colostrum+?

Lactoferrin is naturally present in colostrum at 0.3-0.5%. This equals 3-5 mg per gram, or 7.5-12.5 mg per our 2.5 gram serving. However, Bio-Avail Colostrum+ also includes 100 mg of pure lactoferrin—yielding a total of 107.5 to 112.5 mg of lactoferrin per serving. This is far higher than other colostrum products that do not contain additional lactoferrin.

Is Bio-Avail Colostrum+ third-party tested?

Yes, all Adapt Naturals products, including Bio-Avail Colostrum+, undergo rigorous third-party testing for purity and potency. Most importantly, we transparently share these results with our customers by posting Certificates of Analysis (CoAs) and test results on our website. This level of openness is almost unheard of in the supplement industry. It allows you to see exactly what’s in the product you’re putting into your body.

Bio-Avail Colostrum Works!

I started taking Bio-Avail Colostrum to help support my gut. I've done a cleanse and had been taking Biome Protect for several months with good results of bowel movements, but my stomach and gut were still irritable. If I ate the wrong thing or just daily for no reason, I would get cramping or bloating. Since I started taking this colostrum, my symptoms have almost completely resolved. The only time they recur is if I miss taking it for several days. It has also helped with my skin, providing a smoother, more moist and youthful appearance! I'm very happy with this colostrum and recommend it frequently.

Hi Tara,
Thank you so much for sharing your detailed experience — it means a lot to us! It’s incredible to hear how much Bio-Avail Colostrum+ has helped calm your gut symptoms and even supported your skin health. We’re happy to hear that you notice the difference when you miss it, consistency truly can make all the difference with foundational gut support. We’re honored to be part of your wellness routine, and we appreciate you recommending it to others!

High quality good product

Ive tried 2 different colostrum brands and i love adapt naturals especially that it has lactoferrin. I have noticed stronger nails and less bloating since taking this.

Hi Cindh,

Thank you so much for your kind words! We’re thrilled you’re loving Bio-Avail Colostrum+ and noticing those tangible benefits. Including lactoferrin was intentional to support immune and gut health, and we’re so glad it’s also helping with bloating and nail strength as well. We appreciate your support!

The first month taking Colostrum I was very happy with the bowel movements. I am on my second Colostrum and do not see the same results so I am left to assume I have cleaned out my system.

Hi Catherine,

Thank you for sharing your experience — we really appreciate it. It’s actually quite common for colostrum to support more noticeable digestive shifts early on, especially as it helps strengthen the gut lining and rebalance the microbiome. Over time, many people find that regularity stabilizes at a new, healthier baseline.

That said, if you feel like you’re not seeing the ongoing support you'd hoped for, please remember you're covered by our 60-day money-back guarantee — and we're always here to help troubleshoot or answer any questions that may come up. Take care!

Great product!

I was using the other more popular brand and was having so many issues with fulfillment and switched to Adapt. It has been great!!

Hi Sarah,

We’re so glad you made the switch and that it’s been a smooth experience! Bio-Avail Colostrum+ uses pure, grass-fed colostrum plus lactoferrin and beta-glucan for gut and immune support. We appreciate your trust and are happy to have you with us!

Immune booster

Both my wife and I work in health care and in 18 months I have been taking this colostrum I havent been sick once. Even living in close quarters with my wife when she has brought home bugs I haven’t caught any of them.

Hi Sunny,

Wow — thank you for this sondeful feedback! Bio-Avail Colostrum+ supports mucosal immunity (our first line of defense) through immunoglobulins, lactoferrin, and growth factors, which may help explain your resilience even in close contact settings. We’re honored to support both you and your wife as healthcare workers — thank you for all you do!
