Powerful Nutrients & Vitamins

Grass-Fed Bovine Colostrum

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®)

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®)

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 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.

Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

Your Questions Answered

We suggest mixing it with 6-8 ounces of room-temperature water and drinking it on an empty stomach, i.e., 30 minutes before or 2 hours after a meal. If you cannot take it on an empty stomach, you’ll still get good results taking it with food.

We source our colostrum from grass-fed, pasture-raised farms across the US. It’s free from pesticides, heavy metals, antibiotics, and hormones. It has higher IgG content than competing products (40% vs. 25%). And it’s cold-processed to keep the fragile immunoglobulins and other nutrients intact.

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.

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

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. 

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.

Great transition!

Really loving my transition from old vitamins to taking Adapt Natural supplements. I feel more energized, my skin looks healthier and my digestion is good! So happy I tried them as they are definitely part of my new routine!

great for active people

So far, the colostrum and the omega supplements are my favorite. I am noticing shorter recovery time after hard workouts and an older, low-grade knee injury seems to be completely healed since I started these two supplements together. Also, periodic joint pain seems much improved. Not sure which is contributing more to feeling better but I'm going to keep going with both! Not sure I see much of a difference with my skin/hair, and was already in a good place with gut health so can't really speak to those effects.

Hi Kris, Thank you for sharing your experience with our colostrum and Omega. We hope as you continue to supplement on these two products, you will notice other improvements. Thank you for being an Adapt Naturals supporter!

Amazing gut support!

I’ve been using the colostrum to help heal my gut and I do think it is helping. Even though I can’t tolerate dairy I seem to be doing well with the colostrum.

Hi Dusty, We are happy our Bio-Avail Colostrum is helping with the healing of your gut. Thank you for sharing your experience. All the best on your health journey!

So happy I found this

I was losing hair like crazy and I decided to give this product a try. And it worked. I know longer am losing hair and I see new growth. I can't say it is all do to this product because I also take all the other products that Adapt Naturals has but I really saw a turn around when I added this. And I have had more comments on my skin since taking it. I just wish it came in a larger amount.

Hi Corbi, Thank you for leaving us a review on the Bio-Avail colostrum. Its great to hear you are seeing improvements in your hair and skin. We hope as you continue taking this supplement you will notice other benefits. All the best!
