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 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

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.

I’m sure it’s good…but I can’t get it down

I’ve tried this in water, And taking it dry, and I cannot get it down. I’m nervous to try it any other way as I’m sure it will still be difficult to eat it in yogurt or a smoothie. I usually do OK with supplements, so I’m bummed that I’m not doing well with this one

I don't go a day without this

Bio-Avail Colostrum+ has become my favorite supplement! Since taking it, my hair has been healthier, my gut has felt better and feel like my immune system has been at its best. It blends in so easily with water and I've come to enjoy the taste every morning. This is something that I will continue to take for years to come!

Hi TSnow, Thank you for sharing your experience with us. It's great to hear you are noticing a difference in you hair, gut and immune system, we hope as you continue supplementing on the Bio-Avail Colostrum you will notice a greater difference. We appreciate your support to Adapt Naturals!

Excellent product

I have been taking colostrum for about a year now and recognize its effect on my immune system. Recently I switched brands and take adapt naturals bio-avail colostrum. It seems even more effective as I have bi-passed being ill twice. Thanks.

Hi KBCV. We are thrilled to hear you have noticed improvements in your immune system. Thank you for trying our Bio-Avail Colostrum and sharing your experience. All the best!

First month

I've been using Armra for over a year and decided to try Adapt's version. I like what the label says about the quality and consideration of ingredients. I am definitely experiencing the same benefits - feeling good, crazy hair and nail growth and strength. I wish the flavor was as good as Armra; it took about a week to adjust to it. I prefer to dry scoop and then follow with water; drinking close to a liter after in the morning before turning to my cup of coffee.

Hi Sheila, We are indeed pleased to know you are getting the benefits you need from our Bio-Avail Colostrum. Thank you for sharing your experience with us!
